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 | $0.00016 | $0.01153 |
| Opus 5 | $0.00008 | $0.00576 |
| Sonnet 5 | $0.00003 | $0.00231 |
| Haiku 4.5 | $0.00002 | $0.00115 |
Grade A, and why
planning 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 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.
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.
How it starts
The opening of the file, as written. The whole thing — 161 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Planning with Trekker
Before starting any multi-step task, break it down in Trekker FIRST.
This ensures:
- Work is tracked and resumable
- Dependencies are explicit
- Progress is visible across sessions
- Context survives resets
When to Plan in Trekker
Use this workflow when:
- Task has 3+ steps
- Work spans multiple files
- Implementation requires specific order
- Task might take more than one session
- User asks for a feature/fix that isn't trivial
Planning Workflow
Step 1: Search for Related Work
# ALWAYS search first - previous work may exist trekker search "<what you're about to do>"
Step 2: Create Epic (if substantial)
For features with multiple tasks:
trekker epic create -t "Feature: User Authentication" \
-d "JWT-based auth with login, registration, and session management"
Step 3: Break Down into Tasks
Create atomic, completable tasks:
# Each task should be independently completable
trekker task create -t "Create User model with email/password" \
-d "Define User schema with bcrypt password hashing" \
-e EPIC-1 -p 1
trekker task create -t "Implement login endpoint" \
-d "POST /api/auth/login - validate credentials, return JWT" \
-e EPIC-1 -p 1
trekker task create -t "Implement registration endpoint" \
-d "POST /api/auth/register - create user, hash password" \
-e EPIC-1 -p 1
Step 4: Set Dependencies
Make execution order explicit:
# Login depends on User model
trekker dep add TREK-2 TREK-1
# Registration depends on User model
trekker dep add TREK-3 TREK-1
Step 5: Mirror to TodoWrite
After Trekker is set up, create matching todos:
TaskCreate for each Trekker task
Set blockedBy relationships matching Trekker deps
Task Quality Rules
Good Task Titles
BAD: "Fix bug"
GOOD: "Fix null pointer in UserService.getById when user not found"
BAD: "Add feature"
GOOD: "Add email validation to registration form"
Good Descriptions
Every task MUST answer:
- What: Specific action to take
- Why: Problem being solved
- Where: Files/components involved
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.

planning is a skill published in the GitHub repository obsfx/trekker-claude-code (4 stars, last pushed 4mo ago), licensed MIT. It adds 16 tokens to every session and 1,153 once invoked, about $0.0001 per session on Opus 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.

clarify
This skill should be used when user appears confused, frustrated, or shows misalignment between expectations and reality. Triggers on phrases like "I don't understand", "this doesn't make sense", "confused", "wait, shouldn't it...", "why is this happening", "I thought X did Y", contradictory statements, or frustration…
md-copy
Format final answer as markdown and copy to clipboard. Use when user says "copy as markdown", "md copy", "copy formatted", "clipboard", or wants the session's final answer formatted and copied.
txt-copy
Copy generated text content to clipboard. Use when user asks to "copy this", "copy to clipboard", "save to clipboard", or after creating emails, messages, letters, or other text content that needs to be shared.
