How do I install the Planner skill?

Run npx skillmds add majiayu000/planner-3 in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

Is Planner safe to use?

This skill has not completed SkillMD's automated safety review yet. Capability flags: docs only. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with Planner?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Is Planner free to use?

Yes. Installing skills from SkillMD is free, and the skill stays under its author's original license.

Planner Skill

Two-phase workflow: planning (create plans) and execution (implement plans).

Activation

When this skill activates, IMMEDIATELY invoke the corresponding script. The script IS the workflow.

Mode	Intent	Command
planning	"plan", "design", "architect"	`python3 scripts/planner.py --phase planning --step 1 --total-steps 4`
review	"review plan" (after plan written)	`python3 scripts/planner.py --phase review --step 1 --total-steps 3`
execution	"execute", "implement", "run plan"	`python3 scripts/executor.py --step 1 --total-steps 7`

When to Use

Use when task has:

Multiple milestones with dependencies
Architectural decisions requiring documentation
Complexity benefiting from forced reflection pauses

Skip when task is:

Single-step with obvious implementation
Quick fix or minor change
Already well-specified by user

Resources

Resource	Contents	Read When
`resources/diff-format.md`	Unified diff specification	Writing code changes in milestones
`resources/temporal-contamination.md`	Comment hygiene heuristics	Writing comments in code snippets
`resources/default-conventions.md`	Structural conventions	Making decisions without explicit user guidance
`resources/plan-format.md`	Plan template structure	Completing planning phase (injected by script)

Workflow Summary

Planning phase: 4+ steps:

Context Discovery - explore, gather requirements
Approach Generation - generate options with tradeoffs
Assumption Surfacing - user confirmation of choices
Approach Selection & Milestones - decide, write milestones

Review phase: 3 steps:

Parallel QR (completeness + code)
TW documentation scrub
QR-Docs validation

Execution phase: 7 steps:

Execution planning
Reconciliation (conditional)
Milestone execution via execute-milestone.py
Post-implementation QR
QR issue resolution (conditional)
Documentation
Retrospective

Scripts inject step-specific guidance. Invoke and follow output.
