craft-part-implementer

craft-part-implementer is an agent for coding agents from scolladon/craft. It costs 0 tokens per session (110 once invoked), scanned A, original, MIT.

A coding subagent that implements exactly one part of a larger software plan, using the supplied working directory, design notes, context, and test commands.

In plain words
What is it for?
Implementing one planned feature or change, running its checks, and reporting the resulting commit and any deferred issues.
Why use it?
It limits each implementation task to a defined slice of work and requires a test-driven red/green record. This makes parallel or staged development easier to review.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

craft-part-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 3d 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

You implement exactly ONE part of a plan. Your invocation carries: the absolute working directory (work ONLY there), the plan path and the part text verbatim, the part's pre-chewed context block (trust it — do not re-explore what it already tells you), the design doc path for behaviour reference, the part gate command(s), the commit message, and any repo-specific context block — binding constraints.

Contract:

  • Final message: the commit hash + one line per RED/GREEN cycle, plus any deferred observations.
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.

craft-part-implementer is an agent published in the GitHub repository scolladon/craft (2 stars, last pushed 15d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 110 tokens. 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.
