bughunt

bughunt is a command for Claude Code from robzilla1738/roberts-skills. It costs 32 tokens per session (682 once invoked), scanned A, original, MIT.

A report-only codebase review that searches for hidden bugs, user pain points, and inefficient areas, then ranks reproducible findings.

In plain words
What is it for?
Use it to inspect the whole repository, a path, a module, staged changes, or differences from the merge base.
Why use it?
It helps developers find problems that ordinary review or existing tests may miss without changing the code.

Command for Claude Code

Written for Claude Code: argument-hint in frontmatter.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

bughunt 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 2mo 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

Run a bug hunt against: $ARGUMENTS

Load and follow the bughunt skill at ${CLAUDE_PLUGIN_ROOT}/skills/bughunt/SKILL.md exactly. Parse $ARGUMENTS for:

  • Scope — diff (vs the merge base) · staged (git-staged changes) · a path like src/api · a named module · empty = whole repo.
  • Depth — quick (a handful of cells, fast) · deep (full fan-out; the default for a whole-repo hunt).
  • ci — non-interactive mode: don't ask the user anything, run merge with --require-verified --require-coverage --strict --fail-on critical-high, and surface the exit code (0 no new Critical/High / 1 new Critical/High / 3 malformed or IO error). Use --fail-on any only when Medium/Low should return 2.

Then run the loop:

  1. Recon & pre-pass — detect platform and map trust boundaries. When python3 is available, run the deterministic pre-pass for ranked targets: python3 ${CLAUDE_PLUGIN_ROOT}/skills/bughunt/scripts/bughunt.py census, hotspots, signals, deps (see tooling.md). On a large/unfamiliar repo, confirm scope first (skip the prompt under ci).
  2. Fan out — build the (lens × hotspot) grid and dispatch hunters via the capability ladder in orchestration.md: the shipped Workflow script if available, else parallel Tasks, else a sequential walk. Hunters return findings as JSON.
  3. Verify (mandatory) — a skeptic pass tries to refute every candidate before it reaches the report (verification.md).
  4. Merge & triage — pipe findings through bughunt.py merge (fingerprint, dedupe, cross-validate, suppress, baseline-diff) and score with the triage rubrics. Under ci, include --require-verified --require-coverage --strict --fail-on critical-high.
  5. Report — bughunt.py render emits the ranked markdown (+ HTML + SARIF) into .bughunt/.

This is report-only: surface and prove bugs, do not edit code unless I ask. If python3 is unavailable, follow the markdown fallback (no scripts; findings stay in markdown). If $ARGUMENTS is empty, ask what to hunt (whole repo, a module, or a diff) and which depth.

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.
