Conciseness

The body is dense and specific — tables for tools, policy fields, and endpoints with almost no explanation of concepts Claude already knows. Not 5: the seven-layer 'Why this is safe even though the dashboard CAN edit the policy' narrative, the dashboard endpoints table, and the 'Credit accounting' section add tokens that could be trimmed or externalized.

Actionability

Fully executable throughout: exact tool invocations ('chaingpt_agent_wallet_sign_and_send chain=… to=… valueWei=… data=… memo="…"'), a copy-ready production policy.json, concrete setup commands for both passphrase options, and a keychain export command for backup. Common cases (setup, funding, pre-flight, refusal handling) are all covered with concrete examples.

Workflow Clarity

Clear sequences with explicit validation: setup options A/B, a numbered pre-flight checklist (status → balances → policy → sign) before any signing, and an explicit refusal feedback path ('do not try to work around it… surface the reason to the admin'). Not 5 because the 'What this skill does NOT do' section states Solana signing is 'not yet wired' and ERC-4337 is 'a future feature', directly contradicting the v1.19/v1.21 sections above and creating real workflow ambiguity for the agent.

Progressive Disclosure

There are no bundle files (no references/, scripts/, or assets/) and no external references at all — everything lives in one ~245-line SKILL.md. Section headers are clear, but content that clearly belongs in separate files (the Solana wallet guide, ERC-4337 session-key details, dashboard endpoint reference, full policy field reference) is inlined, matching anchor 3 rather than 4.

Specificity

Lists multiple concrete capabilities — 'Encrypted keystore (AES-256-GCM, scrypt KDF)', 'policy file the agent has no tool to write', 'deterministic policy gate on every signing operation', 'optional local HTTP dashboard' — covering the skill's full surface with no generic filler. Anchor 5 fits: comprehensive coverage of specific concrete capabilities; anchor 4 would require minor gaps, which are absent.

Completeness

Explicitly answers what ('its own EVM wallet with admin-controlled policies', keystore, policy gate, dashboard) and when via a dedicated 'Triggers:' clause listing concrete trigger phrases — an explicit 'Use when' equivalent, so the completeness cap of 3 does not apply and the anchor-5 example structure is matched.

Trigger Term Quality

The 'Triggers:' clause contains natural user phrasings like 'agent wallet', 'give the agent a wallet', 'fund the agent', and 'kill switch', plus adjacent-feature terms ('ERC-4337 alternative', 'session-key alternative'). Not 5 because common variations such as 'crypto wallet', 'hot wallet', or 'agent spending limits' are missing.

Distinctiveness Conflict Risk

Occupies a clear niche (admin-controlled agent EOA wallet) with distinctive triggers like 'policy gate', 'bounded autonomy', and 'kill switch' that are unlikely to fire a different skill. Not lower: no meaningful overlap with generic wallet or permission skills.
