execute

A step-by-step workflow for implementing feature tasks that are tracked across multiple sessions. TDD, or test-driven development, means writing a failing test first, then implementing the code that makes it pass.

In plain words
What is it for?
Use it to build features split into dependent tasks, with automated tests, pre-commit checks, code review, pull requests, and tracker updates.
Why use it?
It selects tasks whose prerequisites are complete and keeps implementation, reviews, commits, pull requests, and issue status connected. This reduces manual tracking during larger feature work.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

execute scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Coco Execute Skill

This skill delegates to the /coco:execute command, which implements the full 15-step TDD execution loop with PR workflow, AI code review, and issue tracker bridge sync.

When to Use

  • Implementing a feature that has been imported into the coco tracker as an epic
  • Executing tasks from a specs/{feature}/tasks.md that has been converted to tracked tasks
  • Any multi-session work where dependency tracking matters

Alternatives

  • For single-issue hotfixes or quick changes, use the hotfix skill instead
  • For autonomous execution until epic completion, use /coco:loop

Execution

Run the /coco:execute command. It handles:

  1. Pre-execution gate (tracker + issue tracker verification)
  2. Dependency-aware task selection via coco-tracker ready
  3. Issue branch creation (if pr.enabled)
  4. Issue tracker bridge (start: "In Progress")
  5. TDD implementation (RED -> GREEN -> verify)
  6. Pre-commit validation (UI change detection)
  7. Commit with issue key traceability
  8. PR creation with issue ID (if pr.enabled)
  9. AI code review via code-reviewer agent
  10. Review-fix loop (max 3 iterations)
  11. PR merge (if pr.enabled)
  12. Tracker task close
  13. Issue tracker bridge (complete: "Done" at PR merge)
  14. Acceptance criteria verification
  15. Next task check (loop or report completion)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

execute is a skill published in the GitHub repository skullninja/coco-workflow (7 stars, last pushed 2d ago), licensed MIT. It adds 39 tokens to every session and 366 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
