speckit.chore.implement

speckit.chore.implement is a command for Claude Code from arrrrny/zuraffa. It costs 14 tokens per session (1,830 once invoked), scanned A, original, MIT.

A command for carrying out a previously assessed chore, meaning a scoped maintenance task in a software project. It also records the work in an implementation report.

In plain words
What is it for?
Use it to implement a named chore and optionally isolate the work on its own Git branch or worktree, a separate working directory linked to a branch.
Why use it?
It keeps maintenance changes tied to an earlier assessment and leaves a written record of what was changed.

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

speckit.chore.implement 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.

How it starts

The opening of the file, as written. The whole thing — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Implement Chore

Apply the maintenance work that was scoped by __SPECKIT_COMMAND_CHORE_ASSESS__ and record the changes in an implement report at .specify/chores/<slug>/implement.md. This command is only valid after an assessment exists for the given slug. Pass --branch (or --worktree) to isolate the chore on its own git branch before editing, mirroring how __SPECKIT_COMMAND_SPECIFY__ isolates feature work.

User Input

$ARGUMENTS

The user input should identify the chore to implement. Accept any of:

  • slug=<chore-slug> or --slug <chore-slug> or just a bare slug-like token.
  • A path that contains the slug (e.g. .specify/chores/logo-swap/).
  • Branch isolation (optional): branch / --branch creates a chore branch (<prefix>/<slug>) first; worktree / --worktree creates a git worktree instead. See Optional — isolate the chore on a branch below.
  • Nothing — fall back to context (see below).

Slug Resolution

Resolve CHORE_SLUG in this order, stopping at the first match:

  1. Explicit user input — a slug passed in $ARGUMENTS (any of the forms above).
  2. Conversation context — if the current session has just run __SPECKIT_COMMAND_CHORE_ASSESS__, the slug it reported is the working slug. Reuse it without re-prompting. Confirm it by checking that .specify/chores/<slug>/assessment.md exists; if it does not, fall through.
  3. Single candidate on disk — list .specify/chores/*/assessment.md. If exactly one matching assessment.md is found, use the slug from its parent directory.
  4. Disambiguate:
    • Interactive mode: ask the user which chore to implement and list the candidates.
    • Automated mode: stop with an error listing the candidates. Do not guess.

Once resolved, set CHORE_SLUG and CHORE_DIR = .specify/chores/<CHORE_SLUG>, and briefly state in your reply which resolution path was used (explicit / from context / single candidate / asked).

Prerequisites

  • CHORE_DIR/assessment.md MUST exist. If it does not, stop and instruct the user to run __SPECKIT_COMMAND_CHORE_ASSESS__ first.
  • If CHORE_DIR/implement.md already exists, ask the user whether to overwrite it before continuing (interactive mode) or refuse (automated mode).
  • Read CHORE_DIR/assessment.md in full. Treat its Proposed Approach, Paths likely to change, Verification to run, Constitution Check, and Risks & Considerations sections as the contract for this command.

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.
