testdino-mcp: Skill for Claude Code

.claude/skills/fix/SKILL.md

fix is a skill for Claude Code from testdino-hq/testdino-mcp. It costs 23 tokens per session (692 once invoked), scanned A, original, MIT.

A step-by-step workflow for fixing a tracked software bug, from confirming the problem through testing and documentation.

In plain words
What is it for?
Use it to investigate bugs recorded in ISSUES.md, trace failures through tool code and requests, make a focused fix, run relevant tests, and record the result.
Why use it?
It helps prevent guessing, symptom-only fixes, and forgotten issue updates by requiring the cause and the full change to be checked.

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

fix 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 9d 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.

Fix the bug: $ARGUMENTS

Workflow

0. Check Tracking + Memory

  • Check auto-memory for prior lessons matching this bug type
  • Read ISSUES.md — find the relevant tracked issue by ID or description
  • If the issue isn't tracked yet, add it to ISSUES.md first (assign next ISS-NNN ID)
  • Update issue status to IN PROGRESS

1. Verify the Issue Exists

  • Read the code at the reported location
  • Confirm the bug is real, not a false alarm
  • If already fixed or no longer applies: update ISSUES.md status to FIXED and stop

2. Root-Cause Analysis

  1. Read the code — understand what it does, not what you think it does
  2. Trace the data flow — for tool issues: schema → handler → endpoint → request → response
  3. Never stop at the first failure — ask "why did THIS fail?" and trace backward
  4. Check Known Patterns & Pitfalls in CLAUDE.md — is this a known pattern?

3. Implement the Fix

  • Fix the root cause — not the symptom
  • Minimal change — don't refactor surrounding code
  • Follow the project's conventions (CLAUDE.md)
  • If the fix changes tool behavior or params, note what docs need updating

4. Test

  1. Can an existing test be updated to cover the fix? Update it
  2. Does the fix change observable behavior no test covers? Add a regression test
  3. The test must fail before the fix and pass after — verify this mentally or actually

5. Verify

Run the quality gate immediately after the fix:

npm run typecheck && npm run lint && npm run test -- --passWithNoTests

All must pass. git diff — confirm only intentional changes.

6. Document

This step is not optional. The fix is incomplete until:

  1. ISSUES.md is updated with:
    • Status: FIXED with date
    • Root cause (file:line — one sentence)
    • Fix description
    • Files changed
    • Tests added/updated
  2. docs/TOOLS.md updated if the fix changes tool behavior
  3. CLAUDE.md Known Patterns & Pitfalls updated if the pattern is generalizable
  4. Auto-memory lesson written if anything went wrong during the fix process

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.

fix is a skill published in the GitHub repository testdino-hq/testdino-mcp (9 stars, last pushed 1mo ago), licensed MIT. It adds 23 tokens to every session and 692 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.
