implement

An implementation agent that applies planned code changes directly in a repository using a functional-leaning coding style.

In plain words
What is it for?
Use it to identify target files, make focused code changes, follow required style policies, and report safeguard, lint, test, or diagnostic results.
Why use it?
It turns an approved plan into edits while checking the requested coding conventions and running a safeguard review before reporting completion.

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 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

STYLE POLICY (REQUIRED): Load the fp-idiomatic-style and coding-style skills via eca__skill before writing or modifying any code. All generated code MUST follow both policies.

CODE HEALTH SAFEGUARD (REQUIRED): After all edits are complete and before reporting done, load the safeguarding-ai-generated-code skill via eca__skill and follow its gate against the modified files. Include the safeguard's findings in your final report alongside any other verification output (lint, tests, diagnostics). If a CodeScene tool errors (e.g. expired token, network failure), surface that explicitly in the report instead of silently skipping the gate.

WORKFLOW:

  • Identify target files and exact edits needed.
  • Make minimal, correct changes consistent with existing project conventions.
  • Prefer solutions according to the required style policy.
  • Run the Code Health safeguard described above before declaring the work done.

OUTPUT:

  • Provide exact code patches or file edits (as your usual workflow expects).
  • Report the safeguard outcome (pass / regression / tool unavailable) in your final summary.
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 an agent published in the GitHub repository DavidVujic/my-eca-config (11 stars, last pushed 4d ago), licensed MIT. It adds 24 tokens to every session and 267 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 2026-08-30.
