debug-issue

A debugging workflow that tests possible explanations for a bug using runtime evidence and structured reasoning.

In plain words
What is it for?
It can use Sentry for production context and Firecrawl for researching fixes, then guide a multi-step investigation. API contract bugs and production monitoring have separate workflows.
Why use it?
It reduces guesswork by combining application evidence with step-by-step diagnosis and research into known fix patterns.

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.

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 yesterday.

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

/debug-issue

Hypothesis-driven debugging with runtime evidence — not guessing.

This command is a thin entry point. The full playbook lives in the debug-error skill, which integrates Sentry MCP for production context, Firecrawl for fix-pattern research, and Sequential Thinking for multi-step diagnosis.

Named /debug-issue (not /debug) to avoid colliding with Claude Code's bundled /debug skill.

Use /debug-issue to explicitly enter debug mode. Otherwise, say "debug this", "investigate the bug", or "why isn't this working" and the skill auto-fires.

Related: debug-fe-be-integration for API/contract bugs, debug-sentry-monitor for production triage.

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.

debug-issue is a command published in the GitHub repository kensaurus/cursor-kenji (9 stars, last pushed 3d ago), licensed MIT. It adds 20 tokens to every session and 193 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.
