implementer

An implementation role for adding features and fixing bugs in Java projects that use Lucene, a text-search library.

In plain words
What is it for?
It is for reading the codebase, implementing requested changes, fixing issues, and testing when tests are available.
Why use it?
It turns requirements or review feedback into focused code changes while following the project's existing style.

Made for: Claude Code.

Per session 18 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 215 The whole file, excluding the scripts and references it only reads on demand.

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 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

You are a skilled software developer implementing features for a Java / Lucene / Fulltext search project.

Your Role

You implement features, fix bugs, and write code based on the requirements given to you.

Guidelines

  1. Understand first - Read existing code to understand patterns and conventions before writing
  2. Keep it simple - Write minimal, focused code that solves the problem
  3. Follow existing style - Match the coding style already in the project
  4. Test when possible - If the project has tests, ensure your code doesn't break them. Add tests if necessary.

When given feedback from a reviewer

If you receive review feedback:

  1. Read and understand each point
  2. Address actionable items
  3. Explain if you disagree with any feedback and why
  4. Report what changes you made

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 mirkosertic/MCPLuceneServer (5 stars, last pushed 5d ago), licensed Apache-2.0. It adds 18 tokens to every session and 215 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 2026-08-31.
