Swe Workflow

SWE Workflow

The idiomatic software-engineer workflow: clarify the idea → spec it → slice it → triage it → ship it. Five stages, each with a dedicated skill and a durable artifact that feeds the next.

File-based end to end — each step hands the next a markdown artifact: CONTEXT.md/ADRs → FEATURES.md → PRD → issues → task_plan.md → progress.md. The files are the interface between steps; nothing lives only in the agent's head.

Parallel concern: /triage

/triage sits beside the chain, not inside it — a small state machine over the issue tracker (needs-info / ready-for-agent / ready-for-human / wontfix). Required for issues filed outside the chain (user bug reports, external contributions, ad-hoc feature requests); redundant for chain-created issues, since /to-prd and /to-issues auto-label ready-for-agent at creation.

See REFERENCE.md for the full state machine and per-state outputs.

Design philosophy

This is a chain of small skills, not a framework. Three principles guard against drifting into framework opacity:

1. Own the process. "Process" here means deciding what goes into context at each stage. Every skill in the chain is a markdown file you can read, edit, swap, or skip — there is no opaque orchestrator.
2. Every artifact is observable. PRDs, issues, AGENT-BRIEFs, task_plan.md, findings.md, progress.md — all human-readable markdown, all cat-able at any point.
3. Ephemeral state is intentional. Per-issue worktrees and planning files die when the PR ships. Deliberate defense against spec/plan drift accumulating into a "ball of mud" over time.

Operating maxim (Matt Pocock, after surveying ~2000 AI coding course participants on framework dissatisfaction): "a good framework hands a lot of control over to the user and is easy to observe." If a proposed addition reduces either, reject it — even if it's borrowed from a framework that looks useful.

Concrete commitments derived from these principles:

• Instructions-only, no scripts. Deterministic operations are documented as instructions the agent runs, not wrapped in scripts. Every script reintroduced would move the chain toward the opacity Matt's surveyed users rejected.
• Transparent markdown all the way down. Seven chain stages plus /triage as a parallel concern — every link is a markdown skill or documented procedure you can read, edit, or replace without touching code. None of them opaque. The direct test of the operating maxim above.

Engineering-side, by design. The mattpocock toolchain assumes features come from product thinking (user needs, business goals) that lives outside this skill ecosystem. Stage 2 (/to-features) is the deliberate seam: features get enumerated here (read from CONTEXT.md + ADRs), but discovered elsewhere — in user interviews, product strategy, sales conversations, whatever your team uses. This toolchain has no opinion on that.

See REFERENCE.md for the comparison with spec-kit / BMAD / GSD.

Where to enter the chain

Don't always start at stage 1 — jump to where the chain actually breaks.

When is it done?

The mirror image of "Where to enter the chain" — four levels of "done", four signals:

A feature's completion is mechanical: walk from the PRD to its child issues (via the parent reference /to-issues writes), confirm all closed, then strike through the FEATURES.md line:

- [x] ~~user-can-reset-password~~ — ~~A user can reset...~~ (shipped: #42, #43, #44)

Software projects rarely "complete" — features keep getting added. If you need a hard milestone, layer on your tracker's mechanism (gh milestone, Linear cycles, release tags) and define "project complete" as that milestone closing. See REFERENCE.md for per-tracker completion queries.

Stages 5-7: worktree + planning-with-files

The skill is instructions-only — there are no scripts. The agent performs each step manually, adapting to the team's issue tracker.

Bootstrap

1. Pick the tracker. See Tracker selection below.

2. Fetch the issue per trackers/<name>.md — extract title, body, labels, AGENT-BRIEF.

3. Derive paths:

   • slug = title → lowercase → non-alphanumerics replaced with - → truncate to 40 chars
   • branch = issue-<id>-<slug> (Linear's TEAM-123 passes through literally)
   • worktree = ../<repo>-issue-<id>/

4. Create the worktree: git worktree add ../<repo>-issue-<id> -b issue-<id>-<slug>

5. cd in and seed three planning files:

   File	Contents
   task_plan.md	Goal = title; Phases = AC checkboxes. Structured fields only (hook re-injection risk).
   findings.md	Raw issue body + AGENT-BRIEF pasted verbatim. Safe sink for external content.
   progress.md	Initial session log entry with bootstrap timestamp.

6. Invoke /planning-with-files:plan (Stage 5) with this prompt:

   /planning-with-files:plan Interview me about this issue, then write task_plan.md to implement it. The plan must use /tdd (tests first: red → green → refactor) for writing code and tests, and apply /karpathy-guidelines (surgical, simple changes) for code quality — and it must name both skills explicitly in task_plan.md so they're used when the plan is executed.

