Review test quality and audit test coverage for any module. This skill should be used when reviewing existing tests, auditing test gaps, writing new tests, or when asked to assess test health. It pipelines testing standards into the audit workflow to produce a prioritized gap report. The output is a report, not code — do not write test implementations until the report is reviewed.

UncategorizedView skill →

testing-anti-patterns

Does not replace the formal review gates in agent-loops — this is for mid-implementation consultation.

UncategorizedView skill →

skill-creator

Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Codex's capabilities with specialized knowledge, workflows, or tool integrations.

UncategorizedView skill →

UncategorizedView skill →

agent-loops

Complete operational workflow for implementer agents (Codex, Gemini, etc.) making code changes and writing tests. Drives all work through atomic commits — each loop operates on the smallest complete, reviewable change. Defines the Code Change Loop, Test Writing Loop, Lint Gate, and Issue Filing process with circuit breakers, severity levels, and escalation rules. Requires `cortex git commit` for all commits. Includes bundled provider-aware review scripts that keep same-model shell-outs as the last resort, plus a fresh-context Codex fallback for code review and test audit. Use this skill when starting any implementation task.

ai-tells-review

Use when public prose still sounds machine-written after ai-tells-scan. Complements ai-tells-scan's mechanical pass with structural judgment: rhythm, hedging, rhetorical reflexes, and performative emphasis. Trigger on 'review for AI tells,' 'does this read AI,' 'strip the AI smell,' or 'make this less AI.'

UncategorizedView skill →

ai-tells-scan

Use when writing tasks produce prose artifacts (READMEs, docs, PR text, tutorials, guides, posts, release notes) and need a fast surface scan for AI tells. Auto-engages on prose writing tasks; checks banned punctuation, stock vocabulary, and mechanical patterns. For the structural judgment pass on rhythm and rhetorical reflexes, use ai-tells-review. Not a replacement for voice skills like nick-voice; this removes machine fingerprints, it does not add a target voice.

UncategorizedView skill →

architectural-analysis

User-triggered deep architectural analysis of a codebase or scoped subtree across eight modes — information architecture, data flow, integration points, UI surfaces, interaction patterns, data model, control flow, and failure modes. This skill should be used when the user asks to "diagram this codebase," "map the architecture," "show the data flow," "give me an ERD," "trace control flow," "find the integration points," "verify the layout pattern," "audit the UX architecture," or any similar request whose primary deliverable is mermaid diagrams plus cited reports under docs/architecture/. Dispatches haiku/sonnet sub-agents in parallel for per-mode exploration, then verifies every citation mechanically before any node lands in a diagram. Not for one-off prose explanations of code (use code-explanation) or for high-level system design from scratch (use system-design).

UncategorizedView skill →

async-python-patterns

Python asyncio and concurrent programming patterns for high-performance applications. Use when building async APIs, concurrent systems, or I/O-bound applications requiring non-blocking operations.

UncategorizedView skill →

atlas-crew-tasks

Use when filing, updating, sequencing, or querying tasks in any atlas-crew repo (Facet + the Atlas Crew Security repos: Apparatus, Chimera, Crucible, Synapse, Bridge). These repos track work in GitHub Issues on Projects v2 boards, NOT backlog.md. Covers the two boards, the Type/Area/Status field model, cross-repo Initiative grouping, gh seq execution ordering, and the non-obvious gh/GraphQL mechanics for setting issue types and project fields. Trigger on: file an issue, create a task, set priority/type/area/status, add to board, what should I work on next, execution order, sequencing, blocked-by, milestone, where does this task go.
