feat(coding-agent): added coding-agent approval types and mode options
- Added `ToolTier`, `ToolApproval`, and `ToolApprovalDecision` types and exported approval APIs. - Updated approval-mode options from `auto|prompt|custom` to `always-ask|write|yolo` and defaulted mode to `yolo`. - Changed approval resolution to apply per-tool decisions first, then mode-tier limits, with legacy-mode migration. - Assigned read/write/exec `approval` and approval-detail prompts across built-in, custom, extension, and MCP tools.

# Tool Approval Policies
|
||||
# Tool approval mode
|
||||
|
||||
Per-tool approval policies allow fine-grained control over which tools require user confirmation before execution.
|
||||
Tool approval has two independent inputs:
|
||||
|
||||
## Overview
|
||||
1. **Tool declaration** — every tool may declare an `approval` tier:
|
||||
- `read`: reads data or updates UI-only session metadata.
|
||||
- `write`: mutates workspace/session state but does not execute arbitrary code.
|
||||
- `exec`: executes code, shells out, drives a browser, spawns agents, or performs similarly broad actions.
|
||||
2. **User policy** — `tools.approval.<toolName>: allow | deny | prompt` overrides the mode for that tool.
|
||||
|
||||
Approval is gated by **two** settings:
|
||||
Tools without an `approval` declaration are treated as `exec`. This is the safe default for MCP and unknown custom tools.
|
||||
|
||||
1. **`tools.approvalMode`** — the top-level switch. Defaults to `auto`.
|
||||
- `auto` (default) — skip approval entirely. **`tools.approval` is ignored.**
|
||||
- `prompt` — apply the built-in per-tool defaults (read-only allowed, destructive prompts). `tools.approval` is still ignored.
|
||||
- `custom` — your `tools.approval.<tool>` config wins; built-in defaults fill in tools you didn't configure.
|
||||
2. **`tools.approval`** — the per-tool policy map. **Only consulted when `tools.approvalMode: custom`.**
|
||||
## Modes
|
||||
|
||||
The CLI flag `--auto-approve` (alias `--yolo`) always wins, regardless of mode.
|
||||
Configure with `tools.approvalMode`:
|
||||
|
||||
> **Common pitfall:** setting `tools.approval.bash: prompt` without setting `tools.approvalMode: custom` is a silent no-op. The default `auto` mode skips the approval layer wholesale.
|
||||
| Mode | Auto-approves | Prompts for |
|
||||
| --- | --- | --- |
|
||||
| `always-ask` | `read` | `write`, `exec` |
|
||||
| `write` | `read`, `write` | `exec` |
|
||||
| `yolo` (default) | `read`, `write`, `exec` | nothing unless a tool declares `override: true` |
|
||||
|
||||
> **⚠ Subagent caveat:** the `task` tool spawns a subagent that always runs with `tools.approvalMode: auto` because it has no UI to prompt against. Anything `task` is asked to do — including `bash`, `write`, `eval` — runs unattended once the parent `task` call is approved. The single approval prompt on `task` is the chokepoint; the prompt now shows the agent id and assignment so you can decide what you're authorizing. See [Subagents](#subagents) below.
|
||||
`--auto-approve` and `--yolo` force `tools.approvalMode: yolo` for the session. They do **not** bypass tool safety overrides.
|
||||
|
||||
### Built-in defaults (mode `prompt` / `custom`)
|
||||
## User overrides
|
||||
|
||||
- **Read-only tools** (read, find, search, ast_grep, web_search, recall, inspect_image, job) are auto-allowed.
|
||||
- **Destructive tools** (bash, write, edit, ast_edit, debug, browser, eval, task, ssh, retain, reflect, checkpoint, rewind) require approval.
|
||||
- **External/custom tools** (MCP, extensions) require approval.
|
||||
- **LSP** prompts by default, but read-only actions (`diagnostics`, `definition`, `references`, `hover`, `symbols`, …) are auto-allowed.
|
||||
- **Debug** prompts by default, but inspection actions (`threads`, `stack_trace`, `variables`, `scopes`, `read_memory`, …) are auto-allowed.
|
||||
- **Critical bash patterns** always prompt, even if bash is allowlisted — except when you explicitly `deny` bash, in which case the deny still wins.
