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 | $0.00000 | $0.02121 |
| Opus 5.5 | $0.00000 | $0.00848 |
| Sonnet 5.5 | $0.00000 | $0.00424 |
| Haiku 4.5 | $0.00000 | $0.00212 |
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 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 — 180 lines — stays where its author put it; the contents beside it link to each section on GitHub.
name: milestone
description: Complete the current work as a milestone and start fresh for the next phase. Archives current idea files, including IMPL_ORCHESTRATION_PLAN.md when present, closes out affected worktrees with final local commits, archives repo-local .planning/PLAN.md files into milestone folders, writes a summary, and resets working files. Use when the user wants to mark a phase of work as done and move to the next.
Complete the current work on an idea as a milestone. Archive all current planning files (spec, research, assumptions, session, spikes, and IMPL_ORCHESTRATION_PLAN.md if present) into a milestone folder, close out affected implementation worktrees with final local commits, archive repo-local .planning/PLAN.md files into milestone folders inside each worktree, write a summary, and reset working files so the next phase starts clean — while preserving full historical context.
Instructions
When the user invokes /milestone, follow these steps:
1. Ensure Context is Loaded
If you haven't already loaded the current idea's files, read them now:
spec.mdsession.mdassumptions.mdresearch.mdIMPL_ORCHESTRATION_PLAN.md(if it exists)MILESTONES.md(if it exists — this means prior milestones already exist)
If no idea is currently active, trigger the /continue skill first to select one.
2. Draft the Milestone Summary
Before archiving, synthesize the current state into a milestone summary. Read session.md and spec.md to draft:
- Milestone name: A short descriptive name (e.g., "POC Validation", "Core API Implementation")
- Slug: URL-safe version (e.g., "poc-validation", "core-api")
- Summary: 2-4 sentences capturing what was accomplished
- Outcome: One of
completed,partial, orpivoted - Key outcomes: Bullet list of concrete deliverables or validations
- Key decisions: Carried from session.md
- What carries forward: What context/decisions/constraints feed into the next milestone
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.

milestone is a skill published in the GitHub repository nickmisasi/planner (5 stars, last pushed 6mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,121 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
