Full Changelog: v0.2.0...v0.3.0

agent-runtime-kit 0.2.0

Added

• Local SDK evolution agent example with runtime-backed direction analysis, architecture decision, reviewer stages, reports, and optional draft PR creation.
• Release-note collection, candidate API snapshots/diffs, behavior probes, current-state promotion manifests, and deterministic implementation gates for SDK update runs.
• Documentation for running the SDK evolution agent locally with supported vendor credentials and reviewing generated evidence.

Changed

• Updated resolver-selected lock entries for Claude and Antigravity after adapter-contract validation: claude-agent-sdk 0.2.106 and google-antigravity 0.1.4.
• Current-state manifests now record repo-relative checked-in artifact paths instead of machine-local absolute paths.

v0.1.1

Hardening release driven by a full-codebase review, with every adapter change verified against the real vendor SDKs.

Fixed

• Codex approval-mode mapping was inverted: STRICT/CAUTIOUS now map to deny_all (never escalate beyond the sandbox); DEFAULT/PERMISSIVE map to auto_review. Previously strict callers could have escalations auto-approved and permissive callers had them denied.
• Antigravity MCP stdio configuration no longer crashes (required name now passed).
• Codex honors TurnResult.status/error — failed and interrupted turns are no longer reported as success.
• Claude reports finish_reason="max_turns" on max-turns truncation.
• Strict mypy passes identically with and without vendor extras.

Changed (behavior)

• Antigravity DEFAULT posture is safer: nondestructive toolset instead of all tools + allow-all. STRICT/read-only → read-only toolset; PERMISSIVE keeps all tools.
• Previously silently-ignored task fields now raise UnsupportedTaskInputError (codex: tool filters/budget/network; antigravity: budget/network/allow+deny combo; claude: network).
• Antigravity session data moved from /tmp to $XDG_CACHE_HOME/agent-runtime-kit (0700), overridable via data_dir=.
• Missing SDKs/credentials raise typed AgentRuntimeUnavailableError.
• codex extra now requires openai-codex>=0.1.0b3 so it installs on glibc Linux.

Added

• Real incremental streaming events for Claude; tool audits for Codex parsed from TurnResult.items.
• Dropped vendor kwargs surfaced in AgentResult.metadata["dropped_options"].
• CI matrix (Python 3.10–3.13 × core/all-extras); publishing now gates on tests.
• Real-SDK contract tests; sdist allowlist (no internal artifacts shipped).

Full details in CHANGELOG.md.

v0.1.0

First release of agent-runtime-kit.

Highlights:

• Dependency-free core package with typed AgentTask, AgentResult, runtime protocol, registry, fake runtime, and availability diagnostics.
• Normalized task/output/tool/vendor event helpers with redaction and truncation defaults.
• Optional Claude, Codex, and Antigravity runtime adapters with lazy imports and explicit capability handling.
• Fake SDK harness and credential-free adapter tests.
• Same-task multi-runtime example, capability matrix, live smoke test guide, and Mestre migration notes.

Verification:

• uv run pytest: 22 passed, 3 live provider smokes skipped by design.
• uv run ruff check .: passed.
• uv run mypy: passed.
• uv run python -m build: wheel and sdist built.

PyPI publish notes:

• Package name: agent-runtime-kit.
• Version: 0.1.0.
• PyPI name check returned FREE immediately before this release, but recheck once more right before publishing.
