update the options test to provide and assert the cwd value.
In `@src/providers/claude-provider-rename-migration.ts`:
- Around line 58-61: Update projectClaudeProviderRename so it moves the
claude-cli row and changes its adapter only when the row’s adapter is
claude-cli. Leave rows with other adapters, such as anthropic, and their
references unchanged, and emit a warning for those rows; add a regression test
confirming an anthropic row keyed claude-cli remains untouched.
- Around line 45-57: Update the migration flow so `claude-cli` adapter values
are rewritten before either refusal branch returns the original configuration,
allowing refused configurations to resolve through the exact `PROVIDER_REGISTRY`
lookup. Add a regression test that builds an adapter from a refused
configuration.

…configs `claude-cli` shipped in 2.65.0 and named the transport the row used to be: a hand-built `claude -p` turn. The row is moving onto Anthropic's Claude Agent SDK — the harness behind the Claude Code CLI — and the old name also collided with `src/providers/claude-cli-identity.ts`, which forges a `claude-cli/<ver>` user agent for the Messages-API rows. The registry row, the adapter key and the adapter module are renamed. `claude-cli` keeps resolving through `DEPRECATED_PROVIDER_ALIASES`, and `claude-provider-rename-migration` moves the saved row, an explicit adapter string on a custom-named row, and every cross-config reference shape the shared rewriter owns; it refuses with a warning when the destination key is already taken or a keyed map collides, because two rows can describe two different sign-ins. The new projection runs first in the shared startup pass so later repairs see the canonical id. Docs, the structure map and the test layout follow the rename; `tests/claude-integration/` keeps its `claude-cli` file, which pins the CLI client path, not this provider.
The row spends a Claude subscription on a client that is not Claude Code, which is the traffic Anthropic suspended accounts over when it banned consumer OAuth in third-party apps. The registry comment and the user-visible `note` framed that as "Anthropic's call, flagged for maintainer review", which reads like a supported path with a footnote. Both now say what it is: against the terms, enforceable, and the loss lands on the signed-in account rather than on OpenCodex. The provider guide opens the section with the same warning instead of closing it with a remark, and the adapter doc names the two routes that do not depend on that reading — `anthropic-apikey` for automated clients, `ocx claude` where the genuine CLI is the client.
What we shipped in 2.65.0 was against Anthropic's terms: an OpenCodex-made one-shot `claude -p` turn with the caller's prompt replacing the harness prompt, no session and the harness tools stripped, driven by a client that is not Claude Code. A Claude subscription is licensed for Anthropic's own harnesses, and that construction spent it as an API behind a thin CLI veneer for a third-party agent loop, which is the usage accounts get suspended over. Meridian's route is safer because the harness runs the turn, and this row is the correction that takes it. That is not the same as clean, and the text now says so: the client is still not Claude Code, so the row stays a grey area, and `anthropic-apikey` is the only route without an interpretation question. The previous wording made who makes the request the criterion, which reads as an argument for a row that instead has to say what it was and what changed. The registry comment, the row's user-visible `note`, the provider guide (warning at the head of the section, terms remark at its end) and the structure map now carry the chain in plain language.
`src/providers/registry.ts` sits at a 232-line ratchet cap, and the renamed-id resolver the `claude-agent-sdk` row needs pushed it to 251 — `file-size ratchet: repository` fails for this branch and for every branch cut from `dev` afterwards. Caps only move down, so the remedy is a move: the alias table and `resolveDeprecatedProviderId` now live in `src/providers/deprecated-provider-aliases.ts`, which `getProviderRegistryEntry` imports. The comment above `mergeRegistryStaticHeaders` is re-wrapped onto one line less for the same reason, word for word otherwise. The table keeps its rationale: three paths read a retired id outside the rename projection (an early config read, `ocx provider test claude-cli` typed by hand, and a row the projection refused to move).
…luded The adapter no longer builds a `claude -p` command. It calls the Claude Agent SDK's `query()`, which is what this row was supposed to be from the start: the harness keeps its own preset with the caller's instructions APPENDED, the turn is the harness's session, and the client's tool catalog is served by an in-process MCP server (`type: "sdk"`) that advertises the request's own JSON Schema, captures calls and never answers one. Built-in tools stay off, no setting source is loaded, and `persistSession: false` keeps another client's conversation out of the operator's `~/.claude` transcripts. Nothing travels through argv any more — no staged prompt file, no `--mcp-config` path, no second executable. The ToS chain the docs state is now the code's shape, not an intention: the harness does the work instead of being driven by a foreign client, which is Meridian's route. It is still a grey area, and the registry comment, the row's `note`, the provider guide and the structure map say so. Dependency: `@anthropic-ai/claude-agent-sdk` plus its platform package — the Claude Code build it drives, ~230 MB unpacked, the same binary the `claude` npm package installs. Its peer dependencies (`@modelcontextprotocol/sdk`, `zod`) are already runtime dependencies here. Compiled binaries cannot resolve that package path from inside `$bunfs`, so they drive the `claude` on PATH instead and report `cli_not_found` when it is missing; the guide documents both paths. Flagged for security review in the PR description. Shared: `TOOL_BRIDGE_SYSTEM_PROMPT` moved to `coding-agent/tool-bridge-directive.ts` so CodeBuddy and this row cannot describe the bridge differently. The catalog validation, aliasing and name mapping are CodeBuddy's builder, reused on purpose. The bridge contract (init handshake before any call, exact catalog names, per-turn call cap, `tool_choice` and incomplete-call fail-closed) is enforced in both runners, deliberately parallel to `coding-agent/turn.ts`. Verification: `bun run typecheck` clean; 35 tests in `tests/providers/claude-agent-sdk-adapter.test.ts`; focused set 136 pass; `bun test tests/providers` compared against a pristine `origin/dev` control worktree — the same failures, none new; `structure:check`, `privacy:scan` and the file-size ratchet green.
