bug-hunt

bug-hunt is a skill for Claude Code, Codex from dentiny/kon. It costs 43 tokens per session (996 once invoked), scanned A, original, MIT.

A read-only process for examining source code for possible bugs and suggesting ways to reproduce them. It does not edit project files or apply fixes.

In plain words
What is it for?
Use it with `/kon:hunt` to inspect code, review available history, propose reproduction SQL or commands, and suggest tests the user can run.
Why use it?
It helps investigate a suspected bug while preserving the repository for a later implementation step.

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

bug-hunt 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 121 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Bug Hunt

Owner: 🎸 Azusa Consumers: /kon:hunt

Core principles (always): follow skills/core-principles — first principles (don't hide the issue); simplest, most concise correct solution.

Static bug analysis from the codebase. Read-only — no file edits, no fixes, no mutating shell. Output includes best-effort repro SQL and test/command suggestions the user can run themselves.

When to use

User wants Command
Analyze a bug from code, suggest repro /kon:hunt
How does X work? /kon:ask
Fix a bug (repro + patch + review) /kon:debug

Read-only hard floor

Same as /kon:askzero repo writes.

Action Allowed?
Read / Glob / Grep source
Read-only git (log, diff, show, status)
Run read-only inspection commands (cat, python3 -c print-only)
Run tests that mutate repo / create caches ❌ (suggest command only)
Write / edit project files
Write session artifact hunt.md under ~/.kon/ ✅ (hook or orchestrator)
git commit / git push / checkout / reset

Analysis rules

  1. Evidence first — every claim cites path:line or command output you read
  2. Confidence labels — root cause: high | medium | low | unknown
  3. Unknown stays unknown — no invented behavior or file paths
  4. No fixes — optional "fix direction" bullets only; no patches or edits
  5. Best-effort repro — SQL/tests/commands are hypotheses; label assumptions

Output artifact

Follow templates/bug-report.md — user intake at top, analysis from Code trace down. Persist to sessions/<session-id>/hunt.md.

Repro guidelines (best-effort)

SQL

  • Only when the bug involves queries, schema, or data shape
  • Prefix with schema/table assumptions: -- assumes: users(id), orders(user_id)
  • Prefer minimal SELECT / EXPLAIN that would expose the bug
  • Mark: **Best-effort repro SQL** — verify table/column names against your schema

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.
