Placeholder skill directory required by skill-eval's runeval tool signature. This benchmark runs configurations=['withoutskill'] only — we are measuring raw model tiers, not a skill — so this file's content is never mounted or read by a subject session.
Skill Claude CodeCodex
Implements a coding task from a written spec with Done-When acceptance items. Use when given a spec to implement: stub the interface, implement it, then write tests that validate the Done-When items and any important behavior beyond them.
Skill Claude CodeCodex
Implements a coding task from a written spec with Done-When acceptance items. Use when given a spec to implement: for each Done-When item, write a failing test first, then the minimum code to make it pass (red-green).
Skill Claude CodeCodex
Guides module and API design using APOSD principles: generates multiple design alternatives, compares them on information hiding and interface depth, and produces a documented design decision. For creating new module/API design; not for assessing existing designs (use aposd-reviewing-module-design) or routine-level…
Skill Claude CodeCodex
Assesses existing module and interface design for complexity symptoms: information leakage, shallow interfaces, pass-through layers, and unknown unknowns. Produces a structured assessment — not transformations (use aposd-simplifying-complexity to edit) and not new-design generation (use aposd-designing-deep-modules).
Skill Claude CodeCodex
Transforms complex code by applying APOSD's pull-complexity-downward principle: resolves error hierarchies, collapses configuration, and moves caller-side logic into modules. Produces edited code; not for assessment-only review (use aposd-reviewing-module-design) or designing new modules from scratch (use…
Skill Claude CodeCodex
Verifies implementation completeness across functional correctness, error handling, concurrency, and security dimensions using APOSD's post-implementation checklist. Run after a coding task is nominally complete, not during active bug investigation (use cc-debugging).
Skill Claude CodeCodex
Applies Clean Architecture's dependency-direction and SRP-by-actor rules to system-level boundary design: separates business logic from infrastructure, identifies actor-coupling risks, and enforces inward-pointing dependency arrows. For system scope (multiple components, layers, or services), not routine or module…
Skill Claude CodeCodex
Audits and restructures control flow using Code Complete's nesting, cyclomatic complexity, loop design, guard-clause, and boolean simplification rules. Covers deep nesting, loop exit design, index naming, and callback chains. For statement-level flow inside a routine; not for routine/class structure (use…
Skill Claude CodeCodex
Applies Code Complete's scientific debugging method: STABILIZE → LOCATE → HYPOTHESIZE → EXPERIMENT → FIX → TEST → SEARCH. For active bug investigation, not QA process design or test coverage planning (use cc-quality-practices).
Skill Claude CodeCodex
Applies Code Complete's defensive programming rules: barricade design, assertion vs error-handling selection, input validation policy, and correctness-vs-robustness strategy for the current context. For hardening code at trust boundaries; not for diagnosing an active failure (use cc-debugging) or post-completion…
Skill Claude CodeCodex
Structures routine design through pseudocode-first iteration: clarifies naming and purpose before any code, catches design flaws cheaply, and prevents compile-debug loops on poorly understood routines. For designing a routine before writing it; not for assessing routines that already exist (use…
Skill Claude CodeCodex
Applies Code Complete's QA process design: selects defect-detection techniques by phase, sizes the test suite, and designs review and inspection processes. For QA planning and process design, not active bug investigation (use cc-debugging).
Skill Claude CodeCodex
Guides safe refactoring using Code Complete's fix-first-then-refactor discipline: decides between refactor, rewrite, and fix-first; enforces separate commits; applies small-change rigor to high-error-rate one-liners. Not for diagnosing the bug itself (use cc-debugging), transforming working code's complexity (use…
Skill Claude CodeCodex
Applies Code Complete's routine and class design rules at the routine level: cohesion classification, parameter-count thresholds, LSP inheritance verification, and containment-vs-inheritance decision. For routine and class scope, not system architecture (use ca-architecture-boundaries).
Skill Claude CodeCodex
Decomposes underspecified requests by classifying gaps (missing info, ambiguity, false premises) and generating targeted clarifying questions. Produces a confirmed problem statement before any implementation begins. For sharpening a request that already exists; not for open-ended requirement discovery from a vague…
Skill Claude CodeCodex
Audits and improves code clarity and documentation using APOSD's obviousness rules: naming quality, comment accuracy, AI-facing doc completeness, and the comments-first workflow for new code. Not for generating project-wide convention docs (use code-standards) or structural simplification of the code itself (use…
Skill Claude CodeCodex
Generates or updates docs/code-standards.md by scanning the codebase for actual conventions. Produces an example-rich standards file optimized for LLM consumers, grounded in the project's real patterns. Not for auditing one file's naming, comments, or clarity (use code-clarity-and-docs).
Skill Claude CodeCodex
Maps code symptoms — exploding subclass combinations, switch-on-type dispatch, tangled object construction, incompatible interfaces, one-to-many update cascades — to the matching Gang of Four pattern, then loads that pattern's structural recipe from its 23 reference files. For selecting and implementing a design…
Skill Claude CodeCodex
Applies measure-first performance optimization: profiles to find hot spots, applies algorithm and data-structure improvements before micro-optimizations, and validates each change prevents regression. For single-process code tuning; not for correctness bugs (use cc-debugging) or concurrency, distributed, and real-time…
Skill Claude CodeCodex
Implements the Standard/Full planning pipeline for Medium and Complex tasks: multi-step discovery, phase decomposition with skill matching, cross-cutting concerns, and plan emission with Gate fields.
Skill Claude CodeCodex
Safely modifies untested legacy code by getting it under test first: characterization tests, seam identification, sprout/wrap techniques, and pinch-point testing before any production changes. Not for refactoring code that already has test coverage (use cc-refactoring-guidance).
