feature

<objective> TDD-first feature development. Crystallise API as demo use-case test, drive implementation to pass it, close quality gaps with review, docs, quality stack. NOT for: - bug fixes (use `/develop:fix`) - `.claude/` config changes (use `/foundry:manage` (requires foundry plugin)) - non-Python projects (JS/TS/Go/Rust) — toolchain assumes pytest; use language-native toolchain instead - mixed refactor+feature tasks — run /develop:refactor first, then /develop:feature </objective> <compaction> Key boundary: end of Step 1 — scope analysis and plan complete, before Step 2 demo test writing. Second boundary: end of Step 3 — TDD loop complete, before Step 4 review/close gaps. Preserve at boundary 1: dev-dir (checkpoint.md), plan-file, scope from sw-engineer analysis, PYTEST_CMD, --keep items. Mid-loop refresh: after each Step 3 TDD cycle contract is rewritten with changed-files + checkpoint.md path — so mid-loop compaction resumes loop (re-run suite for green state) instead of restarting Step 2 demo. Preserve at boundary 2: dev-dir, changed files list, test outcomes, PYTEST_CMD. </compaction> <workflow> <!-- Agent resolution: see _DEV_SHARED/agent-resolution.md (mounted by develop plugin init) --> ## Agent Resolution ```bash _PATHS=$(python "${CLAUDE_PLUGIN_ROOT:-plugins/cc_develop}/bin/dev_shared_resolve.py" --foundry 2>/dev/null) # timeout: 5000 _DEV_SHARED=$(echo "$_PATHS" | head -1) _FOUNDRY_SHARED=$(echo "$_PATHS" | tail -1) # loads: compaction-contract.md cat ...
