[dependabot]

Bumps band-sdk from 1.4.2 to 3.0.0.

Release notes

Sourced from band-sdk's releases.

band-sdk: v3.0.0

3.0.0 (2026-08-26)

⚠ BREAKING CHANGES

• AgentTools.get_tool_schemas/get_anthropic_tool_schemas/ get_openai_tool_schemas, iter_tool_definitions, and the MCP engine's registration builders replace their separate include_memory/include_contacts booleans with a single capabilities: frozenset[Capability] | None parameter.

Features

• add agent-scoped memory support (#575) (1227061)
• add file transfer capability to the Python SDK (INT-1261) (#573) (eb2a404)

Bug Fixes

• bound e2e health-check curls with --max-time (#570) (df379a6)
• flush the ACP collecting client at turn end in codex-acp e2e tests (#571) (e005fab)
• integrate band-sdk-core event validation into band-sdk-python (#574) (9bad9e5)
• stabilize Codex thought smoke (#567) (fc62742)

band-sdk: v2.1.0

2.1.0 (2026-08-23)

Features

• consolidate band-mcp into one SDK-owned MCP engine (INT-1096) (#552) (649f271)

band-sdk: v2.0.0

2.0.0 (2026-08-23)

⚠ BREAKING CHANGES

• ParlantAdapter(server=, parlant_agent=) is no longer required (both are now optional, keyword-only escape hatches), and the dead additional_tools parameter is removed — it was stored but never bridged into Parlant tool-calling (INT-1167 tracks the real bridge).

Features

• cohesive adapter construction surface (INT-1166) (#520) (1ca53ba)
• nightly baseline E2E schedule + release-please gate (#532) (56f8652)
• sdk: Claude Desktop Band agent integration (#501) (adc93d3)

Bug Fixes

• ask the rehydration smoke's retrieval turn to actually reply (#553) (b3aaa95)
• bring Copilot CLI (ACP) to the L4 bar (#543) (be68fa0)
• bump agent-client-protocol and bind ACP handlers by name (#542) (b4df94d)
• bump band-client-rest to 0.0.26, drop resolve_handle workaround (#531) (091a942)
• ci: forward Docker Hub secrets to kit publisher (#519) (8ecbb71)

✅ Approved by the dependabot-triage skill.

Validated in a consolidated batch run alongside #529 (pydantic-settings). uv sync resolves the echo-agent starter's own lock, main.py imports and constructs EchoAdapter cleanly against the new band-sdk major, and tests/docker/test_echo_agent.py still passes. No automated harness in this repo builds/runs this starter workspace's own lock inside a container end-to-end (the docker_build live test builds the base image from the root project's lock, not this one), so this was verified by direct import/construction rather than a live agent turn.

⚠️ This is a MAJOR version bump (1.4.2 → 3.0.0) of this repo's own SDK inside its example starter kit — flagging for human sign-off per the triage skill's guardrail on majors, even though it's green.
