## Thinking Path > - Paperclip lets people assign work to AI agents. > - Native task creation can start the assigned agent as soon as the task is ready. > - The default assignee is the agent that creates the task. > - An agent can omit the requested teammate, create work for itself, and reassign it too late. > - The server already supports setting the requested agent and project during creation. > - This pull request makes those fields and the early-start risk clear in both tool catalogs and the delegated-task example. > - The benefit is clearer guidance for the existing delegation contract. ## Linked Issues or Issue Description Related: #13281. **What happened?** An observed delegation attempt called `create_task` with only a title and retry key. The task used the documented current-agent default and started work before a later reassignment. The server honored its contract. The original failed QA result remains failed. **Expected behavior** When a user names an existing teammate and project, the agent should put their exact IDs in `assigneeActorId` and `projectId` during task creation. The requested worker can then start with the correct task ownership and project. **Steps to reproduce** 1. Ask an agent to create work for a named existing teammate in a named project. 2. Create a ready task with only its title and retry key. 3. Observe that the creating agent is assigned and can start before a later reassignment. This is a guidance mitigation for agent tool misuse. It does not change the default or enforce model compliance. A fresh deployed qualification is still required. ## What Changed - Explain initial teammate and project selection in the canonical `create_task` description and its two field descriptions. - Add a representative delegated-task call with an explicit agent, project, and saved plan. - Synchronize the same three descriptions in the sibling semantic-action catalog. Keep its schema constraints intact. - Keep the global execution prompt byte-for-byte equal to the base. Revision `paperclip-execution.v8` already directs the agent to create delegated work with the teammate ID. - Refresh the generated catalogs, seeded catalog identity, and protocol manifest. - Make the collaboration contract test use the declared scenario example, as the general contract test already does. Retain separate live-example validation and strict scenario input checks. ## Verification - All 79 existing native controls passed across `chat-project-tools`, `paperclip-runner-tool-authority`, `task-creation-backlog`, and `tool-receipt-recovery`. These cover alternate-agent readback, current-agent defaults, backlog holds, company boundaries, and dispatch recovery after commit. - All 108 protocol-action, semantic-catalog, catalog-doc, runtime-context, and collaboration checks passed. All 11 contract fingerprint checks passed. - The original CI collaboration-test failure reproduced locally before correction: the test sent live-only fields to the older scenario schema. After selecting the declared scenario example, all 13 collaboration cases passed. Malformed titles, undeclared project fields, and arbitrary unknown fields still reject. No schema or live example was changed for this correction. - Generator checks passed for semantic contracts, the semantic-action catalog, operation groups, and protocol coverage. - `pnpm -r typecheck`, `pnpm build`, `node scripts/check-maps.mjs`, and `git diff --check` passed. - A structural comparison confirms that types, required fields, lengths, modes, permissions, outputs, and defaults are unchanged on both catalog surfaces. - No new text-matching tests were added. These local checks passed again after the global prompt was restored. Fresh exact-head Greptile and Paperclip reviews are both 5/5 with no actionable findings. [Current-head CI](https://github.com/paperclipai/paperclip/actions/runs/41565349812) completed successfully on `2e5f93e122191e17b316a7780a74ff404fc468f3` (attempt 2), with all 49 workflow jobs successful. - Current-head CI first failed only the unchanged native-process retention case at its original five-second limit. The shard passed 2,130 other tests and skipped eight. One unchanged local Node 24 control passed. The original test and retention dependency blobs match the base. The exact timeout cause remains unknown. No source, assertion, or time limit changed. One authorized recheck of only that runner shard and its normal final gate passed. The recheck passed 2,131 tests and skipped eight. The other 47 successful job results were carried forward with their original start and finish times. - The prior head `42207172dd4bc376dab880dbccb2c698acccf6c4` passed all 49 CI jobs and fresh 5/5 reviews. Its first CI attempt lost one server runner to a reported shutdown. One authorized retry of only that lost shard and its normal gate passed with unchanged assertions and time limits. The original failure and recovery remain recorded. - A normal merge of that prior head was rejected by the base policy because the global