Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00155 | $0.01250 |
| Opus 5.5 | $0.00062 | $0.00500 |
| Sonnet 5.5 | $0.00031 | $0.00250 |
| Haiku 4.5 | $0.00015 | $0.00125 |
Grade A, and why
kb 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.
Route the request
Route the request before discovering, installing, or running the CLI. A setup, evolution, or custom-ritual request begins with read-only inspection and an approved proposal; it does not require a runtime merely because this skill was selected.
| User intent | Read |
|---|---|
| Design, set up, or evolve a KB; choose its boundaries and conventions; or define a recurring KB ritual | Customize a KB setup; add Companion skill contracts only when the proposal includes a new or revised skill |
| Recover work from an earlier session, 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 |
| 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; add browser authentication for signed-in sources and platform routing when route choice or completeness matters |
| Import, extract, archive, OCR, or convert a local or public PDF into Markdown | Save a PDF; add PDF image review 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 and use its structure |
| Review recurring ideas, promote concepts, or add and verify typed relationships | Percolate concepts and relationships |
| Refresh or validate the catalog, graph, attachments, repository scopes, context mappings, or overall vault health | Refresh and check the knowledge base |

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.

kb is a skill published in the GitHub repository hraness/kb (13 stars, last pushed 1mo ago), licensed MIT. It adds 155 tokens to every session and 1,250 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

Use Exomem's Epistemic Inbox and audit queues to surface stale conclusions, contradictions, relation debt, and unprocessed sources safely.
exomem
Use Exomem for governed knowledge-base recall, capture, compilation, connections, review, and preservation. Engage for Exomem, KB, vault, Obsidian or notes, including save, log, compile, "interesting, save it", and "what did I conclude"; consult prior project/domain knowledge and capture durable outcomes according to…
