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.
