task-development

Break down skill development into concrete tasks with time estimates, dependencies, and validation criteria. Creates actionable task lists, identifies blockers, estimates effort, and sequences work optimally. Use when planning skill implementation, managing complex builds, or coordinating parallel work.

Quality

Content

63%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 skill is highly actionable — concrete commands, templates, output formats, and three worked examples — with a clearly sequenced six-step workflow and real, well-signaled bundle files. Its main problem is bloat: Steps 4–6 duplicate ~400 lines of reference-file content inline (material Claude largely already knows), and the body re-summarizes itself in a final Quick Reference that even contradicts the six-step workflow. Converting the inline technique detail into pointers to the existing reference files would fix both the conciseness and progressive-disclosure scores.

Suggestions

Replace the inline Technique 1–5 detail in Step 4 with a 5-line summary table and point to references/estimation-techniques.md, which already covers the same methods comprehensively.

Collapse the three dependency-type subsections in Step 5 to their indicator lists and move the detail to references/dependency-management.md.

Fix or remove the "Quick Reference: The 5-Step Task Breakdown Process" section, which contradicts the six-step workflow and re-states content already covered above.

DimensionReasoningScore

Conciseness

The ~1,270-line body is heavily padded: Steps 4–6 inline ~130 lines each of estimation techniques, dependency types, and sequencing strategies — much of it concepts Claude already knows (the three-point formula, "quick wins build momentum", what a hard dependency is) — that duplicate content already in the reference files, and the final "Quick Reference" section then repeats the entire workflow again. It is not a 1 because genuine domain-specific content (output formats, granularity specs, worked examples) is present, and not a 3 because the padding and duplication are extensive rather than incidental.

2 / 5

Actionability

Guidance is fully executable: copy-paste-ready commands ("python scripts/break-down-tasks.py skill-plan.md --output tasks.md"), a complete task-list output template, a per-task template with validation fields, and three worked examples spanning simple, medium, and complex skills. It is not a 4 because the common cases are concretely covered end-to-end.

5 / 5

Workflow Clarity

The six-step workflow is clearly sequenced with Objective/Process/Output per step, milestones, a validation component, a success-criteria section, and a checklist (Step 4's "Validate Total" against the plan estimate is an explicit checkpoint). It is not a 5 because the "Quick Reference" section presents a contradictory "5-Step Task Breakdown Process" with different step names than the 6-step workflow, and error-recovery feedback loops are implicit. Not a 3 because validation checkpoints are explicit and well-placed.

4 / 5

Progressive Disclosure

The three reference files and script exist, are one level deep, and are well signaled via "See Also" links and a References section — but the deep material in Steps 4–6 (estimation techniques, dependency types, sequencing strategies) is inlined even though dedicated reference files exist for exactly those topics. It is not a 4 because the inlining is extensive rather than a minor organization gap, and not a 2 because references are clearly signaled and the overview/reference split is structurally present.

Description

88%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.

A strong description: it explicitly states both what the skill does and when to use it, in third person, with multiple concrete actions and a clear "Use when..." clause. The main weakness is trigger coverage — natural phrasings like "task list", "break down into tasks", and "time estimates" are absent, leaving slight overlap risk with generic planning skills.

DimensionReasoningScore

Specificity

The description lists multiple concrete actions — "Creates actionable task lists, identifies blockers, estimates effort, and sequences work optimally" — covering breakdown, estimation, dependency identification, and sequencing comprehensively. It is not a 4 because coverage spans the full set of the skill's functions rather than leaving minor gaps.

5 / 5

Completeness

Both questions are explicitly answered: the "what" ("Creates actionable task lists, identifies blockers, estimates effort, and sequences work optimally") and the "when" ("Use when planning skill implementation, managing complex builds, or coordinating parallel work") with concrete trigger phrases. It is not a 4 because the "when" clause is explicit and specific rather than merely serviceable.

5 / 5

Trigger Term Quality

"Use when planning skill implementation, managing complex builds, or coordinating parallel work" provides good natural trigger phrases. It is not a 5 because common variations a user would actually say — "task list", "break down into tasks", "time estimates", "project schedule" — are missing.

4 / 5

Distinctiveness Conflict Risk

The description carves out a fairly distinct niche (task breakdown for skill development), but triggers like "planning skill implementation" and "managing complex builds" overlap with general planning or project-management skills. It is not a 5 due to this minor overlap risk with closely related skills, and not a 3 because the domain framing is concrete.
