This PR:
- makes `session.update()` resolve to the updated server-side session
configuration instead of `void`
- exposes that configuration as `session.config` (new
`ToolRouterSessionConfig` type) on sessions from `create()`, `use()` and
attach, so the toolkit/tool allowlist is readable without dropping to
the raw client
- renames the private SDK-config member on `ToolRouterSession` to
`sdkConfig`, ending the runtime name clash that made `session.config`
look like the SDK's `ComposioConfig`
- applies the same change to the Python `ToolRouterSession` (`config`
attribute, `update()` returns it)
- adds a minor changeset for `@composio/core`
## Context
After `sessions.use(id)` there was no way to know the session's
allowlist, and `update()` threw the response away except for
`configVersion` / `preload` / `sandbox` / `warnings`. Hackathon feedback
(area 8).
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).

ExperimentalAPI was sitting inside custom_tool.py because custom tools
were the first thing the SDK exposed on the composio.experimental
namespace. Now that update_acl has moved onto the same namespace,
keeping the class in custom_tool.py reads wrong — grepping for
update_acl lands in a file named after custom tools.
Splits the class out into core/models/experimental.py. custom_tool.py
keeps the custom-tool machinery (ExperimentalToolkit, decorator
helpers, serializers); experimental.py imports what it needs from
custom_tool.py and is now the home for anything on the
composio.experimental namespace.
Pure rearrangement — no behaviour change, no public-import-path change
(composio.core.models still re-exports ExperimentalAPI). Stack-frame
depth in _get_caller_locals(depth=2) stays correct: the
decorator → user-module hop is the same regardless of which file
ExperimentalAPI.tool lives in.
Tests still pass (201/201), mypy still clean on composio/.

Aligns the Python SDK with the experimental wire shape used by Shared
Connections. The flat `account_type` / `acl_config_for_shared` kwargs on
`link()` and `authorize()` have moved under a single `experimental` dict,
and `update_acl` has moved off `composio.connected_accounts` onto the
`composio.experimental` namespace — same precedent as
`composio.experimental.tool` / `composio.experimental.Toolkit`.
The `experimental` namespace is the signal that the shape may change in
future releases. Pinning a SHARED connection in a session config and
direct execute by `connectedAccountId` are unchanged — only the
connection-create / patch / authorize surfaces are namespaced.
Also surfaces the `account_type=` filter on `composio.connected_accounts.list()`
so SHARED connections can be listed without dropping to the raw client.
The wire keeps this as a flat query param (`?account_type=`), so the
SDK keeps it flat too with the experimental signal carried in the value
enum description.
Caller migration:
# before
composio.connected_accounts.link(
user_id, auth_config_id,
account_type="SHARED",
acl_config_for_shared={"allow_all_users": True},
)
composio.connected_accounts.update_acl(
"ca_abc", allow_all_users=True,
)
session.authorize(
"github",
account_type="SHARED",
acl_config_for_shared={"allow_all_users": True},
)
# after
composio.connected_accounts.link(
user_id, auth_config_id,
experimental={
"account_type": "SHARED",
"acl_config_for_shared": {"allow_all_users": True},
},
)
composio.experimental.update_acl(
"ca_abc", allow_all_users=True,
)
session.authorize(
"github",
experimental={
"account_type": "SHARED",
"acl_config_for_shared": {"allow_all_users": True},
},
)
# new — list SHARED connections
shared = composio.connected_accounts.list(
account_type="SHARED",
user_ids=["user_creator"],
)
composio-client bumped from 1.38.0 -> 1.39.0 so the generated typed
client carries the Experimental TypedDicts for link.create,
tool_router.session.link, and connected_accounts.patch.
Tests cover: experimental block forwarding (link + authorize),
no-op when omitted, empty-list preservation, typed error mapping for
the PRIVATE-with-ACL case, experimental.update_acl body construction +
deny-list handling + ValidationError when no fields are provided +
ValidationError when called without a bound client, and
list(account_type="SHARED") flat-filter delegation.

Also makes multiAccount fields optional in ToolRouterUpdateSessionConfig
(PATCH semantics) and adds a PATCH-safe transform that doesn't inject
create-time defaults.

Bring `link()` to parity with `initiate()` so the duplicate-connection
guard moves with customers as Composio-managed redirectable-OAuth
callers migrate from `connected_accounts/create` to
`connected_accounts/link` (SEC-339).
- TS: add `allowMultiple?: boolean` to `CreateConnectedAccountLinkOptions`.
`link()` now pre-flights `connectedAccounts.list({ statuses: ['ACTIVE'] })`
and throws `ComposioMultipleConnectedAccountsError` when an active
connection exists and `allowMultiple` is not `true`.
- Python: add `allow_multiple: bool = False` to `connected_accounts.link()`
with the same guard and the same `ComposioMultipleConnectedAccountsError`.
- Tests: existing `link()` tests now mock `list` returning empty (default
no-existing-connection path); new tests cover the raise path and the
opt-in `allowMultiple=True` skip path. Also add multi_account parity
tests on the Python tool_router create() to mirror the TS suite.
Behavior change is intentional and patched separately with
`.changeset/sdk-link-allow-multiple.md`. The user-facing changelog entry
is split into a separate docs PR alongside the sandbox-size docs.

