implement-slice

A command that carries out one planned slice of work listed in TASK_STATE.md. It then runs tests and reviews the resulting code before reporting the outcomes.

In plain words
What is it for?
Use it to implement one specific task slice, verify it with tests, and receive a review without automatically starting the next slice.
Why use it?
It prevents work from moving ahead when an earlier required slice is unfinished. It also separates implementation, testing, and review for each piece of a task.

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

implement-slice 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 yesterday.

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.

Origin

This is a copy

100% identical to implement-slice — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Execute slice $ARGUMENTS.

  1. Read TASK_STATE.md, locate the slice.
  2. If not found, or if prior required slices are unchecked → STOP.
  3. Spawn implementer subagent with the slice ID.
  4. Then spawn test-runner to verify.
  5. If tests pass, spawn reviewer on the diff.
  6. Report all three outputs (implementer summary, test result, review verdict).

Do NOT proceed to the next slice. Each slice gets its own invocation.

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.
