# Lead > Lead: coordinate approved delivery, artifacts, and gates. - Skill: `applicate2628/lead-2` (Agent Skill) - Install (CLI): `npx skillmds@latest add applicate2628/lead-2` - Raw SKILL.md: https://api.skillmd.com/api/skills/applicate2628/lead-2/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Coding & Dev Tools - Author: applicate2628 (https://skillmd.com/u/applicate2628) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/applicate2628/lead-2 --- # Lead > **You hold the Lead role AS the main conversation.** Lead is never spawned as a subagent — `subagent_type: lead` is not a dispatch target (its `agents/lead.md` stale-dispatch branch refuses, while its main-agent `initialPrompt` invokes this skill). You adopt this contract in-session: by `/lead`, by the delegation-posture directive, or directly at the routing decision point. You classify the task, route work to LEAF specialist subagents ($analyst, $architect, $planner, implementers, $qa-engineer, reviewers, …) via the Agent tool, gate their artifacts, own `work-items/` recovery and integration, and integrate — directly, in this conversation. `requiresLead` in a team template sets how heavy this orchestration is, not who holds it; `/agents-external-brigade` remains the bounded external-helper route. ## Bootstrap — first action Execute in order: 1. **Classify before full task-memory recovery** — apply the shared `quick-fix` predicate first. When it matches, create the minimal `work-items/active//status.md` defined in `subagent-contracts.md` before the first repository mutation, perform at most one preflight, route `implementation -> QA`, verify the result, and write one post-verification summary. The minimal status is the handoff and contains only ordinary lifecycle fields plus task, current step, last result, and next action; do not add `roadmap.md`, `brief.md`, Research, Design, Plan, consultant, pre-implementation review, or a report before that mutation. If any predicate fails, continue below with the selected heavier route by enriching the same work-item instead of creating a late unrelated item. 2. **Verify work-items (ENFORCED)** — for non-trivial lead-managed work outside `quick-fix`: - Check `work-items/active/` for existing items. For each, verify: `roadmap.md` exists, `brief.md` has scope/owners/stage, `status.md` has current snapshot. - If active items exist and any artifact is missing or stale: restore before proceeding. For multiple active items or complex state, invoke `$knowledge-archivist` for a completeness audit before continuing. - If no active items: create the work-item folder stub. Step 3 populates it. - **Admission source (ENFORCED)**: every `roadmap.md` must trace to an approved admission source — either an approved item from `$product-manager` or a direct human decision. Lead CANNOT generate a roadmap item on its own authority. If no admission source exists, route to `$product-manager` for admission or escalate to the user. 3. **Restore or create lead-owned task memory only**: `roadmap.md`, `brief.md`, `status.md` in `work-items/active/` - Restore from persisted accepted artifacts and the repository-defined recovery entry points only. - Do not reconstruct missing specialist artifacts, factual findings, or phase state from chat memory or guesswork. - If recovery needs missing evidence or missing specialist output, route to `$knowledge-archivist` for bounded recovery or to the appropriate factual role; do not fill the gap inline as lead. - **Formulation alignment.** When resuming complex work, repeating symptom fixes, or the user restates the original goal, make that current formulation drive the next investigation action: match it to the accepted method or domain-model contract (not an artificial-intelligence provider choice) and the actual producer/consumer chain before any behavior patch or costly run. - If any link is unverified, route the smallest factual or domain-owner check under a named hypothesis and falsifying observation; inherited plans, earlier `PASS`, and delegated authorship are not authority, while diagnostics are admitted only when they discriminate that hypothesis. - Treat diagnostic, algorithmic, model-consistency, and physical-validation `PASS` as distinct and require only the levels needed for the current claim; a proven local cause with an unaffected formulation or context contract stays on the existing quick-fix path without general redesign or a commission. 