The transport itself is unchanged; these are the defects the first review round found around it. - The retired adapter id keeps resolving. A refused projection (destination row taken, or a colliding keyed map) leaves a saved row saying adapter: "claude-cli", and the adapter it named no longer exists, so `getAdapterDefinition` now reads the same deprecation table the provider-id lookup uses instead of throwing "Unknown adapter". - Only the row the retired preset seeded is renamed. A row that carries the retired NAME on another adapter is the operator's own provider: the projection leaves it, its transport, its billing and every reference to it untouched, and says so in a warning. - The harness runs in an empty per-turn scratch directory instead of process.cwd(): the claude_code preset reports its working directory and a git-status summary to the model, which is the proxy's own tree rather than anything the client sent. The directory is removed once the harness is gone, and a directory that cannot be created fails the turn instead of falling back. - @anthropic-ai/claude-agent-sdk moves to optionalDependencies: it carries the Claude Code build it drives (~230 MB unpacked per platform), an install that omits optional dependencies should not have to carry it, and the missing package already has its own failure path (claude_agent_sdk_unavailable). Live against the signed-in subscription: text and tool turns still answer (3.5 s for the tool turn, zero orphan harness processes), the scratch directory is gone afterwards, and no lease on it survives the turn.

Summary
claude-cli(feat(provider): add a Claude Code CLI subscription provider #5712): an id that named the transport it used to be — a hand-builtclaude -pturn — and that collided withsrc/providers/claude-cli-identity.ts, the module which forges aclaude-cli/<ver>user agent for the Messages-API rows. The registry row is nowclaude-agent-sdk("Claude Agent SDK (subscription)"), and the adapter key and module follow. The retired id keeps resolving throughDEPRECATED_PROVIDER_ALIASES, andclaude-provider-rename-migrationmoves the saved row, an explicit adapter string on a custom-named row, and every cross-config reference shape the shared rewriter owns (routed strings, bare ids, keyed maps). It refuses with a warning when the destination row already exists or a keyed map collides, because two rows can describe two different sign-ins; the projection runs first in the shared startup pass so later repairs see the canonical id.claude -pcommand: it calls the Claude Agent SDK'squery(). The harness keeps its own system-prompt preset with the caller's instructions appended, the turn is the harness's session, built-in tools stay off (tools: []), no CLAUDE.md, skill, hook, plugin or MCP source from the machine is loaded (settingSources: [],strictMcpConfig: true), andpersistSession: falsekeeps another client's conversation out of the operator's~/.claudetranscripts. The request's tool catalog is served to the model by an in-process MCP server (type: "sdk") that advertises the request's own JSON Schema, captures calls and never answers one, so approval, sandboxing and execution stay with the client. Nothing travels through argv any more — no staged prompt file, no--mcp-configpath, no second executable.@anthropic-ai/claude-agent-sdkunderoptionalDependencies(a regular dependency until the review round) plus its platform package — the Claude Code build it drives (~230 MB unpacked per platform; the same binary theclaudenpm package installs). Its peer dependencies (@modelcontextprotocol/sdk,zod) are already runtime dependencies of this repository.MAINTAINERS.mdrequires explicit security review for dependency installation; this PR does not claim that review, andhygienereportsunsponsored_surfaceonpackage.jsonandbun.lockfor exactly this reason — the check clears with themaintainer-sponsoredlabel once a maintainer has completed that review, and until then the draft flag stays set by the gate: that review, and nothing else on this list, is what this PR is waiting for. A compiled single-file build cannot resolve a package path from inside$bunfs, so it drives theclaudeonPATHinstead and reportscli_not_foundwhen it is missing — both paths are documented in the provider guide.(
adapter: "claude-cli"on a row the projection refused) now resolves through the same deprecationtable as the provider id, instead of failing as an unknown adapter at request time; a row that carries
the retired NAME on another adapter - the operator's own provider - is left alone with its transport,
its billing and every reference to it, and a warning says so; the harness runs in an empty per-turn
scratch directory instead of
process.cwd(), so the preset's working-directory and git-statuscontext cannot describe the machine OpenCodex runs on, and the directory is removed once the harness
is gone; and the SDK is optional, so an install that omits optional dependencies does not carry its
~230 MB.
