Radar brief — 2026-11-03

What the evidence shows

New GitHub/changelog signals first. mustKnow is a ranking hint; the facts below are from the releases themselves. Several notes have omitted bodies — those extra changes are not inferred here. One tracked source reported errors; treat HTML changelogs as noisier than tagged GitHub releases (trusted mix this brief: 54% GitHub/changelog vs HTML).

Last 36 hours (versioned)

Last 36 hours (unversioned HTML)

Still relevant this week (not in the 36-hour window)

For developers

• Kiro 2.37.x: Before the next V3 launch, decide whether auto-migration is acceptable. Files are rewritten in place (.json.bak first). To stay on V2: kiro-cli settings chat.enableAutoAgentUpgrade false. Prefer 2.37.1 for the output-limit notice, idle-CPU fix, and session persistence across CLI upgrades. Set KIRO_RUNTIME_DIR only if you need a non-bundled runtime.
• Claude Code v2.1.317: Expect a prompt when a web/shell tool would send your account email. If you author Agent SDK hooks, set onFailure: "block" so a failed callback cannot let the action through. Self-hosted runners that nest claude -p should set CLAUDE_CODE_DISABLE_NESTED_SESSION_ID=1 if they need the old session/transcript ID behavior. Check /schedule connector warnings before leaving cloud tasks running.
• Copilot CLI v1.0.106-6 (prerelease): Use /settings search. Confirm MCP servers that return user-only images/text — that payload should stay in the TUI, not the model. Failed tool rows now expand; over-budget turns should error instead of looping.
• Qwen Code v0.26.6: Web Shell activity/split-view/token plots are the usable delta. Leave experimental.unifiedAgentLoop off unless you want more ACP turns (channel prompts, Goal-proposal approvals) on the shared loop.
• Kimi Code 2.3.0: Update any skill invocation or docs that used a bare plugin skill name. On model switch mid-thread, choose new session / compact / continue / cancel when the cloud-gated dialog appears.
• Mistral Vibe: If you are on the 3.x line, learn /branch, compaction-threshold UI, and /leanstall. If you need MCP, check that enable_mcp is not admin-disabled. 2.26.1 still matters for /proxy-setup and the background/subagent kill switches.
• Codex (0.166.0, not the empty alpha): Try codex queue --resume for unloaded threads and codex doctor --network-only when connectivity is the question. GPT-6.1 Terra is in the bundled, Vertex, and Bedrock catalogs per that tag — pin it explicitly if you want it.

For teams

• Kiro: Treat 2.37.0 as a fleet event. Auto-upgrade will rewrite shared agent configs. Roll 2.37.1 after 2.37.0. Communicate the opt-out before people open V3 sessions. ACP terminal login is now a supported path for clients that declare it.
• Claude Code: Use the new gateway cost report (GET /v1/organizations/analytics/cost) and the IdP-group daily records (retention admin.identity_retention_days). Watch Desktop Code-tab notices that remote managed settings failed to load — agents may be running without org policy. Fail-closed hooks (onFailure: "block") are the safer default for production SDK wrappers.
• Copilot CLI: The MCP “user-only content stays off the model” change is a privacy control; pair it with the plain-text MCP error rendering (escape sequences can no longer restyle warnings). Still a prerelease tag.
• Sourcegraph Amp: MCP connectors on Agentic Batch Changes expand blast radius to issue trackers and internal docs. Gate which servers agents may call; the “keep chatting while workspaces run” change means the agent turn ends while execution continues — don’t assume the conversation lock equals job completion.
• Factory Droid v1.2.0: API-key revoke now confirms; org-policy timeout false positives are fixed. Remote reconnect-after-sleep reduces dropped agent turns, not policy coverage.
• Mistral Vibe v3.0.0: enable_mcp is an admin kill switch for add/remove/toggle/login/tool registration, including plugin MCP. Decide the org default before developers hit /mcp.
• JetBrains Air Governance livestream is not a ship; do not treat it as a version you can pin.

What to ignore

• OpenAI Codex rust-v0.167.0-alpha.4: empty body. Do not plan around it.
• Augment Code prerelease tag: installer/SEA packaging only; macOS -sea is unsigned in the notes.
• Qwen sdk-typescript-v0.1.27 changelog bulk: mostly historical “bundles CLI version …” lines, not new SDK behavior.
• JetBrains AI blog post: livestream + mixed posts; omitted body. Not evidence of a product change you can deploy.
• Omitted tails (+89, +132, +85, …): do not assume hidden breaking changes or features.
• Internal scores / mustKnow: ranking hints, not facts. Cite the release, not the judge.
• One source in this window reported errors — if a changelog page disagrees with a GitHub tag, prefer the tag.

Watch next

• Codex 0.167.0 proper notes after alpha.4.
• Kiro V2 file rewrites: backup noise, broken custom agents, and how many people set chat.enableAutoAgentUpgrade false.
• Claude Code hook authors adopting onFailure: "block", plus whether the email prompt and /schedule connector warning show up in real cloud tasks.
• Qwen experimental.unifiedAgentLoop leaving experimental.
• Mistral Vibe 3.x enable_mcp defaults in managed config.
• Kimi qualified skill names breaking plugins that still call bare names.
• Open proposals on the radar: Codex queue --resume / GPT-6.1 Terra (developer, P5); Crush thinking/hooks (P4); Cline v4.1.26 model pin (P4); Grok CLI harness (P2); OpenCode PR #38252 videos (P2).

How to use DevAgentRadar

This brief is evidence, not a vendor recap. Use it to decide what to install, pin, or postpone today. Prefer versioned GitHub tags over blogs. If a row has bodyOmitted, read the upstream release before you change production. Developers: apply the concrete flags and breaking names above. Teams: treat auto-migration, MCP connectors, fail-closed hooks, and cost/policy APIs as org changes, not client cosmetics. Re-check the radar after the next 36-hour window — alphas and omitted tails are where the next surprise usually is.