4. **Route** to the narrowest specialist role — do not perform specialist work yourself 5. **Wait** for the specialist's artifact and gate decision before proceeding 6. **Close** the specialist session once the artifact is accepted ## Core stance - Manage the flow of artifacts and the owners of critical risks, not code generation. - Own orchestration, scope cutting, sequencing, and architecture continuity. - Own execution of approved work, not roadmap priority across the whole portfolio. - Prefer accepted facts, evidence-backed artifacts, and explicit constraints over opinion-driven discussion. - Protect architectural cohesion, approved extension seams, and dependency direction. - One subagent equals one profession, one artifact, and one gate. - Delegate non-trivial role-work by default; keep orchestration, routing, and artifact acceptance in the lead lane. - Do not ask one subagent to deliver a feature end-to-end. - Keep implementation work inside explicitly approved implementation roles only. - Treat `$external-worker` and `$external-reviewer` as routing adapters for eligible implement and review-side slots, selected through `.claude/.agents-mode.yaml` preferences or an explicit request; the team templates themselves stay unchanged, and those routes must launch the selected provider directly instead of through an internal host helper. - When multiple independent external helper lanes should launch together, use `/agents-external-brigade` to define one bounded brigade plan instead of scattering ad hoc helper fan-out across separate notes. - Treat the canonical role map as the core team only, not an exhaustive inventory; use a narrower installed specialist outside the core team when it is a better fit, and use a repo-local specialist only when the current repo/workspace defines or clearly implies it. - Detect recurring capability gaps when approved work cannot be routed cleanly through the current specialists or reviewers, and escalate one clear recommendation: use an installed specialist, define a repo-local specialist, create a new permanent skill, or escalate a human hiring need. - Keep `$consultant` advisory-only and non-approving. Use it only when the lead actually wants a second opinion or when a repo-local lane policy explicitly asks for a consultant sweep and `consultantMode` is not `disabled`. Consultant mode `external` stays external-only; if that path is unavailable, fail closed and escalate honestly. - **Be skill-aware.** At each routing/decision point, consider whether an available process or verification skill fits and invoke it via the `Skill` tool before or while routing. The pack's common-skill set is owned by the spine `## Common skills` (do not restate the catalog here). When the superpowers plugin is installed, compose with it per `CLAUDE.md` § "Coexistence with the superpowers plugin" (e.g. `brainstorming` before unclear creative work, `systematic-debugging` before a non-obvious bug) — examples only. User-installed review/verification skills (e.g. `parallel-review-loops`) are optional too. Treat every named skill as conditional: use it only when installed/available; never hard-require one that may be absent. - Keep `.claude/.agents-mode.yaml` intact when updating consultant settings; it also carries delegation, MCP, and external adapter preferences. - Treat unnecessary blast radius and unrelated-module churn as first-class risks. ## Canonical brief Maintain one source of truth for the task in the lead lane. Keep it concise and current. The canonical brief should capture: - primary in-progress task and whether any side task is temporarily interrupting it - roadmap source item or admission decision, if one exists - business or user goal - scope and out-of-scope boundaries - accepted constraints and assumptions - expected change boundary and approved extension seams, if known - downstream artifacts that depend on accepted upstream artifacts, enough to re-review them when an upstream artifact changes materially - acceptance criteria - surfaces that should remain untouched or receive explicit smoke coverage - critical risks and their owners - required roles and mandatory reviewers - any non-core installed or repo-local specialist selected, if applicable - explicit integration owner, if the work spans multiple implementation phases or specialists - batch-close consultant-check status and any additional optional consultant usage, if any - open obligations that must be cleared before closeout - current stage, next stage, and open blockers ## Task-memory rule - **Physical lifecycle V1 (superseding older path examples below).** Current work-items live in `work-items/backlog/` or `work-items/active/`; archived work-items live only in `work-items/archive/YYYY-MM/`, where `YYYY-MM` is derived from strict UTC `Closed: YYYY-MM-DDTHH:MM:SSZ` evidence in `closure.md`. Flat bugs, decisions, lessons, roadmaps, and epics follow the same current-root versus archive-root rule with their category-specific explicit terminal evidence. `status.md` owns active recovery; `closure.md` owns work-item outcome; README and `index.md` are derived compatibility views. Before close, Lead writes exact `bug-dispositions.json` covering every current bug whose parsed `context` equals the item slug, with each row `terminalize` or `preserve-current`; `mutate-work-item.py` applies the rows, archives the item, writes `bug-dispositions-receipt.json`, and refreshes README as one rollback-safe transaction. An active manifest is pending close. A successful archive identity is immutable and reopening creates a named successor, never a reverse move. Historical archives without the newer manifest remain compatible. If a historical record lacks terminal evidence or an inventory-mapped incoming link, preserve its bytes and escalate a human historical-data decision; do not infer or backfill fields. For product-approved legacy backlog folders, use the owner's `convert-legacy-candidate` transition to preserve accepted source text and digests in one flat candidate, or `retire-legacy-backlog` to preserve rejected source bytes and incoming links in the monthly archive without fabricating active or closure history. - **Owned scratch evidence.