|
||||
|
||||
### Action-Based Exceptions
|
||||
|
||||
Some tools have **action-based exceptions** that apply policy based on specific inputs:
|
||||
|
||||
**LSP Tool** (performance optimization):
|
||||
- Default policy: `prompt`
|
||||
- Exception: read-only actions → auto-allowed
|
||||
- Result: `diagnostics`, `hover`, `references` don't prompt; `rename`, `code_actions` do prompt
|
||||
|
||||
**Bash Tool** (safety override):
|
||||
- Default policy: `prompt`
|
||||
- Exception: critical patterns → force prompt (overrides user `allow`)
|
||||
- Result: `rm -rf /`, `sudo rm`, fork bombs always prompt when bash is `allow` or unset; a user `bash: deny` still wins.
|
||||
|
||||
## Quick Start
|
||||
|
||||
### Bypass all approvals for automation
|
||||
|
||||
```bash
|
||||
omp --auto-approve -p "Fix all TypeScript errors"
|
||||
omp --yolo -p "Refactor the auth module"
|
||||
```
|
||||
|
||||
### Enable per-tool prompts for interactive work
|
||||
|
||||
Per-tool policies require **both** the mode switch and the policy map. Add to `~/.omp/agent/config.yml` or `.omp/config.yml`:
|
||||
`tools.approval` is honored in every mode:
|
||||
|
||||
```yaml
|
||||
tools:
|
||||
approvalMode: custom # REQUIRED — without this, `tools.approval` is ignored
|
||||
approvalMode: write
|
||||
approval:
|
||||
bash: allow # Never prompt for bash
|
||||
write: prompt # Always prompt for write
|
||||
edit: allow # Never prompt for edit
|
||||
custom-tool: deny # Block a custom tool entirely
|
||||
bash: prompt
|
||||
read: allow
|
||||
mcp__filesystem__delete: deny
|
||||
```
|
||||
|
||||
## Configuration
|
||||
Resolution per tool call:
|
||||
|
||||
### `tools.approvalMode`
|
||||
1. Compute the tool's approval decision from `tool.approval(args)`; omitted means `exec`.
|
||||
2. If the decision has `override: true`:
|
||||
- `tools.approval.<tool>: deny` blocks the call.
|
||||
- every other policy prompts, even in `yolo`.
|
||||
3. Otherwise, a valid `tools.approval.<tool>` value wins.
|
||||
4. Otherwise, the active mode auto-approves or prompts by tier.
|
||||
|
||||
| Value | Behavior |
|
||||
| -------- | ------------------------------------------------------------------------- |
|
||||
| `auto` | (default) Skip approval. `tools.approval` is **not** consulted. |
|
||||
| `prompt` | Use built-in per-tool defaults. `tools.approval` is **not** consulted. |
|
||||
| `custom` | Use `tools.approval.<tool>`; fall back to built-in defaults for the rest. |
|
||||
Invalid policy values are ignored and fall back to the tool tier/mode decision.
|
||||
|
||||
### Policy Values (under `tools.approval.<tool>`)
|
||||
## Safety overrides
|
||||
|
||||
- `allow` — Auto-approve (never prompt)
|
||||
- `deny` — Block the tool entirely (throws error)
|
||||
- `prompt` — Require user confirmation (default for destructive tools)
|
||||
A tool can force a prompt with object-form approval:
|
||||
|
||||
### Resolution Order (mode `custom`)
|
||||
|
||||
1. **Overriding** action exceptions (safety rules) — but a user `deny` still wins.
|
||||
2. User config for the specific tool (`tools.approval.<toolName>`), validated — invalid values fall through.
|
||||
3. **Non-overriding** action exceptions (performance optimizations).
|
||||
4. Built-in default for the tool (see `DEFAULT_APPROVAL_POLICIES`).
|
||||
5. User-supplied `_default` (only consulted for tools with no built-in default — MCP/custom).
|
||||
6. System-wide fallback (`prompt`).
|
||||
|
||||
### Critical Pattern Override
|
||||
|
||||
Dangerous bash patterns **always** prompt when bash is `allow` or unset:
|
||||
|
||||
```bash
|
||||
rm -rf /
|
||||
sudo rm -rf
|
||||
:(){ :|:& };:
|
||||
chmod -R 777 /
|
||||
```ts
|
||||
approval: { tier: "exec", override: true, reason: "Critical pattern detected" }
|
||||
```
|
||||
|
||||
These patterns force confirmation even if `tools.approval.bash: allow` is set. If you set `tools.approval.bash: deny`, the deny wins — the override never re-arms a denied tool.
|
||||
`bash` uses this for critical destructive patterns such as `rm -rf /`, fork bombs, remote-fetch-then-execute, writes to `/etc/passwd`, and host shutdown commands. These prompt even in `yolo`; in non-interactive/headless sessions they fail instead of running unattended.
