Small model testing showed the label did not meaningfully help:
- Sub-3B models fail regardless of format
- 8B models untested with label specifically
- Frontier models never needed it
The bracket convention [Wed 2026-01-28 22:30 EST] matches existing
channel envelope format and is widely present in training data.
Saves ~2-3 tokens per message vs the labeled version.
Changes [Wed 2026-01-28 20:30 EST] to [Current Date: Wed 2026-01-28 20:30 EST].
Tested with qwen3-1.7B: even with DOW in the timestamp, the model
ignored it and tried to compute the day using Zeller's Congruence.
The "Current Date:" semantic label is widely present in training data
and gives small models the best chance of recognizing the timestamp
as authoritative context rather than metadata to parse.
Cost: ~18 tokens per message. Prevents hallucination spirals that
burn hundreds or thousands of tokens on date derivation.
Changes [2026-01-28 20:30 EST] to [Wed 2026-01-28 20:30 EST].
Costs ~1 extra token but provides day-of-week for smaller models
that can't derive DOW from a date. Frontier models already handle
it, but this is cheap insurance for 7B-class models.
Replace verbose formatUserTime (Wednesday, January 28th, 2026 — 8:30 PM)
with the same formatZonedTimestamp used by channel envelopes (2026-01-28
20:30 EST). This:
- Saves ~4 tokens per message (~7 vs ~11)
- Uses globally unambiguous YYYY-MM-DD 24h format
- Removes 12/24h config option (always 24h, agent-facing)
- Anchors envelope detection to the actual format function — if channels
change their timestamp format, our injection + detection change too
- Adds test that compares injection output to formatZonedTimestamp directly
Exported formatZonedTimestamp from auto-reply/envelope.ts for reuse.
Verifies that America/New_York correctly resolves to midnight for
both EST (winter, UTC-5) and EDT (summer, UTC-4) using the same
IANA timezone. Intl.DateTimeFormat handles the DST transition.
The chat.send handler (used by webchat and TUI) is a separate path
from the agent handler. Inject timestamp into BodyForAgent (what the
model sees) while keeping Body raw for UI display.
This completes timestamp coverage for all non-channel paths:
- agent handler: spawned subagents, sessions_send, heartbeats
- chat.send: webchat, TUI
Messages arriving through the gateway agent method (TUI, web, spawned
subagents, sessions_send, heartbeats) now get a timestamp prefix
automatically. This gives all agent contexts date/time awareness
without modifying the system prompt (which is cached for stability).
Channel messages (Discord, Telegram, etc.) already have timestamps
via envelope formatting in a separate code path and never reach
the agent handler, so there is no double-stamping risk.
Cron jobs also inject their own 'Current time:' prefix and are
detected and skipped.
Extracted as a pure function (injectTimestamp) with 12 unit tests
covering: timezone handling, 12/24h format, midnight boundaries,
envelope detection, cron detection, and empty messages.
Integration test verifies the agent handler wires it in correctly.

- Add resumeArgs to DEFAULT_CLAUDE_BACKEND for proper --resume flag usage
- Fix gateway not preserving cliSessionIds/claudeCliSessionId in nextEntry
- Add test for CLI session ID preservation in gateway agent handler
- Update docs with new resumeArgs default
* fix(ui): enable save button only when config has changes
The save button in the Control UI config editor was not properly gating
on whether actual changes were made. This adds:
- `configRawOriginal` state to track the original raw config for comparison
- Change detection for both form mode (via computeDiff) and raw mode
- `hasChanges` check in canSave/canApply logic
- Set `configFormDirty` when raw mode edits occur
- Handle raw mode UI correctly (badge shows "Unsaved changes", no diff panel)
Fixes#1609

* feat(gateway-tool): add config.patch action for safe partial config updates
Exposes the existing config.patch server method to agents, allowing safe
partial config updates that merge with existing config instead of replacing it.
- Add config.patch to GATEWAY_ACTIONS in gateway tool
- Add restart + sentinel logic to config.patch server method
- Extend ConfigPatchParamsSchema with sessionKey, note, restartDelayMs
- Add unit test for config.patch gateway tool action
Closes#1617

* feat(discord): add exec approval forwarding to DMs
Add support for forwarding exec approval requests to Discord DMs,
allowing users to approve/deny command execution via interactive buttons.
Features:
- New DiscordExecApprovalHandler that connects to gateway and listens
for exec.approval.requested/resolved events
- Sends DMs with embeds showing command details and 3 buttons:
Allow once, Always allow, Deny
- Configurable via channels.discord.execApprovals with:
- enabled: boolean
- approvers: Discord user IDs to notify
- agentFilter: only forward for specific agents
- sessionFilter: only forward for matching session patterns
- Updates message embed when approval is resolved or expires
Also fixes exec completion routing: when async exec completes after
approval, the heartbeat now uses a specialized prompt to ensure the
model relays the result to the user instead of responding HEARTBEAT_OK.

* fix: reduce log noise for node disconnect/late invoke errors
- Handle both 'node not connected' and 'node disconnected' errors at info level
- Return success with late:true for unknown invoke IDs instead of error
- Add 30-second throttle to skills change listener to prevent rapid-fire probes
- Add tests for isNodeUnavailableError and late invoke handling
* fix: clean up skills refresh timer and listener on shutdown
Store the return value from registerSkillsChangeListener() and call it
on gateway shutdown. Also clear any pending refresh timer. This follows
the same pattern used for agentUnsub and heartbeatUnsub.
* refactor: simplify KISS/YAGNI - inline checks, remove unit tests for internal utilities

* fix(discord): gate autoThread by thread owner
* fix(discord): ack bot-owned autoThreads
* fix(discord): ack mentions in open channels
- Ack reactions in bot-owned autoThreads
- Ack reactions in open channels (no mention required)
- DRY: Pass pre-computed isAutoThreadOwnedByBot to avoid redundant checks
- Consolidate ack logic with explanatory comment
* fix: allow null values in exec.approval.request schema
The ExecApprovalRequestParamsSchema was rejecting null values for optional
fields like resolvedPath, but the calling code in bash-tools.exec.ts passes
null. This caused intermittent 'invalid exec.approval.request params'
validation errors.
Fix: Accept Type.Union([Type.String(), Type.Null()]) for all optional string
fields in the schema. Update test to reflect new behavior.
* fix: align discord ack reactions with mention gating (#1511) (thanks @pvoo)

The frontend fix alone wasn't enough because:
1. serveIndexHtml() was injecting the raw avatar filename into HTML
2. agent.identity.get RPC was returning raw filename, overwriting the
HTML-injected value
Now both paths resolve local file avatars (*.png, *.jpg, etc.) to the
/avatar/{agentId} endpoint URL.
TypeBox Type.Optional(Type.String()) accepts string|undefined but NOT null.
Discord exec was failing with 'resolvedPath must be string' because callers
passed null explicitly. Web UI worked because it skipped the approval request.
Fixes exec approval validation error in Discord-triggered sessions.