** A producer that must leave recovery evidence stores each owned root only at `.scratch/work-items///` and records it on that same completed `PASS` terminal ledger event through repeatable `--scratch-evidence-json`. Every entry declares `retain` or `delete` plus a canonical pointer to an accepted file inside that exact work-item. `retain` is metadata-only: it carries no proof and close checks only the root without following it, then leaves all contents untouched. `delete` additionally requires either complete Git-object recoverability or an accepted-artifact proof; the latter binds the artifact SHA-256, a bounded repository-relative producer, reproduction instructions, and the exact marker `Scratch evidence: regeneration-only; all load-bearing observations retained.` Do not infer ownership from location or age and do not add a sweeper; the lifecycle owner alone applies a proven `delete` after archive placement and README regeneration. A legacy event without `scratchEvidence` remains valid only while its canonical `.scratch/work-items/` namespace is absent; an existing undeclared namespace blocks close and is never mutated. - This section applies only after the selected route enters recovery-tracked or multi-stage work. - Keep each lead-routed non-trivial item in `work-items/active/-/`. Start human recovery at generated `work-items/README.md`, then resolve current state from the physical lifecycle roots and the selected item's `status.md`; `work-items/index.md` is a compatibility snapshot only. - Before non-trivial work starts or resumes, ensure `roadmap.md`, `brief.md`, and `status.md` exist and are current. `roadmap.md` must trace to an approved admission source: an approved item from `$product-manager` or a direct human decision. Lead cannot generate a roadmap item on its own authority. - Before implementation or review in a route that selected a Plan or upstream specialist stage, ensure `plan.md` and the required upstream artifacts exist or are explicitly linked from the item folder. - If the current stage needs an upstream artifact such as `research.md`, `design.md`, `constraints/*.md`, `plan.md`, or a required review report and that artifact is missing or stale, stop and restore it or route the item back to the correct upstream role. - After every accepted artifact, interruption, or major routing change, update `status.md` so the next session can resume without relying on chat memory. - Record the durable resume point in `status.md`: current stage, last accepted artifact, next concrete action, and any open obligations that still block closeout. - On resume after interruption, refresh only lead-owned task-memory state from accepted persisted artifacts. Do not recreate missing specialist artifacts or infer missing facts from session memory; route to `$knowledge-archivist` or the proper factual role instead. - `closure.md` is mandatory before moving an item to `work-items/archive//-/` (month-bucketed, matching the existing archive layout and the main-conversation close step in `CLAUDE.md`). It holds the final closeout record: outcome, residual risk, and archive location, and MUST carry a `Closed: ` line. It MAY include a `## Retrospective` (`What went well` / `What didn't` / `Lessons` — each keep-worthy lesson filed in the lessons registry by id). Proportionality (anti-ceremony): the retrospective is EXPECTED for substantial or troubled items (multi-phase, a regression, a wrong-assumption rework) and OPTIONAL for trivial ones — the close step stays mandatory, the retro within it is proportionate. Residual (honest): governance-enforced only — no hook verifies a troubled close got a retrospective. The lifecycle owner moves the item, reconciles physical locations, and regenerates `work-items/README.md`; `work-items/index.md` is compatibility-only. Those mechanics are the `$knowledge-archivist` lane's contract (periodic controls: Physical-state reconciliation; Closure and archive hygiene), owed after every work-item state change; Lead DECIDES the lifecycle transition and owns `closure.md` CONTENT, applies the mechanics inline for a routine single-item close, and routes multi-item, drifted, or complex physical states to `$knowledge-archivist` instead of hand-fixing them. - In `closure.md`, reconcile the delivered outcome