使用说明 (SKILL.md)

axiom-json-canonicalizer

Version: 1.0.1 Axioma Tools

Converts any JSON to a canonical form per RFC 8785 (JCS).

What this skill does

Object keys sorted lexicographically (post-NFC)
No insignificant whitespace
Numbers: ECMAScript shortest round-trip
Strings: NFC-normalized, surrogate-pair safe
Output: UTF-8 bytes (byte-to-byte stable)

When to use this skill

✅ Sign OAuth/JWT payloads (canonicalize before signing)
✅ Hash JSON for integrity verification
✅ Compare semantically-equivalent JSON
✅ Build tamper-evident audit logs
❌ Need pretty-printing (use json.dumps indent)
❌ Need JSON5/JSONL/JSONC (different specs)

Usage

python3 axiom_json_canonicalizer.py input.json > canonical.json
python3 axiom_json_canonicalizer.py input.json --verify canonical.json

from axiom_json_canonicalizer import canonicalize
canon_bytes = canonicalize(json_obj)  # UTF-8 bytes

Validation

Check	Status
Unit tests	81 cases
Performance	\x3C100ms
Security	Pure stdlib, no injection
Determinism	Byte-to-byte stable
License	Apache-2.0

安全使用建议

Treat this as a custom offline JSON normalizer unless the publisher fixes or narrows the RFC 8785/JCS claims. Do not rely on it for cryptographic signatures, JWT/OAuth payloads, audit logs, or interoperability with other JCS implementations without independent test vectors and agreement that NFC normalization and its number formatting are acceptable.

能力评估

⚠ Purpose & Capability

The skill is coherently aimed at JSON canonicalization for hashing/signing, but it advertises RFC 8785/JCS compliance while the code intentionally NFC-normalizes strings/keys and uses non-strict number handling, which is unsafe for a claimed standards-compatible signing or integrity tool.

⚠ Instruction Scope

Runtime use is user-directed through stdin or a named file, but the docs repeatedly recommend OAuth/JWT signing, hashing, and tamper-evident logs without clearly warning that its output is a custom canonical form rather than strict JCS.

✓ Install Mechanism

No install script, postinstall hook, package manager mutation, or automatic execution was found; the artifact is documentation, a Python script, tests, and metadata.

ℹ Credentials

The Python code uses only stdlib JSON/string/file operations and no network, subprocess, shell, LLM, or credential access. Registry capability tags mention sensitive credentials/OAuth, but the artifact does not request or use them.

✓ Persistence & Privilege

No persistence, background worker, privilege escalation, hidden state, or broad filesystem indexing was found; file access is limited to user-supplied paths and stdout output.
