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 | $0.00012 | $0.00583 |
| Opus 5.5 | $0.00005 | $0.00233 |
| Sonnet 5.5 | $0.00002 | $0.00117 |
| Haiku 4.5 | $0.00001 | $0.00058 |
Grade A, and why
init 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 2mo 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.

INITIALIZATION MODE ACTIVATED
You are now in INIT (initialization) phase.
Purpose
Initialize a new task by analyzing the project and determining the appropriate workflow.
Your Tasks
-
Analyze the Project
- Scan project structure
- Identify tech stack and patterns
- Note existing conventions
- Check for existing context files (
tmp/prd.md,tmp/design.md,tmp/project-brief.md,tmp/tasks.md,tmp/active-context.md)
-
Understand the Request
- What is the user asking for?
- What is the scope?
- Are there ambiguities to clarify?
-
Determine Complexity Level
Level Type Characteristics Workflow 1 Quick Fix Single file, obvious change, < 30 min /build->/review2 Simple Task Few files, clear scope, < 2 hours /plan->/qa->/build->/review3 Feature Multiple files, design decisions needed /plan->/creative->/qa->/build->/review4 Complex Architectural, cross-cutting, multi-day /plan->/creative->/qa->/build->/review->/archive -
Set Up Context
- Create/update
tmp/tasks.mdif needed - Create/update
tmp/active-context.mdif needed - Note any existing progress
- Create/update
-
Route to Next Command
- Level 1: Recommend
/build - Level 2-4: Recommend
/plan
- Level 1: Recommend
Output Format
## Task Initialization
### Project Analysis
- **Tech Stack:** [languages, frameworks]
- **Structure:** [monorepo, single app, etc.]
- **Conventions:** [patterns observed]
### Request Understanding
- **Task:** [what user wants]
- **Scope:** [files/modules affected]
- **Ambiguities:** [questions if any]
### Complexity Assessment
**Level: [1-4]**
**Reasoning:**
- [Why this level]
- [Key factors]
### Recommended Workflow
[workflow path, e.g., /plan -> /creative -> /qa -> /build -> /review]
### Next Step
Run `/plan` to begin planning (or `/build` for Level 1 tasks).
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.
- 2mo ago First seen · 81 lines · 12 tokens per session scan A 72e24c2717b2
init is a command published in the GitHub repository d-padmanabhan/agent-engineering-handbook (20 stars, last pushed yesterday), licensed MIT. It adds 12 tokens to every session and 583 once invoked, about $0.0000 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 2026-08-30.
