Skill Claude CodeCodex
Design, create, restructure, polish, and visually QA editable presentation decks in PowerPoint or Google Slides through a reusable production harness. Use when Codex must create or revise a deck, follow or change a user-selected presentation mode, style, art direction, or slide template, port a story into an existing…
Skill Claude CodeCodex
Use when work crosses process boundaries — queues, webhooks, background jobs, retries, multi-service writes. Idempotency, delivery semantics, and failure design rules.
Skill Claude CodeCodex
FastAPI service-layer architecture, dependency injection, domain-error handling, SQLAlchemy 2.0 async, and Alembic conventions. Use when building or modifying FastAPI apps, in addition to python-patterns.
Skill Claude CodeCodex
Use when choosing a branching strategy, hunting a regression with git bisect, running multi-worktree development, or configuring CODEOWNERS and merge queues — falsifiable conventions, not a git tutorial.
Skill Claude CodeCodex
Use for GitHub repo operations via the gh CLI — issue triage, PR and CI management, releases, Dependabot — plus CODEOWNERS, reusable workflows, and monorepo path filtering. For operational tasks beyond plain git.
Skill Claude CodeCodex
Use when writing or reviewing Go concurrency, context handling, module boundaries, or reliability code — errgroup, worker pools, goroutine-leak avoidance, retry and circuit-breaking. Falsifiable rules, not idiom lists.
Skill Claude CodeCodex
Use when writing or reviewing Go tests — table-driven suites, golden files, fuzzing, benchmarks, race-exposing tests, testcontainers integration, or t.Parallel hazards. Falsifiable rules, not a tour of the testing package.
Skill Claude CodeCodex
Use when creating or editing hookify rule files (ECC plugin format) that intercept bash commands, file edits, or prompt events — rule syntax, patterns, and configuration guidance.
Skill Claude CodeCodex
Use when production is broken or degraded — mitigation-first response, timeline capture, severity ladder, and blameless postmortems. Agent-loop failures go to agent-introspection-debugging instead.
Skill Claude CodeCodex
Use when building or debugging an MCP server — tool/resource/prompt registration, tool-description engineering, the isError contract, authz and path sandboxing, stdio vs Streamable HTTP. Node/TypeScript SDK; defer to Context7 for current signatures.
Skill Claude CodeCodex
Use when adding logging, metrics, tracing, alerts, or SLOs to a service — structured-log contracts, RED metrics, trace propagation, symptom-based alerting.
Skill Claude CodeCodex
Forces the laziest solution that actually works, simplest, shortest, most minimal. Channels a senior dev who has seen everything: question whether the task needs to exist at all (YAGNI), reach for the standard library before custom code, native platform features before dependencies, one line before fifty. Supports…
Skill Claude CodeCodex
Python style, typing, side-effect, error-handling, async, and tooling conventions (ruff, uv, pytest, pydantic-settings). Use when writing or reviewing Python code.
Skill Claude CodeCodex
React Native platform, Metro-port and emulator/simulator worktree isolation, and cleanup conventions (expo-dev-client, adb, avdmanager, simctl). Use when working on React Native apps.
Skill Claude CodeCodex
Decision framework for choosing between regex and LLM when parsing structured text — start with regex, add LLM only for low-confidence edge cases.
Skill Claude CodeCodex
Research-before-coding workflow. Search for existing tools, libraries, and patterns before writing custom code. Invokes the researcher agent.
Skill Claude CodeCodex
Use when designing anything with a trust boundary — auth systems, secrets handling, service-to-service calls, user input surfaces. Design-time security; review-time checks live in the core doctrine.
Skill Claude CodeCodex
Evidence-first repo execution workflow. Use when the user wants a command run, a repo checked, a CI failure debugged, or a narrow fix pushed with exact proof of what was executed and verified.
Skill Claude CodeCodex
TypeScript/Node conventions — strict compiler settings, parse-don't-cast boundaries, Result-style domain errors, floating-promise hygiene, ESM. Use when writing or reviewing TypeScript.
Skill Claude CodeCodex
Two-loop UI/UX discipline — a cold-context grader scores renders against an 8-dimension rubric with binary preservation and audit gates while the implementer iterates from critique briefs; the impeccable skill is a hard precondition. Use when asked to improve UX, flow, layout, register, or polish on a page or…