prompt required a code-owner review. This revision drops that optional global change. No policy override or bypass was used. - The new catalogs have semantic catalog digest `sha256:5af904b7fc088509b98dde41611c042ff3c22c881e252190817978de0d1b733a`. The authorized `create_task` operation digest is `sha256:f5dad10c7969680d91514603966705ac09ceaa3f2cff21fd6c199e2de0d7a63d`. - A new run can report admitted prompt revision v8 and its digest. The ordinary run-profile tool fingerprint does not hash these descriptions. Source/Core and matching provider-pack identity prove deployed code, not model delivery or compliance. A fresh campaign with new agents is still required. - No model run or deployed acceptance was performed for this source change. The original failed qualification remains failed. This tool-guidance change is a mitigation hypothesis. ## Risks The longer tool descriptions change the catalog identity. A model can still omit a requested field. The global prompt remains v8. Existing assignment, authorization, wake, replay, and session behavior stays intact. A new campaign is required because a stored provider session can retain old tool declarations. A native-process retention test has a recurring five-second timeout on unchanged code. One unchanged local Node 24 control passed. This does not prove CI reliability or explain the timeout. No timeout or assertion was changed. ## Model Used OpenAI GPT-6 through Codex with reasoning and code execution. The runtime does not expose a more specific model identifier or context-window size. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: Paperclip <noreply@paperclip.ing>
PRP v1/v2 Contract
The JSON Schema files in schemas/ are the language-neutral source of truth for
Paperclip Runner Protocol versions 1 and 2. The fixtures in fixtures/ define
accepted and rejected compatibility cases.
Compatibility
protocolVersion,fixtureVersion, andevent.schemaVersionare required.- A consumer fails closed when a required version or schema discriminator is not supported.
- A v1 envelope can contain an unknown optional property when its schema marks that object as extensible.
- A consumer ignores an unknown optional property until a later contract gives it meaning.
- A required field, enum value, or typed structured-input field is not optional.
- Question and answer identifiers are stable across the provider boundary.
- Peers negotiate the highest mutually supported protocol version. Existing v1 runners remain compatible but cannot receive v2-only session-goal commands.
The unknown-optional-fields.json fixture must be accepted. The
unsupported-required-version.json fixture must be rejected.
Session goals (v2)
PRP v2 adds a provider-neutral durable session-goal lifecycle. Every v2
capability snapshot includes sessionGoals, even when its availability is
unsupported or policy_disabled. Paperclip sends controls only when the
negotiated capability advertises the corresponding action.
Commands:
session.goal.getsession.goal.setfor objective, status, and optional token budget changessession.goal.clear
Events:
session.capabilities.updatedsession.goal.snapshotsession.goal.updatedsession.goal.cleared
Goal state is separate from Paperclip's company/business goal hierarchy. The
snapshot distinguishes the durable status from workingNow, because an active
goal can be idle between autonomous turns. A runner emits the full capability
and authoritative snapshot after every session open or resume. Missing v1
capability is unsupported; clients do not infer support from an adapter name.
Harness credential updates
auth.credentials.updated is a P0 runner event available in the v1, v2, and v3 event
schemas. Its payload uses paperclip.auth.credentials.updated.v1 and contains
only provider, bindingId, revision, and detection. No tokens, account
identifiers, credential paths, or credential fingerprints are permitted.
An updated consumer opts in with observeCredentials: true in run.prepare,
before session.open. The bundled runner transport opts in for fresh sessions;
set its observeCredentials option to false to disable observation for a
fresh session. Older hosts that omit the field receive no new event. Consumers
must update their schemas before opting in: an event-enum addition is not an
unknown optional property. Existing runner binaries ignore the optional flag
and do not provide observation; absence of an event does not establish support.
The current Unix runner observes native Codex's managed CODEX_HOME/auth.json
and the Codex/Grok ACPX session homes. It uses a non-recursive directory watch
plus a one-second polling fallback, so atomic file replacement is handled.
Grok's initial inline subscription credential is the baseline, allowing a
refresh during launcher startup to be detected. A first valid credential file
without a prior baseline establishes the baseline without claiming a refresh.
Account identity changes also emit updates, even when token values stay the
same, and establish the baseline for later refreshes on the new account.
