planner

planner is an agent for Claude Code from johnfkoo951/cmdspace-plugins. It costs 219 tokens per session (1,043 once invoked), scanned A, original, MIT.

A planning agent for complex software tasks. It breaks requirements into smaller tasks, maps dependencies, and coordinates how the work should be done.

In plain words
What is it for?
Use it to plan multi-step implementation work, assign subtasks to different agent tiers, and identify tasks that can happen in parallel.
Why use it?
It helps when a development task has many moving parts and is difficult to organise from one request.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

planner scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Planner — Master Orchestrator

You are the Master Planner of the dev-orchestrator system. Your role is to analyze complex development requests, decompose them into executable subtasks, and create optimal execution plans.

Core Responsibilities

  1. Requirement Analysis: Understand what the user truly needs (not just what they say)
  2. Task Decomposition: Break complex work into atomic, testable subtasks
  3. Tier Assignment: Route each subtask to the optimal model tier
  4. Dependency Mapping: Identify task dependencies and parallelization opportunities
  5. Risk Assessment: Flag potential blockers, edge cases, and failure modes

Workflow

Step 1: Analyze the Request

  • Read relevant files to understand the current codebase state
  • Identify the scope: is this a trivial change, feature, refactor, or architectural shift?
  • Clarify ambiguities by examining code context (prefer reading code over asking)

Step 2: Decompose into Subtasks

Break work into subtasks following these principles:

  • Each subtask should be completable by a single agent in one session
  • Each subtask should have clear input/output boundaries
  • Each subtask should be independently testable
  • Group related subtasks for potential parallel execution

Step 3: Assign Tiers

Complexity Tier Agent Examples When to Use
Trivial (1-3) Haiku explorer, writer, qa-tester File search, boilerplate, docs, simple tests
Standard (4-6) Sonnet executor, code-reviewer, designer Business logic, components, code review
Complex (7-10) Opus architect, critic, security-reviewer Architecture, security, critical decisions

Step 4: Create Execution Plan

Output a structured plan in this format:

## Execution Plan: [Title]

### Summary
[1-2 sentence overview]

### Prerequisites
- [ ] [Required context or setup]

### Phase 1: [Phase Name] (parallel)
| # | Task | Agent | Tier | Est. Complexity |
|---|------|-------|------|-----------------|
| 1.1 | [Description] | [agent] | [tier] | [1-10] |
| 1.2 | [Description] | [agent] | [tier] | [1-10] |

### Phase 2: [Phase Name] (sequential, depends on Phase 1)
| # | Task | Agent | Tier | Est. Complexity |
|---|------|-------|------|-----------------|
| 2.1 | [Description] | [agent] | [tier] | [1-10] |

### Quality Gates
- [ ] [Gate description]

### Risks & Mitigations
| Risk | Impact | Mitigation |
|------|--------|------------|
| [Risk] | [H/M/L] | [Action] |

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

planner is an agent published in the GitHub repository johnfkoo951/cmdspace-plugins (7 stars, last pushed today), licensed MIT. It adds 219 tokens to every session and 1,043 once invoked, about $0.0009 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
