* Plugins: add native ask dialog for before_tool_call hooks
Extend the before_tool_call plugin hook with a requireApproval return field
that pauses agent execution and waits for real user approval via channels
(Telegram, Discord, /approve command) instead of relying on the agent to
cooperate with a soft block.
- Add requireApproval field to PluginHookBeforeToolCallResult with id, title,
description, severity, timeout, and timeoutBehavior options
- Extend runModifyingHook merge callback to receive hook registration so
mergers can stamp pluginId; always invoke merger even for the first result
- Make ExecApprovalManager generic so it can be reused for plugin approvals
- Add plugin.approval.request/waitDecision/resolve gateway methods with
schemas, scope guards, and broadcast events
- Handle requireApproval in pi-tools via two-phase gateway RPC with fallback
to soft block when the gateway is unavailable
- Extend the exec approval forwarder with plugin approval message builders
and forwarding methods
- Update /approve command to fall back to plugin.approval.resolve when exec
approval lookup fails
- Document before_tool_call requireApproval in hooks docs and unified
/approve behavior in exec-approvals docs
* Plugins: simplify plugin approval code
- Extract mergeParamsWithApprovalOverrides helper to deduplicate param
merge logic in before_tool_call hook handling
- Use idiomatic conditional spread syntax in toolContext construction
- Extract callApprovalMethod helper in /approve command to eliminate
duplicated callGateway calls
- Simplify plugin approval schema by removing unnecessary Type.Union
with Type.Null on optional fields
- Extract normalizeTrimmedString helper for turn source field trimming
* Tests: add plugin approval wiring and /approve fallback coverage
Fix 3 broken assertions expecting old "Exec approval" message text.
Add tests for the /approve command's exec→plugin fallback path,
plugin approval method registration and scope authorization, and
handler factory key verification.
* UI: wire plugin approval events into the exec approval overlay
Handle plugin.approval.requested and plugin.approval.resolved gateway
events by extending the existing exec approval queue with a kind
discriminator. Plugin approvals reuse the same overlay, queue management,
and expiry timer, with branched rendering for plugin-specific content
(title, description, severity). The decision handler routes resolve calls
to the correct gateway method based on kind.
* fix: read plugin approval fields from nested request payload
The gateway broadcasts plugin approval payloads with title, description,
severity, pluginId, agentId, and sessionKey nested inside the request
object (PluginApprovalRequestPayload), not at the top level. Fix the
parser to read from the correct location so the overlay actually appears.
* feat: invoke plugin onResolution callback after approval decision
Adds onResolution to the requireApproval type and invokes it after
the user resolves the approval dialog, enabling plugins to react to
allow-always vs allow-once decisions.
* docs: add onResolution callback to requireApproval hook documentation
* test: fix /approve assertion for unified approval response text
* docs: regenerate plugin SDK API baseline
* docs: add changelog entry for plugin approval hooks
* fix: harden plugin approval hook reliability
- Add APPROVAL_NOT_FOUND error code so /approve fallback uses structured
matching instead of fragile string comparison
- Check block before requireApproval so higher-priority plugin blocks
cannot be overridden by a lower-priority approval
- Race waitDecision against abort signal so users are not stuck waiting
for the full approval timeout after cancelling a run
- Use null consistently for missing pluginDescription instead of
converting to undefined
- Add comments explaining the +10s timeout buffer on gateway RPCs
* docs: document block > requireApproval precedence in hooks
* fix: address Phase 1 critical correctness issues for plugin approval hooks
- Fix timeout-allow param bug: return merged hook params instead of
original params when timeoutBehavior is "allow", preventing security
plugins from having their parameter rewrites silently discarded.
- Host-generate approval IDs: remove plugin-provided id field from the
requireApproval type, gateway request, and protocol schema. Server
always generates IDs via randomUUID() to prevent forged/predictable
ID attacks.
- Define onResolution semantics: add PluginApprovalResolutions constants
and PluginApprovalResolution type. onResolution callback now fires on
every exit path (allow, deny, timeout, abort, gateway error, no-ID).
Decision branching uses constants instead of hard-coded strings.
- Fix pre-existing test infrastructure issues: bypass CJS mock cache for
getGlobalHookRunner global singleton, reset gateway mock between tests,
fix hook merger priority ordering in block+requireApproval test.
* fix: tighten plugin approval schema and add kind-prefixed IDs
Harden the plugin approval request schema: restrict severity to
enum (info|warning|critical), cap timeoutMs at 600s, limit title
to 80 chars and description to 256 chars. Prefix plugin approval
IDs with `plugin:` so /approve routing can distinguish them from
exec approvals deterministically instead of relying on fallback.
* fix: address remaining PR feedback (Phases 1-3 source changes)
* chore: regenerate baselines and protocol artifacts
* fix: exclude requesting connection from approval-client availability check
hasExecApprovalClients() counted the backend connection that issued
the plugin.approval.request RPC as an approval client, preventing
the no-approval-route fast path from firing in headless setups and
causing 120s stalls. Pass the caller's connId so it is skipped.
Applied to both plugin and exec approval handlers.
* Approvals: complete Discord parity and compatibility fallback
* Hooks: make plugin approval onResolution non-blocking
* Hooks: freeze params after approval owner is selected
* Gateway: harden plugin approval request/decision flow
* Discord/Telegram: fix plugin approval delivery parity
* Approvals: fix Telegram plugin approval edge cases
* Auto-reply: enforce Telegram plugin approval approvers
* Approvals: harden Telegram and plugin resolve policies
* Agents: static-import gateway approval call and fix e2e mock loading
* Auto-reply: restore /approve Telegram import boundary
* Approvals: fail closed on no-route and neutralize Discord mentions
* docs: refresh generated config and plugin API baselines
