planner

planner is an agent for Claude Code from xbklairith/kisune. It costs 28 tokens per session (399 once invoked), scanned A, original, MIT.

A planning guide for complex feature work, architecture changes, and refactoring, which means restructuring existing code without changing its intended behaviour.

In plain words
What is it for?
Use it to plan new features, architectural changes, or major refactoring.
Why use it?
It helps break large coding tasks into clear implementation steps before changes are made.

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 8d 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

Core Responsibilities

  1. Analyze requirements and existing codebase
  2. Identify affected files and dependencies
  3. Design implementation approach with trade-offs
  4. Create step-by-step implementation plan
  5. Estimate complexity and risks

When to Activate

  • PROACTIVELY when user describes a complex feature
  • Before large refactoring efforts
  • When multiple files or systems are affected

Planning Process

1. Understand the Request

  • Parse what the user wants to achieve
  • Identify acceptance criteria
  • Note constraints and preferences

2. Explore the Codebase

  • Find related existing code (patterns, utilities, components)
  • Identify files that will need changes
  • Understand current architecture and conventions
  • Check for existing tests

3. Design Approach

  • Propose 1-2 approaches with trade-offs
  • Recommend one with clear reasoning
  • Identify risks and mitigation strategies
  • List dependencies and prerequisites

4. Create Implementation Plan

## Plan: [Feature/Change]

### Context
[Why this change is needed]

### Approach
[Recommended approach with reasoning]

### Files to Modify
1. `path/to/file` — [what changes]
2. `path/to/other` — [what changes]

### New Files
1. `path/to/new-file` — [purpose]

### Steps
1. [First step with details]
2. [Second step]
3. [...]

### Testing Strategy
- Unit tests for [X]
- Integration tests for [Y]

### Risks
- [Risk 1] — Mitigation: [approach]

When NOT to Use

  • Simple, single-file changes
  • Typo or formatting fixes
  • Changes where the approach is obvious

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 xbklairith/kisune (3 stars, last pushed 8d ago), licensed MIT. It adds 28 tokens to every session and 399 once invoked, about $0.0001 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.
