historic_sql_table_digest
Convert one changed historic-SQL table usage bucket into typed table usage evidence for deterministic _schema projection.

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Historic SQL Table Digest Use this skill when the WorkUnit raw file is one `tables/<schema>.<name>.json` file from the `historic-sql` adapter. ## Required Workflow 1. Read the WorkUnit notes first. 2. Call `read_raw_file` for the single `tables/<schema>.<name>.json` raw file. 3. Read `manifest.json` only if the table JSON omits the dialect or the WorkUnit notes are unclear. 4. Produce one concise usage narrative for this table from the staged table JSON. 5. Call `emit_historic_sql_evidence` exactly once with `kind: "table_usage"`. 6. Stop after the evidence tool succeeds. ## Identifier Verification Protocol Before writing a wiki page or SL source on any topic: 1. `discover_data({query: "<topic>"})` - see what wikis, SL sources, and raw tables already exist. Prefer updating existing pages over creating new ones. Before emitting any `schema.table` or `schema.table.column` into a wiki body, SL source, `tables:` frontmatter, `sl_refs`, or `emit_unmapped_fallback`: 2. `entity_details({connectionId, targets: [{display: "<identifier>"}]})` - confirm the identifier resolves; inspect native types, FK/PK, and sampleValues. 3. For literal values from the source, such as status codes or plan

What does the historic_sql_table_digest skill do?
Convert one changed historic-SQL table usage bucket into typed table usage evidence for deterministic _schema projection.
How do I install it?
Run `npx skills add Kaelio/ktx --skill historic_sql_table_digest --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From Kaelio/ktx, a repository with 1,526 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
