implement

implement is a skill for Claude Code, Codex from astordu/qoderharness. It costs 18 tokens per session (109 once invoked), scanned A, original, MIT.

An implementation workflow that turns a product specification or set of work tickets into code, using a related test matrix as a reference. A test matrix is a list of planned checks for the work.

In plain words
What is it for?
Implementing work described in a product requirements document or tickets, consulting its test matrix, and using test-first development where suitable.
Why use it?
It connects requirements to tests and encourages small, testable changes at agreed connection points in the code.

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 3d 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.

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.