|
||||
|
||||
## Non-Interactive Mode
|
||||
## Per-tool prompt details
|
||||
|
||||
When approval is required but no UI is available (e.g., RPC mode, `--mode json`), the tool throws:
|
||||
Tools can add approval-prompt body lines with `formatApprovalDetails(args)`. The standard prompt includes:
|
||||
|
||||
- `Allow tool: <name>`
|
||||
- `Origin: MCP server tool` for unannotated `mcp__...` tools
|
||||
- `Reason: <reason>` when the tool decision supplies one
|
||||
- tool-specific details such as command, path, code, browser action, or subagent assignment
|
||||
|
||||
## Defining approval on tools
|
||||
|
||||
Built-in and custom tools share the same shape:
|
||||
|
||||
```ts
|
||||
export type ToolTier = "read" | "write" | "exec";
|
||||
export type ToolApprovalDecision = ToolTier | { tier: ToolTier; reason?: string; override?: boolean };
|
||||
export type ToolApproval = ToolApprovalDecision | ((args: unknown) => ToolApprovalDecision);
|
||||
|
||||
approval?: ToolApproval;
|
||||
formatApprovalDetails?: (args: unknown) => string | string[] | undefined;
|
||||
```
|
||||
Tool "bash" requires approval but no interactive UI available.
|
||||
Options:
|
||||
1. Use --auto-approve flag
|
||||
2. Set tools.approvalMode: auto in config (default)
|
||||
3. Set tools.approvalMode: custom and add tools.approval.bash: allow
|
||||
|
||||
Examples:
|
||||
|
||||
```ts
|
||||
approval: "read"
|
||||
|
||||
approval: args => LSP_READONLY_ACTIONS.has(args.action) ? "read" : "write"
|
||||
|
||||
approval: args => isCritical(args.command)
|
||||
? { tier: "exec", override: true, reason: "Critical pattern detected" }
|
||||
: "exec"
|
||||
```
|
||||
|
||||
## Subagents
|
||||
|
||||
Subagents launched by the `task` tool always run with `tools.approvalMode: auto` regardless of parent settings, because they have no UI to prompt against. The user's approval of the parent `task` call is the authorization for the subagent's work — configure the parent to gate task dispatch (`tools.approval.task: prompt` under `tools.approvalMode: custom`) if you want a chokepoint.
|
||||
|
||||
## Automated Workflows
|
||||
|
||||
For CI/CD or scripted workflows, use `--auto-approve`:
|
||||
|
||||
```bash
|
||||
# GitHub Actions
|
||||
omp --auto-approve --no-session -p "Run tests and fix linting"
|
||||
|
||||
# Cron job
|
||||
omp --yolo -p "Update dependencies and commit"
|
||||
```
|
||||
|
||||
## Security Considerations
|
||||
|
||||
- **Trust your prompts**: `--auto-approve` bypasses all safety checks
|
||||
- **Review allowlists**: Regularly audit `tools.approval` config
|
||||
- **Critical patterns**: Cannot be `allow`-ed away (this is intentional); `deny` still wins
|
||||
- **External tools**: Require approval by default (no built-in allowlist)
|
||||
- **Subagents**: Inherit auto-approve unconditionally — the chokepoint is the parent `task` call.
|
||||
|
||||
## Examples
|
||||
|
||||
### Allow bash and write for local development
|
||||
|
||||
```yaml
|
||||
# .omp/config.yml (project-local)
|
||||
tools:
|
||||
approvalMode: custom
|
||||
approval:
|
||||
bash: allow
|
||||
write: allow
|
||||
```
|
||||
|
||||
### Deny browser tool in shared environments
|
||||
|
||||
```yaml
|
||||
# ~/.omp/agent/config.yml (user-global)
|
||||
tools:
|
||||
approvalMode: custom
|
||||
approval:
|
||||
browser: deny
|
||||
```
|
||||
|
||||
### Selective automation
|
||||
|
||||
```bash
|
||||
# Auto-approve for known-safe operations
|
||||
omp --auto-approve --tools read,find,grep -p "Analyze codebase"
|
||||
|
||||
# Manual approval for destructive changes
|
||||
omp -p "Refactor authentication module"
|
||||
```
|
||||
|
||||
## Migration from Extensions
|
||||
|
||||
If you previously used a custom extension for approval (e.g., `confirm-destructive.ts`), you can:
|
||||
|
||||
1. **Remove the extension** — built-in approval supersedes it
|
||||
2. **Migrate allowlists** — convert extension config to `tools.approval.*` and set `tools.approvalMode: custom`
|
||||
3. **Test behavior** — verify prompts appear as expected
|
||||
|
||||
Example migration:
|
||||
|
||||
```typescript
|
||||
// Old extension: ~/.omp/agent/extensions/confirm-destructive.ts
|
||||
const ALLOWED_TOOLS = ["read", "find", "search"];
|
||||
```
|
||||
|
||||
```yaml
|
||||
# New config: ~/.omp/agent/config.yml
|
||||
tools:
|
||||
approvalMode: custom
|
||||
approval:
|
||||
bash: prompt
|
||||
write: prompt
|
||||
edit: prompt
|
||||
# read/find/search already auto-allowed by default
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### "I set `tools.approval.bash: prompt` but nothing prompts"
