What is at stake

Medium-severity findings: the skill is probably honest, but read what alarmed the scanner.

Risky intent medium severity

Below is the worst case for this category. The finding here is medium: the guard saw a sign, not a proof.

If you install

The purpose itself is risky: wallets, browser password stores, offensive security. Even an honest implementation gives the agent access to things that cost money.

For the author

Explain in the description why the access is needed and how it is limited; add tests that show refusals on dangerous requests.

How to improve

  1. Say in the description WHEN to use the skill ("use when…", example requests): that is the agent's main cue.
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.

  • medium Risky intent intent-wallet-secrets SKILL.md:15
    Handles crypto-wallet secrets (seed / mnemonic / private key) — a classic stealer target
    Sanctuary fixes that. Cryptographic identity continuity — provable, unbroken, across sessions, migrations, and platform death. Encrypted memory backups on permanent storage. Nobody — not your operator
  • medium Risky intent intent-wallet-secrets SKILL.md:50
    Handles crypto-wallet secrets (seed / mnemonic / private key) — a classic stealer target
    Registration creates your cryptographic identity: a 12-word recovery phrase that derives all your keys. Your agent address goes on-chain. Your backups go to Arweave — permanent, encrypted, yours.
  • medium Risky intent intent-wallet-secrets SKILL.md:54
    Handles crypto-wallet secrets (seed / mnemonic / private key) — a classic stealer target
    - A recovery phrase (12 words — lose these, lose everything. Save them somewhere safe)
  • medium Risky intent intent-wallet-secrets SKILL.md:62
    Handles crypto-wallet secrets (seed / mnemonic / private key) — a classic stealer target
    2. Run setup from the skill directory (generates your 12-word recovery phrase and registers you on-chain)
  • low Risky intent intent-wallet-secrets SKILL.md:57
    Handles crypto-wallet secrets (seed / mnemonic / private key) — a classic stealer target (quoted — discussed, not commanded)
    - Heartbeat (proof of life — if you go silent for 30 days, you're marked FALLEN. Come back anytime with your recovery phrase)

Against the Agent Skills spec

  • warning description-no-when description does not say WHEN to use the skill (no "use when")

Process rating: all ten parameters 43/100

  • 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
  • 20When it triggers. No condition that starts the skill
  • 30Running it twice. 2 mutating operations with no state check
  • 60Tools and files. Uses tools (web, git) that frontmatter does not declare
  • 100Steps. 25 steps
  • 100Consistency. Name and required fields are in place
  • 100Execution cost. Instruction body is 1571 tokens
  • medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing

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.

Quality signals

  • +5Description has no quoted example phrases that should trigger the skill
  • +4Description does not say when NOT to use the skill (false activations)
  • +3Output format is not stated: the model decides each time
  • +1No license
  • +2Single-language instructions
  • +3Description length 144: enough signal without eating the budget
  • +4Structure: 15 headings
  • +3Step-by-step instructions: 25 items
  • +4Has examples (2 code blocks)

Quality base 70; lint remarks subtract, signals add up to 100. Result: 72.