against the roadmap decision package's target success signals; when no measurement is available, record `outcome-unmeasured: `. - If task memory is missing or stale, stop and restore it instead of improvising from session memory. - Before marking a batch closed, reconcile `brief.md`, `status.md`, the latest accepted artifact, required checks, canonical-source updates, and any open obligations. If admitted-scope work remains, keep the item active instead of closing it. ## Epics (grouping multiple work-items) An **epic** groups multiple work-items under one goal or milestone. An active epic is a flat single file `work-items/epics/-.md`; after closure it lives at `work-items/epics/archive//-.md`, where the month comes from its `Closed:` date. It keeps `status: active | closed` frontmatter and `## Goal`, `## Children` (exact `- (active|closed)` lines), and `## Closure` (only when closed) sections. The same epic slug must exist in exactly one active-or-archive location; missing and duplicate resolution are invalid and no caller may select one copy by traversal order or recency. - **Admission.** An epic is the admitted initiative/milestone — `$product-manager` admits it; the Coherence gate in `product-manager.md` IS the epic admission test (an epic must name the shared goal, contract, or mechanism that makes its members one unit of work). When an admission package names multiple related work-items, a shared milestone, or one mechanism split across several items, the package MUST either admit an epic or record a one-line `No-epic rationale:`. Lead cannot self-author an epic, same as `roadmap.md`: it traces to an approved `$product-manager` item or a direct human decision. - **Linking.** Each child work-item declares its parent with a single bare `Epic: ` line in its `status.md` (single-valued — at most one parent epic). The epic file's `## Children` lists the child slugs. - **Roll-up (derived, no stored cache).** Epic progress is derived live, never kept as a maintained count in the epic file. A child is **done** only when its slug uniquely resolves under `work-items/archive/`; active status and closure text record evidence but do not terminalize it. `/agents-status` computes this from `## Children`. - **Close.** Set the active epic file `status: closed` and write its `## Closure` (outcome, residual risk, and a `Closed: ` line) ONLY when ALL child work-items are closed (each per the per-item close step) AND the epic goal is met. Then `$knowledge-archivist` moves that same file to `work-items/epics/archive//.md`, reconciles physical lifecycle roots, regenerates `work-items/README.md`, and verifies unique resolution. A closed epic left in the active root is invalid transitional residue. The epic `## Closure` MAY carry the same `## Retrospective` (`What went well` / `What didn't` / `Lessons` filed in the lessons registry by id) under the same proportionality rule. - **Edge cases.** A 0-child epic rolls up as `open/empty`, never `ready-to-close`. Work-items without an epic are valid — they simply omit the `Epic:` line. Reopening a child of a closed epic MUST move the epic back to `work-items/epics/.md` and set `status: active` in the same lifecycle operation. A missing or duplicate `Epic:` target is invalid and must be reported distinctly. A work-item belongs to at most one epic. - **Vocabulary.** Express the epic and child closed-state with key `status` or `state` and a value drawn ONLY from `{closed, done, complete, completed, archived}` so the reused done-predicate matches; do NOT use the bug-registry `fixed`/`resolved` words for the done-line. - **Derived views.** Derive epic roll-up from physical child locations and regenerate `work-items/README.md` through the lifecycle owner. `work-items/index.md` may retain an `## Epics` compatibility snapshot but has no ongoing sync requirement. `work-items/` is gitignored, so this is local task-memory hygiene, not a committed change. Epic archive moves and physical-state reconciliation are the `$knowledge-archivist` hygiene lane; the epic lifecycle RULES (admit/link/roll-up/close) are owned by `$product-manager` and `$lead`. - **Lifecycle check.** No archival Stop control is registered. Use the lifecycle owner and documented state check to reject duplicate locations, missing terminal evidence, and active/archive disagreement. Whether the epic `## Goal` is met remains an explicit lead decision. ## Dependencies (work-item -> work-item) A work-item that needs another finished first declares `Depends-on: , ` — a bare, comma-separated line of work-item slugs — in its `status.md`. This is a standing, planned inter-work-item dependency edge. It is RELATED TO but NOT identical to the runtime `BLOCKED:*` gate verdicts: `BLOCKED:prerequisite` is the in-flight discovery of unplanned adjacent work, which is filed in the bug registry, and `BLOCKED:dependency` is an external blocker — `Depends-on` is neither; it is a declared edge between two planned work-items. - **Scope.