Quality

Content

100%Weight 40%Scale 1-3

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is a lean, highly actionable routing skill with concrete commands, explicit state handling, and verification checkpoints for credential operations. It assumes Claude's competence and is well-organized as a single file with no padding.

Dimension	Reasoning	Score
Conciseness	Lean and efficient throughout — the intro, schema, and routing sections assume Claude's competence and every section earns its place with no padded explanations of concepts Claude already knows; not score 2 because there is no unnecessary explanation to tighten.	3 / 3
Actionability	Provides concrete, copy-paste-ready `python3 $PLUGIN_ROOT/skills/mixpanelyst/scripts/auth_manager.py <subcommand>` commands and specific JSON-field handling for each branch; not score 2 because guidance is fully executable rather than pseudocode or abstract.	3 / 3
Workflow Clarity	Clear argument-based routing with per-subcommand sequences and explicit verification checkpoints (e.g. `account test` after add/login) plus state-switch error handling for credential operations; not score 2 because validation/feedback loops are present, not merely implied.	3 / 3
Progressive Disclosure	A single well-organized SKILL.md with clearly signaled sections and no nested multi-level references; the bundle has no separate reference/script files to split out, so the well-structured single file fully satisfies the simple-skill exception; not score 2 because organization is clear and navigation is easy.	3 / 3

Description

67%Weight 40%Scale 1-3

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is specific and well-scoped to a clear niche, listing many concrete auth-management actions. Its weakness is the absence of an explicit "Use when..." trigger clause and a slightly product-jargon-heavy term set.

Suggestions

Add an explicit "Use when..." clause naming natural triggers, e.g. "Use when the user needs to log in to Mixpanel, add or switch Mixpanel accounts/projects, or check Mixpanel auth status."

Soften product jargon by adding user-facing phrasings alongside internal terms, e.g. "log in to Mixpanel" / "Mixpanel login" rather than only "Headless authentication" and "bridge credentials".

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — "check session state, list/add/use accounts, run OAuth login, switch projects/workspaces, manage targets, and check bridge credentials" — matching the multiple-specific-actions anchor; not score 2 because coverage is comprehensive rather than partial.	3 / 3
Completeness	Clearly states what the skill does but lacks an explicit "Use when..." trigger clause, which per the judging guidelines caps completeness at 2; not score 1 because the "what" is unambiguous, not score 3 because the "when" is absent.	2 / 3
Trigger Term Quality	Includes relevant terms ("Mixpanel", "OAuth login", "accounts", "projects", "credentials") but leans on product-specific jargon ("Headless authentication", "bridge credentials", "targets") and misses common natural phrasings a user would say; not score 3 because natural-term coverage is incomplete.	2 / 3
Distinctiveness Conflict Risk	A narrow Mixpanel-Headless-auth niche with distinct triggers unlikely to overlap with other skills; not score 2 because it is clearly scoped rather than merely somewhat specific.	3 / 3
