implement

implement is a command for Claude Code from paruff/uFawkesAI. It costs 7 tokens per session (77 once invoked), scanned A, original, MIT.

An implementation command that follows the steps in plan.md, a document listing the work to perform. It implements one phase at a time, verifies each phase, updates the checklist, and asks for approval before continuing.

In plain words
What is it for?
Use it after a plan has been created to carry out the planned feature in stages with verification between phases.
Why use it?
It prevents implementation from drifting away from the agreed plan and creates checkpoints for reviewing progress.

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 8d 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

Read the feature's docs/ai-sdlc/<feature>/plan.md first. If missing, stop and instruct the user to run /plan. Implement one phase at a time. After each phase, run /verify gates. Update the plan checklist. Ask for checkpoint approval before proceeding.

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.
