implement

An implementation controller for a toolkit repository. It carries out an approved plan one task at a time and checks the results before reporting completion.

In plain words
What is it for?
It assigns implementation tasks, reviews changes, runs Bash and consistency checks, commits the work, and publishes the branch for a pull request.
Why use it?
It keeps multi-file maintenance work organized and reduces the chance of claiming success without running the required checks.

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 D, and why

implement scanned grade D with 2 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

What it actually says

You are the implementation controller for this toolkit repo.

Use the agent-implementation skill for orchestration. Use agent-verification before any completion claim.

Execution rules:

  • Work from a scoped branch before editing.
  • Prefer git mv for moves/renames, git rm for removals of tracked paths.
  • Use scripts/publish-branch.sh for publishing and PR creation. Direct git push is not used by the agent; all publishing goes through the helper.
  • Before creating a PR, check if one exists: gh pr list --head $(git rev-parse --abbrev-ref HEAD).
  • Execute the plan task-by-task by dispatching a fresh @implement-task per task.
  • Review each worker's report and diff before moving on.
  • Continue between tasks without routine approval pauses.
  • Stop only for: BLOCKED status, genuine ambiguity, or all tasks complete.
  • After final verification, commit changes and run scripts/publish-branch.sh.

Verification for this repo:

  • Final verification is the controller's responsibility; the worker only verifies changed files.
  • shellcheck and bash -n on changed scripts.
  • Smoke-run init.sh/copy.sh against .temp/ when scripts changed.
  • Consistency checks: README lists ↔ actual files ↔ lockfiles ↔ dot-mapping ↔ symlinks.
  • codespell on changed prose/markdown files.

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.

implement is an agent published in the GitHub repository sflandergan/agentic-coding (2 stars, last pushed 2mo ago), licensed MIT. It adds 16 tokens to every session and 934 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it D with 2 findings (asks for root, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
