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 | $0.00011 | $0.01237 |
| Opus 5.5 | $0.00004 | $0.00495 |
| Sonnet 5.5 | $0.00002 | $0.00247 |
| Haiku 4.5 | $0.00001 | $0.00124 |
Grade A, and why
update-feature 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.
How it starts
The opening of the file, as written. The whole thing — 191 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Update Feature Planning Document
This command updates feature plans for small to medium changes. For larger changes, use /plan-feature to recreate the plan.
Workflow
STEP 1: Analyze Change
Read planning file: {PLANNING_FILE} Analyze change: {CHANGE_DESCRIPTION}
Determine:
- What sections need updating?
- Is this minor (add feature) or major (change approach)?
- Any questions to clarify?
If unclear: Ask 1-4 questions, WAIT for response. If clear: Proceed to Step 2.
STEP 2: Propose Updates
Present a concise proposal:
# 📋 Update Proposal: [Brief title]
## Summary
[2-3 sentences explaining the change]
## Changes to Planning Document
### Requirements (if affected)
- **Add:** [New requirement]
- **Modify:** [What changes]
- **Remove:** [What's removed and why]
### Technical Design (if affected)
**Database:** [Schema changes if any]
**API:** [Endpoint changes if any]
**UI:** [Component changes if any]
### Implementation Progress Table
**New tasks to add:**
- Phase X, Task X.Y: [Description] - ⏸️ Pending
**Tasks to modify:**
- Phase Y, Task Y.Z: [Old description] → [New description]
(Keep current status: ✅/🔄/⏸️)
### Testing & Acceptance Criteria
[What needs to be updated]
## Impact Summary
- **Effort:** +[X] hours/days
- **Breaking changes:** [Yes/No - explain]
- **New dependencies:** [List if any]
---
**Review and approve:**
Type "approved" to update the planning document and proceed with implementation.
Type "feedback: [your comments]" to revise this proposal.
Type "cancel" to abort.
STOP and WAIT for user response.
STEP 3: Handle Response
If "approved":
- Update the planning document with all approved changes
- Preserve Implementation Progress table:
- Keep ✅ Complete tasks unchanged
- Keep 🔄 In Progress tasks unchanged
- Add new tasks as ⏸️ Pending with "NEW" label
- Update modified tasks with "MODIFIED" label
- Add update metadata:
*Last Updated: [Date] - [Change summary]* - Proceed to STEP 4
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.
