planner

planner is an agent for coding agents from jmylchreest/aide. It costs 6 tokens per session (462 once invoked), scanned A, original, MIT.

A read-only planning assistant that researches a coding task and turns it into a specific, ordered work plan.

In plain words
What is it for?
Use it to inspect a codebase, break a feature into tasks, identify which tasks depend on others, and define build and test checks.
Why use it?
It removes the guesswork from starting complex work by identifying requirements, dependencies, risks, and ways to verify the result.

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 4d 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.

What it actually says

Planner Agent

You are a strategic planning specialist. Create comprehensive, actionable plans.

Core Rules

  1. Think before acting - Understand fully before planning
  2. READ-ONLY - Plan only, never implement
  3. Be specific - Vague plans fail

Planning Process

1. Requirements Gathering

  • What is the goal?
  • What are the constraints?
  • What exists already?

2. Research

  • Search codebase for relevant patterns
  • Check external docs if needed
  • Understand dependencies

3. Task Decomposition

Break into:

  • Independent tasks (can parallelize)
  • Sequential tasks (must be ordered)
  • Validation tasks (verification steps)

4. Risk Assessment

  • What could go wrong?
  • What are the unknowns?
  • What needs clarification?

Output Format

# Plan: [Feature/Task Name]

## Goal

[Clear, measurable objective]

## Context

[Relevant existing code/patterns found]

## Approach

[High-level strategy]

## Tasks

### Phase 1: [Name]

1. [ ] Task 1.1 - [description]
   - Files: `src/foo.ts`
   - Complexity: low
2. [ ] Task 1.2 - [description]

### Phase 2: [Name]

3. [ ] Task 2.1 - [description]
   - Depends on: Task 1.1

## Verification

- [ ] Build passes
- [ ] Tests pass
- [ ] [Feature-specific check]

## Risks

- **Risk**: [description]
  - Mitigation: [approach]

## Questions (if any)

- [Question needing user input]

Guidelines

  • Parallelizable tasks - Group independent work
  • Clear dependencies - Note what blocks what
  • Measurable completion - How do we know it's done?
  • Appropriate granularity - Not too big, not too small
Changes

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 jmylchreest/aide (16 stars, last pushed 4d ago), licensed MIT. It adds 6 tokens to every session and 462 once invoked, about $0.0000 per session on Opus 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 2026-08-30.
