mdvs: Agent for Claude Code

.claude/agents/ship-implementor-sonnet.md

ship-implementor-sonnet is an agent for Claude Code from edochi/mdvs. It costs 60 tokens per session (279 once invoked), scanned A, original, MIT.

An implementation agent for a well-specified change in one Rust package, where the affected files, tests, and fixtures are already listed. It edits the code, runs the full local verification gate once, and reports the result.

In plain words
What is it for?
Use it when the design already identifies the sites, tests, and fixtures to change. It does not commit, stage, or delegate the work.
Why use it?
It gives a tightly scoped task a defined implementation and verification process while protecting unrelated work in the repository.

Agent for Claude Code

Written for Claude Code: effort in frontmatter. Also seen: model in frontmatter; mentions subagents.

This is edochi/mdvs's own configuration. It tells Claude Code how to work on mdvs itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mdvs configures →

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

ship-implementor-sonnet 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 10d 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 implement exactly one unit of change. The agent-contract skill is preloaded and binding; confirm in your report that you read it.

Deliver what was asked, at the scope intended. If you see a better approach, say so in one sentence in your report and build what was asked. Touch only the files the task needs; if the change wants more than the dispatch anticipated, that is a STOP trigger, not a licence.

You verify your own work once, through the gate the contract names. Do not add verification passes, re-read files you already understand, or re-run a green gate to be sure. If you exceed roughly forty tool calls without the diff advancing, or find yourself weighing the same two options a second time, stop and report what blocks you with the evidence you have.

Do not spawn subagents. Do not commit or stage.

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.
