Inspect or resolve pending permission requests.
    
    `const pending = await ctx.permission.list({ sessionID })
    const request = await ctx.permission.get({ sessionID, requestID })
    await ctx.permission.reply({ sessionID, requestID, decision: &quot;once&quot; })`

Replace the session-scoped permission rules. They are evaluated after the agent’s rules, and the last matching rule wins. Child sessions inherit the rules in effect when they are created.

### Sessions

Create or read a session.

    const session = await ctx.session.get({ sessionID })
    const messages = await ctx.session.context({ sessionID })`

List sessions a page at a time. To get the next page, pass `cursor.next` back as `cursor`. The cursor remembers your filters, so you don’t need to repeat them.

### Description

When a parent session has an explicit `external_directory` allow rule (set via SDK `session.create({ permission })` or via the session permission API), spawning a subtask through the task tool creates a child session whose permission ruleset does not contain the inherited `external_directory` allow. The subagent then asks the user for permission to read files in a directory the parent had already approved.

Root cause is in `packages/opencode/src/session/prompt.ts` around line 1228. The task tool calls `prompt()` for the child session with `tools: { task: false, todowrite: false }`. `SessionPrompt.prompt` converts those into per-call permission rules and writes them to `session.permission` via `sessions.setPermission`, replacing whatever was there instead of merging. The child session is created moments earlier by `sessions.create` with the derived rules from `deriveSubagentSessionPermission` (including any inherited `external_directory` allows), and the prompt-time write then clobbers them.

The fix is one line: merge the per-call tool rules into the existing `session.permission` instead of replacing it.

### Plugins

None

### OpenCode version

dev (1.15.x, current upstream/dev as of this report)

### Steps to reproduce

  1. Create a parent session via SDK with `permission: [{ permission: &quot;external_directory&quot;, pattern: &quot;/tmp/foo/*&quot;, action: &quot;allow&quot; }]`.
  2. Send a prompt with a `subtask` part targeting a subagent (e.g. `explore`).
  3. The subagent attempts to read `/tmp/foo/secret.txt`.
  4. A pending `external_directory` permission request is emitted instead of the read succeeding.

After the fix the child session permission contains the inherited `external_directory` allow and the subagent reads the file directly.

Subagent `agent` name is not persisted, so nested subagents lose inherited permission restrictions#30610

## Description

### Description

When the task tool creates a subagent session it does not store the agent name on the new session row. If that subagent spawns its own subagent, the permission resolver reads `parent.agent` to inherit the parent&#39;s restrictions, finds it empty, and drops the parent agent&#39;s edit denies on the grandchild.

The practical effect: a Plan-mode subagent that spawns another subagent ends up with a grandchild that can edit files, even though Plan mode forbids edits.

This is a different root cause from #30527, which is about prompt-time `setPermission` replacing instead of merging the ruleset. Here the `agent` column is never written at session creation, so `deriveSubagentSessionPermission` has nothing to read. Same code area as #26597, #26700, and #26747.

I have a fix that sets the agent name when the subagent session is created.

### OpenCode version

1.15.13

### Steps to reproduce

  1. Use an agent whose permissions deny edits (for example Plan mode).
  2. Have it spawn a subagent via the task tool, and have that subagent spawn another subagent.
  3. The deepest subagent is allowed to edit, because the deny was not inherited.

Resolved on `dev`: `tool/task.ts:151`/`:200` now set `agent: next.name` on the subagent session, so nested subagents inherit the parent agent&#39;s restrictions. Closing.

<excerpt>citeturn0search1 [wordlim: 200] Crawled: today; ### Permissions ... While a prompt runs, OpenCode sends updates from its child sessions as `session/update` notifications on the prompt’s session. ... `parentID`  | `string`  | The ID of the child session’s parent session. ... Permission requests from a child session carry the same key on `toolCall._meta`.

### Commands

After `session/new`, `session/load`, `session/resume`, or `session/fork`, OpenCode sends `available_commands_update` with the directory’s commands and the built-in `compact` command. It sends another update when the commands change.
    
    `{
      &quot;sessionUpdate&quot;: &quot;available_commands_update&quot;,
      &quot;availableCommands&quot;: [{ &quot;name&quot;: &quot;compact&quot;, &quot;description&quot;: &quot;Compact the session&quot; }]
    }`

If a prompt starts with `/` and the name of an available command, OpenCode runs that command with the rest of the text as arguments. OpenCode sends other text that starts with `/` as a normal prompt. `/compact` runs compaction.

### MCP servers

The client can pass stdio and HTTP MCP servers on `session/new`, `session/load`, `session/resume`, and `session/fork`. OpenCode adds them to the session’s directory for the life of the `opencode acp` process, so other sessions in that directory can use them. OpenCode passes HTTP headers through and doesn’t use OAuth for these servers. It doesn’t advertise MCP over SSE, and it doesn’t support MCP over ACP.

Case  | Behavior
--- | ---
Same name as a configured server  | The client’s server replaces the configured one in that directory.
Policies  | `integration.use` rules still apply.
    