Hosts must evaluate the current credential through their private credential
channel and account checks; the event does not authorize an account switch.
Metadata-only changes, partial writes, and deletion do not emit updates.
Unsupported harnesses and refreshes retained only in memory need
their own observer or native-hook integration; adding this event does not make
them observable.
bindingId: "harness-auth" identifies the selected harness authentication
within the envelope's normalized session. Revisions increase for that binding
and survive runner restarts and warm run attachments. The baseline fingerprint
and pending event are persisted together in a private runner state file. Source
retries retain the same event identity until the durable PRP outbox accepts it.
Hosts should commit an idempotent reaction or durable work item through
onCommittedEvent before returning and advancing the cumulative ACK.
The bundled transport exposes onCredentialsUpdated(event) for this commit.
It awaits the callback before ACK, including during warm idle, attachment, and
provider cleanup. Callback failures leave delivery unacknowledged for retry;
callbacks must therefore deduplicate by the original source event identity.
When configured, credential updates bypass the turn notification queue.
Paperclip commits them directly to the run log in a separate credential source
namespace, preserving the original PRP envelope and avoiding collisions with
the driver's normalized event sequence. A turn-only notification consumer
cannot reliably handle idle or cleanup updates; use this callback instead.
detection: "credential_store" reports an observed credential change, not proof
that an OAuth refresh succeeded. Multiple changes between observations can be
coalesced; this is not an audit of every refresh exchange. The schema also
allows native_hook for integrations with an explicit signal. Observation
continues during warm idle and checks at turn terminal and close boundaries,
including Grok's private refresh handoff after live-store cleanup. Retained
runner observations enter the durable outbox before a suspend or shutdown
command completes, without draining the provider backlog. A final check after
provider cleanup also enters the outbox and waits for the host ACK. The runner
retains its terminal recovery fence if that delivery fails.
The event authorizes no credential access or write on its own. A host that needs rotated token values must use a separately authorized handoff with its existing account-identity and freshness safeguards. The default Paperclip credential copy-back behavior remains in place.
Scope
The first provider descriptor and adapter fixture cover Codex only. The schemas for provider-neutral events and semantic receipts do not enable those actions. Discovery and authorization are separate contracts.
The conformance manifest records every source file and its SHA-256 digest. Run
pnpm generate:protocol-manifest from this package after a source change. CI
runs the same generator with --check to reject drift. This check also compiles
the JSON Schemas and validates every replay, question, and cross-language
conformance fixture against its declared schema.
The files in fixtures/replay/golden/ are deterministic reducer oracles. Each
accepted replay fixture has a complete session snapshot and a compact parity
summary. pnpm generate:replay-goldens updates them after an intentional
reducer change; package build and CI fail when they drift.
The files in fixtures/local-runner/scripts/ drive the package-local fake
harness. They cover successful, failed, interrupted, interactive, duplicate
terminal, process-cleanup, and oversized-frame behavior without starting a
production adapter.
runtime.activity.recorded is a P1 Runner event in v1, v2 and v3 with exactly
{ namespace, activityKey }. Both opaque identifiers contain 1–160 Unicode code
points and exclude C0 controls and DEL. namespace groups a producer's activity
types; activityKey names an activity within that group. Consumers use the pair
to select a response to activity in the run. The authenticated outer envelope
provides run and session identity, source sequence and emission time. Core resolves
the run's company, task and agent through its existing authorized run binding;
callers cannot supply those identities in the payload. Recording activity does
not independently verify the reported action or grant access to any resource.
The event uses the ordinary durable outbox, acknowledgement and replay contract.
Local clients capture an opaque context with paperclip-runnerd notification-context
before an operation and invoke record-activity CONTEXT NAMESPACE ACTIVITY_KEY
after success. Runner publishes its matching absolute executable as host-owned
PAPERCLIP_RUNTIME_NOTIFICATION_HELPER and the stable endpoint descriptor path
as PAPERCLIP_RUNTIME_NOTIFICATION_CONTEXT. Configured task environment cannot
override either value. Context is invalidated on warm attachment and process
recovery, so a caller cannot attribute a later completion to a different run.
