PR #4099 dropped 8 auth pages from meta.json. That was a net win for
machines (Loop 5 eval: 84/100 vs 77/100, tool-routing failure mode gone)
but it made the pages unreachable by clicking. PostHog, weekday-matched
and control-adjusted, shows the affected pages down 14-64pp beyond the
site-wide baseline drift.
Restore human navigation without touching the machine-facing wins:
- authentication.mdx becomes authentication/index.mdx and the 7 sibling
auth pages move into the folder. /docs/authentication keeps its URL
(fumadocs serves index.mdx at the folder route), so Core concepts
still shows one row and the top-level sidebar row count stays 20.
- shared-connections moves into extending-sessions: it is experimental
and is a session capability, not a core auth concept.
- "Migration and security" splits into "Migration" and "Security and
data" — separator headings, not clickable rows.
- Drop AUTHENTICATION_GUIDE_URLS from app/llms.txt/route.ts. The pages
are back in the page tree, so they emit automatically under Core
concepts -> Authentication; the hardcoded list would now duplicate.
- 8 permanent redirects for the old URLs (36-42% Google entry rate on
most of them), plus existing redirect destinations repointed so none
of them chain.
- ~90 inbound links rewritten across content, api-overviews, app, lib
and agent instructions. lint:links is the gate: 0 errors.

Integration branch for the next docs release: a **sessions-first
documentation rewrite** — new and rewritten guides, example pages,
interactive components, and docs tooling — plus the supporting SDK
changes that the new docs describe.
The bulk of this PR is docs (~24k lines across ~150 commits); the SDK
changes (~5k lines) back the new guides.
## Documentation (the bulk)
- **Sessions-first restructure** — reorganized navigation and section
structure (incl. the "Sandbox (prev workbench)" section), with
v3-reorganization redirects so old URLs keep resolving.
- **Rewritten core guides** — quickstart, configuring sessions, triggers
(creating + subscribing to events), proxy-execute, toolkits
enable/disable, and common FAQ, rewritten in the house voice.
- **New example pages** — local-sandbox PR reviewer, daily standup bot,
and slack bot, with runnable build-ups.
- **New interactive components & diagrams** — triggers flow animation,
manage-connections visual, connection-refresh visual, and the
terminal-kit components.
- **Docs tooling** — a docs-graph link-graph connectivity checker,
search reprioritization (deprioritize legacy pages), and SDK-reference
regeneration.
## Supporting SDK changes
**`@composio/core` → 0.13.0 (minor)**
- `composio.sessions.create()` as the first-class sessions API
(`composio.create()` kept as an alias).
- **MCP is opt-in:** default `create()` / `use()` return native-tool
sessions (`SessionWithoutMcp`); pass `{ mcp: true }` to surface
`session.mcp`. _Migration: read `session.mcp` only after creating with
`{ mcp: true }`._
- `session.sandbox` is the canonical resolved config;
`session.workbench` kept as a deprecated alias. `sandbox` is the
preferred session-config key (`workbench` still accepted).
- `connectedAccounts.updateAcl()` graduated from experimental (alias
kept).
- `triggers.parse()` (parse + optionally verify an incoming webhook) and
`triggers.setWebhookSubscription()`.
**`@composio/experimental` → minor** — local-workbench helpers moved
onto the `@composio/experimental/workbench` subpath (out of
`@composio/core/experimental`), keeping the ~14 KB embedded Python
helper out of core. Plus the experimental Pi provider.
**`@composio/slim` → minor.**
**Python → 0.17.0** — mirrors the TS surface: `composio.sessions` mount
(`tool_router` deprecated), `triggers.parse()` /
`set_webhook_subscription()`, the `sandbox` config key, and
`connected_accounts.update_acl()`.
## Review response (#3664)
Addressed the `@composio/core` review:
- **Security:** `triggers.parse()` no longer fails open — a
present-but-empty `verifySecret` (e.g. unset `COMPOSIO_WEBHOOK_SECRET`)
now throws instead of silently skipping verification; omitting it stays
an explicit opt-out (both SDKs).
- Removed snake_case leakage from `transformWebhookSubscription` (+ the
index signature that allowed it).
- **Removed** the TS-only `connectedAccounts.link()` toolkit
auto-resolve (shipped with cancellability / orphaned-auth-config bugs
and was effectively undocumented; to be reintroduced properly later).
- Unified Python error types on `ValidationError`; added `mcp=True`
Python tests; fixed runtime-portability + error-type test assertions.
- Polished deprecation messages; fixed the backwards `/experimental`
`@deprecated` note and the `SessionWithMcp` JSDoc.
## Testing
- **TS:** `@composio/core` + `@composio/experimental` typecheck pass;
vitest green for the touched suites.
- **Python:** `test_tool_router.py` + `test_triggers.py` pass (161
tests).

fumadocs-openapi uses operationId (e.g., getToolRouterSessionBySessionId)
not slugified summaries for page URLs.

Each endpoint now shows:
- HTTP method (GET, POST, PATCH, DELETE)
- Full path with parameters
- Linked title
- Full description from OpenAPI spec
Much more useful for LLMs to understand the API.

Instead of flat files like `auth-configs.mdx`, generate as
`auth-configs/index.mdx` so they become the index page for
each API folder, avoiding duplicate sidebar entries.