|
||||
|
||||
**Problem**: `tools.approvalMode` is still at its `auto` default, which ignores `tools.approval`.
|
||||
|
||||
**Solution**: Add `tools.approvalMode: custom` to the same config file.
|
||||
|
||||
### "Tool requires approval but no UI available"
|
||||
|
||||
**Problem**: Running in non-interactive mode (RPC, JSON, headless) with approval required.
|
||||
|
||||
**Solution**:
|
||||
- Add `--auto-approve` flag, or
|
||||
- Set `tools.approvalMode: auto` (or back to the default), or
|
||||
- Set `tools.approvalMode: custom` and `tools.approval.<tool>: allow`
|
||||
|
||||
### Prompts appear for read-only tools
|
||||
|
||||
**Problem**: Custom or MCP tools may not be recognized as read-only.
|
||||
|
||||
**Solution**:
|
||||
```yaml
|
||||
tools:
|
||||
approvalMode: custom
|
||||
approval:
|
||||
custom-readonly-tool: allow
|
||||
```
|
||||
|
||||
### Critical pattern bypass attempt
|
||||
|
||||
**Problem**: `rm -rf /` prompts even though bash is allowlisted.
|
||||
|
||||
**Behavior**: **This is intentional**. Critical patterns cannot be auto-approved via `tools.approval.bash: allow`. If you genuinely want to block bash entirely, use `tools.approval.bash: deny` — that wins over the override.

|
||||
Subagents run headless with `tools.approvalMode: yolo` so they do not stall waiting for UI. The parent `task` approval is the authorization boundary. Tool-level safety overrides still apply; a critical override inside a headless subagent fails rather than running without confirmation.

### Added
|
||||
|
||||
- Added per-tool approval declarations so each built-in, custom, or extension tool can declare its capability tier and approval prompt details.
|
||||
- Added `OMP_MCP_TIMEOUT_MS` environment variable to override MCP client request timeout for every server (in milliseconds); set to `0` to disable client-side timeouts. Invalid (negative or non-numeric) values are ignored with a warning and fall back to the per-server timeout or default 30s ([#1415](https://github.com/can1357/oh-my-pi/pull/1415)).
|
||||
- Added interactive provider selection to `omp auth-broker logout` when no provider argument is supplied
|
||||
- Added `--json` flag to `omp auth-broker list` for machine-readable output
|
||||
- Added `omp auth-broker list` to enumerate supported OAuth providers (replaces `bunx @oh-my-pi/pi-ai list`).
|
||||
- Added interactive provider selection to `omp auth-broker login` and `omp auth-broker logout` when no provider argument is supplied (replaces `bunx @oh-my-pi/pi-ai login` / `logout` interactive flows).
|
||||
- Added `omp auth-broker list` (with `--json` for machine-readable output) to enumerate supported OAuth providers, replacing `bunx @oh-my-pi/pi-ai list`.
|
||||
- Added interactive provider selection to `omp auth-broker login` and `omp auth-broker logout` when invoked without a provider argument (replacing the equivalent `bunx @oh-my-pi/pi-ai login`/`logout` flows). The logout picker is sourced from stored credentials so it only lists providers the user is actually signed in to.
|
||||
- Added directory matches to the `find` tool: glob searches now return directories alongside files, with directory hits emitted with a trailing `/` marker. `find` for `**/tests` no longer requires a follow-up `read` to surface a directory hit; tool prompt and output docs were updated to reflect that paths may be either kind.
|
||||
- Added the RFC 8414 §3.1 path-ful issuer form (`/.well-known/oauth-authorization-server<issuer-path>`) as a third candidate in MCP OAuth discovery, after origin-root and path-prefixed well-known URLs, so deployments that publish authorization-server metadata at the path-ful location resolve correctly. Single-segment authorization URLs (e.g. `https://gateway/my-service`) are now treated as the gateway prefix instead of being dropped back to the origin root.
