- Adds a core-owned realtime backend prompt template and preparation
path.
- Makes omitted realtime start prompts use the core default, while null
or empty prompts intentionally send empty instructions.
- Covers the core realtime path and app-server v2 path with integration
coverage.

## Summary
- split `models-manager` out of `core` and add `ModelsManagerConfig`
plus `Config::to_models_manager_config()` so model metadata paths stop
depending on `core::Config`
- move login-owned/auth-owned code out of `core` into `codex-login`,
move model provider config into `codex-model-provider-info`, move API
bridge mapping into `codex-api`, move protocol-owned types/impls into
`codex-protocol`, and move response debug helpers into a dedicated
`response-debug-context` crate
- move feedback tag emission into `codex-feedback`, relocate tests to
the crates that now own the code, and keep broad temporary re-exports so
this PR avoids a giant import-only rewrite
## Major moves and decisions
- created `codex-models-manager` as the owner for model
cache/catalog/config/model info logic, including the new
`ModelsManagerConfig` struct
- created `codex-model-provider-info` as the owner for provider config
parsing/defaults and kept temporary `codex-login`/`codex-core`
re-exports for old import paths
- moved `api_bridge` error mapping + `CoreAuthProvider` into
`codex-api`, while `codex-login::api_bridge` temporarily re-exports
those symbols and keeps the `auth_provider_from_auth` wrapper
- moved `auth_env_telemetry` and `provider_auth` ownership to
`codex-login`
- moved `CodexErr` ownership to `codex-protocol::error`, plus
`StreamOutput`, `bytes_to_string_smart`, and network policy helpers to
protocol-owned modules
- created `codex-response-debug-context` for
`extract_response_debug_context`, `telemetry_transport_error_message`,
and related response-debug plumbing instead of leaving that behavior in
`core`
- moved `FeedbackRequestTags`, `emit_feedback_request_tags`, and
`emit_feedback_request_tags_with_auth_env` to `codex-feedback`
- deferred removal of temporary re-exports and the mechanical import
rewrites to a stacked follow-up PR so this PR stays reviewable
## Test moves
- moved auth refresh coverage from `core/tests/suite/auth_refresh.rs` to
`login/tests/suite/auth_refresh.rs`
- moved text encoding coverage from
`core/tests/suite/text_encoding_fix.rs` to
`protocol/src/exec_output_tests.rs`
- moved model info override coverage from
`core/tests/suite/model_info_overrides.rs` to
`models-manager/src/model_info_overrides_tests.rs`

- [x] Polish tool suggest prompts to distinguish between missing
connectors and discoverable plugins, and be very precise about the
triggering conditions.
- rename the multi-agent tool name the model sees to wait_agent
- update the model-facing prompts and tool descriptions to match

- [x] Add mentions of connectors because model always think in connector
terms in its CoT.
- [x] Suppress list_mcp_resources in favor of tool search for available
apps.
## Summary
- update `codex-rs/core/templates/memories/stage_one_system.md` so phase
1 captures stronger user-preference signals, richer task summaries, and
cwd provenance without branch-specific fields
- update `codex-rs/core/templates/memories/consolidation.md` so phase 2
keeps separate sections for user preferences, reusable knowledge, and
failure shields while staying cwd-aware but branchless
- document the `codex` prompt-template maintenance rule in
`codex-rs/core/src/memories/README.md`: the undated templates are
canonical here and should be edited in place
## Testing
- cargo test -p codex-core memories --manifest-path codex-rs/Cargo.toml
## Why
to support a new bring your own search tool in Responses
API(https://developers.openai.com/api/docs/guides/tools-tool-search#client-executed-tool-search)
we migrating our bm25 search tool to use official way to execute search
on client and communicate additional tools to the model.
## What
- replace the legacy `search_tool_bm25` flow with client-executed
`tool_search`
- add protocol, SSE, history, and normalization support for
`tool_search_call` and `tool_search_output`
- return namespaced Codex Apps search results and wire namespaced
follow-up tool calls back into MCP dispatch
## Why
- tighten Codex memory-read behavior around stale facts and conflicting
memory
- encode the risk-of-drift vs verification-effort decision rule directly
in the read-path prompt
- make partial stale-detail updates explicit so correcting only the
answer is not treated as sufficient
## What changed
- update `codex-rs/core/templates/memories/read_path.md`
- add guidance for when to verify cheap local facts vs when to answer
from older memory with visible provenance
- strengthen same-turn `MEMORY.md` updates when stored concrete details
are stale
## Notes
- this is based on some staleness eval work
## Summary
- allow `request_user_input` in Default collaboration mode as well as
Plan
- update the Default-mode instructions to prefer assumptions first and
use `request_user_input` only when a question is unavoidable
- update request_user_input and app-server tests to match the new
Default-mode behavior
- refactor collaboration-mode availability plumbing into
`CollaborationModesConfig` for future mode-related flags
## Codex author
`codex resume 019c9124-ed28-7c13-96c6-b916b1c97d49`
Add a stream parser to extract citations (and others) from a stream.
This support cases where markers are split in differen tokens.
Codex never manage to make this code work so everything was done
manually. Please review correctly and do not touch this part of the code
without a very clear understanding of it
## Summary
- tighten the memory-use decision boundary so agents skip memory only
for clearly self-contained asks
- make the quick memory pass more explicit and bounded (including a
lightweight search budget)
- add structured `<memory_citation>` requirements and examples for final
replies
- clarify memory update guidance and end-state wording for memory lookup
## Why
The previous template was directionally correct, but still left room for
inconsistent memory lookup behavior and citation formatting. This change
makes the default behavior, quick-pass scope, and citation output
contract much more explicit.
## Testing
- not run (prompt/template text change only)

