aws-samples/sample-okf-llm-wiki is a sample system that turns AWS data sources into portable knowledge bundles: organized Markdown documents explaining datasets, tables, relationships, metrics, and known issues. It serves those bundles to AI agents through the Model Context Protocol, using sources such as AWS Glue Data Catalog and Amazon Redshift. The catalogue entries support the system's setup and workflow.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00102 | $0.08994 |
| Opus 5 | $0.00051 | $0.04497 |
| Sonnet 5 | $0.00020 | $0.01799 |
| Haiku 4.5 | $0.00010 | $0.00899 |
Grade A, and why
okf-authoring 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 8d 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.

Licensed MIT-0
The repository is licensed MIT-0, which this catalogue does not treat as permission to reproduce the file. Read it at the source.
What ships with it
7 files 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.

okf-authoring is a skill published in the GitHub repository aws-samples/sample-okf-llm-wiki (26 stars, last pushed yesterday), licensed MIT-0. It adds 102 tokens to every session and 8,994 once invoked, about $0.0005 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 2026-08-30.

okf-viz
Visualizer that renders an Open Knowledge Format (OKF) bundle into a single self-contained interactive index.html — a three-pane explorer (tree/filters, a Cytoscape graph with switchable layouts, and a rendered reader) written next to index.md. Use when you want a human-browsable, graph view of an OKF bundle, or to…
okf-csv
CSV connector that produces and ingests Open Knowledge Format (OKF) bundles from a directory of CSV files. Infers each file's column schema (integer/number/boolean/date/string) by sampling rows, optionally embeds a per-column data profile and sample rows, and syncs descriptions back to a .okf-metadata.yaml sidecar.…
okf-git
Git repository connector that produces and ingests Open Knowledge Format (OKF) bundles documenting repository file trees plus commit-history metadata (times, authors, messages), honoring .gitignore and .okfignore. Use when documenting or cataloging a Git repository as an OKF bundle.
okf-lint
Deterministic validator for Open Knowledge Format (OKF) bundles. Checks spec conformance (root index.md carries only okfversion, subdirectory index.md files carry no frontmatter, every concept has a non-empty type) plus enrichment coverage (placeholder descriptions, broken cross-links, orphans), and gates CI via its…
okf-openapi
OpenAPI/Swagger connector that produces and ingests Open Knowledge Format (OKF) bundles from an API contract. Parses an OpenAPI 3.x or Swagger 2.0 spec (JSON or YAML) into one concept per operation (API Endpoint) and per component schema (Schema), links endpoints to the schemas they reference as typed cross-links, and…
okf-sqlite
SQLite connector that produces and ingests Open Knowledge Format (OKF) bundles from database schemas and comments, CGO-free via modernc.org/sqlite. Use when documenting or cataloging a SQLite database, extracting its schema into OKF, or comparing/validating a database against an OKF bundle.
