+# Agent teams extension
+
+Keep team business logic in this independently installable package. Runtime code
+imports public `deerflow_extension_api` contracts and its declared LangChain
+dependency; do not import host `app.*` or `deerflow.*` internals. Browser code is a
+manifest-listed native module with no host React dependency.
+
+Every storage operation is owner-scoped. Native mentions use Gateway's stamped
+runtime identity and delegated capability, never an owner from mention content.
+Thread sharing is not team sharing. Keep peer content on human-message channels.
+
+Persist run input and idempotency keys before admission. Serialize by thread and
+record a terminal result and its follow-up receipt in one SQLite transaction.
+Unknown admission outcomes must retain ownership of the pending job. Never
+automatically approve interruptions, infer success from a terminal run alone, or
+serialize a host capability. Only an authenticated action or native mention
+rebinds after restart.
+
+Reconnect ensures every member thread before persisting readiness, serialized
+with deletion and task updates. Count only requests toward the 100-request cap;
+each request can produce at most one receipt, bounding the ledger to 200 entries.
+Browser member labels must remain unique after trimming and truncation to the
+backend character/UTF-8 byte limits. Use host theme tokens for action colors.
+Validate user-entered team names, goals, tasks and clarification answers against
+both backend bounds without truncating the draft. Native mention labels must fit
+the host's 120 UTF-16-unit limit; keep routing IDs independent of display labels.
+
+Ordinary human-input artifacts end runs successfully without a graph interrupt.
+Keep unanswered requests waiting; persist text-response inputs and idempotency
+keys before ordinary admission, and retain their message/run IDs for result
+attribution. Graph interrupts still use explicit resume. Do not admit new work
+over either unresolved input path. Peer handoffs inherit the first unfinished
+source-thread occupant only when it has begun admission and is not waiting for
+input; later queued jobs never supply the parent or chain budget.
+
+Run the backend plugin tests and the browser check documented in README.md after
+changes. The preview fixture has synthetic authentication and must remain
+loopback-only; never use it as a deployed Gateway.

+# Agent teams — independent plugin
+
+Let existing full Custom Agents work together through directed requests and a
+shared record. Each member gets its own persistent conversation, bound to its
+Custom Agent name. Ordinary Agent configuration, tools, skills, memory,
+checkpoints and approval rules remain in effect. There is no mandatory supervisor.
+
+Requires DeerFlow's native mention-provider and full Agent run-control contracts
+(`deerflow-extension-api >= 0.2.5`). This package is opt-in, with no core team
+feature or frontend rebuild.
+
+## Install
+
+From `backend/`, install the trusted local package:
+
+```sh
+uv run deerflow extensions install ../examples/deerflow-extension-agent-teams --yes
+```
+
+Set the deployment-owned entry in `config.yaml`, then restart Gateway:
+
+```yaml
+plugins:
+ - use: deerflow_extension_agent_teams:install
+ enabled: true
+ config:
+ enabled: true
+ storage_path: /var/lib/deerflow/agent-teams.sqlite
+```
+
+Mount a persistent writable directory. The package contains its browser assets;
+the host serves the manifest-listed files. Both switches, package upgrades and
+the path require a Gateway restart. This SQLite example supports **one Gateway
+process per database**. A second service instance refuses to start against the
+same database; it cannot dispatch through its actions or middleware.
+
+## Use
+
+1. Create at least two Custom Agents in **Agents**. Members can delegate work to
+ each other using this plugin's collaboration tools. Usually no extra setup is
+ needed; if an Agent has a tool-group allowlist, include `extensions` in it.
+2. Open **Agent teams** in the sidebar, or
+ `/workspace/extensions/community.agent-teams/teams`.
+3. Set a name and goal, search your existing Agents by name or description, and
+ select 2–8 members. The plugin reads the authenticated public `/api/agents`
+ endpoint on its asset Gateway, preserving deployment prefixes. Catalog errors
+ have a retry control and never silently fall back to invented agents. The
+ roster is fixed for this team; create another team for a different composition.
