okf-mcp: Skill for Codex

.agents/skills/okf-v02-migration/SKILL.md

okf-v02-migration is a skill for Codex from mfdaves/okf-mcp. It costs 49 tokens per session (687 once invoked), scanned A, original, MIT.

A checker and proposal tool for moving an Open Knowledge Format catalogue from version 0.1 to version 0.2. Open Knowledge Format is a structured way to describe catalogue data and its sources.

In plain words
What is it for?
Use it to check a catalogue migration, find identity or alias collisions, report malformed citations and paths, and prepare proposals that require confirmed mappings.
Why use it?
It identifies migration blockers and unsafe or uncertain changes before files are modified, so you do not accidentally lose provenance or overwrite generated files.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is mfdaves/okf-mcp's own configuration. It tells Codex how to work on okf-mcp 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 okf-mcp 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

okf-v02-migration 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 9d 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.

OKF v0.2 Migration

Use the package's deterministic migration checker and proposal tools. Never rewrite catalog files directly, invent provenance or verification claims, accept proposals automatically, or mutate a remote bundle.

Workflow

  1. Confirm the repository worktree state before creating proposals. Preserve unrelated changes and stop if migration targets overlap unreviewed edits.
  2. Run okf --root <catalog> migrate check. In an optional multi-root project, run okf --project <config> migrate check <bundle>. Record the classification, blockers, identity collisions, generated-file skips, referenced assets, and migration readiness.
  3. Resolve blockers before proposing anything:
    • Ask the catalog owner for a truthful generated.by actor for every legacy timestamp; require an explicit confirmed mapping.
    • Route generated files back to their generator instead of proposing direct edits.
    • Resolve malformed citations, conformance errors, unsafe paths, and ID or alias collisions without guessing.
    • Supply mappings as {"<concept-uri-or-path>":{"by":"<actor>","confirmed":true}}; $default may be used only after the owner confirms that one actor truthfully applies to every reported timestamp.
    • Use human:<id>, process:<id>, or <provider>/<model> actor syntax. The checker rejects an omitted or non-boolean confirmation.
  4. Run okf --root <catalog> migrate preview '<actor-mappings-json>', or supply the bundle id in multi-root project mode. Review every per-file change against field-mapping.md.
  5. Present the preview and wait for explicit approval before calling okf_propose_v02_migration. That MCP tool requires a writable local root and --authoring; there is intentionally no CLI command that creates proposals.
  6. The proposal tool may create a migration manifest and individual child proposals only. Do not accept any child unless the user explicitly approves that proposal.
  7. Accept the reserved index.md version proposal only after every Stage-A concept proposal is accepted and the whole bundle validates.
  8. Run project validation again and report local evidence, retained legacy fields, remaining generator work, and any external or remote state not verified.

What ships with it

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.
