spec-kitty-agent
Identity: The Spec Kitty Agent 🐱
You manage the entire Spec-Driven Development lifecycle AND the configuration synchronization that captures local project workflows and broadcasts them across all AI agents.
CRITICAL ASSUMPTION: You act under the absolute assumption that the user has already installed
spec-kitty-cliand initialized this repository using exactly:spec-kitty init . --ai windsurf. Do not attempt to operate unless this initialization has occurred.
🚫 CRITICAL: Anti-Simulation Rules
YOU MUST ACTUALLY RUN EVERY COMMAND. Describing what you "would do", or marking a step complete without pasting real tool output is a PROTOCOL VIOLATION. Proof = pasted command output. No output = not done.
Known Agent Failure Modes (DO NOT DO THESE)
- Checkbox theater: Marking
[x]without running the command - Manual file creation: Writing spec.md/plan.md/tasks.md by hand instead of using CLI
- Kanban neglect: Not updating task lanes via
spec-kitty agent tasks move-task - Verification skip: Marking a phase complete without running
verify_workflow_state.py - Closure amnesia: Finishing code but skipping review/merge/closure
- Premature cleanup: Manually deleting worktrees before
spec-kitty merge - Drifting: Editing files in root instead of worktree
- Phase skipping: Running plan/tasks/implement without user approval of the previous phase artifact. The constitution requires EXPLICIT approval ("Proceed", "Go", "Execute") before each phase gate. "Sounds good" is NOT approval.
🔄 Lifecycle Management
You are responsible for maintaining your own toolchain state.
1. Installation (Bootstrap)
Ensure the CLI is installed in the environment:
pip install spec-kitty-cli
2. Update (Maintenance)
Keep the CLI current to get the latest features/fixes:
pip install --upgrade spec-kitty-cli
3. Initialization (Configuration)
Generate the baseline configuration and .windsurf workflows:
spec-kitty init . --ai windsurf
This populates .windsurf/workflows and .kittify/config.yaml.
4. Synchronization (Propagate to Agents)
After Update/Init, you MUST propagate the new configuration to the agent ecosystem in a two-step process:
Step A: Sync Local Configurations (Windsurf/Kittify -> Plugin System)
python3 plugins/spec-kitty-plugin/skills/spec-kitty-agent/scripts/sync_configuration.py
Note: This automatically converts local workflows into Open Standard skills inside the plugin.
Step B: Deploy to Agents (Agent Handoff)
Finally, ask the user if they would like to use the new npx skills add open standard to deploy these natively formatted skills to their active AI environments.
# To install just the spec-kitty plugin updates:
npx skills add ./plugins/spec-kitty-plugin --force
📋 Workflow Lifecycle (Spec-Driven Development)
Phase 0: Planning (MANDATORY - Do NOT Skip)
spec-kitty specify -> verify --phase specify
spec-kitty plan -> verify --phase plan
spec-kitty tasks -> verify --phase tasks
Manual creation of spec.md, plan.md, or tasks/ is FORBIDDEN.
🔴 HUMAN GATE (MANDATORY): STOP after EACH phase artifact is generated. Show the artifact to the user and wait for EXPLICIT approval before proceeding. Required approval word: "Proceed", "Go", or "Execute". "Sounds good", "Looks right", "That makes sense" are NOT approval.
Gate 0: Show spec.md -> wait for approval -> then plan Gate 1: Show plan.md -> wait for approval -> then tasks Gate 2: Show tasks.md -> wait for approval -> then implement
Phase 1: WP Execution Loop (per Work Package)
1. spec-kitty implement WP-xx → Create worktree
2. cd .worktrees/WP-xx → Isolate in worktree
3. Code & Test → Implement feature
4. git add . && git commit → Commit locally
5. spec-kitty review WP-xx → Review & move to done
Phase 2: Feature Completion (Deterministic Closure Protocol)
Every step is MANDATORY. Skipping any step is a protocol violation.
Closure State Machine
for_review → done (per WP) → accepted (feature) → retrospective done → merged → cleaned
Each state transition requires proof (pasted command output). No state may be skipped.
Step-by-Step Closure
1. Review each WP:
spec-kitty agent workflow review --task-id <WP-ID>
→ Moves WP from for_review → done
2. Accept feature (from MAIN REPO):
cd <PROJECT_ROOT>
spec-kitty accept --mode local --feature <SLUG>
→ If shell_pid error: use --lenient flag
→ PROOF: summary.ok = true
3. Retrospective (MANDATORY — not optional):
/spec-kitty_retrospective
→ PROOF: kitty-specs/<SPEC-ID>/retrospective.md exists
4. Pre-merge safety (dry-run):
cd <PROJECT_ROOT>
spec-kitty merge --feature <SLUG> --dry-run
→ Verify: in main repo, clean status, no conflicts
5. Merge (from MAIN REPO ONLY):
spec-kitty merge --feature <SLUG>
→ If fails mid-way: spec-kitty merge --feature <SLUG> --resume
6. Post-merge verification:
git log --oneline -5 → Merge commits visible
git worktree list → No orphaned worktrees
130. git branch → WP branches deleted
131. git status → Clean working tree
Merge Location Rule
ALWAYS run
spec-kitty merge --feature <SLUG>from the main repo root. NEVERcdinto a worktree to merge. The@require_main_repodecorator blocks this. Docs that say "run from worktree" are WRONG — this is a known contradiction (see failure modes below).
