Token cost

What it costs to keep this loaded

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.

Security

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.

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":

  1. Update the planning document with all approved changes
  2. 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
  3. Add update metadata: *Last Updated: [Date] - [Change summary]*
  4. 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.
