+Ship agent skills and docs inside `@tanstack/oracles`. The package now includes `skills/` with five skills: `oracles-explore` (the entry point: it probes a repository, shows what an oracle can find, and builds the first oracle with the developer), `oracles-setup`, `oracles-design`, `oracles-review`, and `oracles-evaluate-review`. It also includes `docs/`: an introduction to oracles, the oracle checklist (version 1, ORC-001 to ORC-016), a glossary, a techniques guide, model-style examples, and six instrument cards. A coding agent reads them from `node_modules`. `@tanstack/eslint-plugin-oracles` gains a README that lists its configs and rules.

+# @tanstack/eslint-plugin-oracles
+
+Lint rules for oracle files written with `@tanstack/oracles`. They report the
+shortcuts that make an oracle pass without enforcing its law, wherever a
+syntactic check can see them. They need no type information, so an agent's
+post-edit hook can run them on one file quickly.
+
+Install it at the same pkg.pr.new commit as `@tanstack/oracles`. The
+`oracles-setup` skill in that package configures it.
+
+## Configs
+
+| Config                | Files                                                                     | Rules                                                                                                       |
+| --------------------- | ------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------- |
+| `configs.recommended` | Files whose names contain `oracle` (`.ts`, `.tsx`, `.js`, `.jsx`, `.mjs`) | `no-disabled`, `no-oracle-disable`, `no-unit-test`, `oracle-property-only`, `pure-model`, `replayable-seed` |
+| `configs.production`  | `src/**` and `packages/*/src/**`                                          | `probe-form`                                                                                                |
+
+The `recommended` config also sets `linterOptions.noInlineConfig` for oracle
+files, so a directive comment cannot switch a rule off there. Fix a report;
+do not disable the rule.
+
+The `production` config covers `src/**` and `packages/*/src/**`. For source
+elsewhere, add `oracle/probe-form` with your own glob.
+
+## Rules
+
+| Rule                          | Reports                                                                                                                                                                 |
+| ----------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| `oracle/no-disabled`          | An oracle test that stops running: `.only`, a skipped body, a switch-off condition, or one run with no fixed history.                                                   |
+| `oracle/no-unit-test`         | A test in an oracle file that reaches no declared check or model: an ordinary unit test.                                                                                |
+| `oracle/no-oracle-disable`    | A directive comment that would silence an oracle rule. Oracle rules cannot be disabled inline.                                                                          |
+| `oracle/oracle-property-only` | A raw campaign (`fc.assert`, `fc.check`, or a `.prop` registration) or a legacy campaign API in an oracle file. Only `oracleProperty` declares a generated-history law. |
+| `oracle/pure-model`           | A model, check, or reach classifier that reads a clock, ambient randomness, or a timer.                                                                                 |
+| `oracle/probe-form`           | A state probe in production code that is not in the one form the production build strips.                                                                               |
+| `oracle/replayable-seed`      | A property seed that the shared replay variables cannot select.                                                                                                         |
