The current bug template uses CLI-specific instructions for getting the
version.
The current feature template doesn't ask the user to provide the Codex
variant (surface) they are using.
This PR addresses these problems.
Two fixes:
1. Include trailing tool output in the total context size calculation.
Otherwise when checking whether compaction should run we ignore newly
added outputs.
2. Trim trailing tool output/tool calls until we can fit the request
into the model context size. Otherwise the compaction endpoint will fail
to compact. We only trim items that can be reproduced again by the model
(tool calls, tool call outputs).
###### Summary
- Add input_modalities to model metadata so clients can determine
supported input types.
- Gate image paste/attach in TUI when the selected model does not
support images.
- Block submits that include images for unsupported models and show a
clear warning.
- Propagate modality metadata through app-server protocol/model-list
responses.
- Update related tests/fixtures.
###### Rationale
- Models support different input modalities.
- Clients need an explicit capability signal to prevent unsupported
requests.
- Backward-compatible defaults preserve existing behavior when modality
metadata is absent.
###### Scope
- codex-rs/protocol, codex-rs/core, codex-rs/tui
- codex-rs/app-server-protocol, codex-rs/app-server
- Generated app-server types / schema fixtures
###### Trade-offs
- Default behavior assumes text + image when field is absent for
compatibility.
- Server-side validation remains the source of truth.
###### Follow-up
- Non-TUI clients should consume input_modalities to disable unsupported
attachments.
- Model catalogs should explicitly set input_modalities for text-only
models.
###### Testing
- cargo fmt --all
- cargo test -p codex-tui
- env -u GITHUB_APP_KEY cargo test -p codex-core --lib
- just write-app-server-schema
- cargo run -p codex-cli --bin codex -- app-server generate-ts --out
app-server-types
- test against local backend

This PR addresses #10395
When a user is asked to pick the trust level of a project, the code
currently reloads the config if they select "trusted". It doesn't reload
the config in the "untrusted" case but should. This causes the sandbox
mode to be reported incorrectly in `/status` during the first run (it's
displayed as `read-only` even though it acts as though it's
`workspace-write`).
We started working with MCP in Codex before
https://crates.io/crates/rmcp was mature, so we had our own crate for
MCP types that was generated from the MCP schema:
8b95d3e082/codex-rs/mcp-types/README.md
Now that `rmcp` is more mature, it makes more sense to use their MCP
types in Rust, as they handle details (like the `_meta` field) that our
custom version ignored. Though one advantage that our custom types had
is that our generated types implemented `JsonSchema` and `ts_rs::TS`,
whereas the types in `rmcp` do not. As such, part of the work of this PR
is leveraging the adapters between `rmcp` types and the serializable
types that are API for us (app server and MCP) introduced in #10356.
Note this PR results in a number of changes to
`codex-rs/app-server-protocol/schema`, which merit special attention
during review. We must ensure that these changes are still
backwards-compatible, which is possible because we have:
```diff
- export type CallToolResult = { content: Array<ContentBlock>, isError?: boolean, structuredContent?: JsonValue, };
+ export type CallToolResult = { content: Array<JsonValue>, structuredContent?: JsonValue, isError?: boolean, _meta?: JsonValue, };
```
so `ContentBlock` has been replaced with the more general `JsonValue`.
Note that `ContentBlock` was defined as:
```typescript
export type ContentBlock = TextContent | ImageContent | AudioContent | ResourceLink | EmbeddedResource;
```
so the deletion of those individual variants should not be a cause of
great concern.
Similarly, we have the following change in
`codex-rs/app-server-protocol/schema/typescript/Tool.ts`:
```
- export type Tool = { annotations?: ToolAnnotations, description?: string, inputSchema: ToolInputSchema, name: string, outputSchema?: ToolOutputSchema, title?: string, };
+ export type Tool = { name: string, title?: string, description?: string, inputSchema: JsonValue, outputSchema?: JsonValue, annotations?: JsonValue, icons?: Array<JsonValue>, _meta?: JsonValue, };
```
so:
- `annotations?: ToolAnnotations` ➡️ `JsonValue`
- `inputSchema: ToolInputSchema` ➡️ `JsonValue`
- `outputSchema?: ToolOutputSchema` ➡️ `JsonValue`
and two new fields: `icons?: Array<JsonValue>, _meta?: JsonValue`

## Summary
This PR improves the TUI experience for `request_user_input` by
rendering submitted question/answer sets directly in conversation
history with clear, structured formatting.
It also intentionally simplifies interrupt behavior for now: on `Esc` /
`Ctrl+C`, the questions overlay interrupts the turn without attempting
to submit partial answers.

/>
## Scope
- TUI-only changes.
- No core/protocol/app-server behavior changes in this PR.
- Resume reconstruction of interrupted question sets is out of scope for
this PR.
## What Changed
- Added a new history cell: `RequestUserInputResultCell` in
`codex-rs/tui/src/history_cell.rs`.
- On normal `request_user_input` submission, TUI now inserts that
history cell immediately after sending `Op::UserInputAnswer`.
- Rendering includes a `Questions` header with `answered/total` count.
- Rendering shows each question as a bullet item.
- Rendering styles submitted answer lines in cyan.
- Rendering styles notes (for option questions) as `note:` lines in
cyan.
- Rendering styles freeform text (for no-option questions) as `answer:`
lines in cyan.
- Rendering dims only the `(unanswered)` suffix.
- Rendering can include an interrupted suffix and summary text when the
cell is marked interrupted.
- Rendering redacts secret questions as `••••••` instead of showing raw
values.
- Added `wrap_with_prefix(...)` in `history_cell.rs` for wrapped
prefixed lines.
- Added `split_request_user_input_answer(...)` in `history_cell.rs` for
decoding `"user_note: ..."` entries.
## Interrupt Behavior (Intentional for this PR)
- `Esc` / `Ctrl+C` in the questions overlay now performs `Op::Interrupt`
and exits the overlay.
- It does **not** submit partial/committed answers on interrupt.
- Added TODO comments in `request_user_input` overlay interrupt paths
indicating where interrupted partial result emission should be
reintroduced once core support is finalized.
- Queued `request_user_input` overlays are discarded on interrupt in the
current behavior.
## Tests Updated
- Updated/added overlay tests in
`codex-rs/tui/src/bottom_pane/request_user_input/mod.rs` to reflect
interrupt-only behavior.
- Added helper assertion for interrupt-only event expectation.
- Existing submission-path tests now validate history insertion behavior
and expected answer maps.
## Behavior Notes
- Completed question flows now produce a readable `Questions` block in
transcript history.
- Interrupted flows currently do not persist partial answers to
model-visible tool output.
## Follow-ups
- Reintroduce partial-answer-on-interrupt semantics once core can
persist/sequence interrupted `request_user_input` outputs safely.
- Optionally add replay/resume rendering for interrupted question sets
as a separate PR.
