Deprecate TurnContext cwd and resolve_path (#22519)
## Why `TurnContext::cwd` and `TurnContext::resolve_path` are being phased out in favor of using the selected turn environment cwd directly. Deprecating both APIs makes any new direct dependency visible while preserving the existing migration path for current callers. ## What Changed - Marked `TurnContext::cwd` and `TurnContext::resolve_path` as deprecated with guidance to use the selected turn environment cwd instead. - Added exact `#[allow(deprecated)]` suppressions at each existing direct usage site, including tests, rather than adding crate-wide suppression. - Kept the change behavior-preserving: current cwd reads, writes, and path resolution continue to use the same values. ## Verification - `just fmt` - `cargo check -p codex-core` - `cargo check -p codex-core --tests` - `git diff --check`

hooks: use new session IDs instead of thread IDs for hooks, apply parent's session ID to subagents' hooks (#22268)
## Why hook semantics treat `session_id` as shared across a root session and its subagents. Codex hooks were still emitting the current thread ID, which made spawned agents look like independent sessions and made it harder for hook integrations to correlate work across a root thread and its spawned helpers This change makes hooks use Codex's existing shared session identity so hook `session_id` matches the root-thread session across spawned subagents. ## What Changed - switch hook payloads to use the existing shared session identity from core instead of the current thread ID - cover all hook surfaces that expose `session_id`, including `SessionStart`, tool hooks, compact hooks, prompt-submit hooks, stop hooks, and legacy after-agent dispatch

Support PreToolUse updatedInput rewrites (#20527)
## Why `PreToolUse` already exposes `updatedInput` in its hook output schema, but Codex currently rejects it instead of applying the rewrite. That leaves hook authors unable to make the documented pre-execution adjustment to a tool call before it runs. ## What - Accept `updatedInput` from `PreToolUse` hooks when paired with `permissionDecision: "allow"`. - Apply the rewritten input before dispatch so the tool executes the updated payload, not the original one. - Preserve the stable hook-facing compatibility shapes that participating tool handlers expose: - Bash-like tools (`shell`, `container.exec`, `local_shell`, `shell_command`, `exec_command`) use `{ "command": ... }`. - `apply_patch` exposes its patch body through the same command-shaped hook contract. - MCP tools expose their JSON argument object directly. - Keep each participating tool handler responsible for translating hook-facing `updatedInput` back into its concrete invocation shape. ## Verification Direct Bash-like rewrite coverage: - `pre_tool_use_rewrites_shell_before_execution` - `pre_tool_use_rewrites_container_exec_before_execution` - `pre_tool_use_rewrites_local_shell_before_execution` - `pre_tool_use_rewrites_shell_command_before_execution` - `pre_tool_use_rewrites_exec_command_before_execution` These cases assert that each supported Bash-like surface runs only the rewritten command while the hook still observes the original `{ "command": ... }` input. `pre_tool_use_rewrites_apply_patch_before_execution` - Model emits one patch. - Hook swaps in a different patch. - Asserts only the rewritten file is created, and the hook saw the original patch. `pre_tool_use_rewrites_code_mode_nested_exec_command_before_execution` - Model runs one nested shell command from code mode. - Hook rewrites it. - Asserts only the rewritten command runs, and the hook saw the original nested input. `pre_tool_use_rewrites_mcp_tool_before_execution` - Model calls the RMCP echo tool. - Hook rewrites the MCP arguments. - Asserts the MCP server receives and returns the rewritten message, not the original one.Abhinav ·

Add compact lifecycle hooks (started by vincentkoc - external contrib) (#19905)
Based on work from Vincent K - https://github.com/openai/codex/pull/19060 <img width="1836" height="642" alt="CleanShot 2026-04-29 at 20 47 40@2x" src="https://github.com/user-attachments/assets/b647bb89-65fe-40c8-80b0-7a6b7c984634" /> ## Why Compaction rewrites the conversation context that future model turns receive, but hooks currently have no deterministic lifecycle point around that rewrite. This adds compact lifecycle hooks so users can audit manual and automatic compaction, surface hook messages in the UI, and run post-compaction follow-up without overloading tool or prompt hooks. ## What Changed - Added `PreCompact` and `PostCompact` hook events across hook config, discovery, dispatch, generated schemas, app-server notifications, analytics, and TUI hook rendering. - Added trigger matching for compact hooks with the documented `manual` and `auto` matcher values. - Wired `PreCompact` before both local and remote compaction, and `PostCompact` after successful local or remote compaction. - Kept compact hook command input to lifecycle metadata: session id, Codex turn id, transcript path, cwd, hook event name, model, and trigger. - Made compact stdout handling consistent with other hooks: plain stdout is ignored as debug output, while malformed JSON-looking stdout is reported as failed hook output. - Added integration coverage for compact hook dispatch, trigger matching, post-compact execution, and the audited behavior that `decision:"block"` does not block compaction. ## Out of Scope - Hook-specific compaction blocking is not implemented; `decision:"block"` and exit-code-2 blocking semantics are intentionally unsupported for `PreCompact`. - Custom compaction instructions are not exposed to compact hooks in this PR. - Compact summaries, summary character counts, and summary previews are not exposed to compact hooks in this PR. ## Verification - `cargo test -p codex-hooks` - `cargo test -p codex-core manual_pre_compact_block_decision_does_not_block_compaction` - `cargo test -p codex-app-server hooks_list` - `cargo test -p codex-core config_schema_matches_fixture` - `cargo test -p codex-tui hooks_browser` ## Docs The developer documentation for Codex hooks should be updated alongside this feature to document `PreCompact` and `PostCompact`, the `manual`/`auto` matcher values, and the compact hook payload fields. --------- Co-authored-by: Vincent Koc <vincentkoc@ieee.org>

