Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[0.9.2] - 2026-09-29

Changed

• Refresh the authenticated Codex CLI catalog: GPT-6.1 Sol is the default at low effort; align current picker efforts, defaults, descriptions, and GPT-5.5 upgrade metadata.

0.9.1 - 2026-09-26

Fixed

• Deliver large Codex exec prompts through bootstrap stdin instead of argv. This avoids the erlexec port command size failure while preserving the existing prompt and EOF behavior.

0.9.0 - 2026-09-26

Changed

• Refresh the Codex picker catalog with GPT-6 Sol and GPT-6 Luna, keeping GPT-6 Astra as default and moving GPT-5.4 Mini out of the visible picker.
• Record the supported reasoning efforts and default medium effort for Sol and Luna.

0.8.0 - 2026-09-17

• Preserve explicit claude-fable-5 and claude-fable-5-1 model IDs instead of collapsing them into the provider-dependent fable alias.

Added

• Add Gemini models to the Antigravity provider model catalog (priv/models/antigravity.json), including gemini-3.8-flash (with reasoning effort scaling for low, medium, and high), gemini-3.7-flash, gemini-3.6-flash, and gemini-3.1-pro.
• Forward --model and --effort CLI flags in CliSubprocessCore.ProviderProfiles.Antigravity when non-default models or reasoning efforts are resolved in the model payload.
• Update Claude model catalog (priv/models/claude.json) to 2026-09-17, adding pinned claude-fable-5-1 and fable-5.1 shorthand for Claude Fable 5.1 with 75% discounted cache read pricing ($0.25/Mtok), and adding mythos-5.1 (Claude Mythos 5.1) under restricted visibility.
• Update Codex model catalog (priv/models/codex.json) to 2026-09-03, adding gpt-6-astra (GPT-6-Astra) frontier reasoning and agentic coding model with multi-tier reasoning efforts (low, medium, high, xhigh, max).
• Synchronize the Codex picker with authenticated CLI 0.153.4: Astra is the default at low effort, including CLI-only ultra; hide reserve/review entries and remove retired picker entries. API effort support remains separately documented.
• Render the restricted Mythos model using its full provider identifier, claude-mythos-5-1.
• Require execution_plane_process 0.3.1 with the erlexec EOF-loop fix.

0.7.0 - 2026-08-10

Fixed

• Require execution_plane_process ~> 0.3.0, the first process-lane release with strict transient systemd-user containment.
• Classify exhausted provider credits and quota as the terminal provider_quota_exhausted recovery class, even when a CLI labels the error unknown. These failures cannot be repaired by another prompt or by an immediate retry; ordinary rate_limit errors remain bounded and retryable.
• Make the first-party model catalogs available from installed escripts. ModelCatalog previously read only Application.app_dir/2 paths. Inside an escript that path traverses the archive as though it were a directory, so every provider failed before launch with {:not_found, :enotdir}. Catalog JSON is now tracked and embedded at compile time, with filesystem-first loading and an embedded fallback. A regression test exercises the exact file-as-parent :enotdir shape while retaining the fail-closed error for an unknown provider.

0.6.0 - 2026-08-10

Added

• CliSubprocessCore.ProviderProfile.accepts_input_after_start?/1: whether a lane can actually be handed more input once its run has started. The answer requires an open stdin and an explicit :incremental_input capability; no shipped profile currently declares it, so current lanes interrupt and resume instead. capabilities/0 alone cannot distinguish the mechanisms.

Changed

• The two governed-binding validators in RuntimeGateway.Local and RuntimeGateway.RuntimeClient are ordered rule lists rather than duplicated cond chains. Same comparisons, same reason codes, same short-circuit: one row per ref, so adding a ref means adding a row.

Fixed

• Require execution_plane_jsonrpc ~> 0.2.0, the first JSON-RPC component release compatible with the core-only execution_plane ~> 0.3.0 line.

• ProviderProfile.accepts_input_after_start?/1 no longer reports claude as accepting live input. It derived the answer from close_stdin_on_start? alone, and an open file descriptor is not a reader: claude --print takes its prompt on argv, consumes stdin once while assembling it, and never reads it again. A caller acting on that answer had its message silently swallowed while every layer above reported success. The answer now requires both an open stdin and a profile declaring :incremental_input. No shipped profile declares it, so every lane is steered by interrupt and resume. Verified against the shipping CLI: text piped before the turn changes the answer, the same text written eight seconds in does not.

• The Claude profile decodes tool calls. claude --output-format stream-json does not emit top-level tool_use or tool_result events — it emits Anthropic messages, with a tool_use block inside an assistant message's content and its result inside the next user message. The profile handled only the top-level shapes, which the shipping CLI never produces, and had no handler for user at all. A Claude run that edited a dozen files therefore decoded as a dozen assistant messages with empty content, reported zero tools, and dropped every tool result as an unrecognized raw event.

