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 | $0.00061 | $0.00827 |
| Opus 5 | $0.00030 | $0.00413 |
| Sonnet 5 | $0.00012 | $0.00165 |
| Haiku 4.5 | $0.00006 | $0.00083 |
Grade A, and why
okf-mysql 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 11d 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 — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MySQL OKF Connector
This skill provides a Go-based CLI tool to convert MySQL database schemas and comments (table and column comments) into Open Knowledge Format (OKF) bundles, and synchronize comments back to a MySQL database from an OKF bundle.
When to Use
Use this skill when you need to:
- Extract table structures, column definitions, keys, and native MySQL comments from a schema into a portable OKF bundle.
- Synchronize business descriptions or documentation changes written in an OKF bundle back into native MySQL table and column comments.
Setup
The connector requires Go 1.24+:
# Install the published binary (Go 1.24+) — no clone needed:
go install github.com/xSAVIKx/okf-skills/skills/[email protected]
# …or build from a clone of the repository:
cd skills/okf-mysql
go build -o okf-mysql .
How to Use
1. Produce an OKF Bundle
Extract database schema metadata and comments:
./okf-mysql produce --host <host> --port <port> --user <user> --password <password> --db <database-name> --out <output-bundle-dir> [--tables <comma-separated-table-names>] [--sample <N>] [--profile]
2. Ingest / Synchronize an OKF Bundle
Synchronize table/column descriptions from the OKF bundle back into database comments:
./okf-mysql ingest --host <host> --port <port> --user <user> --password <password> --db <database-name> --bundle <path-to-okf-bundle> [--sync]
Parameters:
--host(defaultlocalhost): MySQL host.--port(default3306): MySQL port.--user(required): MySQL user.--password(required): MySQL password. May also be supplied via theMYSQL_PASSWORDenvironment variable to keep secrets out of the command line.--db(required): Target database schema.--bundle(required for ingest): Path to the OKF bundle.--out(required for produce): Path to output OKF bundle.--tables(optional): Filter to extract only specific tables.--sample <N>(optional): Embed up to N sample rows per table as a## Samplesection in each table doc (default 0 = none).--profile(optional): Compute per-column statistics (non-null, null, distinct, min, max) and embed a## Data Profilesection.--sync(optional for ingest): If provided, runsALTER TABLE ... COMMENT = ...andMODIFY COLUMN ... COMMENT ...statements to synchronize descriptions.
What ships with it
12 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-mysql is a skill published in the GitHub repository xSAVIKx/okf-skills (33 stars, last pushed 11d ago), licensed Apache-2.0. It adds 61 tokens to every session and 827 once invoked, about $0.0003 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.

aql-authoring
This skill should be used when the user asks to "write an AQL query", "optimize an AQL query", "review AQL", or "query openEHR data" — the multi-step authoring/optimization workflow for AQL (Archetype Query Language) over openEHR clinical data. For a one-off explanation of an existing query or a single AQL…
okf-authoring
Author Open Knowledge Format (OKF) bundles — knowledge represented as a directory of markdown files with YAML frontmatter. Use when asked to create, write, generate, enrich, or validate an OKF bundle or OKF concept docs; to turn a data source (Glue database, API, database, catalog), documentation, or a research topic…
refresh-okf-mcp-token
Fetch or refresh an OAuth2 access token for the OKF Data wiki consumption MCP server. Use when the OKF MCP server returns 401/403/unauthorized/expired-token errors, when the user asks to refresh, renew, or get a new OKF MCP token, or when setting up authentication to call the okf-mcp / okfconsumption MCP runtime.
postgres
Execute queries on the Postgres database. Use this skill DIRECTLY whenever the user asks anything about database contents, counts, or data — do NOT read compose.yml or SQL migration files first.
report-authoring
The report-authoring methodology: required structure, language, evidence discipline, and figure selection. Read BEFORE your first createreport of a conversation - the tool validates shape; this is everything it cannot check.
setup
Set up the OKF MCP plugin — outputs a guide for the user to create their /.okf/credentials file with their OAuth2 client id/secret. Use when first enabling the plugin, when headersHelper fails with "Missing credentials", or when the user says "setup okf".
