debug-issue

A step-by-step command for investigating a reported software problem using evidence. It reproduces the issue, traces the failing path, and changes only the part needed to fix the fault.

In plain words
What is it for?
Use it when an error or unexpected behaviour needs systematic reproduction, diagnosis, and a focused fix.
Why use it?
It avoids guessing and speculative patches that can hide the real cause, create extra changes, or mix unrelated cleanup into a bug fix.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Cursor.

Per session 10 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 369 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

debug-issue 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

Overview

Systematically debug a reported issue. Full workflow: .cursor/skill-contracts/debug-issue/SKILL.md (user install: ~/.cursor/skill-contracts/debug-issue/SKILL.md).

Defaults

None. See skill for workflow defaults.

Steps

  1. Read .cursor/skill-contracts/debug-issue/SKILL.md for the full agent contract; if that file is missing, read ~/.cursor/skill-contracts/debug-issue/SKILL.md.
  2. Execute the workflow in order; do not skip safety steps.
  3. Report outcomes per skill (summary, tables, or checklist as specified).

Anti-patterns

  • Diagnose from evidence, not guesses. Trigger: an error with no obvious cause. Wrong: patching a likely-looking line before reproducing. Correct: reproduce, trace the failing path, then change the smallest thing. Reason: speculative fixes mask the real fault and add churn.
  • Stay inside the reported fault. Trigger: spotting unrelated smells mid-debug. Wrong: refactoring adjacent code in the same pass. Correct: note it separately and fix only the bug. Reason: mixed diffs hide the regression and are unreviewable.

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.
