Quality

Content

60%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 content is well-structured with a clear five-step workflow and useful tables, but it has notable gaps: the scope-analysis step contains only pseudocode comments instead of executable search commands, and the Anti-Rationalization section is non-actionable padding. Undefined comparison targets ('Superpowers', 'Specialist Agent') and undated volatile pricing further weaken actionability and conciseness.

Suggestions

Replace the comment-only pseudocode in Step 1 with actual executable commands using the declared tools (e.g., Glob patterns to find affected files, Grep to count matching lines), since allowed-tools already permits them.

Remove or drastically trim the Anti-Rationalization section — it argues for the skill's value rather than instructing Claude how to execute it.

Define or remove the undefined comparison fields ('Superpowers estimate', 'Specialist Agent estimate') and consider moving the volatile model-pricing tables to a reference file so stale prices don't clutter the main skill.

DimensionReasoningScore

Conciseness

The body is mostly efficient tables and templates, but the 'Anti-Rationalization' section ("Rough estimates beat no estimates", "Every token has a cost...") is motivational padding that adds no instruction Claude needs. This matches 'mostly efficient but includes some unnecessary explanation or could be tightened' — not 4 because that section is several lines of pure filler.

3 / 5

Actionability

Steps 2-5 provide concrete tables and output templates, but Step 1's scope analysis is comment-only pseudocode ("# Find affected files", "# Count existing lines") with no actual Glob/Grep commands despite allowed-tools declaring them, and the 'Superpowers estimate'/'Specialist Agent' comparison fields are undefined. This matches 'some concrete guidance but incomplete; pseudocode instead of executable code'.

3 / 5

Workflow Clarity

The five steps (Analyze Scope, Classify Complexity, Break Down Costs, Compare Models, Provide Recommendations) are clearly sequenced with concrete criteria at each stage. Not 5 because there are no validation or sanity-check checkpoints (e.g., cross-checking counted files/lines against the complexity table before classifying), though the read-only nature of the skill makes this a minor gap.

4 / 5

Progressive Disclosure

The skill is a single self-contained file with clear section headers and no nested or buried references, and at ~150 lines the inline placement of most content is appropriate. Not 5 only because the Cost Reference pricing tables (per-1M-token prices, typical task costs) are volatile reference data that could live in a separate one-level-deep reference file.

Description

61%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 has a strong, explicit 'Use when...' trigger with reasonably natural keywords, but it defines only when to use the skill and never states what the skill actually does. Adding an explicit capability statement and a few natural synonyms would raise both completeness and trigger coverage.

Suggestions

Add an explicit 'what' clause, e.g., 'Estimates token usage, cost, and complexity for a proposed feature... Use when planning a feature and you need a cost, time, or complexity estimate before committing to implementation.'

Include natural trigger variations users would say, such as 'estimate', 'budget', 'how much will this cost', 'how long', or 'effort', to broaden keyword coverage.

Tighten distinctiveness by leading with the skill's unique function (cost/token estimation) rather than the broad framing 'planning a feature', which overlaps with general planning skills.

DimensionReasoningScore

Specificity

The description names the domain and concrete deliverables ("understand token cost, time estimate, or complexity") but lists no concrete actions the skill performs. It matches the anchor 'names domain and 1-2 concrete actions, but not comprehensive' — not 4 because no capability verbs are given, and not 2 because three specific outputs are named rather than generic language.

3 / 5

Completeness

The 'when' is explicit ("Use when planning a feature... before committing to implementation") but the 'what' is only implied — the description never states what the skill does (e.g., 'Estimates token usage and cost...'). This sits between anchor 2 (only 'when' present without 'what') and anchor 4 (both explicit), so it lands at 3.

3 / 5

Trigger Term Quality

Phrases like "planning a feature", "token cost", "time estimate", and "complexity" are terms a user would naturally say when needing this skill, giving good keyword coverage. Not 5 because common synonyms and variations ("estimate", "budget", "effort", "how much", "how long") are missing.

4 / 5

Distinctiveness Conflict Risk

Token-cost/time/complexity estimation for feature planning is a mostly distinct niche with clear triggers. Minor overlap risk remains with general planning or architecture skills via the broad terms "planning a feature" and "complexity".
