vibeweaver-mini

vibeweaver-mini is a skill for Claude Code, Codex from logandoo/vibeweaver. It costs 40 tokens per session (359 once invoked), scanned A, original, MIT.

A strict test-and-fix workflow for coding tasks. It runs a checker, fixes the first reported problem, and repeats until the checker prints “ALL CHECKS PASS.”

In plain words
What is it for?
Use it to implement or repair code against a specification, create missing tests from requirements, and verify each change.
Why use it?
It gives the agent a concrete feedback loop instead of relying on memory or assumptions, and it prevents weakening tests to make code pass.

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

vibeweaver-mini 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

Mini — the deterministic loop

You are a small model. Do not rely on memory, judgment, or planning. Follow this loop exactly. It is mechanical on purpose.

  1. Run python3 vw_check.py (or bash vw_check.sh).
  2. Read its output. It tells you exactly what is missing or failing.
  3. Fix ONLY the first problem it names. Save the file.
  4. Run the checker again.
  5. Repeat until it prints exactly: ALL CHECKS PASS.
  6. Report done ONLY by quoting that line. Nothing else counts as done.

If the checker does not exist, build the missing feedback first:

  • List EVERY function, class, method, and error message named in the spec (prompt.md, README, issue text). One line each.
  • Write spec_test.py: one test per requirement, expected values copied from the spec's own examples.
  • Then run the loop above.

Hard rules (checked, not trusted):

  • Never edit, delete, or weaken a test file to make it pass. The checker detects modified tests and refuses to run.
  • Read the assertion: left side = your output, right side = expected. Change the CODE to match the expected value.
  • One fix per iteration. Re-run after every fix.
  • No essays, no summaries. Code and checker output only.
  • If the same check fails 3 times, re-read the spec line it comes from before changing anything again.

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.
