# kb-query

A skill that answers questions from an existing knowledge/ bundle instead of rediscovering everything. Useful when the repo already holds synthesized concepts.

## What it does

The skill runs in two modes. Explicit: you ask what the project knows about something, or ask it to compare two things. Ambient: you are busy with another task, the repo holds relevant context, and the agent consults the bundle before answering from scratch, then returns to the task.

Navigation is progressive. The root `index.md` comes first, then the section index, then only the concepts that bear on the question, reached through cross-links. The whole bundle never gets read end to end, so on a large collection the skill leans on a search tool when one exists.

Currency and conflict handling is a step of its own. A concept marked `status: deprecated` (or `status: superseded` in older bundles) sends the skill to whatever `superseded_by` points at. When `conflicts_with` links concepts, the answer separates what authoritative sources confirm from softer signals, with dates. A concept past its `stale_after` date gets labelled stale and corroborated before anything rests on it. A good answer — a comparison, a synthesis across sources, a connection you did not know about — the skill offers to file as a new concept, with the section index and a log entry updated. A plain factual lookup stays in chat.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add stjbrown/agent-knowledge --skill kb-query -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/kb-query/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/kb-query/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add stjbrown/agent-knowledge --skill kb-query -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/kb-query/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add stjbrown/agent-knowledge --skill kb-query -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/kb-query/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install stjbrown/agent-knowledge kb-query
```

2. **Manually: put the files in place**
- File: `.github/skills/kb-query/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add stjbrown/agent-knowledge --skill kb-query -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/stjbrown/agent-knowledge --path skills/kb-query
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/kb-query/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add stjbrown/agent-knowledge --skill kb-query -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/stjbrown/agent-knowledge/tree/HEAD/skills/kb-query/SKILL.md

## When to use it
- answer a question from an existing bundle without rereading it
- compare two concepts and surface where they disagree
- trace connections between sections through cross-links
- pull bundle context into a task already in progress
- file a useful synthesis as a new concept with a log entry

## Example prompts
- What do we know about the task queue in this project?
- Compare the caching approaches in the knowledge bundle
- Check `knowledge/` for anything on auth and factor it into this task

  Answer from the knowledge bundle. Use when the user asks what they/the project know about

# kb-query — answer from the bundle

Answer a question from a [knowledge bundle](../kb/SKILL.md), or surface relevant bundle context for
another task. Because synthesis was front-loaded during [ingest](../kb-ingest/SKILL.md) or
[repository documentation](../kb-document/SKILL.md), this is mostly **navigation and assembly**,
not rediscovery. Read
[../kb/references/glossary.md](../kb/references/glossary.md) for terms.

Two modes, same procedure:

- **Explicit** — the user asks a knowledge question ("what do we know about X?", "compare A and B").
- **Ambient** — you're doing another task and a bundle in the repo has relevant context; consult it
  before answering from scratch, then return to the task.

## 1. Locate the bundle(s)

Find the bundle root (a `knowledge/` dir, or an `index.md` with `okf_version`). If `knowledge/` holds
several bundles, read `knowledge/index.md` and pick the relevant one(s); a query may span more than
one. If no bundle exists, say so and stop (offer [kb-init](../kb-init/SKILL.md)).

**Completion criterion:** the relevant bundle root(s) are identified.

## 2. Navigate by progressive disclosure

Do **not** read the whole bundle. Read the root `index.md` first, then the relevant section
`index.md`, to find candidate concepts; follow **cross-links** from there. Read only concepts
relevant to the question. (At large scale a search tool may exist — use it to find candidates, but
the retrieved unit is still a synthesized concept, not a raw chunk.)

**Completion criterion:** you have the specific concepts that bear on the question, reached by
following the index and links rather than scanning.

## 3. Read with currency and conflict awareness

Apply the reading side of the [trust model](../kb/references/trust-model.md) and the
[version profile](../kb/references/version-profile.md):

- If a concept is retired (`status: deprecated` in OKF v0.2 or legacy `status: superseded`), follow
  `superseded_by` to the current version and answer from **that** (use the old one only if the user
  asks how something evolved).
```