    `{ &quot;type&quot;: &quot;http&quot;, &quot;name&quot;: &quot;docs&quot;, &quot;url&quot;: &quot;https://mcp.example.com&quot;, &quot;headers&quot;: [] }`

### Permissions

Permission requests offer three options:
    
    `[
      { &quot;optionId&quot;: &quot;once&quot;, &quot;kind&quot;: &quot;allow_once&quot;, &quot;name&quot;: &quot;Allow once&quot; },
      { &quot;optionId&quot;: &quot;always&quot;, &quot;kind&quot;: &quot;allow_always&quot;, &quot;name&quot;: &quot;Always allow&quot; },
      { &quot;optionId&quot;: &quot;reject&quot;, &quot;kind&quot;: &quot;reject_once&quot;, &quot;name&quot;: &quot;Reject&quot; }
    ]`

When a request changes files, OpenCode includes `diff` content if it can build a preview of the change.

### Child sessions

While a prompt runs, OpenCode sends updates from its child sessions as `session/update` notifications on the prompt’s session. Each update carries `_meta[&quot;opencode/child-session&quot;]`. OpenCode prefixes tool call IDs with `&lt;childSessionId&gt;:`. It prefixes tool call titles with the child session’s title if the child session has one.
    
    `{
      &quot;sessionUpdate&quot;: &quot;tool_call&quot;,
      &quot;toolCallId&quot;: &quot;ses_child:call_1&quot;,
      &quot;title&quot;: &quot;Explore the codebase: src/app.ts&quot;,
      &quot;_meta&quot;: {
        &quot;opencode/child-session&quot;: { &quot;id&quot;: &quot;ses_child&quot;, &quot;parentID&quot;: &quot;ses_123&quot;, &quot;depth&quot;: 1, &quot;title&quot;: &quot;Explore the codebase&quot; }
      }
    }`

Field  | Type  | Description
--- | --- | ---
`id`  | `string`  | The child session’s ID.
`parentID`  | `string`  | The ID of the child session’s parent session.
`depth`  | `number`  | 1 for a child of the prompt’s session, 2 for a child of that child session, and so on.
`title`  | `string`  | The child session’s title. OpenCode omits it when the child session has no title.

Permission requests from a child session carry the same key on `toolCall._meta`. After the prompt ends, OpenCode stops sending child session updates. Permission requests and questions from child sessions still reach the client.

### Retry status

When a model call fails and OpenCode schedules a retry, it sends `session_info_update` with `_meta[&quot;opencode/retry&quot;]`. When the retry starts, OpenCode sends `&quot;opencode/retry&quot;: null`. Clear any retry status when the prompt response arrives.
    
    `{
      &quot;sessionUpdate&quot;: &quot;session_info_update&quot;,
      &quot;_meta&quot;: {
        &quot;opencode/retry&quot;: {
          &quot;attempt&quot;: 1,
          &quot;nextRetryAt&quot;: &quot;2026-10-02T12:00:05.000Z&quot;,
          &quot;error&quot;: { &quot;type&quot;: &quot;provider.rate-limit&quot;, &quot;message&quot;: &quot;Rate limit exceeded&quot;, &quot;status&quot;: 429 }
        }
      }
    }`

Field  | Type  | Description
--- | --- | ---
`attempt`  | `number`  | The retry attempt number.
`nextRetryAt`  | `string`  | The time of the next attempt, in ISO 8601 format.
`error`  | `object`  | Has `type` and `message`. Also has `status` and `response.body` if the provider sent them.

### Compaction marker

If the client doesn’t advertise `session.compaction`, OpenCode reports compaction progress as `session_info_update` with `_meta[&quot;opencode/compaction&quot;]`. OpenCode always uses the marker for child session compactions.
    
    `{
      &quot;sessionUpdate&quot;: &quot;session_info_update&quot;,
      &quot;_meta&quot;: { &quot;opencode/compaction&quot;: { &quot;status&quot;: &quot;started&quot;, &quot;messageId&quot;: &quot;msg_123&quot;, &quot;reason&quot;: &quot;auto&quot; } }
    }`

Field  | Type  | Description
--- | --- | ---
`status`  | `string`  | `started`, `completed`, or `failed`. A cancelled compaction is `failed`.
`messageId`  | `string`  | Pairs a compaction’s start with its end. Treat it as an opaque key.
`reason`  | `string`  | `auto` or `manual`.
`error`  | `object`  | Present when `status` is `failed`. Same shape as the retry `error`.

The marker doesn’t include a summary. An automatic compaction can fail without a `started` marker. When the client loads a session, OpenCode replays each completed or failed compaction as one marker.</excerpt>

Update active child sessions when the runtime policy changes.

OpenCode child sessions inherit permissions when they are created. A root session.update does not refresh existing children. Update each active child session when applying a new policy. Remove stale parent-derived rules such as *: allow, while preserving child-specific restrictions such as task: deny.

The current openCodeChildPermissionRules helper preserves non-deny child rules, so it must not treat an old parent-derived *: allow rule as child-specific.

Review comment at @packages/provider-opencode/src/server/adapter.ts at line
3120:
Update the applyPermissionRules flow to apply a changed runtime policy to each
active OpenCode child session, not just the root session. Adjust
openCodeChildPermissionRules so stale parent-derived `*: allow` rules are
removed while child-specific restrictions such as `task: deny` remain.