+4. In the team composer, type `@` and select one or more members, or click a member
+ in the sidebar. Recipient chips determine routing; unselected plain-text names
+ do not. Each selected member receives a separate request. Use Send or
+ Command/Ctrl+Enter; Enter inserts a newline except while choosing a mention.
+ The normal host chat's native `@` picker remains available too.
+5. A member can call `send_member` to ask a peer for work. Its result returns to
+ the requesting conversation in a later turn. `read_team_context` reads the
+ current shared record; members do not synchronously block or poll each other.
+ Handoffs inherit the executing request's parent and chain budget. Later queued
+ requests do not change that attribution; an ordinary member chat with no
+ executing team request starts its own chain.
+6. The activity feed pairs requests with their results, identifies the sender and
+ recipient, and shows peer handoffs and return status. It updates automatically
+ while visible, preserving unsent drafts, expanded details and approval input.
+ Unchanged revisions return a small response. Task details open the full member
+ conversation or cancel an active task. Files stay in the original conversation.
+7. When a task or its result receipt needs input, expand its details. An ordinary
+ clarification shows its question and accepts a text answer, submitted as a
+ human message. A graph interrupt instead requires inspection in the member
+ conversation and an explicit JSON response. The plugin never generates
+ approvals. Respond through the team page while it owns the request so it can
+ track the continued run. Unanswered questions do not produce completed-result
+ receipts. Cancelling keeps checkpoints; unresolved questions and interrupts
+ block subsequent new tasks in that conversation until answered.
+8. After restarting Gateway, choose **Manage → Reconnect** in an active team.
+ Persisted jobs retain their inputs and idempotency keys; active runs are
+ reconciled instead of blindly restarted. Reconnection also recreates a missing
+ member thread with its recorded Agent binding. If creation was interrupted,
+ the team becomes ready only after all member threads are ensured successfully.
+ Existing threads stay unchanged.
+
+A new authenticated native mention can also reconnect its team. Existing queued
+jobs then continue under that caller's current delegated capability.
+
+Deleting a finished team removes its plugin records, not its Agent conversations.
+Cancel/finish all queued, running and interrupted jobs first. Each user has their
+own teams. Sharing a host conversation does **not** share its team's private data.
+
+## Execution and limits
+
+- Full Agent runs use the host-bound `AgentRuns` capability, never `task()` workers
+ or raw model invocation. Capabilities are process-local, never stored in SQLite.
+ Gateway rechecks the user, permission ceiling, current permissions and thread
+ access on every call. PAT/internal callers without this capability cannot run teams.
+- Different member conversations can run concurrently; admissions are bounded to
+ eight active plugin jobs shared by all owners in this process, without per-owner
+ quotas or fair scheduling. A busy owner can keep other owners' jobs queued.
+ The tick loop holds a shared lock while checking/admitting jobs, with a ten-second
+ timeout per job advancement; slow host calls delay create, send, cancel, resume,
+ delete and reconnect for all teams until the pass releases the lock. Per-owner
+ fairness and finer-grained locking are outside this example's current scope.
+ Each conversation is serialized, including result
+ receipts. A busy host conversation stays queued without cancelling its run.
+- Each owner can have 20 teams. A team accepts at most 100 requests, with separate
+ space for up to 100 result receipts (200 total job entries); a handoff chain
+ accepts at most 12 requests. Start a new user request for another chain, or a
+ new team when the team's capacity is exhausted. Agent-to-Agent loops therefore
+ cannot grow without a bound.
+- Team names accept up to 80 characters / 160 UTF-8 bytes; goals accept up to
+ 2,000 characters / 4,000 UTF-8 bytes. Tasks and clarification answers accept
+ up to 4,000 characters / 8,000 UTF-8 bytes. The UI validates both bounds before
+ submission and preserves oversized text for editing. Native mention labels
+ fall back to the member name when the combined team/member label exceeds the
+ host's 120 UTF-16-unit limit; selection still routes by team/member IDs.