  An assistant message now emits one event per content block, in block order: tool_use blocks become :tool_use, thinking blocks become :thinking, and text blocks become :assistant_message. A user message emits :tool_result per tool_result block, keyed by tool_use_id, with content blocks flattened to text. The top-level handlers are kept for older builds and hand-written fixtures.

  Consumers should expect :thinking events from Claude where none arrived before: they were previously swallowed inside the assistant message, not absent.

0.5.1 - 2026-08-10

Fixed

• Make the published package loadable by any consumer. mix.exs required build_support/dependency_sources.exs, which the package does not ship, so mix compile in a consuming project died while Mix loaded this dependency's project. It now detects a source checkout by that file's presence: in a checkout the registry resolves siblings path-first as before, and in a published package the Hex requirements stated in mix.exs are the whole answer. 0.5.0 is retired.

0.5.0 - 2026-08-10

Two provider profiles were written against event schemas their CLIs do not produce. Neither failed loudly; both simply reported that nothing happened.

Changed

• The Antigravity profile now requests --output-format stream-json. It previously ran agy --print, whose plain-text output was normalized one line at a time into assistant deltas — so a run produced text and nothing else: no tool calls, no token usage, no terminal result. agy reports a run as numbered steps that go ACTIVE then DONE, which supplies both halves of a tool call. A stdout line that is not JSON is still emitted as an assistant delta, so output_format: "text" and older CLIs keep working.
• Codex and Antigravity tool names and parameter keys are translated to the spellings consumers already use for other providers: a shell command is Bash carrying a command, a file edit is Edit carrying a file_path. Renderers and tool allowlists both key off these names, so a provider-specific spelling renders correctly while silently matching no allowlist entry.

Added

• The Codex profile decodes the item types codex exec --json actually emits: command_execution, file_change, mcp_tool_call, web_search and todo_list. It previously looked for item types named tool_call and tool_result, which the CLI has never emitted, so every tool call fell through to :raw and no consumer could see that the model had done anything. The older names are still accepted.
• item.started is decoded as tool_use, giving a live signal that a tool has begun rather than only that it finished. Both halves carry the item's id, which is what pairs a call with its result.

Fixed

• turn.failed is decoded, emitting both an error and a terminal result. It was previously unmapped, so a failed Codex turn produced no stop reason at all and a consumer waiting on one waited indefinitely.
• normalize_session_id/1 treated nil as an atom — which it is — and returned the string "nil". That value then overwrote the real provider session id on every event that did not carry one, so only the first event of a run held it. Every resume path reads that id back, and would have resumed a thread named "nil".
• The local runtime gateway derived an error's ambiguous flag by comparing its category against :ambiguous, a value that category can never hold — the gateway resolves every outcome it reports. Error.new/1 enforces ambiguous == (category == "ambiguous"), so the flag is now stated directly.

Removed

• Unreachable clauses in the runtime gateways, each proved dead by the type rather than by inspection: the clear_env? guard in both Local and RuntimeClient session-binding validation, since GovernedAuthority types that field as the literal true and enforces it in validate_clear_env/1; a non-map head of metadata_value/2 whose argument comes from a map-typed %Options{} field; and a third normalize_runtime_reply/1 head for a reply shape the runtime does not produce.

The package is Dialyzer- and Credo-clean with no ignore entries.

0.4.1 - 2026-07-27

Fixed

• The Claude profile now emits --effort from the shared model registry's normalized model_payload.reasoning. Previously Claude effort was validated and preserved in the payload, then silently dropped by the direct CLI lane.

0.4.0 - 2026-07-27

Added

• Total :structured_output and :completion_only feature manifests for all built-in providers plus ProviderFeatures.Error, whose provider, feature, option, and support state are pattern-matchable.
• CliSubprocessCore.EphemeralFile, a provider-neutral exclusive 0600 temporary-file primitive with owner monitoring and idempotent bounded teardown.
• Dependency-source helper v6 release edges from antigravity_cli_sdk and amp_sdk to cli_subprocess_core.

Changed

• Amp and Antigravity now reject unsupported schema and completion-only intent before resolving or starting their CLIs. Ordinary invocations are unchanged.
• OutputSchemaFile delegates secure materialization to the generic primitive while preserving its JSON validation and public error contract.
• Amp result projection preserves provider result text, status/subtype, durations, turns, usage totals, cost, and permission denials. Antigravity keeps non-empty provider output byte-faithful.

Fixed

• Removed redundant clauses diagnosed by Elixir 1.20 so the warnings-as-errors build remains green on the current release toolchain.
• Keep the opaque transport-error matcher dynamically callable after a downstream function has excluded generic exceptions. This prevents Elixir 1.20 from over-refining valid facade calls to an always-false branch while preserving the lower transport struct boundary.