Support PreToolUse additionalContext (#20692)
# Why `PreToolUse` already exposes `hookSpecificOutput.additionalContext` in the generated hook schema, but the runtime still rejected it as unsupported. That leaves `PreToolUse` out of step with the other context-injecting hooks and prevents hook authors from attaching model-visible guidance to a pending tool call before it runs. # What - Parse `PreToolUse.additionalContext` and carry it through the hook event pipeline. - Record `PreToolUse` context at the hook boundary so successful context is preserved for both allowed and blocked calls without widening the tool registry surface. - Preserve existing deny behavior when context is combined with either `permissionDecision: "deny"` or the legacy `decision: "block"` shape.

Add persisted hook enablement state (#19840)
## Why After `hooks/list` exposes the hook inventory, clients need a way to persist user hook preferences, make those changes effective in already-open sessions, and distinguish user-controllable hooks from managed requirements without adding another bespoke app-server write API. ## What - Extends `hooks/list` entries with effective `enabled` state. - Persists user-level hook state under `hooks.state.<hook-id>` so the model can grow beyond a single boolean over time. - Uses the existing `config/batchWrite` path for hook state updates instead of introducing a dedicated hook write RPC. - Refreshes live session hook engines after config writes so already-open threads observe updated enablement without a restart. ## Stack 1. openai/codex#19705 2. openai/codex#19778 3. This PR - openai/codex#19840 4. openai/codex#19882 ## Reviewer Notes The generated schema files account for much of the raw diff. The core behavior is in: - `hooks/src/config_rules.rs`, which resolves per-hook user state from the config layer stack. - `hooks/src/engine/discovery.rs`, which projects effective enablement into `hooks/list` from source-derived managedness. - `config/src/hook_config.rs`, which defines the new `hooks.state` representation. - `core/src/session/mod.rs`, which rebuilds live hook state after user config reloads. --------- Co-authored-by: Codex <noreply@openai.com>

Discover hooks bundled with plugins (#19705)
## Why Plugins can bundle lifecycle hooks, but Codex previously only discovered hooks from user, project, and managed config layers. This adds the plugin discovery and runtime plumbing needed for plugin-bundled hooks while keeping execution behind the `plugin_hooks` feature flag. ## What - Discovers plugin hook sources from each plugin's default `hooks/hooks.json`. - Supports `plugin.json` manifest `hooks` entries as either relative paths or inline hook objects. - Plumbs discovered plugin hook sources through plugin loading into the hook runtime when `plugin_hooks` is enabled. - Marks plugin-originated hook runs as `HookSource::Plugin`. - Injects `PLUGIN_ROOT` and `CLAUDE_PLUGIN_ROOT` into plugin hook command environments. - Updates generated schemas and hook source metadata for the plugin hook source. ## Stack 1. This PR - openai/codex#19705 2. openai/codex#19778 3. openai/codex#19840 4. openai/codex#19882 ## Reviewer Notes - Core logic is in `codex-rs/core-plugins/src/loader.rs` and `codex-rs/hooks/src/engine/discovery.rs` - Moved existing / adding new tests to `codex-rs/core-plugins/src/loader_tests.rs` hence the large diff there - Otherwise mostly plumbing and minor schema updates ### Core Changes The `codex-rs/core` changes are limited to wiring plugin hook support into existing core flows: - `core/src/session/session.rs` conditionally pulls effective plugin hook sources and plugin hook load warnings from `PluginsManager` when `plugin_hooks` is enabled, then passes them into `HooksConfig`. - `core/src/hook_runtime.rs` adds the `plugin` metric tag for `HookSource::Plugin`. - `core/config.schema.json` picks up the new `plugin_hooks` feature flag, and `core/src/plugins/manager_tests.rs` updates fixtures for the added plugin hook fields. --------- Co-authored-by: Codex <noreply@openai.com>

