What it does

Spec Governance is an agent skill from Arch1eSUN/Arcgentic. Use when a round uses proposal/design/tasks/spec/archive artifacts or needs OpenSpec-style artifact validation without depending on the OpenSpec CLI.

Its SKILL.md is about 240 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows. The repository describes itself as: Mechanical plan/dev/self-audit/external-audit gates for AI coding agents, with a configurable role-routing topology engine, an MCP-UI live status panel, and native-tooling Claude… The licence is MIT.

When your agent uses it

  • A round uses proposal/design/tasks/spec/archive artifacts
  • Needs OpenSpec-style artifact validation without depending on the OpenSpec CLI

Example prompts

  • “/spec-governance”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Check that the change directory has proposal.md, design.md, tasks.md, and
  2. Count complete and incomplete tasks.
  3. Validate archive readiness without moving files
  4. Map proposal/design/tasks/spec facts into handoff and audit facts.

What it can do on your machine

Read from SKILL.md and the folder at commit 8539955. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Spec Governance loads about 239 tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 69 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~239

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

spec-governance

Validates OpenSpec-style change artifacts as inputs to arcgentic planning, development, and audit.

Workflow

  1. Check that the change directory has proposal.md, design.md, tasks.md, and specs/**/*.md.

  2. Count complete and incomplete tasks.

  3. Validate archive readiness without moving files:

    bash
    arcgentic spec-governance status openspec/changes/<change>
arcgentic spec-governance validate openspec/changes/<change>
arcgentic spec-governance archive openspec/changes/<change>

  4. Map proposal/design/tasks/spec facts into handoff and audit facts.

Boundaries

  • V1 archive is validate-only.
  • Do not add an OpenSpec npm dependency.
  • Do not replace arcgentic's state machine with OpenSpec states.