Expose `workbench.sandboxSize` (TypeScript) / `workbench.sandbox_size`
(Python) on `ToolRouter.create()` so callers can pick the workbench
sandbox compute tier (`standard`, `medium`, `large`, `xlarge`).
Optional; the server defaults to `standard` (1 vCPU / 1 GB) when
omitted, so existing callers keep current behavior.
- Bump stainless clients to pick up the field on the wire:
- `@composio/client` 0.1.0-alpha.66 -> 0.1.0-alpha.67
- `composio-client` 1.33.0 -> 1.34.0
- TS: extend `ToolRouterCreateSessionConfigSchema.workbench` with
`sandboxSize` and forward it as snake_case `sandbox_size`. Export
`SandboxSize` type and `SandboxSizeSchema` zod enum.
- Python: extend `ToolRouterWorkbenchConfig` TypedDict with
`sandbox_size` and forward it on the create payload. Export
`SandboxSize` literal alias.
- Changeset: `@composio/core` patch.
- Tests: cover the snake_case forwarding and zod enum rejection.
Docs (Configuring Sessions / Workbench / changelog) are split into a
separate PR so they can land alongside the SDK release.

## Summary
Automatic tool file upload/download for `file_uploadable` fields is
**off by default** in TypeScript and Python. Callers must explicitly opt
in, and uploads from local paths are constrained by a fail-closed
allowlist.
## Changes
- **Removed (breaking):** `autoUploadDownloadFiles` (TS) /
`auto_upload_download_files` (Python) — the legacy default-on flag is
gone, not just deprecated.
- **New opt-in:** `dangerouslyAllowAutoUploadDownloadFiles` (TS) /
`dangerously_allow_auto_upload_download_files` (Python). When `true`,
`tools.get(...)` collapses `file_uploadable` schemas to `{ type:
'string', format: 'path' }` and the SDK stages local paths/URLs at
execute time.
- **New:** `fileUploadDirs?: string[] | false` — fail-closed allowlist
for local upload paths. `undefined` → `[<home>/.composio/temp]`; `false`
→ reject all local paths (URLs / `File` objects unaffected); explicit
`string[]` replaces the default. Components are matched on a path
boundary after `realpath`.
- **New:** `fileDownloadDir?: string` — directory where
`file_downloadable` results are staged.
- **New:** `beforeFileUpload` hook receives `source: 'path' | 'url' |
'file'` (TS) / `'path' | 'url'` (Python) so it can branch on input type.
- **New (TS):** when auto-upload is **off** and an LLM-driven
`tools.execute` is called against a tool with `file_uploadable` inputs,
the SDK emits a one-shot warning per tool slug pointing at
`composio.files.upload()` for manual staging.
## Migration
To restore previous behavior:
```ts
new Composio({
apiKey: process.env.COMPOSIO_API_KEY!,
dangerouslyAllowAutoUploadDownloadFiles: true,
// Optional: tighten the allowlist beyond the default ~/.composio/temp
fileUploadDirs: ['/srv/uploads'],
});
```
```python
Composio(api_key="...", dangerously_allow_auto_upload_download_files=True)
```
If you previously passed the legacy flag, remove it. There is no
transitional warning — TS and Python both reject the unknown property at
the type/keyword-arg level.
## Versioning
| Package | Bump |
| ------- | ---- |
| `@composio/core` | minor |
| `composio` (Python) | minor |
| Other `@composio/*` packages | patch (via changesets
`updateInternalDependencies: "patch"`) |
See
`docs/content/changelog/04-24-26-legacy-auto-upload-config-removal.mdx`
for the full migration writeup.
## Summary
Security-hardening for automatic file upload in `@composio/core` (patch
release per changeset).
### Changes
- **Default denylist** for local paths before auto-upload /
`files.upload`: blocks common credential directories (e.g. `.ssh`,
`.aws`) and credential-like filenames (e.g. `.env`, default SSH private
keys). Resolves symlinks when the path exists.
- **Config:** `sensitiveFileUploadProtection`,
`fileUploadPathDenySegments` on `Composio`.
- **`beforeFileUpload`** hook (e.g. with `composio.tools.get` /
`tools.execute`): rewrite path, return `false` to abort, or throw.
- **Errors:** `ComposioSensitiveFilePathBlockedError`,
`ComposioFileUploadAbortedError`; file modifier errors exported from
`@composio/core` errors entry.
- **Changeset:** patch bump for `@composio/core`.
### Notes
- URLs and `File` blobs are not subject to the path denylist
(unchanged).
- Opt out of path checks only if required:
`sensitiveFileUploadProtection: false`.
### Tests
- `pnpm test` in `ts/packages/core` (799 tests) passed locally before
commit.

Add the `enable` boolean field to workbench configuration in both
TypeScript and Python SDKs. When set to false, the session excludes
COMPOSIO_REMOTE_WORKBENCH and COMPOSIO_REMOTE_BASH_TOOL, strips
workbench-related prompt lines, and rejects direct workbench calls.
Defaults to true for full backwards compatibility.
