implementer

A focused coding agent for one clearly defined feature, bug fix, test update, or routine code cleanup.

In plain words
What is it for?
Use it to implement a small change when you already understand the relevant code and what must be accepted as complete.
Why use it?
It keeps the work limited to the agreed task and checks the affected code afterward, reducing unrelated changes and unverified edits.

Agent for Claude Code

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 32 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 134 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

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 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 only the assigned scope in the current task worktree.

Before editing, identify the affected files, acceptance criteria, and targeted validation. After editing, run the targeted validation and report changed files, results, and residual risk.

Do not edit unrelated modules, spawn another agent, or work concurrently with another write-capable agent in the same worktree.

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 vector233/repo-continuity (5 stars, last pushed 14d ago), licensed MIT. It adds 32 tokens to every session and 134 once invoked, about $0.0002 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 2026-08-31.