   The interview refines the seeds — sharpens phases, surfaces key questions, captures decisions to make. task_plan.md is the core artifact Stage 6 reads; findings.md holds the raw issue body. The prompt's last clause is load-bearing: telling the planner to name /tdd and /karpathy-guidelines inside task_plan.md is what carries the methodology into Stage 6 — plan-goal re-reads the plan, sees the skills called out per phase, and applies them instead of being re-told.

7. Invoke /planning-with-files:plan-goal to execute (Stage 6) — reads task_plan.md, drives each phase as a goal via Claude Code's goal command; outer loop runs phases; /tdd is the inner loop for code-producing phases. Since the Stage 5 prompt already named /tdd and /andrej-karpathy-skills:karpathy-guidelines, the plan calls for them — plan-goal carries them out: test-first, surgical changes, simplicity first, no speculative abstractions, surfaced assumptions.

8. Close out (Stage 7) — open the PR with the body drawn from progress.md highlights (the session log is the narrative; don't rewrite it). After it merges, tear down the worktree and branch.

Tracker selection

Priority order:

1. $SWE_WORKFLOW_TRACKER env var (explicit override)
2. tracker=<name> line in .swe-workflow.conf at the repo root
3. Auto-detect from project signals:
   • .scratch/ directory → local-markdown (mattpocock's .scratch/<feature>/ convention)
   • github remote + gh installed → github
   • gitlab remote + glab installed → gitlab
   • .linear/ directory → linear
   • $MULTICA_WORKSPACE_ID set → multica (no project-level signal — Multica config is user-level)
4. Still ambiguous → ask the user.

Per-tracker fetch commands and conventions: trackers/<name>.md. To add a new tracker, write a new doc following the same shape — nothing else changes.

Inner loop: /tdd for code-producing phases

/planning-with-files:plan-goal is the outer loop (phases, state, errors); /tdd is the inner loop (one failing test → one minimal fix). For each phase in task_plan.md that produces testable code:

Mark phase in_progress  →  /tdd (red → green → refactor)  →  log to progress.md  →  Mark phase complete

Not every phase needs /tdd — exploration, config tweaks, and infra changes skip it. See REFERENCE.md for the full nuances (multiple cycles per phase, decision/error capture, when /tdd's own planning step duplicates vs. complements the issue-level plan).

Teardown (after PR merges)

From the main checkout (NOT inside the worktree):

# Verify no uncommitted changes
git -C ../<repo>-issue-<id> status --porcelain

# Remove worktree
git worktree remove ../<repo>-issue-<id>

# Delete branch only if merged into the default branch
default_branch=$(git symbolic-ref refs/remotes/origin/HEAD | sed 's@^refs/remotes/origin/@@')
git branch --merged "$default_branch" \
  | grep -qE "^[[:space:]]*\*?[[:space:]]*issue-<id>-<slug>$" \
  && git branch -d "issue-<id>-<slug>"

Critical handoff rules

1. PRD uses the glossary from stage 1. If to-prd introduces terms that conflict with CONTEXT.md, loop back to /grill-with-docs.
2. Issues are tracer bullets, not horizontal layers. Each is a thin vertical slice (schema → API → UI → tests). "Backend issue" + "frontend issue" is a smell — re-slice.
3. Only ready-for-agent issues enter execution. /to-issues auto-applies the label on chain-created issues; /triage applies it to external issues (user reports, etc.). Either way, stage 5 reads from the label, not the source.
4. One issue = one worktree = one task_plan.md. Filesystem isolation for parallel AFK agents. No exceptions.
5. Strike through, don't delete. When a feature ships, strike it through in FEATURES.md with a shipped reference — never delete. Preserves institutional memory; prevents quiet scope drift.

Don't double-track

Security boundary

planning-with-files re-injects task_plan.md into context on every tool call. Any text in task_plan.md is an amplified prompt-injection target.

• Raw issue bodies, fetched docs, web content → findings.md only.
• task_plan.md gets only structured fields the executor wrote (Goal, Phases from AC, Decisions, Errors).

The bootstrap procedure (Stages 5-7) enforces this split.

When to skip this skill

• Single-file edits (no spec, no plan needed)
• Bug fixes where the AGENT-BRIEF is one paragraph — just do it, skip stage 5 bootstrap
• Exploration / prototypes — use the prototype skill instead
