mission-driver

mission-driver is a skill for OpenCode from entropy-cloud/attractor-guided-engineering-template. It costs 199 tokens per session (5,347 once invoked), scanned A, original, MIT.

A development workflow that turns a project goal into a roadmap and repeatedly checks, reviews, plans, executes, drafts, and audits the work. It can be used with projects written in Node, Python, Java, Go, or other languages.

In plain words
What is it for?
Creating development roadmaps, configuring missions, running planned implementation work, checking results, and auditing whether a project goal is complete.
Why use it?
It organizes longer development tasks into a repeatable loop and uses each project's own tests and instructions to guide progress.

Skill for OpenCode

Written for OpenCode: installed under .opencode/. Also seen: mentions subagents; mentions AGENTS.md; mentions OpenCode.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./tools/mission-driver.sh draft "<goal description>" \.

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

mission-driver 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 1mo 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.

mission-driver — Roadmap creation and mission execution

This skill operates the tools/mission-driver/ engine shipped with this repo. It is stack-agnostic: it works for Node, Python, Java, Go, or any project whose verification commands can be expressed as shell strings. Project-specific values (test command, module layout, commit format) are read from missions/base.json, docs/context/project-context.md, and AGENTS.md rather than hardcoded here.

Companion docs (read on demand, not all at once):

  • tools/mission-driver/docs/user-manual.zh.md / user-manual.en.md — full training handbook
  • tools/mission-driver/README.md — command cheat-sheet
  • tools/mission-driver/EXECUTION-PRINCIPLE.md — internal execution deep dive
  • tools/mission-driver/TROUBLESHOOTING.md — diagnostics when stuck
  • docs/plans/00-plan-authoring-and-execution-guide.md — plan format and lifecycle
  • references/mission-config-schema.md — full mission.json schema (companion to this file)
  • references/roadmap-template.md — roadmap structure with annotated example

Mental model

A mission = a fixed config (missions/<name>.json) for one development goal. The engine reads it and enters a loop:

CHECK (health: tests/build pass)
  → REVIEW_PLANS (review draft plans → promote active; empty forEach = passthrough)
  → EXEC_PLANS (one plan-execution subflow per active plan:
                   EXECUTE → CLOSURE_SCRIPT_CHECK → CLOSURE_AUDIT → BUILD_VERIFY)
  → DRAFT_PLANS (draft 1-3 plans from roadmap → sub-agent review → promote active)
  → [loop back to REVIEW_PLANS]
  → nothing to draft → DEEP_AUDIT (multi-audit + open-audit → draft remediation plans)
                       → REVIEW_PLANS (execute audit-created plans)
  → ... until maxAuditRounds exhausted and nothing outstanding

Key facts:

  • Roadmap precedes mission. The draft command will generate both roadmap and missions/<name>.json from a single description, but only after the brief stage confirms scope is clear.
  • missions/<name>.json is pure static config — no runtime state. The engine's runtime state lives in _tmp/<runDir>/run-state.json.
  • Every AI step is a child opencode run process; logs land in _tmp/<ts>-mission-driver/.
  • Plan lifecycle: draft → (REVIEW_PLANS) → active → (EXEC_PLANS) → completed. Subflow plan-execution runs once per active plan.
  • Ctrl-C / SIGTERM is caught by main.js for graceful process-tree cleanup.
  • Plan format is a fixed contract enforced by tools/mission-driver/src/plan-check.mjs.

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.
