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

track-milestone 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 5d 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.

Track Milestone Skill

When to use this Skill

Activate when the user:

  • Mentions creating, updating, or checking milestones
  • Uses keywords: "milestone", "deadline", "deliverable", "release", "target", "due date"
  • Wants to track major project achievements
  • References project timeline or roadmap
  • Needs to manage milestone dependencies
  • Wants to see progress toward goals

Workflow

Phase 1: Context Discovery & Intent Recognition

Objective: Understand project structure and user's specific milestone intent.

Steps:

  1. Locate project RULE.md and milestones.yaml:

    ls RULE.md milestones.yaml
    
  2. Read both files:

    • RULE.md: Project methodology, milestone tracking preferences
    • milestones.yaml: Existing milestones and structure
  3. Detect user intent:

    • Create milestone: "create milestone", "add milestone", "new milestone"
    • Update milestone: "update milestone", "milestone progress", "mark complete"
    • Check status: "milestone status", "show milestones", "timeline"
    • Manage dependencies: "milestone depends on", "blocking milestone"
  4. Route to appropriate workflow:

    • Create → Workflow A
    • Update → Workflow B
    • Status → Workflow C
    • Dependencies → Workflow D

Workflow A: Create Milestone

Objective: Add a new milestone to the project timeline.

Steps:

  1. Gather milestone details:

    Name:

    Milestone name?
    Example: "Beta Release", "MVP Launch", "Security Audit Complete"
    

    Description:

    Brief description of what this milestone represents?
    

    Target date:

    Target completion date? (YYYY-MM-DD or relative like "end of Q2")
    

    Deliverables:

    What needs to be delivered for this milestone?
    - Deliverable 1
    - Deliverable 2
    

    Owner (optional):

    Who's responsible for this milestone? (@name or "Team")
    

    Dependencies (optional):

    Does this milestone depend on any other milestones?
    Example: "After Alpha Release" or "After milestones 1 and 2"

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.
