You say
Fix the intermittent race condition occurring during concurrent user logins in the Auth Provider. Keep the scope tight and prove the fix works.
Your agent does
TASK: Fix race condition in Auth Provider SCOPE: Narrow (Auth.ts only) VERIFICATION: Reproduced failure with concurrent login script. Verified fix with 100 iterations of 'npm test auth/'. RISK: Low. Change is isolated to the locking mechanism. RESIDUAL: Possible 50ms latency increase.

About This Skill
Level up your agent's engineering discipline
Codex-Grade Coding is a high-performance protocol designed to transform standard AI agents into disciplined senior engineers. It solves the common problem of "drift" and "over-coding" by enforcing a strict operational framework that prioritizes task classification, scope control, and evidence-based verification.
What it does
Instead of jumping straight into code, this skill forces the agent to classify the task (Trivial, Standard, Risky, or Review) and select an appropriate "Verification Ladder" step. It constrains the agent to the narrowest viable change, preventing unnecessary refactors or "hallucinated cleanup" that often introduces bugs in complex codebases.
Why use this skill
While basic prompting might get the code written, Codex-Grade Coding ensures the work is proven. It is particularly effective for making smaller or less reliable models perform at a Much higher tier by providing a repeatable engineering bar. The output adheres to a strict "Final Answer Contract," making it easy for human developers to verify what was changed and why.
Supported workflows
- Bug Fixes: Mandatory reproduction steps before applying fixes.
- Refactoring: Forced proofs that behavior remains unchanged.
- Code Reviews: Findings prioritized by correctness and regression risk.
- Benchmarking: Includes a rubric to score agent performance on scope discipline and hallucination control.
Use Cases
- Enforce senior-level coding standards on weaker AI models
- Prevent scope creep and unnecessary code changes during refactors
- Standardize bug reports with mandatory verification evidence
- Systematically benchmark and score AI coding performance
Known Limitations
- Overhead for very small tasks.
- Dependency on external tool access (terminal/test runner) for full verification.
- Best results require models with strong reasoning (LLM-as-judge).

diagnosing-rag-failure-modes
RAG fails quietly. It retrieves documents, returns confident-looking answers, and misses the question entirely — because the question required connecting facts across documents, reasoning about sequence, or tracing causation. This skill gives you a five-question diagnostic checklist that classifies any failing query as either RAG-safe or structurally RAG-incompatible, then maps it to the specific failure pattern and the architectural fix that resolves it.
Legacy Code Modernization Planner for AI Coding Agents
Creates safe modernization roadmaps for old, messy, undocumented, or fragile codebases, including risk audits, refactor phases, dependency reviews, testing plans, migration steps, and AI coding prompts.
designing-hybrid-context-layers
Architects the right retrieval strategy for every query — teaching your agent when to use RAG, a knowledge graph, or a temporal index instead of defaulting to vector search for everything.
