planner

Create comprehensive, phased implementation plans with sprints and atomic tasks. Use when user says: "make a plan", "create a plan", "plan this out", "plan the implementation", "help me plan", "design a plan", "draft a plan", "write a plan", "outline the steps", "break this down into tasks", "what's the plan for", or any similar planning request. Also triggers on explicit "/planner" or "/plan" commands.

Quality

Content

85%

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 well-sequenced, actionable planning workflow with strong validation checkpoints and a concrete template. Its only real weakness is mild verbosity in the Phase 1 question-category list, plus a minor duplicate "Phase 3" label that does not break the sequence.

Suggestions

Tighten the Phase 1 suggested-question list: drop the filler "Ask any helpful question" entry and collapse redundant categories so the list earns every token.

Fix the duplicate phase numbering — both "Phase 3: Create Plan" and "Phase 3: Save" are labeled Phase 3; renumber Save as Phase 4 and Gotchas as Phase 5 to keep the sequence unambiguous.

Consider moving the full Plan Template block into a references file (e.g. references/plan-template.md) referenced one level deep, keeping SKILL.md as a leaner overview.

DimensionReasoningScore

Conciseness

Mostly lean and directive, but the 10-item suggested-question category list in Phase 1 (including filler like "Ask any helpful question") could be tightened; it does not over-explain concepts Claude already knows.

2 / 3

Actionability

Concrete, executable guidance throughout: explicit sprint/task requirements, a Good/Bad task contrast ("Add Google OAuth config to env variables", "Create OAuth callback route in src/routes/auth.ts"), and a copy-paste-ready plan template.

3 / 3

Workflow Clarity

Clear phase sequence (Research → Clarify → Retrieve Docs → Create → Save → Gotchas) with explicit validation checkpoints: demo/verification checklists, a stop-and-ask feedback loop, and the hard guardrail "Do NOT implement - only create the plan".

3 / 3

Progressive Disclosure

No bundle files exist and none are needed; the body is well-organized into clearly headed sections (Process, Plan Template, Important) with no nested references and no monolithic wall of text.

Description

100%

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, well-formed description: it states concrete capabilities in third person and provides an explicit, broad set of natural trigger terms and commands. Both the what and when are clearly answered with minimal fluff.

DimensionReasoningScore

Specificity

"Create comprehensive, phased implementation plans with sprints and atomic tasks" names multiple concrete actions (planning, sprinting, atomic tasking) rather than vague language.

3 / 3

Completeness

Explicitly answers both what it does and when to use it via a clear "Use when user says..." clause with explicit triggers, satisfying the top anchor.

3 / 3

Trigger Term Quality

Lists natural phrases users say ("make a plan", "plan this out", "break this down into tasks", "what's the plan for") plus explicit /planner and /plan commands — strong coverage.

3 / 3

Distinctiveness Conflict Risk

The planning niche is distinct and the triggers ("make a plan", /planner, /plan) are specific enough to be unlikely to fire for unrelated skills.
