Kb

Work with KB

Use hraness/kb to preserve and retrieve inspectable agent memory in Markdown and Git. Select the smallest workflow that matches the request, then load only its references.

Prepare the runtime

Use an existing kb command when one is available. Do not reinstall or upgrade it merely because this skill loaded.

If kb is missing, check for Bun. Bun is the required runtime. When Bun is also missing, install it with the official instructions at under the environment's normal approval rules, then repeat command discovery. Install KB only while kb remains missing:

command -v kb >/dev/null 2>&1 || {
  command -v bun >/dev/null 2>&1 || exit 1
  bun add --global @hraness/kb@0.17.2
}
kb --help

The exact npm version is the immutable release owned by this skill. Do not replace it with latest, a branch, or an unpinned package source. Both installed commands require Bun 1.3.14 or newer in PATH. Run kb doctor when the chosen workflow may need browser capture, media tools, PDF extraction, OCR, or local semantic search.

Installation ends after command verification. Never run kb init, create a vault, refresh a catalog, or edit Markdown as an installation side effect. Initialize or mutate a vault only when the user's request requires that change.

Route the request

| User intent | Read | | --- | --- | | Find notes, search one vault or an authorized portfolio, load repository-path context, inspect plans or decisions, follow backlinks or relationships, audit vault organization, or retrieve Git provenance | [Query the knowledge base](references/query.md) | | Save, clip, scrape, or archive a URL, article, social post or thread, GitHub or Discourse discussion, signed-in page, feed, inbox, private document, WhatsApp conversation, or YouTube page | [Capture web content](references/save-url.md); add [browser authentication](references/url-authentication.md) for signed-in sources and [platform routing](references/url-platforms.md) when route choice or completeness matters | | Import, extract, archive, OCR, or convert a local or public PDF into Markdown | [Save a PDF](references/save-pdf.md); add [PDF image review](references/pdf-review.md) for scans, screenshots, conversations, charts, or mixed media | | Create or update an implementation plan, proposal, RFC, migration plan, execution audit, or phased checklist in the vault | [Write a durable plan](references/plan.md) and [use its structure](references/plan-structure.md) | | Review recurring ideas, promote concepts, or add and verify typed relationships | [Percolate concepts and relationships](references/percolate.md) | | Refresh or validate the catalog, graph, attachments, repository scopes, context mappings, or overall vault health | [Refresh and check the knowledge base](references/refresh.md) |

Read more than one primary reference only when the request spans those workflows. For example, saving a source and linking it from a maintained note uses the capture workflow followed by the relevant percolation and refresh steps.

Preserve the KB contract

• Resolve KB_ROOT to the existing vault directory that contains its managed

or authored index.md. Read the applicable repository and vault AGENTS.md files before writing. Do not assume the session started in the vault.

• Treat authored Markdown and Git as the record. Catalogs, backlinks, graph

reports, search indexes, embeddings, and percolation candidates are derived views.

• Open cited notes and source records before turning search results, tags,

mentions, or similarity into a conclusion. Author only relationships that the source note's prose and evidence support.

• Keep source capture separate from synthesis. Preserve access, pagination,

extraction, OCR, and configured-limit failures instead of upgrading partial evidence to complete.

• Follow the selected reference's final checks. In a managed-catalog vault,

parallel edit lanes use kb check --root "$KB_ROOT" --no-catalog; the integrating agent performs one refresh and normal check.
