Discovery
82%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is a strong description that clearly identifies the tool (himalaya), its domain (CLI email management), and lists comprehensive specific actions. The main weakness is the absence of an explicit 'Use when...' clause, which would help Claude know exactly when to select this skill. The technical specificity and unique tool name make it highly distinctive.
Suggestions
Add an explicit 'Use when...' clause, e.g., 'Use when the user asks about managing email from the command line, mentions himalaya, or needs to interact with IMAP/SMTP mailboxes.'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: list, read, write, reply, forward, search, and organize emails. Also mentions specific protocols (IMAP/SMTP), multiple accounts support, and MML composition. | 3 / 3 |
Completeness | Clearly answers 'what does this do' with specific actions and capabilities, but lacks an explicit 'Use when...' clause or equivalent trigger guidance. The when is only implied by the nature of the actions described. | 2 / 3 |
Trigger Term Quality | Includes strong natural trigger terms users would say: 'emails', 'IMAP', 'SMTP', 'terminal', 'himalaya', 'reply', 'forward', 'search', plus the tool name itself. Covers common email-related actions and the CLI context well. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive due to the specific tool name 'himalaya', the CLI/terminal context, IMAP/SMTP protocols, and MML. Unlikely to conflict with other skills as it occupies a very clear niche of terminal-based email management. | 3 / 3 |

Implementation
64%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a solid, actionable reference for the Himalaya CLI with excellent concrete examples covering all major operations. Its main weaknesses are the lack of workflow sequencing with validation checkpoints (e.g., verifying config before sending) and some content that would be better placed in the referenced files rather than inline. The skill reads more like a command reference card than a guided workflow.
Suggestions
Add a validation workflow after configuration: e.g., run `himalaya account check` or `himalaya envelope list` to verify connectivity before proceeding to other operations, with error recovery guidance.
Move the full config.toml example to `references/configuration.md` and keep only a brief mention or minimal example in the main skill to improve conciseness and progressive disclosure.
Add a brief 'typical workflow' section showing a sequenced multi-step process (e.g., search → read → reply → verify sent) with explicit checkpoints.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is mostly efficient with concrete commands, but includes some unnecessary elements like the full config file example (which could be in the referenced configuration.md) and some light explanatory text that could be trimmed. The inline comments and parenthetical notes add minor bloat. | 2 / 3 |
Actionability | Every operation includes fully executable, copy-paste-ready bash commands with realistic arguments. The configuration example is complete with actual TOML syntax, and commands cover the full range of email operations with specific flags and options. | 3 / 3 |
Workflow Clarity | Individual commands are clear, but there's no sequenced workflow for common multi-step tasks (e.g., setup → verify → use). The prerequisites section lists requirements but doesn't include validation steps like verifying the config works before proceeding to email operations. No feedback loops for error recovery. | 2 / 3 |
Progressive Disclosure | References to configuration.md and message-composition.md are well-signaled, but the main file includes a full configuration example that arguably belongs in the referenced configuration.md. The skill is somewhat long (~150 lines) with content that could be better distributed across reference files. | 2 / 3 |