+ Shared context contains
+ at most eight recent messages within a 24 KiB JSON budget, plus the goal and
+ roster. Final answers are capped at 6,000 UTF-8 bytes with a truncation notice.
+ Team storage retains the most recent 100 shared messages. Each new job also
+ keeps its bounded result independently, so context rotation does not erase its
+ activity card. Older installations fall back to retained messages; an unavailable
+ old result links to the original conversation. Compact request pages default to
+ 20 records. The UI requests up to 200 detailed entries (within the bounded team
+ capacity), and sends a revision to avoid retransmitting unchanged results. This
+ is a bounded working context, not a transcript archive.
+- Shared task text and peer results travel as human-message data with provenance,
+ never as framework system instructions. Only final text is shared automatically;
+ hidden reasoning, tool transcripts and attachment bytes are not copied.
+- Do not launch unrelated turns or manually compact a member conversation while
+ a team request is being collected. If its identifying checkpoint is gone or a
+ later human turn is detected, the plugin reports that the result cannot safely
+ be attributed and asks you to inspect the conversation.
+- Admission timeouts retain the exact input/key for idempotent recovery. Revoked
+ access or an ambiguous host failure disconnects the team without pretending
+ that its active jobs completed. Reconnect after resolving the cause.
+
+## Validation
+
+From `backend/`:
+
+```sh
+uv run pytest tests/test_agent_teams_plugin.py tests/test_extension_agent_runs.py tests/test_plugin_tools.py -q
+uv run ruff check ../examples/deerflow-extension-agent-teams
+uv run ruff format --check ../examples/deerflow-extension-agent-teams
+```
+
+The tests load the real extension and exercise owner isolation, directed requests,
+real ToolNode dispatch, mention middleware in the Lead middleware pipeline,
+host-compatible mention labels at the UTF-16 boundary with stable routing IDs,
+serialization, interrupts, cancellation, restart/reconnect (including incomplete
+creation), request capacity independent of receipts, ambiguous admission, and
+lifecycle locking. Host-run transport is controlled for deterministic tests.
+Clarification tests execute the host's real tool and middleware in an Agent graph,
+including repeated questions, peer/mention/result-receipt paths, lost response
+acknowledgements and restart. Queued-request regressions pin handoff attribution
+and the chain limit while the first request is running or awaiting admission acknowledgement.
+
+For a browser check, install the repo's frontend dependencies, then start the
+loopback-only fixture from `backend/`:
+
+```sh
+uv run python -m extension_test_fixtures.agent_teams_gateway 8197
+```
+
+In another terminal, from the repository root:
+
+```sh
+node examples/deerflow-extension-agent-teams/verify_browser.mjs
+```
+
+This drives packaged UI assets, real plugin routes, SQLite and graph checkpoints,
+with a synthetic identity and deterministic model. It verifies team creation,
+insecure HTTP without `crypto.randomUUID`, Shadow DOM, catalog failure/retry,
+search and selection, unique bounded member labels after truncation, Unicode
+character/byte validation with draft preservation for names, goals, tasks and
+clarification answers, accepted ASCII/CJK/emoji boundary inputs, keyboard
+mentions, task/result pairing, peer receipts,
+automatic conditional updates, draft/detail preservation, owner isolation,
+conversation navigation, mobile/dark layouts, delete-action contrast in both
+themes, ordinary clarification and text responses, reopening, deletion and disposal.
+The agent catalog and identity are synthetic; the peer fixture calls the real
+plugin handler through the public ToolContext contract. It does not claim production
+authentication or live-model coverage. Set `TEAM_PREVIEW_URL` for another port and
+optionally `TEAM_SCREENSHOT` to save a local screenshot outside the repository.
