implement

A command that follows the project’s implementation workflow to make planned code changes. It requires security checks and a recorded plan before editing files.

In plain words
What is it for?
Use it when carrying out an approved coding plan under the project’s implementation and security rules.
Why use it?
It keeps edits small and reversible, then requires a summary of the changes and supporting evidence.

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: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 95 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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 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.

What it actually says

/implement

Execute the canonical workflow: .agent/workflows/implement.md

Required reads before execution

  1. .agent/rules/security_guardrails.md — auto-enforced during implementation
  2. Active Work Log — must contain plan reference before proceeding

Execution

Follow every step in .agent/workflows/implement.md sequentially. Minimal and reversible edits only. After changes, provide diff summary and evidence. End response with ⚡ ACX.

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 KbWen/agentic-os (149 stars, last pushed 7d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 95 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 2026-08-30.
