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 | $0.00031 | $0.01620 |
| Opus 5 | $0.00015 | $0.00810 |
| Sonnet 5 | $0.00006 | $0.00324 |
| Haiku 4.5 | $0.00003 | $0.00162 |
Grade A, and why
plan-writing 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 2d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

84% identical to plan-writing — 103 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Plan Writing
Source: obra/superpowers
Overview
This skill provides a framework for breaking down work into clear, actionable tasks with verification criteria.
Task Breakdown Principles
1. Small, Focused Tasks
- Each task should take 2-5 minutes
- One clear outcome per task
- Independently verifiable
2. Clear Verification
- How do you know it's done?
- What can you check/test?
- What's the expected output?
3. Logical Ordering
- Dependencies identified
- Parallel work where possible
- Critical path highlighted
- Phase X: Verification is always LAST
4. Dynamic Naming in Project Root
- Plan files are saved as
{task-slug}.mdin the PROJECT ROOT - Name derived from task (e.g., "add auth" →
auth-feature.md) - NEVER inside
.claude/,docs/, or temp folders
Planning Principles (NOT Templates!)
🔴 NO fixed templates. Each plan is UNIQUE to the task.
Principle 1: Keep It SHORT
| ❌ Wrong | ✅ Right |
|---|---|
| 50 tasks with sub-sub-tasks | 5-10 clear tasks max |
| Every micro-step listed | Only actionable items |
| Verbose descriptions | One-line per task |
Rule: If plan is longer than 1 page, it's too long. Simplify.
Principle 2: Be SPECIFIC, Not Generic
| ❌ Wrong | ✅ Right |
|---|---|
| "Set up project" | "Run npx create-next-app" |
| "Add authentication" | "Install next-auth, create /api/auth/[...nextauth].ts" |
| "Style the UI" | "Add Tailwind classes to Header.tsx" |
Rule: Each task should have a clear, verifiable outcome.
Principle 3: Dynamic Content Based on Project Type
For NEW PROJECT:
- What tech stack? (decide first)
- What's the MVP? (minimal features)
- What's the file structure?
For FEATURE ADDITION:
- Which files are affected?
- What dependencies needed?
- How to verify it works?
For BUG FIX:
- What's the root cause?
- What file/line to change?
- How to test the fix?
Principle 4: Scripts Are Project-Specific
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.

plan-writing is a skill published in the GitHub repository bugrabilge/bilge-development-kit (10 stars, last pushed 4mo ago), licensed MIT. It adds 31 tokens to every session and 1,620 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 84% identical to plan-writing, differing in 103 lines, and is treated as a copy.
