Swarm Flow

swarm-flow — the SDLC router

Thin by design: this skill decides which phase runs; all expertise lives in the phase skills. Load the chosen skill before proceeding.

Read this before working, not after. In a SwarmVault-registered project this skill is the entry point for any substantive request — including ones that sound like a direct order ("add login", "fix the schema", "build the dashboard"). Route first, then work: two tool calls of routing prevent building the wrong thing, code with no ticket, or two agents editing the same file. If you are about to write feature code and cannot name the ticket it belongs to, you skipped this step — come back and route.

Deciding you can skip the flow is itself a flow decision. For genuinely trivial or one-off asks (a typo, a question about existing code, a shell one-liner) say so in one clause and proceed — but say it, so the user can disagree. Never skip silently.

The resume promise: routing needs ONLY vault state — flow-state, ticket statuses, the question queue, memory. "Continue project X" works from a cold session; never ask the user what happened last time, and never require a previous transcript. A session that died mid-work still lands correctly: stale claims surface via TTL, half-done phases surface via their artifacts.

Route

1. Resolve the project (swarmvault.py context .; doctor if that fails).
2. Read 30 Plans/<P>/flow-state.md — but artifacts on disk win over stale state; correct the note with a logged line if they disagree.
3. Decide by the first matching row:

4. Announce phase + evidence in one line ("SRS validated, 3 open tickets in M2 → implementing"), then proceed.

Design lanes (recorded in flow-state as design-lane: standard|deep)

Asked once, when the design phase opens; the answer routes the whole phase. If it is already recorded, don't re-ask — resume that lane.

• standard (default, recommended) — swarm-design. The agent proposes the architecture, the user validates it. Right for most projects.
• deep — swarm-design-deep. Developer-driven: the user commits to each approach before anything is written, down to pseudocode, algorithms and test vectors. Slower and more expensive on purpose. Offer it when the user says they want to own or fully understand the system, asks for pseudocode/algorithm-level planning, or names "developer mode".

They replace each other — never run both. Switching lanes mid-phase keeps closed work.

Modes (recorded in flow-state as mode: gated|auto)

• gated — stop at every phase/milestone boundary for the user's stakeholder verification before continuing.
• auto — chain phases without stopping; the swarm-review sweep is the milestone gate; append non-blocking questions to the question queue; stop only when truly blocked (credentials, contradictory requirements, destructive/irreversible actions).

The mode is asked once at SRS validation (swarm-spec) and the user may change it anytime.

Classify the ask before routing a change

Once an SRS is validated, a request is one of six things, and misreading it is how specs rot. The test: does any accepted criterion of an existing FR change?

The label isn't the deliverable; the impact set is — which FRs, ADRs, open tickets, and tests this touches. State the read in one line before acting ("amendment to FR-11, impacts ADR-004 and 2 open tickets"). In gated mode, wait for a nod on new requirement and withdrawal only. Log it as a CR-NNN entry in the requirements tracker either way.

Rules

• Scheduled continuation: if context shows a ⏳ Scheduled continuation (or plan-continue show returns one), you were resumed to push a usage-limited project forward — just route to the current phase and continue. When all milestones are done (or the plan's --scope is reached), clear it: plan-continue clear --project <P>. See swarm-orchestrate for scheduling one.
• Safe-state compaction: on a long task, at a resumable boundary you may checkpoint (record a safe-state note), compact/clear context to save tokens, and continue — the vault is your state. Quality first: never compact mid-work if continuity is carrying the task. Details in swarm-orchestrate.
• Never silently skip a user-validated gate; user-requested phase jumps are allowed with a one-line warning about what's being skipped.
• On phase completion, the finishing skill updates flow-state (phase:, mode:, description: compact status); offer — don't force — the next phase in gated mode.
• Monorepos: the nearest .swarmvault marker wins.
