v1.3.181

Highlights

Sub-agent safety: concurrent limit (max 5), result size cap (100KB), zombie
watchdog, and terminal agent purging to prevent OOM and memory leaks.
Budget guard: absolute token consumption warning (200K) and generation speed
indicator (tok/s) in status bar.
Memory curation: automatic dedup, expiry, and classification of memory entries.
Context engineering: adaptive compaction retention, TTL-based memoize cache
invalidation, on_compaction hook, system prompt size warning.
New commands: /tools, /debug export, /cost all, /title.

Concurrent sub-agent limit (max 5): prevents resource exhaustion from spawning
too many parallel agents. Returns clear error when limit reached.
Result size cap (100KB): sub-agent results exceeding 100KB are truncated with a
notice, preventing context window flooding from large file reads.
Activity-based watchdog: cancels sub-agents with no activity for 10 minutes,
preventing zombie processes from consuming concurrency slots.
Terminal agent purging: retains max 20 completed agents, purging oldest to bound
memory growth in long-running sessions.
spawn_agent tool name validation: validates tool names against registry at spawn
time, preventing silent failures from typos.

Absolute token warning: fires once when cumulative output tokens exceed 200K,
catching runaway sessions missed by escalation pattern detection.
Generation speed indicator (tok/s): shows real-time generation throughput in the
status bar during streaming, helping distinguish "thinking" from "slow generation".

Automatic dedup: multiple versions of the same memory prefix (e.g.,
competitor-analysis-2025-07 vs 2026-07-13-r3) — only the latest is loaded.
Expiry: impl-task/-fix/-bug memories expire after 30 days; architecture/design
memories never expire.
Classification: memories are classified and filtered at load time; files are not
deleted, only filtered from the system prompt index.
Diagnostics: debug.Log reports active/expired/deduped counts on each load.

Adaptive compaction retention: recent group retention adjusts dynamically during
compaction based on context fill level.
TTL-based memoize cache invalidation: file edits automatically invalidate
memoize cache entries for the affected path.
on_compaction hook: new lifecycle hook fires when context compaction occurs.
System prompt size warning: warns when system prompt exceeds 15% of context
window.

LLM transient error retry: 429/503 errors retried at agent loop level with max
retry limit.
Checkpoint cache invalidation: /undo and /revert properly invalidate tool caches.
Goroutine leak fix: broker.Stop() called in StopShare to prevent leak.
Goroutine leak fix: P2P transport StopShare broker cleanup.

isSensitivePath expansion: now covers .env and credential files.
Runtime required field validation: high-risk tools validate required fields.
API key leakage prevention: WebUI endpoints JSON no longer exposes keys.

grep sort by path depth: files_with_matches results sorted by relevance.
MCP error messages: include server name for all tool errors.
Swarm BlockedBy enforcement: dependencies enforced during task claiming.
IM panel cleanup: removed redundant "current binding" section from all 14 panels.
Knight skill promoter: uses AtomicWriteFile for safe frontmatter mutation.
