project-skill-builder

Create project-specific Claude Code skills tailored to particular codebases, domains, or organizations. Workflow for analyzing project context, identifying skill opportunities, designing project-specific patterns, and building custom skills. Use when creating skills for specific projects, capturing project knowledge, building team-specific workflows, or developing domain-specific skill toolkits.

Quality

Content

42%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 presents a clearly sequenced 5-step meta-workflow but is almost entirely abstract: no executable guidance, concrete examples, or real validation procedures, and it depends on external skills that are not bundled or resolvable. It reads as a skeleton rather than operational instructions.

Suggestions

Add concrete, executable guidance to each step — e.g., specific commands or file-creation steps (what a 'project context document' should contain and where to write it, how to run the validation in Step 5), instead of bare labels like "Test: In actual project context".

Resolve or remove the dangling references to "development-workflow", "skill-researcher", and "skill-builder-generic" — either bundle them as reference files with clearly signaled paths or inline the relevant procedure from them.

Turn Step 5 into a real feedback loop: define what 'test in project context' means concretely (e.g., invoke the skill on a representative task, check the output against team standards, fix and retry) rather than just naming the validation.

DimensionReasoningScore

Conciseness

No explanations of concepts Claude already knows, but the body is padded with repetitive template scaffolding (per-step bold labels, "Output:" lines, horizontal rules, and a Quick Reference that restates the Overview). Could be tightened considerably.

3 / 5

Actionability

The body contains no code, commands, or concrete examples — it describes rather than instructs ("Use: development-workflow with project context", "Test: In actual project context"). There are high-level hints (named steps, outputs, example skill types) but the specific steps to execute are missing, matching the minimal-concrete-guidance anchor rather than anchor 1's total vagueness.

2 / 5

Workflow Clarity

The 5-step sequence is present and ordered, but validation checkpoints are missing or implicit — Step 5's "Validate: Effective for team/project" is a label with no actual procedure, and there is no feedback loop for iterating when validation fails.

3 / 5

Progressive Disclosure

Sections are well-organized with headers, but the body references "development-workflow" and "skill-researcher (for project patterns)" which have no corresponding files in this skill or explanations of where to find them, and the Quick Reference duplicates earlier content.

Description

83%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 strong: it clearly states what the skill does, enumerates the workflow actions, and provides an explicit multi-trigger 'Use when' clause. Minor room to improve on concrete deliverables and trigger synonyms.

DimensionReasoningScore

Specificity

Lists four named actions ("analyzing project context, identifying skill opportunities, designing project-specific patterns, and building custom skills"), matching the several-specific-actions anchor with minor gaps. Not 5 because the actions are high-level verbs without concrete techniques or deliverable specifics.

4 / 5

Completeness

Explicitly answers both what ("Create project-specific Claude Code skills... Workflow for analyzing... building custom skills") and when ("Use when creating skills for specific projects, capturing project knowledge, building team-specific workflows, or developing domain-specific skill toolkits") with concrete trigger phrases. Not 4 because the 'when' clause is fully explicit and specific.

5 / 5

Trigger Term Quality

Includes natural phrases users would say ("creating skills for specific projects", "capturing project knowledge", "team-specific workflows", "domain-specific skill toolkits"). Not 5 because common variations like "onboarding", "custom skills", or "automating team workflows" are missing.

4 / 5

Distinctiveness Conflict Risk

Scoped to project-specific skill creation with distinct triggers ("project knowledge", "team-specific workflows"), mostly distinct from generic skills. Not 5 because it could overlap with a generic skill-creation skill when the user just says "create a skill".