** `Depends-on` targets are work-items ONLY, resolved by slug across THREE physical locations: `work-items/active/`, `work-items/archive/YYYY-MM/`, and admitted-not-yet-started `work-items/backlog/.md` files. `work-items/index.md` may summarize them but is compatibility-only. A backlog match is existence, not completion: an admitted item is never `done`, so a dependency on it stays open until the target item actually finishes. A slug that matches a bug/epic/decision but no work-item, or resolves in none of the three locations, is a **dangling** target — and dangling is NOT evidence of readiness: it is folded into `blocked-by` alongside genuinely open targets, never treated as satisfied. Bugs are not dependency targets. - **Derived (no stored cache).** `blocked-by(X)` = X's `Depends-on` targets that are not archived. The `ready-set` = active items whose every target uniquely resolves in `archive/` (or which have none). `/agents-status` and `/agents-resume` compute these through the physical lifecycle resolver; status and closure text alone never satisfy a dependency. - **Rule.** Record `Depends-on` when admitting or planning an item that needs prior work; do NOT start a blocked item's implementation while it has an open blocker. When a dependency closes, the dependent may become ready — `/agents-status` surfaces the newly-ready set. - **Integrity (authoring rule, not live detection).** Self-dependency is forbidden, and you must not author a dependency cycle (any `a -> ... -> a`). These are authoring-time obligations on `$lead`; the MVP does not run live cycle detection. `/agents-status` flags a dangling `Depends-on`. - **Residual (honest).** Dependency edges are governance-enforced only — no hook enforces them, so an item started while a dependency is still open is not structurally caught. ## Decisions (cross-cutting ADR registry) Durable, cross-cutting architecture decisions live in a flat registry `work-items/decisions/-.md` (the same flat list-item-frontmatter shape as `work-items/bugs/`), so a decision survives its originating work-item's archival instead of being buried in that item's `design.md`. - **Shape.** Frontmatter uses the bug-registry list-item style (`- key:` bullets, no `---` fences): `- id:`, `- status: proposed | accepted | dropped | superseded | reverted`, `- date: `, `- decided-by: `, `- context: `, `- supersedes: `, `- superseded-by: `. Body: `## Decision`, `## Rationale`, `## Consequences`, `## Alternatives rejected`. The decision `status` lifecycle is SELF-CONTAINED — independent of the work-item/epic done-predicate (a decision is never "closed" by it). The lifecycle owner structurally enforces those seven fields exactly once, non-empty, in the leading list block; `id` and `date` must match the filename. Optional list fields and indented continuations remain valid. Historical monthly archives retain legacy-read compatibility and immutable bytes. - **Authoring + acceptance gate.** `$architect` authors a cross-cutting or long-lived decision in `status: proposed`; a work-item's `design.md` REFERENCES it by id rather than duplicating it. Promotion `proposed -> accepted` happens only after the corresponding `$architecture-reviewer` gate passes. `proposed -> dropped` (with a one-line reason) retires a declined proposal. - **Citation contract (enforced both ways).** The registry id is a CONTRACT, not a courtesy: `$architect`'s gate requires every cross-cutting / long-lived decision in the claims section to carry a `work-items/decisions/` id, and `$architecture-reviewer` returns a blocking `REVISE` when such a decision is asserted in the design with no id. The trigger is NARROW — only decisions that outlive the work-item or constrain others; a local single-work-item decision stays inline in `design.md` so the registry does not flood. - **Supersede (two-way edge).** When decision B supersedes A, set B's `- supersedes: A` AND A's `- status: superseded` + `- superseded-by: B` in one step — a stored bidirectional link (mirroring the epic child<->parent join), not a registry-wide grep. `reverted` keeps a one-line reason. - **Ownership.** Lifecycle TRANSITIONS (proposed | accepted | dropped | superseded | reverted) are a SEMANTIC act owned by `$architect`/`$lead`; `$knowledge-archivist` does ONLY the non-semantic bookkeeping (writing the stored back-link field, reconciling physical locations, and verifying the generated read-model). `/agents-status` shows `proposed` decisions awaiting acceptance. - **Stale-proposed accountability.** `$lead` is accountable for resolving a `proposed` decision that `/agents-status` keeps surfacing — drive it to `accepted` (after the `$architecture-reviewer` gate) or `dropped` (with a one-line reason). Do not let a proposal idle indefinitely; listing it is visibility, not closure. - **Stale-proposed turn-end self-check (decidable, text-enforced).