Support MCP tools in hooks (#18385)
## Summary Lifecycle hooks currently treat `PreToolUse`, `PostToolUse`, and `PermissionRequest` as Bash-only flows - hook schema constrains `tool_name` to `Bash` - hook input assumes a command-shaped `tool_input` - core hook dispatch path passes only shell command strings That means hooks cannot target MCP tools even though MCP tool names are model-visible and stable This change generalizes those hook paths so they can match and receive payloads for MCP tools while preserving the existing Bash behavior. ## Reviewer Notes I think these are the key files - `codex-rs/core/src/tools/handlers/mcp.rs` - `codex-rs/core/src/mcp_tool_call.rs` Otherwise the changes across apply_patch, shell, and unified_exec are mainly to rewire everything to be `tool_input` based instead of just `command` so that it'll make sense for MCP tools. ## Changes - Allow `PreToolUse`, `PostToolUse`, and `PermissionRequest` hook inputs to carry arbitrary `tool_name` and `tool_input` values instead of hard-coding `Bash` and command-only payloads. - Add MCP hook payload support through `McpHandler`, using the model-visible tool name from `ToolInvocation` and the raw MCP arguments as `tool_input`. - Include MCP tool responses in `PostToolUse` by serializing `McpToolOutput` into the hook response payload. - Run `PermissionRequest` hooks for MCP approval requests after remembered approval checks and before falling back to user-facing MCP elicitation. - Preserve exact matching for literal hook matchers like `Bash` and `mcp__memory__create_entities`, while keeping regex matcher support for patterns like `mcp__memory__.*` and `mcp__.*__write.*`. --------- Co-authored-by: Andrei Eternal <eternal@openai.com> Co-authored-by: Codex <noreply@openai.com>

fix(core): emit hooks for apply_patch edits (#18391)
Fixes https://github.com/openai/codex/issues/16732. ## Why `apply_patch` is Codex's primary file edit path, but it was not emitting `PreToolUse` or `PostToolUse` hook events. That meant hook-based policy, auditing, and write coordination could observe shell commands while missing the actual file mutation performed by `apply_patch`. The issue also exposed that the hook runtime serialized command hook payloads with `tool_name: "Bash"` unconditionally. Even if `apply_patch` supplied hook payloads, hooks would either fail to match it directly or receive misleading stdin that identified the edit as a Bash tool call. ## What Changed - Added `PreToolUse` and `PostToolUse` payload support to `ApplyPatchHandler`. - Exposed the raw patch body as `tool_input.command` for both JSON/function and freeform `apply_patch` calls. - Taught tool hook payloads to carry a handler-supplied hook-facing `tool_name`. - Preserved existing shell compatibility by continuing to emit `Bash` for shell-like tools. - Serialized the selected hook `tool_name` into hook stdin instead of hardcoding `Bash`. - Relaxed the generated hook command input schema so `tool_name` can represent tools other than `Bash`. ## Verification Added focused handler coverage for: - JSON/function `apply_patch` calls producing a `PreToolUse` payload. - Freeform `apply_patch` calls producing a `PreToolUse` payload. - Successful `apply_patch` output producing a `PostToolUse` payload. - Shell and `exec_command` handlers continuing to expose `Bash`. Added end-to-end hook coverage for: - A `PreToolUse` hook matching `^apply_patch$` blocking the patch before the target file is created. - A `PostToolUse` hook matching `^apply_patch$` receiving the patch input and tool response, then adding context to the follow-up model request. - Non-participating tools such as the plan tool continuing not to emit `PreToolUse`/`PostToolUse` hook events. Also validated manually with a live `codex exec` smoke test using an isolated temp workspace and temp `CODEX_HOME`. The smoke test confirmed that a real `apply_patch` edit emits `PreToolUse`/`PostToolUse` with `tool_name: "apply_patch"`, a shell command still emits `tool_name: "Bash"`, and a denying `PreToolUse` hook prevents the blocked patch file from being created.

