plan_milestone

plan_milestone is a command for Claude Code from Helmi/claude-simone. It costs 0 tokens per session (1,477 once invoked), scanned A, original, MIT.

An interactive command for creating a project milestone, a documented delivery target made up of related work. It adds the milestone’s files and updates the project’s existing documentation and tracking structure.

In plain words
What is it for?
Use it to define and add a new milestone to a project managed with the specified .simone documentation structure. It can help scope the work, choose its place and name, create supporting documents, update the project manifest, and validate the result.
Why use it?
It prevents milestones from being created with missing metadata, unclear scope, or disconnected project records. It also includes checks to confirm that the new milestone fits the project.

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

plan_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.

Plan and Create New Milestone - Execute from Top to Bottom

Creates a new milestone with proper structure, documentation, and project integration through an interactive, adaptive process.

Create a TODO with EXACTLY these 8 items

  1. Parse arguments and analyze project context
  2. Interactive milestone scoping and definition
  3. Determine milestone structure and naming
  4. Create milestone directory and meta file
  5. Guide supporting documentation creation
  6. Update project manifest with milestone
  7. Validate milestone coherence and alignment
  8. Report milestone creation and next steps

1 · Parse arguments and analyze project context

CRITICAL: You are given additional Arguments: <$ARGUMENTS>

USE PARALLEL SUBAGENTS to do these tasks:

  • Parse arguments for suggested milestone name/focus (defaults to interactive creation)
  • Read .simone/00_PROJECT_MANIFEST.md to understand current project state
  • Scan .simone/02_REQUIREMENTS/ to identify existing milestones and numbering
  • Read .simone/01_PROJECT_DOCS/ARCHITECTURE.md to understand project scope
  • Check latest project review in .simone/10_STATE_OF_PROJECT/ for current status
  • IMPORTANT: Understand project phase and what logical next milestone should be

2 · Interactive milestone scoping and definition

Conversational milestone definition:

If arguments provided:

  • "I see you want to create a milestone for: [arguments]"
  • "Let me understand the scope better..."

If no arguments:

  • "Let's define your next milestone based on the current project state"
  • "I see you're currently on [current milestone] - what should we focus on next?"

Interactive questions (adapt based on context):

  • "What's the main goal of this milestone?"
  • "What key deliverables should be completed?"
  • "Are there any specific technical challenges or requirements?"
  • "How does this milestone advance the project toward its long-term vision?"
  • "What would 'done' look like for this milestone?"

Keep conversational and adaptive - don't interrogate, just gather what's needed

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.
