Conciseness

The body is largely efficient — compact key principles, a bad-vs-good example, and a template — with only minor trimmable content: the am-will/codex-skills attribution appears twice ("Source: Based on..." and "Both are based on am-will's codex-skills prompts") and the sprint/task principles partially restate what the template already encodes. It is not a 5 because of this duplication, and not a 3 because no section is genuinely padded or explains concepts Claude already knows.

Actionability

The plan template is concrete and copy-paste ready, but the actual planning process — the skill's core instruction — is delegated entirely to `prompts/planner.md` ("Load the full planner prompt... and follow its process"), which is not present in the bundle, and the Phase 0–4 list gives only one-line hints ("Research & understand the codebase"). This matches 'some concrete guidance but incomplete; missing key details' rather than a 4, whose gaps would be minor.

Workflow Clarity

The five phases are clearly sequenced and Phase 3 ("Subagent review of the plan") names a checkpoint, but there is no feedback loop specifying what to do when the review finds problems, and the per-phase detail needed to actually execute the sequence lives in the missing prompt file. This sits at 'sequence present but checkpoints missing or implicit', not a 4, which would require most checkpoints with explicit validation handling.

Progressive Disclosure

References to `prompts/planner.md` and `prompts/parallel-task.md` are clearly signaled and one level deep, but the bundle contains no prompts/ directory, so both references are dangling and the skill is unnavigable as shipped; the ~45-line plan template is also inlined where the referenced prompt file would naturally hold it. Structure exists (headed sections, a Files list), but the broken references and inline bulk keep this at 'some structure but could be better organized' rather than a 4.

Specificity

"Create structured plans for multi-task projects" names the domain plus one concrete action (create structured plans), matching the '1-2 concrete actions, but not comprehensive' anchor; it does not list several specific actions (e.g., decompose into sprints, define dependencies, draft acceptance criteria) that would warrant a 4.

Completeness

It clearly answers both questions: the "what" is "Create structured plans for multi-task projects that can be executed by the task-orchestrator skill" and the "when" is an explicit "Use when breaking down complex work into parallel/sequential tasks with dependencies" clause with concrete trigger conditions, mirroring the score-5 example; it is not a 4 because the when-clause is already specific rather than improvable.

Trigger Term Quality

Natural phrases like "structured plans", "breaking down complex work", "parallel/sequential tasks", and "dependencies" are terms users would plausibly say when needing this skill; common variations such as "roadmap", "sprint", "milestone", or "project plan" are missing, keeping it below a 5.

Distinctiveness Conflict Risk

The pairing with the task-orchestrator skill and the parallel/dependencies framing give it a mostly distinct niche with only minor overlap risk against generic planning or task-management skills; it is not a 5 because "create plans for complex work" could still collide with other project-planning skills.
