| name | code-audit-hardcore |
| description | Aggressive cleanup audit scoped to the user's specified changes plus tangibly-relevant surrounding code. Same blind audit-* specialists as code-audit, with a maximum-improvement posture — any code in the expanded review scope that can be cleaner WILL be made cleaner. Small fixes applied inline; big fixes (>5 files, schema, public API, redesigns) routed through `/plan-small` or `/plan-large`. Plan-overrides — when the audit reveals the original plan was wrong — route through `/plan-large` by default. Always improve over preserve. |
Code Audit (Hardcore)
Run code-audit's entire process (read code-audit/SKILL.md), with the deltas below. Don't restate the shared shape — the orchestrator follows code-audit, then applies these overrides.
What carries through from code-audit
Hardcore inherits all of code-audit's quality gates — the deltas change the posture and routing, not the gates:
- Verify clauses on every FIX, runnable. FIXes without one are downgraded to NOTEs.
- Agreement strength tracked through merge (
Strength: N/S).
- The seven-pattern verification gate: Verify-clause runnability, schema, library/dependency existence, API/function existence, import patterns, defensive guards, behavior-change visibility, standards conflicts, lazy-patch refusal.
- Lazy-patch refusal — silencing warnings, defensive guards for upstream bugs, renames-for-structural-issues, catch-and-log, fallbacks that mask invalid state. All downgraded to NOTE.
- Stop-out cases (mid-rebase / mid-merge / unresolved-conflict) — surface and stop, never apply through them.
- Working-tree scope discovery includes untracked files.
- Layered retry ladder for check-command failures (Stage 1 retry → Stage 2 fix → Stage 3 reconsider/revert → Stage 4 escalate).
- Big-output discipline.
- Hard guardrail:
code-audit is a skill, not a subagent. Do not call Agent(subagent_type="code-audit", …).
Deltas vs code-audit
| Aspect | code-audit | hardcore |
|---|
tier= default | auto | deep (run all five specialists) |
| Modes | report or cleanup | always cleanup — no report |
| Scope | the user-specified diff | core scope expanded to tangibly-relevant code (rule below) |
| Specialist user prompt | standard template | standard template + Posture: hardcore block (below) |
| Merge step | dedupe and verify | additionally promote NOTE→FIX when criteria met (below) |
| Routing axis | Scope: local | cross-cutting | plan-override | Size: small | big — replaces Scope (below) |
| Apply step | apply local FIXes only | classify each FIX small/big; apply small inline; route big through /plan-small or /plan-large |
| Plan-overrides | surface as QUESTION | route through /plan-large (hardcore acts) |
| Output | code-audit report template | hardcore template (below) |
Hardcore defaults to tier=deep because the expanded review scope and the always-improve posture both benefit from the research and architecture specialists, which standard omits.
When to use
- "Audit this and clean it up properly."
- "I'm reviewing this endpoint — if the API setup is wrong, fix the whole API setup."
- "Don't just check the diff, look at everything related and make it spotless."
- "The plan was wrong; figure out what we should do instead."
- After landing a feature where the diff was minimal but the surrounding code rotted around it.
For a strict diff-only review, use code-audit.
Args
scope=<files|diff|HEAD~N> — same shape as code-audit. The initial core scope; the skill expands from here per the rule below.tier=auto|light|standard|deep — passed through to code-audit's triage. Default deep. Pass tier=auto to let audit-triage right-size on the expanded review scope.
There is no mode= arg — hardcore always cleans up. For a report-only hardcore-style review, use code-audit mode=report and read it as a punch list.
The scope expansion rule
The user's specified changes are the core scope. They are a starting point, not a fence. Before the audit, identify the tangibly-relevant surrounding code and add it to the review:
- Files the core scope imports from where the import is load-bearing (not just a utility re-export).
- Setup / wiring code the core scope depends on: router config, middleware stack, DI container, schema definitions, base classes, shared types.
- Sibling files in the same module that share types, helpers, or conventions with the core scope.
- Tests for any of the above.
One hop out from the diff. Not callers (two hops). Not the whole repo. The user can rerun hardcore with explicit scope= to widen.
The union of the core scope and the tangibly-relevant set is the review scope. Present the expansion as a fact before fixing — the user should know what code the skill is touching, and they can interrupt to narrow. Default is forward; hardcore is aggressive, not chatty.
If the expansion is >15 files, group by module/area in the presentation instead of file-by-file — keeps the message scannable.
The always-improve rule then applies across the entire review scope:
When evaluating any line in the review scope, if there is a choice between leaving it as it is and improving it, choose to improve. Always. Conventions in the surrounding code are not a defense.
"Improvement" means the same dimensions the specialists already cover: cleaner naming, simpler control flow, fewer abstractions, no dead code, consistent layering, correct types, no duplication, proper error paths, modern API usage.
Specialist user prompt — Posture: hardcore
When fanning out, call the audit-* subagents directly — the same concrete Agent(subagent_type="audit-logic", …) etc. listed in code-audit/SKILL.md. Do NOT call Agent(subagent_type="code-audit", …) — code-audit is a skill, not a subagent. Append this block to the standard code-audit user prompt:
## Posture: hardcore — always improve
You are reviewing the user's diff PLUS the tangibly-relevant
surrounding code (setup, wiring, sibling files in the same module,
files the diff depends on). The full review scope is in the
"Files / diff in scope" section above.
When deciding between flagging an improvement to relevant
surrounding code and letting it go because "it's not in the strict
diff" — flag it. Always. The user's intent for this audit is
maximum cleanup of everything tangibly related to their changes.
