Agent TaskGraph Protocol v0.8.0-beta.11

What changed

• Runtime is now an explicit Owner choice. Model, effort, yolo, or a generic start approval cannot silently select native instead of HAPI.
• PROJECT.md can retain a preferred runtime and machine for recommendation order without treating that preference as launch authorization.
• New structured task manifests and scripts/prepare-task.py atomically generate Goal, ledger, context, and dispatch files.
• The pre-dispatch state gate validates reserved roles, requested runtime, Git baseline, branch, clean registered worktree, pending identity state, and STATUS visibility before spawn.
• Inbox preparation is visible, with a five-minute time-to-first-worker escalation rule.
• HAPI test fixtures no longer inherit a live HAPI_API_URL and accidentally authenticate against the real Hub.

Compatibility

Existing active batches remain pinned to the protocol version recorded in PROJECT.md. Apply beta.11 to a new batch; do not rewrite completed historical evidence.

Validation

• 13-stage smoke suite passed
• 15 HAPI helper tests passed
• Codex plugin validation passed
• Claude plugin validation passed
• Skill quick validation passed

Agent TaskGraph Protocol v0.8.0-beta.10

Highlights

• Adds a 30-second animated walkthrough to the English and Chinese READMEs.
• Demonstrates clarification, frozen specifications, dependency graphs, durable roles, verified worker sessions, evidence receipts, and independent review.
• Includes the full-quality 1080x1080 silent MP4 as a Release asset.
• Keeps generated HyperFrames project files out of the source repository.

Verification

• ./tests/smoke.sh
• python3 -m unittest discover -s tests -p "test_*.py"
• Shell syntax and release manifest version checks

Agent TaskGraph Protocol v0.8.0-beta.4

What's new

• Native-first Claude Code and Codex runtimes, with HAPI retained as an explicit opt-in adapter
• Visible macOS Terminal sessions for workers and reviewers, including dry-run command previews and PID-backed launch evidence
• Source Baseline Gate requiring a reproducible Git baseline and isolated worktrees for complex dispatch
• Dispatch Preview Gate showing roles, dependencies, writes, runtime, model, effort, permissions, worktrees, Goal refs, and launch commands before sessions open
• Stable task:<id> Goal refs that survive queue state moves
• Deterministic graph validation for dependency ancestry, cycles, route targets, dynamic queue paths, and parallel write conflicts
• Deterministic state validation across queue directories, Goals, ledgers, and STATUS
• Natural-language usage guidance in the English and Chinese READMEs
• Portable CI coverage for the macOS Terminal launch path

Verification

• ./tests/smoke.sh passed all 11 groups locally
• Skill structure validation passed
• OpenAI/Codex plugin validation passed
• claude plugin validate ./plugins/agent-taskgraph passed
• GitHub Actions verification is required for this release

Upgrade

git pull --ff-only
./install.sh --status
./tests/smoke.sh

Symlink installs do not require reinstalling. Start a new Claude Code or Codex session so the updated Skill instructions are loaded.

Beta scope

This release still does not provide an unattended scheduler, deterministic ready-node calculator, queue-transition CLI, automatic merge, or automatic release. Platform directory review and listing remain controlled by OpenAI and Anthropic.

v0.8.0-beta.4 supersedes v0.8.0-beta.3, whose GitHub Actions run exposed a Linux portability issue in the Terminal launcher smoke fixture.

Agent TaskGraph Protocol v0.8.0-beta.3 (superseded)

Superseded by v0.8.0-beta.4.

The protocol changes in this release were valid, but its GitHub Actions run exposed a Linux portability issue in the macOS Terminal launcher smoke fixture. Use v0.8.0-beta.4, which contains the same dispatch safeguards plus the portable CI fix.

Included changes

• Native-first Claude Code and Codex runtimes with HAPI as an opt-in adapter
• Visible worker and reviewer Terminal sessions
• Source Baseline and Dispatch Preview gates
• Stable task:<id> Goal refs
• Deterministic graph and state validators
• Simpler natural-language usage documentation

Agent TaskGraph Protocol v0.8.0-beta.2

What's included

• Self-contained OpenAI/Codex and Claude Code plugin package under plugins/agent-taskgraph/
• Claude Code marketplace catalog at .claude-plugin/marketplace.json
• Public Beta README guidance for standalone, skills.sh, Codex, and Claude distribution
• Package drift checks in tests/smoke.sh
• Version and manifests aligned at 0.8.0-beta.2

Verification

• ./tests/smoke.sh
• Codex plugin validation passed
• claude plugin validate ./plugins/agent-taskgraph passed

Scope

This is a Public Beta distribution release. It still does not provide an unattended scheduler, deterministic graph validator, automatic merge, or automatic release. Platform directory submissions remain subject to their respective publisher review processes.

Previous protocol release: v0.8.0-beta.1.

Agent TaskGraph Protocol v0.8.0-beta.1

Agent TaskGraph Protocol v0.8.0-beta.1

Private Beta release for Claude Code and Codex users.

Included

• Spec-first intake with owner clarification and frozen task graphs
• PMO, worker, reviewer, ledger, evidence, and Human Gate protocols
• Conflict-safe install and explicit .agent-queue to .agent-taskgraph migration
• Codex/HAPI log helpers and conservative cleanup
• Apache-2.0 license
• Version metadata and non-destructive update notification via ./install.sh --check-update

Boundaries

• Runtime dispatch still depends on the actual Codex, HAPI, or Claude capabilities available in the host
• No unattended scheduler, deterministic graph validator, or automatic merge/release
• Review the repository README before using this beta in a production project
