Codex-Co-Engineer 3.3.0

Repository-side GitHub Release body for Codex-Co-Engineer 3.3.0.

Bounded runs on the five-tool catalog

3.3.0 adds a first-class bounded run: 1–8 independent assignments against one
immutable repository/base identity. The MCP catalog remains status,
delegate, task, tasks, and cancel. A run is additive parameters on
those tools, not a sixth tool.

  • Submit with delegate run (1–8 lanes). Direct mode, replay, fallback,
    merge, push, and create-PR are rejected on that path.
  • Inspect with status or task plus run_id.
  • Wait with wait_until: "decision_or_attention"; routine progress never
    wakes.
  • Latch attention and deliver one same-session run reply with task
    attention / run_reply.
  • Cancel or proof-bound cleanup with cancel run_id.

Provider and model are explicit on each assignment or filled from one named
data-only profile. VerificationPolicyV1 is the only executable command
catalog. Codex remains the only final acceptance and merge authority. Frozen
verified child deltas may be composed into one run-owned, single-parent,
non-authoritative candidate; that candidate is never the integration
authority.

Every 3.3.0 run Cloud lane must pin one exact already-pushed
provider-visible SHA in starting_ref. Individual 3.2.1 Cloud tasks still
treat starting_ref as optional.

The repository argument remains the literal MCP property repo:

{
  "task_id": "review-auth-refactor",
  "provider": "grok",
  "repo": "/absolute/path/to/git-worktree",
  "role": "review",
  "workspace_mode": "managed",
  "prompt": "Review the current branch and return concrete evidence.",
  "expected_duration_ms": 600000
}

Omit additive run fields to keep that exact 3.2.1 single-task path.

Wait on a run without waking on routine text:

{
  "run_id": "auth-split",
  "wait_until": "decision_or_attention"
}

Compatibility

  • The MCP tool count remains five.
  • Omitting run fields preserves exact 3.2.1 single-task, compact, wait-any,
    structured transport, DSH Muse default, and Ox Alpha selector behavior.
  • Direct mode remains available only for 3.2.1 single-task delegate.
  • Run submissions never use direct mode.
  • Gate B (context-efficiency) and Gate C (credit economics) stay advisory.

Out of scope

3.3.0 does not add semantic memory, cross-run search, learned routing,
protected-branch integration, or automatic garbage collection.

Validation

npm --prefix plugins/codex-co-engineer test
node scripts/validate-release.mjs
npm --prefix plugins/codex-co-engineer run setup:check

This document does not publish live provider transcripts or host
measurements.

Maintainer publication

After the exact candidate is reviewed, replace EXACT_REVIEWED_MAIN_SHA with
that immutable commit and verify it before publishing:

test "$(git rev-parse HEAD)" = "EXACT_REVIEWED_MAIN_SHA"
gh release create v3.3.0 \
  --target EXACT_REVIEWED_MAIN_SHA \
  --title "Codex-Co-Engineer 3.3.0" \
  --notes-file docs/releases/v3.3.0.md

This document does not authorize tagging, pushing, or release publication.
