Unreleased

0.3.0.3 — 2026-08-29

Changed

• Every library dependency now carries a PVP upper bound: aeson, bytestring, containers, directory, effectful, filepath, generic-lens, http-client, http-client-tls, http-types, process, regex-tdfa, vector. cabal check reported these under missing-upper-bounds. Without one, a future breaking release of a dependency enters a consumer's build plan unchecked — which is the failure the bound exists to prevent.

  Each bound admits the version this package is built and tested against and stops below the next major.

  aeson stops at <2.3 rather than <2.4: baikai-openai 0.5 constrains it to ^>=2.2, so aeson 2.3 is not reachable for this cohort and a wider bound would assert compatibility that cannot be exercised here.

  http-client-tls stops at <0.4 for the same reason — baikai-openai 0.5 constrains it to ^>=0.3.

0.3.0.2 — 2026-08-07

Changed

• Upgraded the baikai dependency to the 0.5 series (>=0.5 && <0.6). Dependency bounds only — no changes to the exported API.

0.3.0.1 - 2026-07-20

Changed

• Upgraded the baikai dependency to the 0.4 series (>=0.4 && <0.5). Dependency bounds only — no changes to the exported API.

0.3.0.0 - 2026-07-05

Added

• ReAct exposes Proposal, renderStepLine, and summaryStep; native ReAct turns can dispatch multiple tool calls in order before the next model turn.
• CodeActConfig now includes trajectory compaction settings, matching the ReAct context-window recovery path.
• Tooling exposes infrastructure-error classification, fetch-policy controls, capped HTTP response reading, and symlink information in directory listings.

Changed

• BREAKING ProtocolImpl.parsePropose now returns Proposal instead of Action, and trajectories can contain the new Summarized action injected by compaction.
• BREAKING CodeActConfig record construction requires the new compaction field.
• Tool bodies now rethrow budget and context-window exhaustion instead of feeding them back to the model as recoverable observations.
• Built-in filesystem, shell, and web tools are hardened: execution timeouts are clamped, default fetch policy rejects common local/private targets, and fetches cap bytes while streaming.
• Refreshed the internal shikumi bound for the 0.3 series.

0.2.0.0 - 2026-06-28

Added

• Built-in filesystem, shell, and web tool modules, plus helpers for assembling built-in tool registries.
• Shikumi.Tool.Env, an execution-environment record for filesystem and process backed tools.
• Shikumi.Tool.Web, a swappable HTTP/search client layer for web tools.

Changed

• ReActConfig now includes a compaction field, and ReAct agents compact older trajectory steps when usage approaches the model context window.
• Refreshed the internal shikumi bound for the 0.2 series.

0.1.0.1 - 2026-06-21

Changed

• Constrained the baikai dependency to the 0.2 series and refreshed internal shikumi bounds.

0.1.0.0 - 2026-06-13

Added

• Initial Hackage release of typed tool registries and ReAct-style agents for shikumi programs.
• CodeAct, program-of-thought helpers, prompt utilities, and a restricted deterministic code interpreter for offline tests.
