AC encoding-toolkit

Multi-format encoder, decoder, and hasher supporting Base64, Base64URL, Base32, Hex, URL-encoding, HTML entities, ROT13, Binary, and ASCII85. Also computes MD5, SHA-1, SHA-256, SHA-512, and SHA3-256 hashes. Can auto-detect encoding format. Use when encoding or decoding data, computing file or string hashes, converting between formats, or identifying unknown encoded strings. Triggers on "encode base64", "decode hex", "hash sha256", "what encoding is this", "url encode", "html decode", "convert to binary".

How to improve

    For the model run — optional
    • Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
    • A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

    Process rating: all ten parameters 52/100

    • 0Result and completion. Does not say what the result is
    • 0Inputs and preconditions. Does not say what the process needs to start
    • 0Failures and branches. Linear process with no failure handling
    • 0Progress reporting. Says nothing while it works
    • 60Tools and files. Uses tools (python) that frontmatter does not declare
    • 70When it triggers. States when to use, but not when not to
    • 100Steps. 4 steps
    • 100Consistency. Name and required fields are in place
    • 100Execution cost. Instruction body is 347 tokens
    • 100Running it twice. No mutating operations

    Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.

    ClawHub: clean
    This is a straightforward local encoding, decoding, and hashing skill with user-directed file input and no evidence of hidden access, network activity, persistence, or exfiltration.
