Checks pip requirements and constraints files offline before they break a build - unpinned and lower-bound-only packages, PEP 440 specifier conflicts across files and markers, git refs without a commit hash, editable and local paths, partial hash mode, pre-releases, --extra-index-url dependency confusion, http indexes, stdlib backports, dev tools in runtime files and pip freeze drift. Includes a stdlib Python checker with --self-test.
Decodes a JWT without trusting it and lints the header and claims: alg none, remote jku/x5u keys, missing or expired exp, nbf/iat clock skew, millisecond timestamps, long lifetimes, iss/aud mismatches, sensitive data in the payload, and HMAC signature checks with a secret from an env var. Use when a login or API call fails with 401, or when reviewing token settings. Includes a stdlib Python inspector with --self-test.
Turns noisy application, server, and access logs into a ranked list of error patterns with counts, first and last seen, spikes, and patterns that are new versus a known-good baseline, then separates root causes from symptoms and writes a short incident triage report. Includes a tested stdlib Python log clusterer.
Reviews Dockerfiles for security, image size, build cache, and runtime reliability: secrets baked into layers, running as root, unpinned base images, curl piped to a shell, ADD misuse, leftover apt and pip caches, cache-busting dependency installs, shell-form CMD, and missing multi-stage builds or health checks, then writes a corrected Dockerfile and .dockerignore. Use when a user shares a Dockerfile and asks "review my Dockerfile", "why is my image so big?", or "is this container secure?".
Explains Python regular expressions token by token, tests them on must-match and must-not-match samples with spans and named groups, and flags risky patterns: nested quantifiers that backtrack catastrophically, [A-z], unescaped dots, empty matches, and missing anchors, then proposes a safer rewrite. Use when a user asks "what does this regex do?", "why doesn't it match?", or "is this regex safe?". Includes a tested stdlib Python checker.
Red-teams agent prompts and tools for prompt injection, tool abuse, and untrusted-content paths.
Compares environment variables across local, staging and production, finds missing, unused or mismatched settings before they break a deploy, and keeps your example env file honest.
Checks your servers over SSH on a schedule: disk, memory, failing services, certificate expiry and suspicious logins, then sends a short health report and alerts only when something needs you.
Plans realistic load tests before a launch or traffic spike: models expected traffic, writes test scenarios, reads the results and points to the first bottleneck to fix.
