Quality

Content

86%Weight 40%Scale 1-5

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 strong, executable conventions document: every pattern is stated as a hard rule with concrete names, commands, and working code examples, and the Anti-Patterns section converts each rule into an explicit prohibition. Its only weaknesses are minor redundancy between Patterns and Anti-Patterns and the absence of a verification workflow (e.g., run the test suite before declaring a change done), which is only weakly implied.

Suggestions

Add a short "When done" step (e.g., "Run npm test — node --test test/ — and confirm all tests pass on the change") to give the conventions an explicit validation checkpoint.

Trim the overlap between Patterns and Anti-Patterns: state each rule once in Patterns, and keep Anti-Patterns as terse one-line reminders rather than re-explaining the rationale.

Consider folding the file-structure ownership table (user-owned vs Squad-owned) into a single compact list, since it is the densest section and reads as two overlapping lists.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence ("Tests use node:test and node:assert/strict — no test frameworks"), with no padding or explanations of known concepts. Scored 4 rather than 5 because the Anti-Patterns section restates rules already fully specified in Patterns (zero-dep, path separators, fatal(), color constants), a minor duplication that could be trimmed.

4 / 5

Actionability

Fully executable guidance throughout: concrete function names (fatal(msg), copyRecursive(src, target)), exact color constants (GREEN, RED, DIM, BOLD, RESET), runnable commands (npm test, node --test test/), and a copy-paste-ready JavaScript Examples block covering error handling, Windows-safe paths, and the skip-if-exists pattern. Matches anchor 5 — code covers the common cases.

5 / 5

Workflow Clarity

This is a conventions skill rather than a multi-step workflow, and each convention is unambiguous with clear ownership rules ("Never overwrite user state during init. The upgrade flow overwrites only Squad-owned files") plus a validation signal ("All tests must pass on all platforms"). Scored 4 not 5 because there is no explicit sequenced workflow with checkpoints — e.g., how to verify a change before shipping an upgrade — though no destructive/batch workflow is being taught that would trigger the cap.

4 / 5

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ are absent) and none are needed: the ~61-line body is self-contained with clean sections (Context, Patterns, Examples, Anti-Patterns), no nested references, and no bulk content that belongs in a separate file. This fits the well-organized self-contained structure of anchor 5.

Description

40%Weight 40%Scale 1-5

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 concise and domain-scoped but under-specified: it says nothing about what the conventions actually cover (zero-dep, fatal(), path.join(), init idempotency) and gives no "Use when" trigger guidance. A user or Claude would not reliably know when to load this skill.

Suggestions

Enumerate the concrete capability areas in the description, e.g., "Covers zero-dependency constraints, the fatal() error pattern, ANSI color constants, Windows-safe path handling, and init idempotency rules in the Squad codebase."

Add an explicit trigger clause: "Use when modifying Squad source code, adding tests, or changing init/upgrade behavior in the create-squad CLI."

Include natural trigger terms users would actually say — "Squad CLI", "create-squad", "Squad conventions", "Squad coding standards" — to improve both trigger quality and completeness.

DimensionReasoningScore

Specificity

"Core conventions and patterns used in the Squad codebase" names a specific domain but lists no concrete actions or capabilities — "conventions and patterns" is generic. It does not reach anchor 3 because no concrete actions (e.g., error handling, testing, file structure conventions) are enumerated.

2 / 5

Completeness

It has a vague "what" (which conventions? for what tasks?) and no "when" trigger guidance at all — no "Use when..." or equivalent clause. This matches anchor 2 exactly (vague what, no when) and the missing-trigger cap of 3 applies regardless.

2 / 5

Trigger Term Quality

"conventions", "patterns", and "Squad codebase" are terms a developer might naturally say, but coverage is thin — missing obvious variations like "Squad CLI", "create-squad", "coding standards", or "project rules". Matches anchor 3: some relevant keywords but missing common variations.

3 / 5

Distinctiveness Conflict Risk

Scoping to "the Squad codebase" gives it a clear niche unlikely to fire for unrelated skills, with only minor overlap risk against other project-conventions skills in the same repo. Not 5 because the description itself doesn't state distinct triggers that would fully disambiguate it.