Conventions in the surrounding code are not a defense. If the
existing pattern is bad, change it. If a routing setup is wrong,
fix the routing setup, not just the new endpoint. If a duplicated
utility exists next to the changes, replace the duplicate with a
call to the canonical version — and clean the canonical version
too if it needs it.
**Apply more, not faster.** A FIX that masks a symptom is a
regression even when it makes the build green. Hardcore's licence
is to improve aggressively — that licence is forfeit the moment
you take a lazy patch. When in doubt: surface the issue and let
the orchestrator route it through a plan skill, rather than
applying a band-aid.
You may flag improvements that exceed the scope of an inline
patch (rename a public API, redesign a module, change a schema).
Mark them clearly in your `Why:` — the orchestrator will route
them through a plan skill.
Promote NOTEs to FIXes whenever the note describes a concrete
improvement to code in scope. NOTE is for "interesting but no
action" only.
NOTE→FIX promotion criteria
After merge, walk every NOTE. A NOTE is promoted to FIX when all three are true:
- The NOTE identifies a specific
path:line and a named issue (not "this section could be cleaner").
- A concrete change can be expressed as a FIX with a runnable Verify clause.
- The change passes the lazy-patch check (addresses the underlying issue, not the symptom).
Vague NOTEs ("this abstraction could be better") stay as NOTEs. Concrete NOTEs ("the if (x) return x chain on lines 42–47 duplicates the lookup in getUser — extract a helper") get promoted with a real Fix and Verify.
Small-vs-big classifier
After merge and promotion, each FIX is big if any of these are true:
- Touches >5 files.
- Changes a database schema or migration.
- Changes a public API (exported function signature, HTTP route shape, CLI argument).
- Refactors a module's external surface (rename, split, merge).
- Requires user-facing behavior change.
- The specialist's
Fix: is "redesign X" / "extract Y into a new module" rather than a concrete patch.
- The FIX implies the original plan's approach was wrong (plan-override). These always go through
/plan-large, regardless of how localized the patch itself would be.
Otherwise: small.
When in doubt, classify big. Plans are cheap; bad refactors are not.
Routing
Small FIXes — apply inline. After each batch, run the project check command with the layered retry ladder (inherited from code-audit's cleanup mode):
- Stage 1 (Level 0 retry): Re-run; clears transient failures.
- Stage 2 (Level 0 fix): Fix the immediate breakage caused by the FIXes.
- Stage 3 (Level 1 reconsider): Which specific FIX caused the breakage? Try reverting that FIX rather than fixing forward. In hardcore, aggressive batches mean more false-positive risk; reverting and re-classifying as NOTE is often the right call.
- Stage 4 (Level 3 escalate): Stop, surface the failing diff and which FIXes were applied.
Stage 3 matters more in hardcore than in code-audit because hardcore applies more FIXes per batch — so the probability that one is wrong is higher, and "revert the suspect FIX" is the safety valve that prevents an aggressive batch from forcing the user into manual cleanup.
Big FIXes — cluster related ones by module/theme. For each cluster, derive a kebab-case slug from the cluster's theme (≤4 words: e.g. routing-cleanup, error-handling-refactor, schema-naming), then invoke:
/plan-small "<cluster description>" slug=<derived-slug>
…or /plan-large when the cluster spans modules or PRs. Plan-override clusters always go through /plan-large regardless of size — they need the schema-first treatment and the architectural-decisions structure that the small-plan template doesn't have.
The plan skill's own slug-collision logic (-2, -3) handles duplicates. Hardcore stops at "plan written" and surfaces the plan path. Implementation belongs to the plan skill and its corresponding /implement-plan invocation.
Behavior-changing FIXes are surfaced in the output even when applied as small fixes. Apply more, not faster — never silent.

Rules
- Scope starts at the user's changes; expand to tangibly-relevant surrounding code; do not expand to the whole repo. One hop out — load-bearing imports, setup/wiring, sibling files, tests. Not callers, not config, not two-hop.
- Always improve over preserve. Conventions are not a defense. Existing patterns are observations, not defaults.
- Apply more, not faster. A lazy patch is doubly damaging in hardcore. Refuse it; route through a plan instead.
- Promote NOTEs to FIXes when all three criteria are met: specific path:line, concrete change with runnable Verify, passes the lazy-patch check. Vague NOTEs stay NOTEs.
- Big fixes go through plan skills. Hardcore does not implement them inline. Public API changes are always big.
- Plan-overrides route through
/plan-large, not surfaced as QUESTIONs. Hardcore acts on plan-overrides; that's the philosophical line between code-audit and hardcore.
- Behavior-changing FIXes are surfaced in output even when applied. Never silent.
- Routing axis is
Size: small | big, not code-audit's Scope: local | cross-cutting | plan-override. The two skills decide different things; don't carry both axes.
- Verify clauses on every FIX are mandatory (inherited from code-audit). FIXes without a runnable Verify are downgraded to NOTEs.
- Specialists run as
audit-* subagents with their built-in anti-bias contract. The hardcore posture is added per-call in the user prompt; do not duplicate it inside the agent's system prompt.
- The check command must pass after every batch of small fixes — same layered ladder as code-audit cleanup mode. Stage 3 (reconsider/revert the suspect FIX) matters more in hardcore than elsewhere; use it.
- Stop-out cases (mid-rebase / mid-merge / unresolved-conflict) — surface and stop; do not apply through them. Inherited from code-audit.
- Hardcore stops at "plan written" for big fixes. It does not silently invoke
/implement-plan after writing plans. The user reviews the plans, then decides.
- Big-output discipline. Heavy command output goes to
/tmp/hawk-code-audit-hardcore-<step>.log, narrow with rg -n '<pattern>' /tmp/hawk-code-audit-hardcore-<step>.log | head -50. See code-audit/SKILL.md and the README for the full recipe.
