agents-reverse-engineer: Command for Claude Code

.claude/commands/gsd/new-milestone.md

gsd:new-milestone is a command for Claude Code from GeoloeG-IsT/agents-reverse-engineer. It costs 20 tokens per session (4,714 once invoked), scanned A, original, MIT.

A command for starting the next milestone, meaning a defined cycle of work toward a new project version, in an existing codebase.

In plain words
What is it for?
Use it to define milestone requirements, optionally research new features, create a roadmap, and prepare the project for phase planning.
Why use it?
It gathers the next goals and updates the project’s planning records instead of making you recreate the project setup.

Command for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: names the AskUserQuestion tool.

This is GeoloeG-IsT/agents-reverse-engineer's own configuration. It tells Claude Code how to work on agents-reverse-engineer itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agents-reverse-engineer configures →

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

gsd:new-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 8d 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 — 722 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This is the brownfield equivalent of new-project. The project exists, PROJECT.md has history. This command gathers "what's next", updates PROJECT.md, then continues through the full requirements → roadmap cycle.

Creates/Updates:

  • .planning/PROJECT.md — updated with new milestone goals
  • .planning/research/ — domain research (optional, focuses on NEW features)
  • .planning/REQUIREMENTS.md — scoped requirements for this milestone
  • .planning/ROADMAP.md — phase structure (continues numbering)
  • .planning/STATE.md — reset for new milestone

After this command: Run /gsd:plan-phase [N] to start execution.

<execution_context> @./.claude/get-shit-done/references/questioning.md @./.claude/get-shit-done/references/ui-brand.md @./.claude/get-shit-done/templates/project.md @./.claude/get-shit-done/templates/requirements.md </execution_context>

Load project context: @.planning/PROJECT.md @.planning/STATE.md @.planning/MILESTONES.md @.planning/config.json

Load milestone context (if exists, from /gsd:discuss-milestone): @.planning/MILESTONE-CONTEXT.md

Phase 1: Load Context

  • Read PROJECT.md (existing project, Validated requirements, decisions)
  • Read MILESTONES.md (what shipped previously)
  • Read STATE.md (pending todos, blockers)
  • Check for MILESTONE-CONTEXT.md (from /gsd:discuss-milestone)

Phase 2: Gather Milestone Goals

If MILESTONE-CONTEXT.md exists:

  • Use features and scope from discuss-milestone
  • Present summary for confirmation

If no context file:

  • Present what shipped in last milestone
  • Ask: "What do you want to build next?"
  • Use AskUserQuestion to explore features
  • Probe for priorities, constraints, scope

Phase 3: Determine Milestone Version

  • Parse last version from MILESTONES.md
  • Suggest next version (v1.0 → v1.1, or v2.0 for major)
  • Confirm with user

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.
