88%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A highly operational skill body: executable commands for every operation, explicit human-approval checkpoints with unattended-run fallbacks, and real error-recovery guidance. The only soft spots are repeated approval-gate phrasing across sections and a monolithic single-file layout that could split the safety procedures from the API reference.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense and operational — complete curl commands, MCP tool names, error codes — with almost no explanation of concepts Claude already knows; the only trimmable fat is the approval-gate language repeated across 'Before Sending', 'Links and Codes', 'Receive and wait', and 'Tips' (e.g., 'wait for a yes before opening the link or using the code' appears three times). This fits 'efficient; minor instances of over-explanation that could be trimmed' rather than the every-token-earns-its-place anchor. | 4 / 5 |
Actionability | Fully executable, copy-paste-ready curl commands for onboarding, sending (with Idempotency-Key), listing, waiting, and replying; named MCP tools for each operation; a worked user/agent example; and concrete error semantics ('HTTP 409 inbox_exists means the name is taken', 'timed_out: true means nothing arrived; call again') covering the common cases. | 5 / 5 |
Workflow Clarity | The 'What This Skill Does' section sequences the full flow (reuse/create key → connect MCP → send → read → wait → reply) and the required sections add explicit validation checkpoints with feedback loops: preview-then-explicit-yes before every irreversible send, draft-and-stop fallbacks for unattended runs, the 409/timeout recovery paths, and the untrusted-data handling for links and codes. This matches the 'clear sequence with explicit validation steps; feedback loops for error recovery' anchor. | 5 / 5 |
Progressive Disclosure | A single well-organized SKILL.md (~112 lines) with clear section headers and one-level-deep external pointers (llms.txt, the GitHub repo) that are clearly signaled in Tips; however, everything lives inline in one file with no split of the safety procedures from the API quick-reference, so it sits at 'good structure; most content appropriately placed; minor organization gaps' rather than the well-split five. | 4 / 5 |
