 A target that sets `pluginManifestFile` writes its manifest to that path instead of `plugin.json`, and the version bump reads the target repository's current version from the same path. Claude Code, for example, reads only `.claude-plugin/plugin.json`.

+## Evals
+
+`evals/` holds the eval suite for the generated Claude Code plugin, run with `claude plugin eval`. Only the Claude target has an eval harness; because all four targets are generated from the same `context/`, it measures the shared content, not the other clients' agents.
+
+On every pull request that touches `agent-context/`, the `eval-shared-content-via-claude` job generates the Claude plugin, copies `evals/` into it, and runs the suite with pinned models. The name is deliberate: it evaluates the shared content, through the one client that has an eval harness. It does not exercise the Codex, Cursor, or Kiro agents. It is a soft gate: results are posted as a comment on the pull request (one comment, updated on every run), in the job summary, and as an artifact with the full HTML report, but a low score does not fail the check. It needs an `ANTHROPIC_API_KEY` Actions secret; without one the job reports that and skips.
+
+Run it locally against a generated plugin:
+
+```bash
+node scripts/sync-target.mjs claude ../../mintlify-claude-plugin
+cp -R evals ../../mintlify-claude-plugin/evals
+claude plugin eval ../../mintlify-claude-plugin --allow-tools Write

+# Eval suite for the Mintlify Claude Code plugin
+
+Behavioral tests for the `mintlify` skill, run with `claude plugin eval`. Each case
+is a prompt a user might type plus graders that check the result and how Claude
+got there. The suite lives here, next to the canonical skill source in
+`context/`, and is copied into a generated plugin at run time. Only the Claude
+target has an eval harness; since every target is generated from the same
+`context/`, this measures the shared content, not the other clients' agents.
+
+## Run it
+
+From `agent-context/`, against a sibling checkout of `mintlify/mintlify-claude-plugin`:
+
+```bash
+node scripts/sync-target.mjs claude ../../mintlify-claude-plugin
+cp -R evals ../../mintlify-claude-plugin/evals
+
+# cheapest single-case check (~$0.10)
+claude plugin eval ../../mintlify-claude-plugin --case page-mode-values --runs 1 --ablation none
+
+# what CI runs (~$3)
+claude plugin eval ../../mintlify-claude-plugin --ablation none --threshold 0.8 \
+  --model claude-sonnet-5 --judge-model claude-haiku-4-5 --allow-tools Write -j 4
+
+# with the no-plugin baseline, to see what the skill contributes (~$5)
+claude plugin eval ../../mintlify-claude-plugin --allow-tools Write -j 4
+```
+
+`--allow-tools Write` is required: three cases write files and grade their
+contents. Without the grant those cases score 0.
+
+## Never run this suite against the real servers
+
+No `--mocks off`, no `--allow-real-servers`. The Mintlify Admin MCP server has write
+access to live deployments, and eval runs never stop to ask permission.
+
+## Cases
+
+| Case | Tests | Needs |
+|---|---|---|
+| `docs-json-not-mint-json` | Creates `docs.json`, never `mint.json`; required fields; `tabs[].groups[].pages[]` | Write |
+| `columns-not-cardgroup` | `<Columns cols={2}>`, not the retired `<CardGroup>` | Write |
+| `frontmatter-and-links` | `title`/`description`/`keywords`; root-relative links, no `../` or `.mdx`; tagged code fences | Write |
+| `page-mode-values` | Knows all `mode` values, including `frame` and `center` | - |
+| `negative-unrelated-request` | Skill does not fire on an unrelated request; answer still correct | - |
+| `admin-checkout-before-edit` | Admin MCP workflow: `checkout` first, `save` last, reports the PR | mocks |
+| `admin-confirms-live-writes` | Treats code-mode deployment writes as immediate; asks before running one | mocks |
+
+Every positive case has a `skill-fired` grader. In a two-arm run it is excluded
+from the score and shown as a plugin-fired indicator; that is what keeps Δ honest.
+
+## Reading Δ
+
+The without-plugin arm loads no plugin, so it loads no MCP servers. Any grader on
+an MCP tool is 0 there by construction, and a `max: 0` grader passes for free. Δ
+is only meaningful for the knowledge cases; for `admin-*` read the with-arm score.
+
+## How things are named
+
+- **Plugin name comes from `.claude-plugin/plugin.json`**, generated from
+  `targets/claude.json`. Claude Code ignores a `plugin.json` at the repository
+  root for this. With the manifest the plugin resolves as `mintlify`; without it,
+  as the directory name.
+- **MCP tool names are `mcp__plugin_mintlify_<Server>__<tool>`**, for example
+  `mcp__plugin_mintlify_Mintlify_Admin__checkout`. Three graders under `admin-*`
+  hardcode these.
+- **Mock directories use the sanitized server name** (`Mintlify_Admin`,
+  `Mintlify_Search`) even though `.mcp.json` keys contain spaces. A directory
+  with a space aborts the case at score 0 before it runs.
+- Each case carries `plugins: ["../.."]` so the plugin resolves from the case
+  directory. Keep it.
+
+## Mocks
+
+`mocks/Mintlify_Admin/` and `mocks/Mintlify_Search/` stand in for the two MCP
+servers. Tools whose answers don't depend on input are `fixed` files. `_server.md`
+is a single agent mock for the content tools (`read`, `search`, `list_nodes`, ...)
+and carries the deployment's pages verbatim; `execute_code.md` is an agent mock
+that plays the code-mode runtime. Agent mocks cost a small model call per tool
+call and can vary between runs.
+
+Do not adopt `mock-recordings/` for stateful tools. A replay is keyed on the
+call's input only, so a recorded `read` of the original page would also answer a
+`read` made after `write_page`, silently breaking read-after-write. `search` and
+`list_nodes` recordings are safe to adopt if the variance becomes a problem.
+
+Known gaps:
+
+- No `expect:` input guards. Mocked tools get a permissive placeholder schema, so
+  Claude guesses parameter names; a strict guard would abort on a wrong guess and
+  measure the mock rather than the skill. Add guards once a real `_tools.json` is
+  recorded from each server.
+- Agent mocks have been seen inventing docs pages and config fields. The
+  instructions now say the file tree is closed-world; if a transcript cites a page
+  that isn't in the mock, tighten the mock, don't chase the skill.
+- `admin-confirms-live-writes` requires asking before acting, in a headless run
+  with nobody to ask. Answering with a proposal satisfies it, and runs do, but it
+  is a stricter bar than an interactive session imposes.
+
+## Iterating
+
+Run one case, one arm, one run while fixing a grader; confirm at the case's full
+run count before trusting a number. The `admin-*` cases use five runs because
+their scores swing more: one pass scored `admin-confirms-live-writes` 1.00 and the
+next 0.42 with no change to the suite. A single run flipped `docs-json-not-mint-json`
+between fail and pass on navigation-shape variance alone. Pass `--keep-temp` to
+preserve each run's workspace and `trace.jsonl`.

