description: Read and query the knowledge-base vault — a personal docs-as-code knowledge database (PARA-organized). Use when the user asks what is known about a repo, policy, decision (ADR), area, or project; wants context before working in a repo; or asks to find/navigate notes by tag, type, repo, or link. Resolves the question against the Markdown notes and the generated graph index.

# Read the Knowledge Base
This vault is a personal docs-as-code knowledge database,
organized with the [PARA method](https://fortelabs.com/blog/para/).
Markdown is the source of truth; `index/graph.json` is a generated navigation
index. Use this skill to answer questions FROM the vault and to surface the
exact notes that back the answer.
Obey `AGENTS.md` (read them if not loaded this
session). This skill is read-only — do not modify notes here.
## Layout (PARA)
```
01_projects/ active efforts with a goal and an end
02_areas/ ongoing standards: policies, value-stream areas, decisions
02_areas/decisions/ global ADRs
03_resources/meta/ taxonomy + note templates
03_resources/repos/<repo>/ per-repo info.md (+ decisions/)
03_resources/repos/repo-landscape.md index of documented repos
04_archives/ inactive items
index/graph.json generated graph (nodes + edges)
README.md vault hub; AGENT_QUERY_GUIDE.md graph query reference
```
Every note carries taxonomy frontmatter: `id`, `title`, `type`
(`hub|project|guideline|policy|feature|roadmap|decision|note|meta`), `status`
(`active|draft|deprecated`), `tags`, `last_reviewed`, optional `repo`. Notes are
linked with typed markdown links — `[text](note-id){"type":"…"}` — that resolve
by `id`. Legacy `[[wiki links]]` are rejected by `make validate-graph`.
## 1. Orient
Start broad, then narrow:
- `README.md` — vault hub and entry points.
- `03_resources/repos/repo-landscape.md` — index of every documented repo, grouped.
- `02_areas/ways-of-working.md` — global engineering policy.
- `03_resources/meta/taxonomy.md` — what the frontmatter fields and PARA buckets mean.
For a repo question, read `03_resources/repos/<repo>/info.md` directly
(`ls 03_resources/repos/` to confirm the repo is documented; if absent, say so —
it is not yet in the vault).
## 2. Query the graph
`index/graph.json` is for navigation by tag / type / repo / links. Use `jq`.
Full schema and more examples are in `AGENT_QUERY_GUIDE.md`.
```bash
# all documented repos
jq -r '.nodes[].repo' index/graph.json | sort -u
# every note in one repo
jq -r '.nodes[] | select(.repo=="tenant-controller") | "\(.id)\t\(.path)"' index/graph.json
# all notes of a type (e.g. policies, decisions, projects)
jq -r '.nodes[] | select(.type=="policy") | "\(.id)\t\(.path)"' index/graph.json
# notes carrying a tag
jq -r '.nodes[] | select(.tags[]? == "kcp") | "\(.id)\t\(.path)"' index/graph.json
# most-linked (central) notes
jq -r '.nodes | sort_by(-(.inbound_count // 0))[] | "\(.inbound_count // 0)\t\(.id)"' index/graph.json | head
# outgoing links from a note, with relationship type + annotation
NOTE_ID="repo/controller-util/info"
jq -r --arg id "$NOTE_ID" '.edges[] | select(.from==$id) | "\(.type)\t\(.to)\t\(.annotation)"' index/graph.json
# incoming links to a note (who references it, and how)
jq -r --arg id "$NOTE_ID" '.edges[] | select(.to==$id) | "\(.type)\t\(.from)\t\(.annotation)"' index/graph.json
# edges of a specific relationship type (e.g. supersedes, depends-on)
jq -r '.edges[] | select(.type=="supersedes") | "\(.from) -> \(.to)"' index/graph.json
```
Full-text fallback when you do not know the tag/type/id:
```bash
grep -rIl "<term>" 01_projects 02_areas 03_resources 04_archives
```
## 3. Read the source notes
The graph gives ids and paths; the ANSWER lives in the Markdown. Open the
matched `.path` files and read them. Follow the typed markdown links
`[text](id){"type":"…"}`, resolving each to its node `path` to pull in related
policies, decisions, and repo info. Use each edge's `type` and `annotation` to
judge which links are worth following; links are the intended navigation, so
traverse them rather than guessing.
If the graph looks stale or a path is missing, you may regenerate read-only:
`python3 scripts/generate-graph.py` (does not touch Markdown). Do not commit.
## 4. Answer with citations
- Answer the question directly from what the notes say.
- Cite the backing notes by vault-relative `path` (e.g.
`03_resources/repos/gittea/info.md`) and/or `id` so the user can verify.
- Distinguish vault facts from inference. If the vault does not cover it, say so
plainly — do not invent. Note `status: draft`/`deprecated` when relevant.
- For "what links to / relates to X" questions, report the inbound/outbound
edges you found, including each edge's relationship `type` and `annotation`.
