autopilot-implementer

autopilot-implementer is a skill for Claude Code, Codex from MatthewYe/autopilot-toolkit. It costs 45 tokens per session (2,348 once invoked), scanned A, original, no licence file.

An automated task implementer that reads a task contract, such as an AGENT-BRIEF or issue description, and carries out the work using test-driven development, or TDD, which means writing tests as part of the implementation process.

In plain words
What is it for?
It is for implementing contracted development tasks, handling errors during the work, and producing a structured implementation report.
Why use it?
It reduces the manual work of following a task brief, diagnosing errors, and documenting what was done.

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

autopilot-implementer 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 5d 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 ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
