At a glance

Explain GRACE 4 methodology, .grace artifacts, semantic anchors, change lifecycle, verification, and migration boundaries.

  • Works in 6 steps: grace-init creates the .grace skeleton. → grace-spec creates an active change spec… → grace-plan creates assertions, scopes,… → …
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Grace Explainer is an agent skill from osovv/grace-marketplace. Explain GRACE 4 methodology, .grace artifacts, semantic anchors, change lifecycle, verification, and migration boundaries.

Its SKILL.md is about 300 tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including reference files (for example `agents/openai.yaml`, `references/contract-driven-dev.md` and `references/knowledge-graph.md`).

The repository describes itself as: GRACE (Graph-RAG Anchored Code Engineering): open Agent Skills for contract-driven AI code generation with semantic markup, knowledge graphs, and support for Claude Code, Codex… The licence is MIT.

Workflow steps

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

  1. grace-init creates the .grace skeleton.
  2. grace-spec creates an active change spec and waits for approval.
  3. grace-plan creates assertions, scopes, and T-* implementation tasks.
  4. grace-execute runs sequential or parallel-safe mode from the approved plan.
  5. grace lint and grace status provide validation and health evidence.
  6. Existing GRACE 3 projects use grace-migrate; the CLI validates the result but does not convert legacy docs directly.

What it can do on your machine

Read from SKILL.md and the folder at commit 70f5ec4. 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.

    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

Grace Explainer loads about 298 tokens when it runs, and up to ~5.9k if it reads all its reference files. Until then it costs about 35 tokens; SKILL.md has 129 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~35
When it runs · the whole SKILL.md, loaded when a task matches
~298
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5.9k

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.

<skill>
<core_model>
GRACE 4 uses `.grace` as the durable project model:
  • .grace/context stores requirements, technology, principles, deployment, and UX constraints.
  • .grace/graph stores graph indexes and routed graph documents with GD-*, M-*, and DF-* tags.
  • .grace/verification stores verification indexes and routed V-M-* entries.
  • .grace/changes stores active and archived C-* change bundles with GraceChangeSpec, optional non-normative design context, and GraceChangePlan. </core_model>
<workflow>
1. `grace-init` creates the `.grace` skeleton.
2. `grace-spec` creates an active change spec and waits for approval.
3. `grace-plan` creates assertions, scopes, and `T-*` implementation tasks.
4. `grace-execute` runs sequential or parallel-safe mode from the approved plan.
5. `grace lint` and `grace status` provide validation and health evidence.
6. Existing GRACE 3 projects use `grace-migrate`; the CLI validates the result but does not convert legacy docs directly.