Add PermissionRequest hooks support (#17563)
## Why We need `PermissionRequest` hook support! Also addresses: - https://github.com/openai/codex/issues/16301 - run a script on Hook to do things like play a sound to draw attention but actually no-op so user can still approve - can omit the `decision` object from output or just have the script exit 0 and print nothing - https://github.com/openai/codex/issues/15311 - let the script approve/deny on its own - external UI what will run on Hook and relay decision back to codex ## Reviewer Note There's a lot of plumbing for the new hook, key files to review are: - New hook added in `codex-rs/hooks/src/events/permission_request.rs` - Wiring for network approvals `codex-rs/core/src/tools/network_approval.rs` - Wiring for tool orchestrator `codex-rs/core/src/tools/orchestrator.rs` - Wiring for execve `codex-rs/core/src/tools/runtimes/shell/unix_escalation.rs` ## What - Wires shell, unified exec, and network approval prompts into the `PermissionRequest` hook flow. - Lets hooks allow or deny approval prompts; quiet or invalid hooks fall back to the normal approval path. - Uses `tool_input.description` for user-facing context when it helps: - shell / `exec_command`: the request justification, when present - network approvals: `network-access <domain>` - Uses `tool_name: Bash` for shell, unified exec, and network approval permission-request hooks. - For network approvals, passes the originating command in `tool_input.command` when there is a single owning call; otherwise falls back to the synthetic `network-access ...` command. <details> <summary>Example `PermissionRequest` hook input for a shell approval</summary> ```json { "session_id": "<session-id>", "turn_id": "<turn-id>", "transcript_path": "/path/to/transcript.jsonl", "cwd": "/path/to/cwd", "hook_event_name": "PermissionRequest", "model": "gpt-5", "permission_mode": "default", "tool_name": "Bash", "tool_input": { "command": "rm -f /tmp/example" } } ``` </details> <details> <summary>Example `PermissionRequest` hook input for an escalated `exec_command` request</summary> ```json { "session_id": "<session-id>", "turn_id": "<turn-id>", "transcript_path": "/path/to/transcript.jsonl", "cwd": "/path/to/cwd", "hook_event_name": "PermissionRequest", "model": "gpt-5", "permission_mode": "default", "tool_name": "Bash", "tool_input": { "command": "cp /tmp/source.json /Users/alice/export/source.json", "description": "Need to copy a generated file outside the workspace" } } ``` </details> <details> <summary>Example `PermissionRequest` hook input for a network approval</summary> ```json { "session_id": "<session-id>", "turn_id": "<turn-id>", "transcript_path": "/path/to/transcript.jsonl", "cwd": "/path/to/cwd", "hook_event_name": "PermissionRequest", "model": "gpt-5", "permission_mode": "default", "tool_name": "Bash", "tool_input": { "command": "curl http://codex-network-test.invalid", "description": "network-access http://codex-network-test.invalid" } } ``` </details> ## Follow-ups - Implement the `PermissionRequest` semantics for `updatedInput`, `updatedPermissions`, `interrupt`, and suggestions / `permission_suggestions` - Add `PermissionRequest` support for the `request_permissions` tool path --------- Co-authored-by: Codex <noreply@openai.com>

core: remove cross-crate re-exports from lib.rs (#16512)
## Why `codex-core` was re-exporting APIs owned by sibling `codex-*` crates, which made downstream crates depend on `codex-core` as a proxy module instead of the actual owner crate. Removing those forwards makes crate boundaries explicit and lets leaf crates drop unnecessary `codex-core` dependencies. In this PR, this reduces the dependency on `codex-core` to `codex-login` in the following files: ``` codex-rs/backend-client/Cargo.toml codex-rs/mcp-server/tests/common/Cargo.toml ``` ## What - Remove `codex-rs/core/src/lib.rs` re-exports for symbols owned by `codex-login`, `codex-mcp`, `codex-rollout`, `codex-analytics`, `codex-protocol`, `codex-shell-command`, `codex-sandboxing`, `codex-tools`, and `codex-utils-path`. - Delete the `default_client` forwarding shim in `codex-rs/core`. - Update in-crate and downstream callsites to import directly from the owning `codex-*` crate. - Add direct Cargo dependencies where callsites now target the owner crate, and remove `codex-core` from `codex-rs/backend-client`.

[hooks] add non-streaming (non-stdin style) shell-only PostToolUse support (#15531)

Little wave report: - echo 'one' completed and returned one. - echo '[block-pre-tool-use]' was blocked before execution by the PreToolUse hook. - echo '[block-post-tool-use]' ran, but its result was blocked afterward by the PostToolUse hook. The hook messages were: - PreToolUse demo blocked the command. Remove [block-pre-tool-use] to continue. - PostToolUse demo blocked the result after execution. Remove [block-post-tool-use] to continue. › for the blocked messages (correctly blocked in this test) did the tool output land back into context? • Yeah, from this run: - PreToolUse block: the command itself did not execute, so no command output landed in context. Only the block message did. - PostToolUse block: the command did execute, but the actual stdout did not come back into context. Only the post-tool block message did. So the blocked notifications landed in context, but the blocked command payloads themselves did not. Nice clean guardrail, aloha. ```
