Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00076 | $0.03975 |
| Opus 5 | $0.00038 | $0.01988 |
| Sonnet 5 | $0.00015 | $0.00795 |
| Haiku 4.5 | $0.00008 | $0.00398 |
Grade B, and why
planning-mode scanned grade B 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 5d 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
| Claude Code | `~/.claude/settings.json` | _(none — default)_ | How it starts
The opening of the file, as written. The whole thing — 361 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Usage
/planning-mode— Enable planning mode, then prompt for a topic/planning-mode <topic>— Enable planning mode and start planning/planning-mode continue— List existing plan folders and resume one/planning-mode off— Disable planning mode
Configuration
Planning mode works best with automated reminders, but it can still run with manual planning-doc updates when hook support is unavailable.
| Tool | Hook config location / equivalent | Script format argument |
|---|---|---|
| Claude Code | ~/.claude/settings.json |
(none — default) |
| Copilot | ~/.copilot/hooks.json |
copilot |
| Pi | Bundled active-mode extension in .pi/agent/extensions/active-mode/ |
(extension-driven) |
Claude Code and Copilot support the bundled PostToolUse and SessionStart hook scripts directly. Pi does not use the same standalone hook configuration files in this repository's starter config. Instead, this starter config now ships a Pi-native active-mode extension that reads .ai/.active-mode, clears stale flags on fresh session start, injects reminder context before LLM calls, and shows mode status in the UI. If that extension is not installed, fall back to manual planning-doc updates.
If you cannot determine which tool you are, ask the user.
Planning files
Use persistent markdown files as your "working memory on disk." Context windows are volatile and limited; anything important gets written to disk.
- For any plan, you must create the following files in the plan folder:
- plan.md — Track work breakdown and progress
- questions.md — Track your questions and the user's responses and vice versa
- findings.md — Store research and discoveries
- For multi-phase plans, you must also create:
- progress.md — Session log and test results
- Before creating the planning files, you must read the starting templates in
./templates/ - You must use the starting templates when creating or updating planning files to guide the structure and content of these files
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 5d ago First seen · 361 lines · 76 tokens per session scan B 211d0347f0d3
planning-mode is a skill published in the GitHub repository kimgoetzke/coding-agent-configs (2 stars, last pushed 16d ago), licensed MIT. It adds 76 tokens to every session and 3,975 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
