Problem

In §4.6.2, the routing schema shows input as REQUIRED but output with no required marker:

routing:
  input:
    type: <agent|graph|stream>  # REQUIRED
    name: <component_name>      # REQUIRED
  output:
    type: <agent|graph|stream>
    name: <component_name>

However, step 4 of the composite agent's processing logic states:

  1. Collect the output from the output component.

If output is absent, the behavior is undefined. Should the composite agent:

  • Return the output of the input component directly?
  • Raise a ConfigurationError at load time?
  • Return an empty result?
  • Use the last component in the internal flow as the output?

Impact on Library Implementation

Validation code cannot decide whether to accept or reject a composite agent config missing output. Runtime code cannot know what value to return if output is absent but processing completes.

Decision Needed

Either mark output as REQUIRED in the schema table, or explicitly specify the fallback behavior when it is absent (e.g., "if output is absent, the composite agent returns the result of the input component").

## Problem In §4.6.2, the `routing` schema shows `input` as REQUIRED but `output` with no required marker: ```yaml routing: input: type: <agent|graph|stream> # REQUIRED name: <component_name> # REQUIRED output: type: <agent|graph|stream> name: <component_name> ``` However, step 4 of the composite agent's processing logic states: > 4. Collect the output from the output component. If `output` is absent, the behavior is undefined. Should the composite agent: - Return the output of the `input` component directly? - Raise a `ConfigurationError` at load time? - Return an empty result? - Use the last component in the internal flow as the output? ## Impact on Library Implementation Validation code cannot decide whether to accept or reject a composite agent config missing `output`. Runtime code cannot know what value to return if `output` is absent but processing completes. ## Decision Needed Either mark `output` as REQUIRED in the schema table, or explicitly specify the fallback behavior when it is absent (e.g., "if `output` is absent, the composite agent returns the result of the `input` component"). ## References - §4.6.2 — Routing (composite agent) - §4.6 — Composite Agents

auto/blocked-by-deps
PR blocked by an open issue dependency. Operator must close the dep (or remove the dependency link) before the merge driver can act. Auto-cleared by merge_drive when no open deps remain.

  
auto/ci-timeout
Most recent merge cycle hit CI timeout. Driver excludes this PR while last merge_cycle row is < 30 min old; label persists thereafter as visible history.

  
auto/claimed-implementer
Currently being processed by an implementer worker.

  
auto/claimed-merge
Currently being processed by the merge driver.

  
auto/claimed-reviewer
Currently being processed by a reviewer worker.

  
auto/driver-down
Merge driver heartbeat stale; pipeline halted. Closed automatically on next clean tick.

  
auto/invariant-violation
Detected master commit violating the strict merge invariant. Tracked as an issue (not a PR label); kept here for label completeness.

  
auto/last-attempt-tier-0
In-cycle escalation: most recent attempt ran at the Tier 0 slot (`tier-0`). Slot's model defined in .opencode/models/tiers.yaml.

  
auto/last-attempt-tier-1
In-cycle escalation: most recent attempt ran at the Tier 1 slot (`tier-1`). Slot's model defined in .opencode/models/tiers.yaml.

  
auto/last-attempt-tier-2
In-cycle escalation: most recent attempt ran at the Tier 2 slot (`tier-2`). Slot's model defined in .opencode/models/tiers.yaml. Gated behind IMPLEMENTER_ESCALATION_TIER2_ENABLED.

  
auto/last-attempt-tier-min
In-cycle escalation: most recent attempt ran at the Tier -1 slot (`tier-min`). Slot's model defined in .opencode/models/tiers.yaml. Suffix is ``-min`` (not ``--1``) so the Forgejo UI reads naturally.

Failing CI needs implementer attention.

  
auto/postmortem
Documenting a driver incident or rollback.

  
auto/ready-to-merge
Reviewer has APPROVED this PR and no later REQUEST_CHANGES is outstanding. The merge driver requires this label to even consider a PR for merging. Set by the reviewer worker on APPROVE; cleared on REQUEST_CHANGES.

  
auto/restart-throttled
Train repeatedly lost master-tempo races. Driver excludes via merge_cycle until cooldown elapses; label persists as visible history.

  
auto/revert
Revert PR backing out an invariant violation. Fast-tracked through the merge driver.

  
auto/sentinel
Sentinel PR duplicated from upstream into a personal fork by tools/duplicate_prs_to_fork.py for pipeline testing. Lives only in the fork; the canonical pipeline never sees it.

  
auto/stale-inactivity
No implementer activity for N days. Flagged for human review. Auto-cleared on next push to head branch.

  
auto/unstable
Repeatedly fails on current master (>= 3 ci-fail-on-rebased-sha releases in 12 h). Excluded from driver until human triage.