|
||||
|
||||
### Changed
|
||||
|
||||
- Changed tool-approval prompts to use an explicit `Approve`/`Deny` selector and show the denial reason as contextual help text
|
||||
- Changed `omp auth-broker login` to support interactive provider selection when invoked without a provider argument
|
||||
- Changed `omp auth-broker logout` to support interactive provider selection from stored credentials when invoked without a provider argument
|
||||
- Changed `omp auth-broker login` to drive the per-provider OAuth/API-key flow in-process via `AuthStorage.login()` instead of spawning the `pi-ai` CLI subprocess. The pi-ai bin is being removed; the same login surface now lives entirely inside `omp`.
|
||||
- Changed default per-line truncation cap for search/grep output (`DEFAULT_MAX_COLUMN`) from `1024` to `512` characters.
|
||||
- Changed tool-approval prompts to use an explicit `Approve`/`Deny` selector and surface the denial reason as contextual help text instead of a bare confirm/cancel toggle.
|
||||
- Changed approval safety overrides to prompt even in `yolo` / `--auto-approve` sessions, so critical tool-declared patterns no longer run unattended.
|
||||
- Changed `omp auth-broker login` to drive the per-provider OAuth/API-key flow in-process via `AuthStorage.login()` instead of spawning the `pi-ai` CLI subprocess. The `pi-ai` bin is being removed; the same login surface now lives entirely inside `omp`.
|
||||
- Changed the default per-line truncation cap for search/grep output (`DEFAULT_MAX_COLUMN`) from `1024` to `512` characters to keep wide minified single-line bundles from blowing out the model's context.
|
||||
|
||||
### Fixed
|
||||
|
||||
- Fixed the agent loop and bash executor busy-spinning when scheduler waits returned early. napi `uv_async_send` callbacks can wake the event loop after only ~1–2 ms even when the caller asked for a longer sleep, so `yieldIfDue()` now compensates by retrying `Bun.sleep()` until the requested wall-clock duration has elapsed, and the bash executor wraps its `runPromise`/timeout/abort race in an `ExponentialYield` (20 ms → 10 s) so long-running commands stop hot-looping on the race. Yields are additionally throttled by a module-level 50 ms gate, and losing timers in the race are aborted via `AbortSignal` so they don't keep firing after a winner is selected ([#1396](https://github.com/can1357/oh-my-pi/pull/1396) by [@hezhiyang2000](https://github.com/hezhiyang2000), closes [#1384](https://github.com/can1357/oh-my-pi/issues/1384)).
|

- Fixed streaming edit previews going blank for inline-payload ops. `LINE↓payload` / `A-B:payload` are valid single-line writes, but the natural-order preview was skipping the entire op token until a newline arrived — so the first character the model typed after the sigil only appeared after the next line ended, and the renderer would fall back to rendering the raw `A-B: bla bla bla` input. Inline-body content on `op-insert` and `op-replace` tokens is now emitted as a `+payload` line on the same op tick.
|
||||
- Fixed `/usage` and the status-line reset countdown rendering stale negative deltas after a Codex window had elapsed: Codex keeps reporting the prior window's `reset_at` until a new request opens a fresh window, which turned the `resets in …` suffix into a meaningless negative duration. `formatDuration` now clamps non-positive, NaN, and infinite inputs to `0ms`, and both renderers suppress the `resets in …` suffix entirely once `resetsAt <= now`.

* Tool approval policies for safe mode.

* Tool approval resolution.
|

*
|
||||
* VSCode-style per-tool approval with:
|
||||
* - Built-in defaults (read-only tools auto-allowed, destructive tools require approval)
|
||||
* - User allowlist via config (`tools.approval.<toolName>: allow|deny|prompt`)
|
||||
* - Action-based exceptions (tool-level policy can be overridden for specific actions)
|
||||
* - CLI override (`--auto-approve` / `--yolo`) bypasses all prompts
|
||||
*
|
||||
* Resolution is intentionally minimal and pure — no I/O, no async, no settings
|
||||
* lookups inside this module. Callers thread a plain user-config record in and
|
||||
* read the resulting `{ required, reason }` shape.
|
||||
* Approval policy is declared by each tool. This module only knows how to:
|
||||
* - normalize user `tools.approval.<tool>: allow | deny | prompt` overrides,
|
||||
* - compare a tool capability tier against the active approval mode,
|
||||
* - format the generic approval prompt body.