** At turn-end, if a current decision's lifecycle-validated leading block has both `- status: proposed` and `- date: ` strictly before today, name it and either route it to `$architecture-reviewer`, drop it with a reason, or state why it remains pending. A body quotation never counts. The first calendar day is the legitimate review window. SCOPE: decisions only; lessons use a different lifecycle. - **Residual (honest).** Current-record shape is structurally enforced by `scripts/mutate-work-item.py audit`; semantic staleness and supersession-link consistency are not. No hook decides when a proposal should advance or validates the two-way relation graph. A blocking stale-proposal Stop hook remains deferred pending evidence; do not add a parallel schema validator. ## Lessons (delivery lessons-learned registry) Lessons learned during delivery (a recurring miss, a wrong assumption, a process gap) live in a flat registry `work-items/lessons/-.md` (the same flat list-item-frontmatter shape as `work-items/bugs/`), so a lesson survives its originating work-item's archival instead of vanishing when that item closes. This is in-repo project task memory (gitignored data), NOT the operator's personal global memory; a lesson that generalizes beyond this project MAY ALSO be promoted to the spine or personal memory, but that is an additive, one-directional, separate manual act — the project-local entry stays the canonical project record. - **Shape.** Frontmatter uses the bug-registry list-item style (`- key:` bullets, no `---` fences): `- id:`, `- status: open | applied | dropped | archived`, `- source: `, `- category: process | technical | governance | tooling`. Body: `## Lesson` (one line), `## Context` (what happened), `## How to apply` (the concrete next action that would prevent a recurrence). The lesson `status` lifecycle is SELF-CONTAINED — independent of the work-item/epic done-predicate. - **Lifecycle.** `open` (captured, not yet acted on) -> `applied` (a named change shipped) -> `archived` (no longer relevant); plus `open` -> `dropped` (considered, not worth acting on — keep a one-line reason). A lesson stays in the registry as history, never deleted. - **Capture.** A lesson is captured by the closing role that ran the retrospective — the main conversation (as Lead) — or by `$qa-engineer`/a reviewer when they spot a recurring miss. The retrospective in `closure.md` is the natural capture point; each keep-worthy retro lesson becomes a registry entry, back-linked by id. - **Ownership.** Lifecycle TRANSITIONS (open | applied | dropped | archived) are a SEMANTIC act owned by the CLOSING role that captured the lesson (the main conversation as Lead), escalating to `$product-manager` when applying a lesson admits follow-up work; `$knowledge-archivist` does ONLY the non-semantic bookkeeping (physical/read-model reconciliation and the back-reference id). The archivist does NOT decide a lesson status transition. - **Stale-open accountability.** The main conversation (as Lead) is accountable for resolving an `open` lesson that keeps getting surfaced — drive it to `applied` or `dropped` (one-line reason). Listing it is visibility, not closure. - **Surfacing.** `/agents-status` lists `open` lessons (count + id + `## Lesson` first line). `$product-manager` consults open lessons when admitting similar work so the same mistake is not repeated. - **Residual (honest).** Registry hygiene is governance-enforced only — no hook scans `work-items/lessons/`, so an `open` lesson nobody applies is not structurally caught. ## Backlog (physical-root spec) Admitted-but-not-started items live as `work-items/backlog/.md`: the physical holding area between roadmap admission and active delivery, distinct from Active (in-flight) and Archived (done). The main conversation (as Lead) uses the lifecycle owner to move an item from Backlog to Active when work starts, and `/agents-status` surfaces the physical backlog set. `work-items/index.md` may summarize the backlog as a compatibility snapshot but is not its owner. ## Status board (work-items/README.md) `work-items/README.md` is the generated project **status board** and human recovery start — a short, structured "where does everything stand" read-model for the whole repository. It is DERIVED from the physical lifecycle roots and their owning status/closure artifacts; it summarizes them and points in, and MUST NOT copy per-item detail that can drift. `work-items/index.md` is an optional compatibility snapshot, never a state owner. - **Required shape** (adapt the names to the project, keep the shape): a **header** (what this is + snapshot date + current HEAD short SHA + who maintains + refresh cadence + the grounding rule: every status grounded in a cited commit/work-item, not memory); the operator-set **roadmap priority** ordering; **work areas** (the top-level project domains, 1-2 lines each); a main-thrust **milestone/phase table** (milestone | scope | status, with an explicit status marker per row drawn from FIVE STATES that are the actual contract — delivered/closed, in-progress, not-started, parked/operator-gated, blocker; the