milestone

milestone is a skill for Claude Code from lwalden/AIAgentMinder. It costs 6 tokens per session (1,261 once invoked), scanned A, original, MIT.

A project health assessment that reviews scope, progress, complexity, and known technical debt. Technical debt means work left behind that may make future changes harder.

In plain words
What is it for?
Use it at sprint boundaries, phase changes, or whenever you need to assess project health. It checks roadmap status, architecture decisions, sprint progress, task states, recent git history, file counts, and large source files.
Why use it?
It gives a solo developer a periodic view of whether the project is still on track. It brings roadmap, decisions, sprint records, task states, recent commits, and project size into one review.

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

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.

The opening of the file, as written. The whole thing — 121 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/aiagentminder:milestone - Project Health Assessment

Run a milestone health check to assess whether the project is on track. This is the "project standup" that solo developers don't have — a periodic review of scope, progress, complexity, and known debt.

Run this at sprint boundaries, at phase transitions, or any time you want a clear picture of where the project stands.


Step 1: Gather Context

Read the following:

  1. docs/strategy-roadmap.md — current phase, MVP features, out-of-scope items, phase timeline
  2. DECISIONS.md — original stack and architecture decisions; also read the ## Known Debt section if present
  3. SPRINT.md — current sprint status (if active); archived sprint lines for sprint sizing data
  4. Use TaskList to get current task states
  5. Recent git log: git log --oneline -20 — what has been merged recently
  6. File count and largest files:
    # Cross-platform file count (excluding .git)
    find . -type f -not -path './.git/*' | wc -l
    # Largest source files
    find . -name "*.ts" -o -name "*.js" -o -name "*.py" -o -name "*.go" -o -name "*.rs" | xargs wc -l 2>/dev/null | sort -rn | head -5
    
    (adjust extensions for the project stack; on Windows use Get-ChildItem -Recurse -File | Measure-Object)
  7. Dependencies: read package.json, pyproject.toml, go.mod, Cargo.toml, or equivalent

Step 2: Assess Each Dimension

A. Phase Progress

  • Which phase is declared in the roadmap?
  • What MVP features are complete (have merged PRs), in progress, or not started?
  • Is there non-MVP work that was done while MVP features remain unstarted? (scope drift signal)
  • What percentage of Phase 1 features are done?

B. Timeline Health

  • What is the declared target date or phase duration from the roadmap?
  • Based on the pace of recent merged work, is the project on track?
  • Are there open blockers or unresolved questions that threaten the timeline?

C. Scope Drift

  • Were any features added to the sprint or codebase that aren't in the roadmap?
  • Did any approved issue expand significantly beyond its original scope?
  • Check SPRINT.md scope additions if present.

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.
