Finds what you cannot see in pasted code, configs, prompts and data files - Trojan Source bidi controls, hidden Unicode tag text (prompt injection), zero-width and invisible characters, odd spaces, control characters, Cyrillic/Greek homoglyphs, mojibake, invalid UTF-8, BOMs, mixed line endings and non-NFC text. Decodes hidden text, ranks findings and writes a cleaned copy. Includes an offline stdlib Python checker with --self-test. 来源：https://prompts.chat/prompts/cmvxi5t8a0001l208j321df3j
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. 来源：https://prompts.chat/prompts/cmvexfiys000njr08n2k8i3bq
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. 来源：https://prompts.chat/prompts/cmvyxzied0001k108wkm9h02b
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. 来源：https://prompts.chat/prompts/cmv6cvanx0008kx06yf135t8x
Reviews nginx.conf and site configs for security problems such as TLS 1.0/1.1, weak ciphers, missing HSTS and security headers, the add_header inheritance trap, alias off-by-slash path traversal, autoindex, unlimited body size, $uri in redirects, HTTP without an HTTPS redirect, open admin paths and logins without rate limits. Gives a fixed config. Includes a stdlib Python checker with --self-test. 来源：https://prompts.chat/prompts/cmvoxlypi000bkz08hly85q7t