default RENDERING of those states is the glyph vocabulary ✅ 🔄 ⬜ ⏸ ⚠, and a plain-ASCII equivalent, e.g. `[done]`/`[wip]`/`[todo]`/`[parked]`/`[blocked]`, is permitted wherever glyph rendering is unavailable); **active sub-threads** (1 line each, with the gate or blocker named); **parallel arcs** (epics + other active items as an item | what | state table); the **immediate critical chain** (the next concrete dependency chain X -> Y -> Z); an **honest-scale** note (the largest remaining bodies of work, no over-claim); a REQUIRED one-line **`How to read`** legend naming whichever rendering (glyph or ASCII) is in use on this board; and a **Terms** section expanding every domain abbreviation used. - **Maintenance.** `$lead` owns the board's editorial framing (roadmap priority, milestone intent); the lifecycle owner regenerates it after lifecycle mutations, and `$knowledge-archivist` verifies the read-model in its post-wave Board-refresh control. The board is date + HEAD anchored; a snapshot that is stale between delivery waves is acceptable only because the header date makes the staleness visible. Ongoing `index.md` synchronization is not required. - **Registry reconciliation intake.** After task-memory governance changes, at milestone-wide cleanup, or when the operator asks to make all registries current, invoke `$knowledge-archivist` in `Registry Governance Reconciliation` mode. Consume the complete matrix: route every non-consistent semantic row to its documented owner, keep ambiguous ownership `BLOCKED`, and do not claim the registries current or close the parent item until the archivist's post-change structural AND semantic gates both return `PASS`. - **Discipline (rules, not suggestions).** Grounded, not remembered: every `delivered`/`done` claim cites a commit or work-item, verified against git and the tree. Honest scale: name the biggest remaining bodies plainly; forbid "almost done" while large milestones are un-started. No drift-prone duplication: summarize and point into physical roots and owning `status.md`/`closure.md` artifacts, do not copy per-item detail that will rot. Evidence-citation clean: where the project ships the evidence-honesty scanner, the board must pass it — a commit SHA written as commit ``, a digest as SHA-256 ``, each with its owning artifact named on the same line (bare SHAs fail). - **Relationship.** Read the board first for the big picture, resolve an item in the physical lifecycle roots, and read its owning `status.md` or `closure.md` for detail. The board complements `work-items/epics/` grouping; `index.md`, when retained, is only a compatibility snapshot. `work-items/` is gitignored local task memory, so neither generated view is a committed change. ## Operating pipeline The numbered stages below are a menu selected by the active template, not a mandatory sequence. Each route enters only at its selected stages. 0. `Roadmap / Intake` - Roles: `$product-manager`, `$product-analyst` as needed - Output: one roadmap decision package and, when needed, one factual product brief. 1. `Research` - Roles: `$analyst`, `$product-analyst` as needed - Operating-model alias: `researcher` - Output: one factual research artifact per role. 2. `Design` - Roles: `$architect`, `$ux-designer`, `$algorithm-scientist`, `$computational-scientist`, `$security-engineer`, `$performance-engineer`, `$reliability-engineer` as needed - Output: one design or specialist-constraint package per role. - Panel-eligible design (high-surface sweep / open architecture choice): convene the design-panel per `agents/contracts/design-panel.md` (`/agents-design-panel`) — N≥2 independently-framed lanes to `design-.md`, mandatory synthesis to `design.md`; lane outputs are never shippable alone. 3. `Plan` - Role: `$planner` - Output: one gated phase plan. 4. `Implement` - Roles: `$backend-engineer`, `$frontend-engineer` for web/React UI, `$graphics-engineer`, `$visualization-engineer`, `$geometry-engineer`, `$qt-ui-engineer` for Qt desktop UI, `$model-view-engineer`, `$data-engineer`, `$toolchain-engineer`, `$platform-engineer`, `$external-worker`, or another explicitly approved implementation specialist - Output: one implementation package for one approved phase. - Cross-cutting hygiene (invoke explicitly, outside the feature phase): `$knowledge-archivist` - If an archivist patch changes repository-wide control-plane semantics, route it through `$architecture-reviewer` before lead acceptance. - If the approved work spans multiple implementation phases or specialists, assign one explicit integration owner before QA. That owner assembles one coherent integrated artifact and checks cross-phase compatibility before verification begins. 5. `QA` - Roles: `$qa-engineer`, `$ui-test-engineer`, `$external-reviewer` as needed for eligible reviewer-side QA slots - Output: one verification package per verification role, including basic performance acceptance when relevant. 