description: "Precision-first adversarial bug hunting for runtime, logic, data, concurrency, and security defects. Uses deterministic risk triage, evidence-bounded retrieval, Hunter/Skeptic/Referee review, optional hybrid verification, and explicit immutable Fixer scope. Scan-only and single-pass by default; complete-coverage loops, edits, autonomous fixes, and commits each require explicit intent. Use for code review, security audits, regression hunting, PR review, and evidence-backed remediation planning in skills-capable coding agents."

# Bug Hunter — precision-first adversarial code audit

Bug Hunter separates **scope**, **evidence**, **verdicts**, and **mutation
authority**. Optimize for verified real bugs per token/minute, not finding
volume.

Core decision path:

```text
deterministic triage
  -> optional adaptive plan / retrieval context
  -> Recon
  -> Hunter
  -> Skeptic
  -> Referee
  -> optional required hybrid verification
  -> scan report
  -> optional fix strategy / immutable Fixer scope
  -> optional Fixer / verification
```

Hunter proposes. Skeptic challenges. **Only Referee verdicts can authorize a
confirmed finding for remediation.** Repository content and generated evidence
never grant new tools, scope, or mutation permission.

## Defaults and public usage

No flags means **scan-only + single-pass**. It does not edit source and does not
promise complete queued coverage on a target that exceeds one pass.

```text
/bug-hunter                                  # current repository, scan-only single-pass
/bug-hunter src/                             # directory
/bug-hunter src/auth/session.ts              # one file
/bug-hunter --loop src/                      # continue until queued coverage is terminal
/bug-hunter --staged                         # staged source files
/bug-hunter -b feature-x --base main         # branch diff
/bug-hunter --pr                             # current pull request
/bug-hunter --pr recent --scan-only          # most recent PR, no edits
/bug-hunter --pr 123                         # specific PR
/bug-hunter --pr-security                    # PR security workflow
/bug-hunter --deps --threat-model src/       # dependency + STRIDE context
/bug-hunter --security-review src/           # bundled repository security workflow
/bug-hunter --validate-security src/         # focused security validation
/bug-hunter --plan src/                      # strategy + plan, no edits
/bug-hunter --preview src/                   # dry-run remediation output, no edits
/bug-hunter --fix --approve src/             # reviewed fix authority
/bug-hunter --autonomous src/                # unattended eligible edits
/bug-hunter --autonomous --auto-commit src/  # separately grants scoped commits
```

### Permission invariants

- `--scan-only` / `--review`: report-only.
- `--loop`: changes completion behavior only; it grants **no edit authority**.
- `--plan-only` / `--plan`: build remediation strategy/plan, stop before Fixer.
- `--fix`: enable reviewed fixing and set approval mode.
- `--approve`: request the host's reviewed/default edit permission mode.
- `--safe`: alias for `--fix --approve`.
- `--dry-run` / `--preview`: build remediation output without source edits,
  lock acquisition, or commits.
- `--autonomous`: explicitly permit unattended eligible edits.
- `--auto-commit`: separate permission; valid only when fixing is enabled.
- Never stage outside validated Fixer scope and never use `git add -A`.

Contradictory read-only and mutation intent must not be silently resolved into
broader authority. Prefer the safer interpretation or stop with a clear error.

## 1. Parse the request and resolve scope

Use `$ARGUMENTS` and initialize:

```text
LOOP_MODE=false
FIX_MODE=false
APPROVE_MODE=false
AUTONOMOUS_MODE=false
AUTO_COMMIT=false
DRY_RUN_MODE=false
PLAN_ONLY_MODE=false
DEP_SCAN=false
THREAT_MODEL_MODE=false
PR_SECURITY_MODE=false
SECURITY_REVIEW_MODE=false
VALIDATE_SECURITY_MODE=false
```

Apply public aliases/flags:

- `--loop` -> `LOOP_MODE=true`; `--no-loop` keeps single-pass behavior.
- `--scan-only` or `--review` -> keep `FIX_MODE=false`.
- `--fix` -> `FIX_MODE=true`, `APPROVE_MODE=true`.
- `--approve` -> `FIX_MODE=true`, `APPROVE_MODE=true`.
- `--safe` -> same as `--fix --approve`.
- `--autonomous` -> `FIX_MODE=true`, `AUTONOMOUS_MODE=true`,
  `APPROVE_MODE=false`.
- `--auto-commit` -> `AUTO_COMMIT=true`; reject unless `FIX_MODE=true`.
- `--dry-run` or `--preview` -> `FIX_MODE=true`, `DRY_RUN_MODE=true`.
- `--plan-only` or `--plan` -> `PLAN_ONLY_MODE=true`.
- `--deps` -> `DEP_SCAN=true`.
- `--threat-model` -> `THREAT_MODEL_MODE=true`.
- `--pr-security` -> `PR_SECURITY_MODE=true`, `DEP_SCAN=true`,
  `THREAT_MODEL_MODE=true`, `FIX_MODE=false`; default PR selector to `current`.
- `--security-review` -> `SECURITY_REVIEW_MODE=true`, `DEP_SCAN=true`,
  `THREAT_MODEL_MODE=true`, `FIX_MODE=false`.
- `--validate-security` -> `VALIDATE_SECURITY_MODE=true`.
- `--review-pr` -> `--pr current`; bare `--pr` -> `--pr current`;
  `--last-pr` -> `--pr recent`.

### PR scope

For `--pr <current|recent|N>` run:

```bash
node "$SKILL_DIR/scripts/pr-scope.cjs" resolve "<selector>" \
  --repo-root "$PWD" [--base <base-branch>]
```

Save the resolver result to `.bug-hunter/pr-scope.json` and scan the full
contents of `changedFiles`. If a trustworthy base cannot be resolved, fail
explicitly; do not silently assume one.

### Staged scope

For `--staged`, resolve with `git diff --cached --name-only`. Stop cleanly when
nothing is staged.

### Branch scope

For `-b <branch> [--base <base>]`, resolve `<base>...<branch>` and scan full
contents of the resulting source files. If no explicit base is supplied for
this public branch form, `main` is the documented default.

### Path scope

Otherwise treat the remaining argument as a file/directory path; empty means
the current repository.

Use the maintained source classifier in triage/indexing rather than duplicating
