Implement Skill

Quick Ref: Execute single issue end-to-end. Output: code changes + commit + closed issue.

YOU MUST EXECUTE THIS WORKFLOW. Do not just describe it.

Execute a single issue from start to finish.

CLI dependencies: bd (issue tracking), ao (ratchet gates). Both optional — see

skills/shared/SKILL.md

for fallback table. If bd is unavailable, use the issue description directly and track progress via TaskList instead of beads.

Execution Steps

Given

/implement <issue-id-or-description>

Step 0: Pre-Flight Checks (Resume + Gates)

For resume protocol details, read
skills/implement/references/resume-protocol.md
.

For ratchet gate checks and pre-mortem gate details, read
skills/implement/references/gate-checks.md
.

Step 1: Get Issue Details

If beads issue ID provided (e.g.,

gt-123

bash

bd show <issue-id> 2>/dev/null

If plain description provided: Use that as the task description.

If no argument: Check for ready work:

bash

bd ready 2>/dev/null | head -3

Step 2: Claim the Issue

bash

bd update <issue-id> --status in_progress 2>/dev/null

Step 3: Gather Context

USE THE TASK TOOL to explore relevant code:

Tool: Task
Parameters:
  subagent_type: "Explore"
  description: "Gather context for: <issue title>"
  prompt: |
    Find code relevant to: <issue description>

    1. Search for related files (Glob)
    2. Search for relevant keywords (Grep)
    3. Read key files to understand current implementation
    4. Identify where changes need to be made

    Return:
    - Files to modify (paths)
    - Current implementation summary
    - Suggested approach
    - Any risks or concerns

Step 4: Implement the Change

Based on the context gathered:

Edit existing files using the Edit tool (preferred)
Write new files only if necessary using the Write tool
Follow existing patterns in the codebase
Keep changes minimal - don't over-engineer

Step 5: Verify the Change

Success Criteria (all must pass):

All existing tests pass (no new failures introduced)
New code compiles/parses without errors
No new linter warnings (if linter available)
Change achieves the stated goal

Check for test files and run them:

bash

# Find tests
ls *test* tests/ test/ __tests__/ 2>/dev/null | head -5

# Run tests (adapt to project type)
# Python: pytest
# Go: go test ./...
# Node: npm test
# Rust: cargo test

If tests exist: All tests must pass. Any failure = verification failed.

If no tests exist: Manual verification required:

Syntax check passes (file compiles/parses)
Imports resolve correctly
Can reproduce expected behavior manually
Edge cases identified during implementation are handled

If verification fails: Do NOT proceed to Step 5a. Fix the issue first.

Step 5a: Verification Gate (MANDATORY)

THE IRON LAW: NO COMPLETION CLAIMS WITHOUT FRESH VERIFICATION EVIDENCE

Before reporting success, you MUST:

IDENTIFY - What command proves this claim works?
RUN - Execute the FULL command (fresh, not cached output)
READ - Check full output AND exit code
VERIFY - Does output actually confirm the claim?
ONLY THEN - Make the completion claim

Forbidden phrases without fresh verification evidence:

"should work", "probably fixed", "seems to be working"
"Great!", "Perfect!", "Done!" (without output proof)
"I just ran it" (must run it AGAIN, fresh)

Rationalization Table

Excuse	Reality
"Too simple to verify"	Simple code breaks. Verification takes 10 seconds.
"I just ran it"	Run it AGAIN. Fresh output only.
"Tests passed earlier"	Run them NOW. State changes.
"It's obvious it works"	Nothing is obvious. Evidence or silence.
"The edit looks correct"	Looking != working. Run the code.

Store checkpoint:

bash

bd update <issue-id> --append-notes "CHECKPOINT: Step 5a verification passed at $(date -Iseconds)" 2>/dev/null

Step 6: Commit the Change

If the change is complete and verified:

bash

git add <modified-files>
git commit -m "<descriptive message>

Implements: <issue-id>"

Step 7: Close the Issue

bash

bd update <issue-id> --status closed 2>/dev/null

Step 7a: Record Implementation in Ratchet Chain

After successful issue closure, record in ratchet:

bash

# Check if ao CLI is available
if command -v ao &>/dev/null; then
  # Get the commit hash as output artifact
  COMMIT_HASH=$(git rev-parse HEAD 2>/dev/null || echo "")
  CHANGED_FILES=$(git diff --name-only HEAD~1 2>/dev/null | tr '\n' ',' | sed 's/,$//')

  if [ -n "$COMMIT_HASH" ]; then
    # Record successful implementation
    ao ratchet record implement \
      --output "$COMMIT_HASH" \
      --files "$CHANGED_FILES" \
      --issue "<issue-id>" \
      2>&1 | tee -a .agents/ratchet.log

    if [ $? -eq 0 ]; then
      echo "Ratchet: Implementation recorded (commit: ${COMMIT_HASH:0:8})"
    else
      echo "Ratchet: Failed to record - chain.jsonl may need repair"
    fi
  else
    echo "Ratchet: No commit found - skipping record"
  fi
else
  echo "Ratchet: ao CLI not available - implementation NOT recorded"
  echo "  Run manually: ao ratchet record implement --output <commit>"
fi

On failure/blocker: Record the blocker in ratchet:

bash

if command -v ao &>/dev/null; then
  ao ratchet record implement \
    --status blocked \
    --reason "<blocker description>" \
    2>/dev/null
fi

Fallback: If ao is not available, the issue is still closed via bd but won't be tracked in the ratchet chain. The skill continues normally.

Step 7b: Post-Implementation Ratchet Record

After implementation is complete:

bash

if command -v ao &>/dev/null; then
  ao ratchet record implement --output "<issue-id>" 2>/dev/null || true
fi

Tell user: "Implementation complete. Run /vibe to validate before pushing."

Step 8: Report to User

Tell the user:

What was changed (files modified)
How it was verified (with actual command output)
Issue status (closed)
Any follow-up needed
Ratchet status (implementation recorded or skipped)

Output completion marker:

<promise>DONE</promise>

If blocked or incomplete:

<promise>BLOCKED</promise>
Reason: <why blocked>

<promise>PARTIAL</promise>
Remaining: <what's left>

Key Rules

Explore first - understand before changing
Edit, don't rewrite - prefer Edit tool over Write tool
Follow patterns - match existing code style
Verify changes - run tests or sanity checks
Commit with context - reference the issue ID
Close the issue - update status when done

Without Beads

If bd CLI not available:

Skip the claim/close status updates
Use the description as the task
Still commit with descriptive message
Report completion to user

Distributed Mode: Agent Mail Coordination

Distributed mode enhances /implement with real-time coordination via MCP Agent Mail when

--mode=distributed

--agent-mail

, or

$OLYMPUS_DEMIGOD_ID

is set.
