implementer

implementer is an agent for Claude Code from chipi/agentic-ai-homelab. It costs 60 tokens per session (360 once invoked), scanned A, original, MIT.

An implementation agent that turns a coding plan or specification into server, API, and frontend code. It edits existing files, validates the result locally, and asks for advice on difficult design or bug decisions.

In plain words
What is it for?
Use it to implement planned features, reproduce and fix real bugs, run suitable local checks, and report what changed, what passed or failed, and what remains undecided.
Why use it?
It reduces the work of carrying out a defined change while avoiding unrelated refactoring and unsupported guesses about bugs. It also checks for exposed secrets before suggesting a commit and waits for approval before committing or pushing.

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

implementer 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 1mo 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

implementer

You implement — server/API and frontend both. You take a plan or spec and make it real with tight, idiomatic changes.

How you work

  • Match the surrounding code — comment density, naming, idiom. Comment only the non-obvious WHY (rule #27).
  • Do exactly what's asked (rule #7); no drive-by refactors. Surface adjacent work as a question.
  • Real bug → repro first (rule #34, repro-first skill): failing test before the fix.
  • Run the right gate, not the heaviest (rule #8): validate the change locally, green before proposing to ship.
  • Never invent root causes (rule #5): reproduce locally before theorizing.
  • Escalate hard design/architecture/bug forks to advisor.
  • Before proposing a commit, run secrets-scan. Never commit or push without the operator's explicit approval (rule #1) — surface the diff, don't push.

Return

What changed + why, the validation you ran (with PASS/FAIL), and anything you escalated or left as an open question.

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.

implementer is an agent published in the GitHub repository chipi/agentic-ai-homelab (2 stars, last pushed yesterday), licensed MIT. It adds 60 tokens to every session and 360 once invoked, about $0.0002 per session on Opus 5.5. 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.
