mine-plan-create

mine-plan-create is a skill for Claude Code, Codex from 6ixGODD/mine. It costs 119 tokens per session (5,939 once invoked), scanned A, original, MIT.

A planning workflow that turns software requirements and repository research into a detailed implementation plan. It uses the repository's architecture decisions and verified outside documentation as evidence.

In plain words
What is it for?
Use it to create or update an executable plan for a software change, including its scope, technical approach, ownership, and verification steps.
Why use it?
It gives coding agents the design choices, files, interfaces, tests, and checks they need, so they do not have to rediscover important decisions while implementing the work.

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

mine-plan-create 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 3d 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 — 482 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MINE Plan Create

Create an implementation-ready plan from requirements, current repository evidence, the architecture source of truth, and freshly verified external documentation.

A completed plan is an executable engineering contract, not a brainstorm, backlog, generic checklist, or restatement of the user's request. Make it precise enough that a weak implementation agent can execute it without inventing product decisions, interfaces, algorithms, file ownership, tests, or verification commands.

Integration: MCP tools and CLI fallback

mine-plan-create registers and queries plans through two paths, in this order of preference:

  1. MCP tools (preferred) - when the current Agent runtime exposes the MINE MCP server (mine mcp serve), call the typed MCP tools. They return the same DTOs as the JSON CLI and never touch the execution-graph files.
  2. JSON CLI (deterministic fallback) - when MCP is unavailable, call mine --format json commands. Never parse human output.

Never invent an MCP tool, CLI command, flag, JSON field, or lifecycle transition that the current binary does not expose. Never edit docs/plan/execution-graph.toml or docs/plan/execution-graph.md directly.

The accepted MCP tools mine-plan-create may use:

  • mine_graph_status (no arguments) - read the current revision, branches, and plan count (carry data.revision as the expected revision on writes).
  • mine_graph_validate (no arguments) - validate the graph after registration.
  • mine_graph_ready (no arguments) - read the ready frontier.
  • mine_plan_show (id) - look up a plan node.
  • mine_design_readiness (scope?) - verify that applicable planning-blocking ADRs and the detailed Design are ready for the requested scope.
  • mine_adr_show (id) / mine_adr_list / mine_adr_validate - inspect the digest-bound ADR registry before planning.
  • mine_plan_add (id, path, title, design_references, exclusive_write_paths?, hard_predecessors?) - register a new DRAFT plan node.
  • mine_design_validate (no arguments) - confirm design references resolve.

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

mine-plan-create is a skill published in the GitHub repository 6ixGODD/mine (17 stars, last pushed 5d ago), licensed MIT. It adds 119 tokens to every session and 5,939 once invoked, about $0.0006 per session on Opus 5. 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 2026-08-30.
