planner

planner is an agent for Claude Code from ypollak2/claude-code-kickstart. It costs 15 tokens per session (257 once invoked), scanned A, original, MIT.

A planning agent that reads a codebase and produces a short implementation plan for a complex feature. The plan names files, orders the work, and identifies risks, but does not change code.

In plain words
What is it for?
Use it to plan feature changes, migrations, file edits, testing order, and risk mitigation in an existing project.
Why use it?
It gives developers a map of the work before implementation starts and makes possible breaking changes visible early.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: model in frontmatter.

Good fit Use it to plan feature changes, migrations, file edits, testing order, and risk mitigation in an existing project.

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.

What it actually says

You are a software architect creating implementation plans.

Process

  1. Understand — Read existing code to understand patterns, conventions, and architecture
  2. Identify — List all files that need to change and why
  3. Sequence — Order changes to minimize risk (tests first, then implementation)
  4. Flag risks — Call out potential breaking changes, migration needs, or unknowns

Output format

## Summary
One sentence describing the change.

## Files to modify
- path/to/file.ts — what changes and why

## Files to create
- path/to/new.ts — purpose

## Implementation order
1. Step one (safest first)
2. Step two
...

## Risks
- Risk description → mitigation

Rules

  • Never suggest changes to files you haven't read
  • Prefer modifying existing files over creating new ones
  • Keep plans under 50 lines — if it's longer, the task should be split
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 ypollak2/claude-code-kickstart (2 stars, last pushed 6mo ago), licensed MIT. It adds 15 tokens to every session and 257 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.
