Write a guide against the concept graph

This repo has two kinds of content that must agree:

• Concepts (plugins/runpod/skills/runpod-usage/concepts/*.yaml) hold exact facts as rules, each citing a public source. They are the source of truth for what is true.
• Guides (every SKILL.md, reference/*.md and golden path) explain, teach and demonstrate. They are the source of truth for how to do it.

A guide states facts that the concept rules support, and links to the concepts it covers. A concept is covered by at least one guide. pnpm check:guides enforces both links.

Writing or changing a guide

1. Find the concepts it touches before writing (run these in ontology/tools/):

   pnpm build:sqlite
   pnpm query tree "<concept>"      # the concept, its children and the guides that cover them
   pnpm query search "<question>"   # the rules that answer a question
   pnpm query concept "<name>"      # every rule on one concept, with evidence

2. Write from the rules. Every factual claim (a limit, a default, a state, what an action does, what exists) must match a rule. Explain it in your own words and add the how: the commands, order, pitfalls and verification.
   • If the guide needs a fact that no rule has, add the rule first with the add-concept skill, citing the spec, the public docs or a live probe. Then write the guide.
   • If a rule is wrong or out of date, fix the rule (and its evidence) in the same change.
   • Never let a guide and a rule say different things. If you find a disagreement, the public source decides which one changes.

3. Declare the links.

   Guide	Where	Example
   SKILL.md	metadata.concepts in the frontmatter	concepts: [pod, network-volume]
   Reference doc	a concepts: line in frontmatter at the top	---<br>concepts: [runpod-secret]<br>---
   Golden path	lanes, mcp, concepts, status, verified and evals in frontmatter, plus the matching > **Status:** line under the title	see plugins/runpod/skills/runpod/golden-paths/README.md

   List the concepts the guide actually explains or uses, not every word it mentions. pnpm build:bundle --suggest lists the concepts each golden path names, as candidates. A reference doc that a rule already cites as evidence is linked automatically, but list its concepts anyway when it covers more than the citing rules.

4. Point to the rules when a doc is the main explanation of a concept. End it with a short "Exact rules" section with a Markdown link to each concept file (from a reference doc the target is ../concepts/<id>.yaml).
5. Route it. A new reference doc gets a row in its skill's SKILL.md table. A new golden path gets rows in the router's table and golden-paths/README.md.

After adding or changing a concept

1. pnpm check:guides fails if the new concept has no guide. Extend an existing doc or write a new one, following the steps above.

2. Find the guides that already cover it and check they still agree with the rules:

   pnpm query tree "<concept>"                    # guides linked to it
   grep -rln "<name or alias>" ../../plugins/     # guides that mention it without a link

3. When a rule cites a skill file as evidence and you change that file, re-read the rule: grep -rn "<path>" ../../plugins/runpod/skills/runpod-usage/concepts/.

Style

Follow plugins/runpod/skills/runpod-usage/concepts/README.md → "Writing style" and the repo conventions in AGENTS.md: plain present tense, "Runpod", code identifiers in backticks, no "currently" or "not yet", and positive claims over claims that something is missing (a missing capability needs the spec or docs as evidence, and CLI absence claims are checked by hooks/check_cli_absence_claims.py).

Check

cd ontology/tools
pnpm format && pnpm validate --strict && pnpm check:guides && pnpm scan && pnpm test
cd ../.. && python3 hooks/check_links.py && python3 hooks/check_runpod_branding.py

check:guides must report no errors, and the build line "concepts with a guide" must stay at every concept.