## Summary
- Add `rollout_summary_file: <generated>.md` to each thread header in
`raw_memories.md` so Phase 2 can reliably reference the canonical
rollout summary filename.
- Update the memory prompts/templates (`stage_one_system`,
`consolidation`, `read_path`) for the new task-oriented raw-memory /
MEMORY.md schema and stronger consolidation guidance.
## Details
- `codex-rs/core/src/memories/storage.rs`
- Writes the generated `rollout_summary_file` path into the per-thread
metadata header when rebuilding `raw_memories.md`.
- `codex-rs/core/src/memories/tests.rs`
- Verifies the canonical `rollout_summary_file` header is present and
ordered after `updated_at`/`cwd` in `raw_memories.md`.
- Verifies task-structured raw-memory content is preserved while the
canonical header is added.
- `codex-rs/core/templates/memories/*.md`
- Updates the stage-1 raw-memory format to task-grouped sections
(`task`, `task_group`, `task_outcome`).
- Updates Phase 2 consolidation guidance around recency (`updated_at`),
task-oriented `MEMORY.md` blocks, and richer evidence-backed
consolidation.
- Tweaks the quick memory pass wording to emphasize topics/workflows in
addition to keywords.
## Testing
- `cargo test -p codex-core memories`
## Summary
- Require revised `<proposed_plan>` blocks in the same planning session
to be complete replacements, not partial/delta plans.
- Scope that cumulative replacement rule to the current planning session
only.
- Clarify that after leaving Plan mode (for example switching to Default
mode to implement) or when explicitly asked for a new plan, the model
should produce a new self-contained plan without inheriting prior plan
blocks unless requested.
## Testing
- Not run (prompt/template text-only change).
### What changed
1. Removed per-turn MCP selection reset in `core/src/tasks/mod.rs`.
2. Added `SessionState::set_mcp_tool_selection(Vec<String>)` in
`core/src/state/session.rs` for authoritative restore behavior (deduped,
order-preserving, empty clears).
3. Added rollout parsing in `core/src/codex.rs` to recover
`active_selected_tools` from prior `search_tool_bm25` outputs:
- tracks matching `call_id`s
- parses function output text JSON
- extracts `active_selected_tools`
- latest valid payload wins
- malformed/non-matching payloads are ignored
4. Applied restore logic to resumed and forked startup paths in
`core/src/codex.rs`.
5. Updated instruction text to session/thread scope in
`core/templates/search_tool/tool_description.md`.
6. Expanded tests in `core/tests/suite/search_tool.rs`, plus unit
coverage in:
- `core/src/codex.rs`
- `core/src/state/session.rs`
### Behavior after change
1. Search activates matched tools.
2. Additional searches union into active selection.
3. Selection survives new turns in the same thread.
4. Resume/fork restores selection from rollout history.
5. Separate threads do not inherit selection unless forked.
## Summary
- Created branch zuxin/read-path-update from main.
- Copied codex-rs/core/templates/memories/read_path.md from the current
branch.
- Committed the content change.
## Testing
Not run (content copy + commit only).
## Summary
- Limit `search_tool_bm25` indexing to `codex_apps` tools only, so
non-Apps MCP servers are no longer discoverable through this search
path.
- Move search-tool discovery guidance into the `search_tool_bm25` tool
description (via template include) instead of injecting it as a separate
developer message.
- Update Apps discovery guidance wording to clarify when to use
`search_tool_bm25` for Apps-backed systems (for example Slack, Google
Drive, Jira, Notion) and when to call tools directly.
- Remove dead `core` helper code (`filter_codex_apps_mcp_tools` and
`codex_apps_connector_id`) that is no longer used after the
tool-selection refactor.
- Update `core` search-tool tests to assert codex-apps-only behavior and
to validate guidance from the tool description.
## Validation
- ✅ `just fmt`
- ✅ `cargo test -p codex-core search_tool`
- ⚠️ `cargo test -p codex-core` was attempted, but the run repeatedly
stalled on
`tools::js_repl::tests::js_repl_can_attach_image_via_view_image_tool`.
