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 | $0.00016 | $0.01153 |
| Opus 5.5 | $0.00006 | $0.00461 |
| Sonnet 5.5 | $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 1mo 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.
This is a copy
100% identical to planning — 0 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.
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 yesterday), licensed MIT. It adds 16 tokens to every session and 1,153 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to planning, differing in 0 lines, and is treated as a copy.
Other skills, from other repositories
flow-next-flow
Use first in a Flow-Next repo for a spec id, change, bug, issue, slow code or metric, cleanup, design fork, dump to explain, repeated mistake, prompt change, what could break, what next. No quick asks.
flow-next-tracker-sync
Project a flow-next spec to a tracker issue (Linear, GitHub, GitLab, Jira) and reconcile two-way. Use when asked to sync to a tracker. NOT plan-sync.
flow-next-plan
Plan a feature into a flow-next spec with tasks in .flow/. Use when asked to plan, spec out, or break down work (fn-N ids).
flow-next
Manage .flow/ tasks and specs. Use for show or list tasks, task status, what is ready, show fn-N. NOT for planning or executing (use the plan and work skills).
backlog
Read, work, and maintain a Git repo's deferred-work items in docs/backlog/, one file per item. Use when the user says "backlog", "check backlog", "what's on my backlog", "work the backlog", "address the backlog", "add to backlog", "clean up backlog", or when a review or task produced items that are real but not being…
execute-round
Use when a planned round handoff exists and needs to be implemented end-to-end via the 4-commit chain (entry-admin → BA design → dev body with inline CR + SE → state refresh + self-audit). Dispatches ba-designer / developer / cr-reviewer / se-contract sequentially.
