Serial waiting adds latency without supplying new information when each review uses independent inputs. Dispatching unrelated reviews together preserves their individual evidence while permitting parallel execution.

Claims of completion require verifiable artifacts. The decisive requirement here is to launch independent specialists concurrently. An auditable code-review deliverable does not shorten three unrelated review calls when they are still dispatched serially. Change scheduling so independent requests can run concurrently.

Checking authorization before sending references is necessary for privacy, but does not make independent reviews run faster. The three review tasks already have unrelated inputs; executing them one after another adds their durations. Dispatch independent jobs concurrently while preserving each result's owner and scope.

Delegation budgets must bound execution, not silently convert an incomplete investigation into success. Although useful elsewhere, it is not the direct mechanism to avoid unintended broad tool inheritance.

Comments and role descriptions do not override actual SDK tool capability inheritance. A developer who expects no tools must explicitly configure the appropriate restriction and test the effective allowed tools; otherwise a specialist may retain more access than intended.

Delegation is a tool execution capability, not just a preference conveyed in instructions. The scenario instead requires a way to avoid unintended broad tool inheritance.

Asking the model to conceal unauthorized data after receipt does not enforce a tenant or requester access boundary. The coordinator must validate entitlement before a private file reference reaches the delegated context.

A structured coding handoff helps validate a patch, but it does not prevent a subagent from seeing an unauthorized customer's file reference. Privacy checks must run before delegation and retrieval, not only when evidence is returned. Filter the input references and enforce tenant-scoped retrieval permissions at execution.

A subagent receives the context supplied at invocation, not an automatic copy of all coordinator history. The decisive requirement here is to apply authorization before propagating retrieved context.

A narrow tool set limits what the delegated worker can execute, but it cannot rescue an assignment that says only 'look into this'. The failure is underspecified research scope and completion criteria. Give the specialist the exact question, bounded evidence context, required output and checks by which its result will be accepted.

A short cited handoff is useful after research completes, but it does not tell a newly spawned specialist what problem it is supposed to investigate. The vague instruction invites unfocused work. Supply a concrete objective, task boundaries and expected evidence before delegation; then require a concise sourced report.

Separate scratch contexts prevent experiments from contaminating each other, but starting additional isolated agents with the same vague objective merely reproduces the ambiguity. Define a bounded research contract and success criteria for the existing invocation instead of multiplying underspecified investigations.

Reducing the context passed to a specialist can prevent irrelevant data exposure, but it cannot grant the specific file-read capability this agent lacks. Verify the requested file is in scope and configure the effective read permission, while preserving restrictions on unrelated paths and all write operations.

Isolation prevents one experiment's tentative edits and reasoning from leaking into another test. The proposed option cannot provide the specific “Configure a narrowly scoped authorized tool set for that subagent” behavior that the case requires. Tool access is a host-enforced capability boundary, not something fixed by merely asking the model to behave.

Broadening the subagent into an unrestricted administrator violates least privilege and does not solve a narrowly authorized file-read need. The correct response is to configure the required read capability for the approved file while maintaining explicit restrictions on other resources and write operations.

Isolating scratch branches helps prevent conflicting experiments from overwriting one another. The synthesis worker here is not doing an experiment: it needs findings from an already completed search. Pass concise conclusions and their evidence locations so it can synthesize without inheriting the entire tool transcript.

Agent instructions alone cannot guarantee a read-only boundary when side-effecting tools remain available. The proposed option cannot provide the specific “Pass concise structured findings and supporting citations instead of the full search transcript” behavior that the case requires. Selective context passing keeps important evidence without consuming the subagent's budget on irrelevant history.

Explicit completion metadata lets the coordinator distinguish done, partial and failed delegated work. The direct remedy is “Pass concise structured findings and supporting citations instead of the full search transcript”, which the alternative does not itself accomplish. Selective context passing keeps important evidence without consuming the subagent's budget on irrelevant history.

Unrestricted writes to a single shared tree defeat the requirement for isolated experiments. One experiment could overwrite another or alter production files. Isolate scratch contexts and enforce workspace permissions separately instead of expanding write access.

A structured completion status makes a worker's outcome auditable, but two experiments can still change each other's workspace even when both return perfect status records. The stated requirement is independent execution. Give each experiment a separate scratch context and enforce isolation from shared production state.

Provenance must identify the exact evidence inspected, or later synthesis may misattribute facts. Here, a coordinator needs isolated experiments that should not modify shared state. Spawn separate bounded subagent tasks with independent scratch context. Isolation prevents one experiment's tentative edits and reasoning from leaking into another test.

Applying the stale patch without checking the current base can overwrite revision 18 or silently discard intervening changes. A coding agent's confidence in its diff does not prove that the target branch is unchanged. The coordinator must verify the base revision before merging.

A narrative completion claim does not establish repository state. The patch may have been correct against revision 17 but incompatible with the updated revision 18. Read and validate the current tree or use a versioned merge precondition rather than relying on the agent's report.

Additional context tokens do not verify the current state of the shared branch. The issue is a concurrent revision change, which requires a deterministic base-version check and review of intervening commits. Skipping that check risks lost updates and a false successful merge.

Versioned evidence references protect citation accuracy, but they do not tell the coordinator whether a delegated task finished or stopped halfway. The missing machine-readable field is a completion state. Return done, partial or failed status together with blockers, results and evidence identifiers so a partial report cannot be mistaken for success.

A coordinator should control redundant delegation to conserve time and prevent divergent answers to identical work. Here, a task result contains findings but no machine-readable completion status. Return structured status, outcome, blockers and evidence identifiers. Explicit completion metadata lets the coordinator distinguish done, partial and failed delegated work.

A precise delegated contract controls relevance and supports objective verification of the subtask result. The required action is “Return structured status, outcome, blockers and evidence identifiers”; the other measure addresses a separate concern. Explicit completion metadata lets the coordinator distinguish done, partial and failed delegated work.

Deduplicating repeated subtask requests reduces redundant work, but the task is already complete and its citations refer to the wrong document revision. Match the returned claims to immutable document IDs and revision hashes; rerunning fewer tasks would not repair evidence provenance.

A precise delegated contract controls relevance and supports objective verification of the subtask result. The direct remedy is “Pass immutable document identifiers and revision information with the findings”, which the alternative does not itself accomplish. Provenance must identify the exact evidence inspected, or later synthesis may misattribute facts.

Tool access is a host-enforced capability boundary, not something fixed by merely asking the model to behave. Here, a delegated analysis finishes but its source citations point to a different document version. Pass immutable document identifiers and revision information with the findings. Provenance must identify the exact evidence inspected, or later synthesis may misattribute facts.

A precise delegated contract controls relevance and supports objective verification of the subtask result. This is not a substitute for “Deduplicate equivalent subtask requests before spawning another agent”; that control is necessary in the stated circumstances. A coordinator should control redundant delegation to conserve time and prevent divergent answers to identical work.

Tight tool permissions are important for safe delegation, but they cannot identify when two authorized assignments ask the same question and consume the same context. Check stable task inputs and pending work IDs before spawning another agent, and reuse or reconcile a verified existing result instead.
