Collects the syntax rules and failure modes that trip up PowerShell scripting on Windows -- operator grouping, ASCII-only output, null guards, JSON depth, and error-handling structure. It pairs each pitfall with the corrected form so scripts run reliably under Set-StrictMode. Use it when authoring or debugging…

Designs production prompts for LLM-powered features — clear instructions, role/system prompts, few-shot examples, structured output schemas, delimiter structuring, and reasoning strategy. Use when building or debugging an LLM feature (extraction, classification, generation, agents), when output is inconsistent or…

Guides Python design decisions -- framework choice, async-vs-sync, typing strategy, project layout, and error handling -- by reasoning from the project's needs rather than copying snippets. It explains when async helps, when Pydantic earns its place, and how to keep logic out of the view layer. Use it when writing…
Skill Claude CodeCodex
Guides an engineer or agent through ingesting code-review feedback and revising well — triaging comments into must-fix, nit, and question, replying to each without defensiveness, grouping related changes, pushing back with evidence when warranted, and re-requesting review. Use when a pull request has review comments…
Skill Claude CodeCodex
Organizes adversary-simulation work around the MITRE ATT&CK lifecycle -- recon, access, escalation, evasion, lateral movement, and impact -- with the goal of exposing detection gaps. It pairs each phase with objectives and emphasizes scope, minimal impact, and reporting. Use it when scoping a penetration test, running…

Covers production Rust on the 2024 edition -- ownership and lifetimes, async with Tokio, the trait and type system, performance work, and safe handling of unsafe and FFI. It leans on current ecosystem crates (axum, tower, sqlx, serde, thiserror) and idiomatic error handling. Use it when building Rust services or…
Skill Claude CodeCodex
Core search-engine optimization guidance spanning the E-E-A-T quality signals, Core Web Vitals, technical foundations like sitemaps and canonicals, on-page content and meta elements, schema markup, and ranking priorities. Use it when optimizing pages for search, writing title and meta tags, strengthening trust…
Skill Claude CodeCodex
Frames production server operations as decisions -- which process manager to run, what to monitor and alert on, how to handle logs, and when to scale up versus out. It reasons from symptoms and goals rather than reciting commands, and includes a triage order for incidents. Use it when keeping a service running…
Skill Claude CodeCodex
Cuts away accidental complexity from working code by deleting dead branches, collapsing needless layers of indirection, un-nesting control flow, and reducing parameter lists, all while keeping observable behavior identical. Applies when a file feels over-built, more abstract than its single use justifies, or harder to…
Skill Claude CodeCodex
Turns a recurring, multi-step way of working into a packaged, reusable SKILL.md that any agent can later discover and follow. Fits when the same kind of request has come up several times, when a procedure has enough stable steps to be worth recording, or when someone explicitly asks to capture a workflow as a skill.…
Skill Claude CodeCodex
Drives a feature through three approved artifacts — requirements, design, then tasks — before any code is written, enforcing a left-to-right gate so design is settled before implementation. Use when starting a non-trivial feature, a multi-file change, or anything ambiguous, fuzzy, or risky. Maps the workflow onto…
Skill Claude CodeCodex
Provides a disciplined, evidence-first method for tracking down stubborn defects, moving from reliable reproduction to isolation, then to a proven root cause, and finally to a verified fix. Suited to bugs that resist quick guesses, intermittent or environment-specific failures, and regressions where the cause is not…
