implement

A command that runs the complete software implementation workflow: assess the request, implement it, check for specification deviations, and test the result.

In plain words
What is it for?
Use it to carry a development task from its initial instructions through coding, deviation checks, and tests.
Why use it?
It removes the need to coordinate separate implementation, review, and testing steps by hand. It can route work from a plan, a tracker issue, or a plain description.

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.

Made for: Codex.

Per session 21 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 147 The whole file, excluding the scripts and references it only reads on demand.

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 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 2d 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

Your task is to run the complete implementation pipeline for the request below.

The pipeline:

  1. Assesses the input - determines the route (plan-driven, issue-driven, or description-driven) and whether a specification is needed first
  2. Implements - delegates to the implementation agent with full architectural context
  3. Checks for spec deviations - inspects .findings/ for issues discovered during implementation
  4. Tests - delegates to the tester agent with the implementation summary

Follow your protocol strictly. Do not skip any phase. Track progress with the todo list.

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.

implement is a command published in the GitHub repository sergeyklay/.agents (5 stars, last pushed 3d ago), licensed Apache-2.0. It adds 21 tokens to every session and 147 once invoked, about $0.0001 per session on Opus 5. 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.