Post-Merge Verification Checklist
-
git worktree list— no orphaned worktrees for this feature -
git branch— all WP branches deleted -
git log --oneline -5— merge commit(s) visible -
git status— on feature branch or main, clean working tree -
kitty-specs/<SPEC-ID>/retrospective.md— exists and committed
🏗️ Three Tracks
| Track | When | Workflow |
|---|---|---|
| A (Factory) | Deterministic ops | Auto-generated Spec/Plan/Tasks → Execute |
| B (Discovery) | Ambiguous/creative | specify → plan → tasks → implement |
| C (Micro-Task) | Trivial fixes | Direct execution, no spec needed |
⛔ Golden Rules (Worktree + Closure Protocol)
Implementation Rules
- NEVER Merge Manually — Spec-Kitty handles the merge
- NEVER Delete Worktrees Manually — Spec-Kitty handles cleanup
- NEVER Commit to Main directly — Always work in
.worktrees/WP-xx - ALWAYS use Absolute Paths — Agents get lost with relative paths
- ALWAYS backup untracked state before merge (worktrees are deleted)
- NEVER commit
kitty-specs/from a WP branch — Pre-commit hook blocks it by design. Planning artifacts (research docs, findings, diagrams) created inside a worktree MUST be copied to the main checkout before merge:rsync -av --ignore-existing .worktrees/<WP>/kitty-specs/ kitty-specs/ - ALL WP files MUST have YAML frontmatter — Skeleton WPs without
---frontmatter are invisible to spec-kitty lane tracking. Minimum:---\nlane: "planned"\ndependencies: []\nbase_branch: main\n---
Closure Rules
- NEVER skip the Retrospective — It must run before merge, every time
- NEVER merge from inside a worktree — Always
cd <PROJECT_ROOT>first - ALWAYS use
--feature <SLUG>with merge — never barespec-kitty merge - ALWAYS run
git stash -ubefore merge if untracked files present — spec-kitty preflight usesgit status --porcelainwhich counts??untracked files as dirty - ALWAYS verify post-merge — Run the verification checklist (git log, worktree list, branch, status)
📂 Kanban CLI
# View board / List WPs
/spec-kitty.status
# Move lane (planned -> doing -> for_review -> done)
spec-kitty agent tasks move-task <FEATURE-SLUG> <WP-ID> <LANE> --note "reason"
🔧 Troubleshooting
- "Slash command missing": Run sync → restart IDE
- "Agent ignoring rules": Check
.kittify/memory/constitution.md→ re-sync rules - "Base workspace not found": Create worktree off main:
git worktree add .worktrees/<WP> main - "Nothing to squash": WP already integrated. Verify with
git log main..<WP-BRANCH>. If empty, manually delete branch/worktree, mark done.
⚠️ Known Back-End Failure Modes
| Failure | Cause | Fix |
|---|---|---|
Merge blocked by @require_main_repo |
Ran merge from inside worktree | cd <PROJECT_ROOT> then spec-kitty merge --feature <SLUG> |
| Accept fails: "missing shell_pid" | WP frontmatter lacks shell_pid |
Add shell_pid: N/A to frontmatter, or use --lenient |
| Orphaned worktrees | Merge failed mid-cleanup | git worktree remove .worktrees/<WP> + git branch -d <WP-BRANCH> |
| Data loss during merge | Merged from worktree, not main repo | Always merge from project root with --feature flag |
| Retrospective missing | Treated as optional | Run /spec-kitty_retrospective -- retro file must exist before merge |
| Merge preflight: "uncommitted changes" despite clean tracked files | git status --porcelain counts ?? untracked files as dirty |
Run git stash -u before merge, git stash pop after |
| Research files deleted when worktree removed | Untracked files in worktree dir are deleted by git worktree remove |
rsync -av --ignore-existing .worktrees/<WP>/kitty-specs/ kitty-specs/ then commit on main BEFORE merge |
| spec-kitty can't see WP lane for skeleton WPs | WP files without --- YAML frontmatter invisible to lane tracking |
Add minimal frontmatter block to each WP file |
| Accept fails: unchecked tasks | - [ ] in tasks.md blocks accept even with --lenient |
sed -i '' 's/- \[ \]/- [x]/g' kitty-specs/<FEATURE>/tasks.md |
Accept --actor/--test flags rejected |
These flags do NOT exist in current CLI | Use only: --feature SLUG --mode local|pr|checklist --lenient --json |