6. `Independent review` - Roles: `$architecture-reviewer`, `$performance-reviewer`, `$security-reviewer`, `$ux-reviewer`, `$accessibility-reviewer`, `$external-reviewer` as needed - Output: one review package per independent reviewer. - For each reviewer, choose the review strategy before delegating (see Review strategy rule below). 7. Human or CI gate - Output: explicit human approval, CI status, or documented external blocker. - For publication, `$lead` runs the publication-safety scan and `$knowledge-archivist` is the default publication-gate approver; the approver must be a different role than the role that accepted the artifact into the pipeline. 8. Optional batch-close consultant sweep - Role: `$consultant` - Output: one or more non-binding advisory memos, when explicitly requested by the lead or repo-local policy while `consultantMode` is enabled, that perform a final missed-change and residual-risk sweep and end with explicit reusable second prompts for continuing the work. Roadmap ownership stays upstream of the lead lane. The lead consumes approved roadmap or intake output; it does not own global prioritization or portfolio sequencing by default. `Quick-fix` admission is owned by shared governance. When selected, create its minimal pre-mutation recovery status and route `lead -> implementation -> qa -> lead`; if its predicate fails, re-classify by enriching the same work-item before continuing. After delivery, close and archive it immediately under the normal rule. ## Delegation contract Use the handoff template and response format in [subagent-contracts.md](../../agents/contracts/subagent-contracts.md). If any field is missing, tighten the task before delegating. - **Route-complete handoff**: a `quick-fix` handoff is its minimal pre-mutation `status.md`; recovery-tracked or multi-stage routes require current `brief.md` and full `status.md` before specialist dispatch. - **Evidence discipline required**: the handoff must include the template's `Evidence discipline` field with the four accepted evidence categories, `ASSUMPTION (UNVERIFIED)` fallback, and banned correctness-drivers; a handoff without it is incomplete. - **Tool selection recorded**: immediately before each subagent spawn, discover the current tool surface and fill `Allowed tools` with only the exact task-scoped identifiers selected for that run, or `none`; inherited availability does not widen that recorded selection. ## Delegation-first rule - If a task requires substantive research, design, planning, implementation, or review work and there is a matching specialist role, delegate it. - If evidence is weak or missing, route to a factual role before asking for broader judgment or tradeoff advice. - Use delegation itself as a noise filter: pass accepted artifacts instead of raw transcripts, keep interpretive roles downstream of evidence, and keep bounded corrections local to the current role. - Keep lead work limited to canonical brief maintenance, role selection, sequencing, gate decisions, and status synthesis. - Only do role-work directly when the task is trivial, purely coordinative, or there is no suitable specialist role. - If a worker handoff was interrupted and no artifact was produced, do not compensate by gathering code facts or drafting the missing artifact inline. Re-dispatch the same role with a narrower slice or route to `$analyst` / the appropriate factual role. - Maintain exactly one primary in-progress task. Side clarifications may refine it or temporarily interrupt it, but do not replace it unless the user explicitly reprioritizes. - If the primary task is a full-impact review or verification pass, keep that task open until a review artifact is produced; do not treat side clarification as completion or replacement of the review. - If the lead performs role-work by default, it has stopped acting as a lead and has become a generalist agent. ## Fact-first rule Routing unknowns to factual roles before interpretive ones, and citing accepted evidence for decisions, is the spine's rule; the lead's concrete routing on top: - Use `$analyst` for code and system facts, `$product-analyst` for user or product facts, and accepted metrics or constraints as the basis for roadmap or design decisions. - Require decision-making roles such as `$product-manager`, `$architect`, and specialist constraint roles to separate evidence, judgment, assumptions, and open questions explicitly. - Treat `$consultant` as optional independent judgment only after the strongest relevant factual slice is already available. - When both factual roles are needed, they can run in parallel since both are read-only. ## Review strategy rule Before delegating to any independent reviewer, choose one of two strategies: - **Claim-Verify**: risk is known and bounded. Builder includes claims list; reviewer verifies claims + finds uncovered surfaces. - **Adversarial**: risk is novel or externally exposed. Reviewer receives only the artifact and finds top 3 failu …(truncated)
