From e4a16451ec3c195707c3e964dff5bc91b39a3ffc Mon Sep 17 00:00:00 2001 From: can1357 Date: Tue, 26 May 2026 21:43:23 +0200 Subject: [PATCH] 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. --- docs/approval-mode.md | 275 ++------- packages/agent/CHANGELOG.md | 5 + packages/agent/src/types.ts | 21 + packages/coding-agent/CHANGELOG.md | 24 +- packages/coding-agent/src/cli/args.ts | 6 +- packages/coding-agent/src/commands/launch.ts | 4 +- .../src/config/settings-schema.ts | 34 +- packages/coding-agent/src/config/settings.ts | 3 +- packages/coding-agent/src/edit/index.ts | 26 + .../src/extensibility/custom-tools/types.ts | 16 +- .../src/extensibility/extensions/wrapper.ts | 63 +- packages/coding-agent/src/lsp/index.ts | 39 +- packages/coding-agent/src/sdk.ts | 2 +- packages/coding-agent/src/task/executor.ts | 8 +- packages/coding-agent/src/task/index.ts | 19 + packages/coding-agent/src/tools/approval.ts | 379 ++++-------- packages/coding-agent/src/tools/ask.ts | 1 + packages/coding-agent/src/tools/ast-edit.ts | 26 +- packages/coding-agent/src/tools/ast-grep.ts | 1 + packages/coding-agent/src/tools/bash.ts | 70 ++- packages/coding-agent/src/tools/browser.ts | 15 + packages/coding-agent/src/tools/calculator.ts | 1 + packages/coding-agent/src/tools/checkpoint.ts | 2 + packages/coding-agent/src/tools/debug.ts | 32 + packages/coding-agent/src/tools/eval.ts | 15 + packages/coding-agent/src/tools/find.ts | 1 + packages/coding-agent/src/tools/gh.ts | 22 +- .../src/tools/hindsight-recall.ts | 1 + .../src/tools/hindsight-reflect.ts | 1 + .../src/tools/hindsight-retain.ts | 1 + packages/coding-agent/src/tools/image-gen.ts | 1 + .../coding-agent/src/tools/inspect-image.ts | 1 + packages/coding-agent/src/tools/irc.ts | 1 + packages/coding-agent/src/tools/job.ts | 1 + packages/coding-agent/src/tools/read.ts | 1 + .../coding-agent/src/tools/recipe/index.ts | 1 + .../coding-agent/src/tools/render-mermaid.ts | 1 + .../src/tools/report-tool-issue.ts | 1 + packages/coding-agent/src/tools/resolve.ts | 1 + packages/coding-agent/src/tools/review.ts | 1 + .../src/tools/search-tool-bm25.ts | 1 + packages/coding-agent/src/tools/search.ts | 1 + packages/coding-agent/src/tools/ssh.ts | 8 + packages/coding-agent/src/tools/todo-write.ts | 1 + packages/coding-agent/src/tools/write.ts | 13 +- packages/coding-agent/src/tools/yield.ts | 1 + packages/coding-agent/src/web/search/index.ts | 2 + .../test/tools/approval-mode.test.ts | 94 +-- .../coding-agent/test/tools/approval.test.ts | 564 ++++-------------- 49 files changed, 797 insertions(+), 1011 deletions(-) diff --git a/docs/approval-mode.md b/docs/approval-mode.md index d453d2cef..20b658ca4 100644 --- a/docs/approval-mode.md +++ b/docs/approval-mode.md @@ -1,240 +1,95 @@ -# 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.: allow | deny | prompt` overrides the mode for that tool. -Approval is gated by **two** settings: +Tools without an `approval` declaration are treated as `exec`.

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`. ## [15.4.3] - 2026-05-26 diff --git a/packages/coding-agent/src/cli/args.ts b/packages/coding-agent/src/cli/args.ts index 8ff145f5a..6aaf5941d 100644 --- a/packages/coding-agent/src/cli/args.ts +++ b/packages/coding-agent/src/cli/args.ts @@ -47,7 +47,7 @@ export interface Args { listModels?: string | true; noTitle?: boolean; autoApprove?: boolean; - approvalMode?: "auto" | "prompt" | "custom"; + approvalMode?: "always-ask" | "write" | "yolo"; messages: string[]; fileArgs: string[]; /** Unknown flags (potentially extension flags) - map of flag name to value */ @@ -178,12 +178,12 @@ export function parseArgs(args: string[], extensionFlags?: Map` overrides. - // "custom" — your `tools.approval.` config wins.
