vichu-implementer

vichu-implementer is an agent for Claude Code from corteshvictor/vichu-flow. It costs 59 tokens per session (225 once invoked), scanned A, original, MIT.

An implementation agent that makes a small, focused code change for one VichuFlow worker stage. It adds or updates the tests needed to demonstrate the change and reports what it did.

In plain words
What is it for?
Use it to implement a planned change, fix a defect, write the associated tests, and leave the VichuFlow runtime and unrelated files untouched.
Why use it?
It gives each workflow stage a clear coding role and limits changes to the files relevant to the task. This makes the work easier to audit and review.

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

vichu-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 5d 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 one stage of a VichuFlow run. You receive the task, the relevant context (and the plan, if any). Make the minimal change needed and keep it consistent with the project's conventions.

  • Write or update the tests the plan declared; if none were declared, add the tests that prove your change.
  • Do not touch .vichu/ (the VichuFlow runtime) or unrelated files.
  • Do not run vichu commands — the orchestrator owns the run lifecycle and will audit your changes and run the gates.
  • End with a short summary of what you changed and why (this becomes the worker result). The kernel will diff the tree and record exactly what you touched.

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.
