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.

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 | $0.00133 | $0.01889 |
| Opus 5 | $0.00067 | $0.00945 |
| Sonnet 5 | $0.00027 | $0.00378 |
| Haiku 4.5 | $0.00013 | $0.00189 |
Grade A, and why
knowledge-base 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 2d 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 — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Knowledge Base pack — how to work here
This project uses the source-grounded knowledge-base layout. The whole point is a closed evidence loop: nothing canonical exists without a traceable chain back to a preserved source. This skill holds the workflow so the templates and log.md can stay clean — when you create a doc from a template you get structure, and the how lives here.
This skill is pack guidance. The platform
/open-knowledgeskill (read/write/preview/linking/grounding rules) still governs every markdown operation — this layers the KB workflow on top.
Link at creation
The user watches your build live — the editor follows the file you're writing, and the knowledge graph assembles on screen as pages get linked. No view management on your part; just author well: every page carries its links from the moment it's written (at minimum the hub/index page and its most related siblings — an unlinked page is invisible in the graph), and related pages share a cluster: frontmatter value (e.g. cluster: architecture) so the graph's cluster coloring makes the map read at a glance.
The three layers
external-sources/ raw sources, saved verbatim (produced by `ingest`)
↓ cite
research/ provisional analysis (produced by `research`)
↓ promote
articles/ canonical, decided knowledge (produced by `consolidate`)
The loop is ingest → research → consolidate, mapped to Karpathy's three-layer knowledge-base pattern. Every downstream claim traces upstream to a preserved source. Cite local paths in external-sources/, never bare web URLs — the KB must survive link rot.
Karpathy's insight: "The tedious part of maintaining a knowledge base is not the reading or the thinking — it's the bookkeeping." Humans abandon wikis because maintenance costs exceed perceived value. These procedures exist so an agent can do the bookkeeping (fetching, summarizing, cross-linking, superseding) without fatigue. Skipping the cross-linking, supersedes chains, or raw-source preservation is what turns a useful wiki back into an abandoned one.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

knowledge-base is a skill published in the GitHub repository inkeep/open-knowledge-skills (6 stars, last pushed 4d ago), licensed MIT. It adds 133 tokens to every session and 1,889 once invoked, about $0.0007 per session on Opus 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 2026-08-31.