0.3.0 - 2026-07-27

Added

• Payload.Result.object carries a provider-returned structured object. The Claude profile lifts structured_output off the result frame; the Codex profile decodes the schema-constrained final agent message, and only when the run actually requested a schema. A reply that is not JSON leaves the field nil rather than manufacturing an object. Amp, Cursor, and the synthetic exit result declare the field explicitly empty because no structured-output surface is proven for them.
• CliSubprocessCore.OutputSchemaFile and CliSubprocessCore.EphemeralFiles: an owner-monitored lifecycle for temporary files an invocation needs on disk. ProviderProfile.build_invocation/1 may now return {:ok, invocation, teardown}; Command.run/1 and Session run that teardown on a normal result, an error, an interrupt, and a close, while EphemeralFiles removes the file when the owning process is killed untrappably and never gets to run it.
• A completion-only invocation profile (completion_only: true). Claude receives an empty tool set, plan permission mode, no settings sources, and strict MCP config. Codex receives a read-only sandbox, ephemeral operation, no user config or rules, disabled web search and skills, and an approval_policy="never" config override. Both replace, rather than merge with, caller-supplied permission state.

Fixed

• Publish preflight now requires the exact sibling version developed against to exist on Hex. An older package release can no longer mask a missing current release, as the historical execution_plane 0.1.0 monolith did for the core-only execution_plane 0.2.0. Nested package tasks resolve the helper-owning repository, and a manifest self-entry is not treated as a circular prerequisite.
• --output-schema now receives a file path. codex exec types the flag as a path and exits non-zero when it cannot read the file, so the previous inline JSON encoding was a hard failure rather than a degraded mode.
• transport_headless_timeout_ms reaches the transport. Without the alias the declared orphan-reap window was silently replaced by the transport's own 30 s default, letting a subprocess outlive its owner by 25 s longer than the contract allows.
• Output-schema files use an OS-process-qualified, exclusive 0600 namespace, reject cross-owner tracking collisions, and are proven to disappear through every public command/session terminal path.

Changed

• Require the core-only execution_plane ~> 0.2.0; the historical 0.1.0 Hex package bundled the same process and JSON-RPC modules now supplied by the canonical component dependencies.
• Refreshed the zoi lock from 0.18.5 to 0.18.7.
• The shared Claude catalog advertises Opus 5. Both opus and the retained compatibility choice opus[1m] list claude-opus-5; Opus 5 is itself a 1M-context model, so no suffixed provider id is invented. Prior full ids (claude-opus-4-8, claude-opus-4-7) remain resolvable, matching how the Sonnet entry retains claude-sonnet-4-6.

0.2.0 - 2026-07-13

Added

• Current Codex GPT-5.6 Sol, Terra, and Luna catalog entries plus the public GPT-5.3-Codex-Spark ChatGPT Pro preview, including model-specific reasoning defaults and max/ultra validation.
• Cursor Agent CLI (:cursor) first-party provider profile with stream-json parsing, live fixture evidence, model catalog entries, and provider feature metadata.
• Documentation updates for Cursor as the fifth built-in profile, including invocation shape, permission metadata, governed posture, and capability hints.
• Atom-safety guardrail: .credo.exs with Credo.Check.Warning.UnsafeToAtom enabled (scoped to lib/) plus a scripts/atom_guard.sh CI backstop wired into mix ci (which now runs credo --strict).
• Secrets guardrail: scripts/secrets_guard.sh in mix ci; .env files gitignored.
• README documents registry ownership and hex publish-ordering: this package publishes first, then claude_agent_sdk / agent_session_manager.

Changed

• Restricted the Hex archive to runtime source, model data, dependency-source support, consumer guides/examples, and public release documentation/assets.
• Replaced separate Execution Plane core, JSON-RPC, and process package dependencies with the single generated execution_plane ~> 0.1.0 package.
• Local development now consumes the generated monolith artifact and clean clones fall back to the durable projection/execution_plane branch.
• The Codex catalog now follows an authenticated live codex-cli 0.144.1 model/list probe from 2026-07-10: gpt-5.6-sol is the default, Spark is public but non-API, codex-auto-review remains internal, and backend-absent gpt-5.2 stays excluded.
• Refreshed compatible dependencies, including Zoi 0.18.5.

Security

• Command env validation returns offending keys (or :not_a_map) in {:invalid_env, ...} error tuples instead of echoing the full env map, whose values routinely include credentials.

Removed

• Retired the Gemini CLI profile, catalog, discovery/fallback path, feature manifest, and model-selection workflow target. Google coding-agent support now uses the Antigravity profile only.

0.1.0 - 2026-04-06

Added

• Initial release.
• Governed CLI launch authority for command, cwd, env, config-root, auth-root, base-URL, target, and clear-env materialization without ambient provider CLI env discovery.
