Skill Claude CodeCodex
List every registered skill across the roots in /.sc/repos.patterns. Use when the user asks "list my skills", "what skills do I have", "show all skills", "enumerate skills", "skill inventory", "skills installed", or wants a flat catalog rather than a ranked search. Unlike sc:search (which ranks by query relevance)…
Skill Claude CodeCodex
Search across all registered skill repos for a skill that matches the user's intent. Use when the user asks "do I have a skill for X", "which skill does Y", "find a skill that …", "is there a skill to …", "list my skills", or any "find/locate/search for a skill" phrasing. The script takes THREE positional queries…

Use WHEN you just pushed new assets to S3 and need CloudFront to stop serving the cached old version — issue a targeted invalidation without nuking the whole cache.
Skill Claude CodeCodex
Use WHEN you need to audit AWS IAM — find stale access keys, over-privileged roles, unused users, and policies that grant : — before a compliance review or incident.
Skill Claude CodeCodex
Use WHEN you need to deploy or update an AWS Lambda function — upload code, set env vars from .env, configure layers, and route traffic via aliases without downtime.
Skill Claude CodeCodex
Use WHEN you need to mirror files between a local directory and an S3 bucket, with optional deletion of orphans, dry-run previews, and exclude patterns.
Skill Claude CodeCodex
Use WHEN you need to base64-encode or decode a string, file, or pipe — with URL-safe variants, line-wrapping control, and a quick check for double-encoding.
Skill Claude CodeCodex
Use WHEN you've written a shell script and want it checked for common footguns — unquoted variables, missing set -euo pipefail, broken globs, portability issues — before committing.
Skill Claude CodeCodex
Use WHEN you've changed AWS CDK code and want to see exactly which CloudFormation resources will be created, modified, replaced, or destroyed before deploying.
Skill Claude CodeCodex
Use WHEN you want a searchable history of everything you've copied recently — so you can paste something from two hours ago without recomputing it.
Skill Claude CodeCodex
Produce an HTML coverage report, open it in the browser, and surface every source file below the 80% line-coverage threshold.
Skill Claude CodeCodex
Use WHEN you have a single CSV file containing duplicate rows and want to collapse them — exact-match, key-column-match, or fuzzy-match — with a report of what was removed.
Skill Claude CodeCodex
Use WHEN you have two or more CSV files sharing a key column and need to outer-join them into a single deduplicated table, written to a file or piped to stdout.
Skill Claude CodeCodex
Use WHEN you've been handed a CSV and need a quick column-by-column profile — null rate, distinct count, top values, min/max for numeric columns — without writing a pandas describe().
Skill Claude CodeCodex
Use WHEN you need to assert a CSV file matches an expected schema — required columns present, types coerce, regex patterns hold, no nulls in non-null columns — before downstream ingestion.
Skill Claude CodeCodex
Use WHEN you need to apply a forward database migration safely — Alembic, Flyway, Goose, or knex — with a pre-check, transaction wrapping, and a verify step.
Skill Claude CodeCodex
Use WHEN a sharded database has uneven load — one shard handling 80% of traffic — and you need to plan and execute a shard rebalance with minimal downtime.
Skill Claude CodeCodex
Use WHEN you need to audit a project's third-party dependencies for known CVEs across npm, pip, Go, and Cargo, with a unified severity report suitable for PR review.
Skill Claude CodeCodex
Locate the top-N largest directories and files under a given path, starting with a fast approximate pass and refining only if the user wants exact bytes.
Skill Claude CodeCodex
Use WHEN you need to build a Docker image with BuildKit, leverage a remote layer cache to speed up CI, and push the result to a registry.
Skill Claude CodeCodex
Use WHEN you need to bring up a local multi-service stack from docker-compose.yml, with healthchecks honored, env loaded, and clean shutdown semantics.
Skill Claude CodeCodex
Use WHEN docker is eating disk — reclaim space from dangling images, stopped containers, unused volumes, and build cache without nuking what you still need.
Skill Claude CodeCodex
Use WHEN you need to write or refactor a Dockerfile so the final image is small — multi-stage builds that drop compilers, test deps, and intermediate artifacts.
