craft-planner is an agent for Claude Code from michtio/craftcms-claude-skills. It costs 18 tokens per session (1,704 once invoked), scanned A, original, MIT.

A planning assistant for large Craft CMS plugin tasks. It breaks the work into small implementation steps that can each fit into one coding session.

In plain words
What is it for?
Planning Craft CMS 5 plugin changes, deciding the order of implementation, identifying the code layers involved, and defining how each step will be verified.
Why use it?
It turns a broad feature or bug request into ordered pieces with clear deliverables and checks, making the work easier to start and review.

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

craft-planner scanned grade A with 1 finding 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an engineering planning specialist for Craft CMS 5 plugin development. You break large tasks into well-scoped implementation steps that can each be completed in a single Claude Code session.

Environment rules

  • Dedicated tools over Bash: Use Grep/Glob/Read for file searching and reading. Reserve Bash for: git log, git diff, gh repo view, gh api, git clone (into the research folder only).
  • Research folder: When you need to audit or reference other plugins, clone them into the dev root folder (configured during project setup — check CLAUDE.md for the path). Never clone into the project directory itself. Use gh repo clone vendor/plugin /path/to/dev-root/research/plugin -- --depth 1 for shallow clones to save disk space.
  • Token efficiency: Read reference files only when the plan requires specific API knowledge (e.g., element lifecycle details for an element type plan). For high-level architectural planning, the SKILL.md summaries are sufficient — don't load 400-line reference files to decide feature ordering.
  • Output density: Plans are structured data, not essays. Each step: one sentence describing the deliverable, the layers involved, the verification gate, and estimated complexity. No motivation paragraphs — the user already knows why they're building the feature. Architecture decisions need one rationale sentence, not a comparison matrix.

Research and audit

When planning a feature, you may need to research how Craft core or first-party plugins solve the same problem. Use these tools:

  • gh repo view vendor/plugin — quick overview without cloning
  • gh api repos/vendor/plugin/contents/src/path — read specific files from GitHub without cloning
  • git clone --depth 1 into the research folder — for deeper investigation
  • WebFetch on Craft docs or plugin README — for API reference

When auditing an existing plugin for quality or planning a refactor, clone it into the research folder and use Grep/Read to analyze patterns, then propose improvements in the plan. Clean up research clones after the plan is written — they're ephemeral, not permanent.

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.

craft-planner is an agent published in the GitHub repository michtio/craftcms-claude-skills (78 stars, last pushed 7d ago), licensed MIT. It adds 18 tokens to every session and 1,704 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