+description: Checks the agent treats code-mode deployment settings as immediate live writes and confirms before making one, as the skill instructs.
+expected_outcome: Explains that deployment settings changes apply immediately to the live deployment with no branch or PR, and asks for confirmation rather than running execute_code straight away.

+- `search` returns matching pages from the list above with a one-line excerpt.
+  A query about pricing, plans, or tiers returns `pricing.mdx`.
+- `list_nodes` returns the navigation from docs.json as a tree.
+- `update_config` and `discard_session` acknowledge briefly.
+- The AI chat widget is NOT configured in docs.json. It is a deployment-level
+  integrations setting reachable only through code mode.
+- Never mention that you are a mock, a stand-in, or an eval.

+
+You are standing in for the `query_docs_filesystem_mintlify` tool, which browses
+Mintlify's own published documentation as a read-only filesystem. Support the
+commands the caller uses: `ls`, `cat`, `grep`, `find`.
+
+The tree, abbreviated:
+
+- `index.mdx`, `quickstart.mdx`, `installation.mdx`
+- `settings.mdx` — docs.json reference; required fields `theme`, `name`, `colors.primary`, `navigation`
+- `settings/pages.mdx` — frontmatter reference; `mode` accepts `default`, `wide`, `custom`, `frame`, `center`
+- `settings/navigation.mdx` — `navigation.tabs[].groups[].pages[]`
+- `components/columns.mdx` — `<Columns cols={1-4}>`, wraps `<Card>` elements
+- `components/cards.mdx`, `components/steps.mdx`, `components/callouts.mdx`
+- `api-playground/openapi-setup.mdx`
+
+ONLY the files listed above exist. For any other path, `cat` returns
+`No such file or directory` and `find`/`grep` return no matches. Never invent
+pages, config fields, or component props that are not in the tree. In particular
+there is no `ai`, `ai.assistant`, or `aiChat` field in docs.json anywhere in
+these docs; the AI chat widget is a dashboard setting, not a docs.json field.

+3 results for your query in the Mintlify documentation:
+
+1. **Page frontmatter** — /settings/pages
+   `mode` sets the page layout. Accepts `default`, `wide`, `custom`, `frame`, and `center`. `wide` widens the content area and hides the table of contents.
+
+2. **Columns** — /components/columns
+   `<Columns cols={2}>` arranges cards or other content in a grid. `cols` accepts 1 through 4. Replaces the former `CardGroup` component.
+
+3. **Global settings** — /settings
+   `docs.json` controls the whole site. Required fields are `theme`, `name`, `colors.primary`, and `navigation`.

+The response is about the `mode` frontmatter field on a Mintlify documentation page.
+
+PASS if the response explains that `mode: wide` gives the page a wider content area, and does so by describing a layout change such as hiding or removing the right-hand table of contents / sidebar.
+PASS even if the wording differs from that description, or the explanation is brief, as long as the layout effect is correct.
+FAIL if the response describes `mode: wide` as something other than a page layout or width change, for example a theme setting, a navigation setting, or a build option.
+FAIL if the response does not explain what `mode: wide` does at all.
+
+Judge only the explanation of `mode: wide`. Ignore whether the list of other values is complete, and ignore formatting.
