Radar brief — 2026-10-09

What the evidence shows

GitHub/changelog-style notes are the majority of this brief (~54% trusted mix). Two sources in the window reported errors; treat HTML changelogs (Factory Droid docs, Augment VS Code notes) as secondary to versioned GitHub tags. Several large notes set bodyOmitted — only listed changes are cited.

For developers

1. If you use Claude Code daily, update through v2.1.293–v2.1.295. Use claude-haiku-5-5 when you want the new default Haiku (1M context; watch the >100K token price step). Recheck /model effort — wrapping could previously save Low as a default. If you write mods, isDeferred: false on $.tool.register puts the schema in the prompt immediately. Prefer onFailure: "block" on command/HTTP hooks when a failed hook must not silently allow the action. Re-test instruction-style prompt/agent hooks after v2.1.294.

2. Cline users: treat desktop-v0.0.45 as a reliability + model-default release. If Vertex AI (or the other listed providers) suddenly feels cheaper/faster and less “Sonnet-like,” you were likely flipped to Haiku 5.5 — pin the model you actually want. SSH remote users should skip anything from 0.0.38 up to this fix. CLI users: change cline dashboard → cline hub dashboard; drop the now-unknown schedule/history flags; re-run cline mcp add if a remote server lost Authorization headers.

3. Codex CLI rust-v0.162.0: enable worktrees only on trusted local projects; confirm Linux deny-globs and Windows 10 path access if you sandbox. Custom Responses providers can now turn on live web access and remote compaction — configure those explicitly.

4. Antigravity 1.3.2: if you used --dangerously-skip-permissions to rush /plan, plans wait for review again. Browse /plugin before pasting MCP/skill bundles by hand.

5. Copilot CLI v1.0.94: Haiku 5.5 is selectable. If bypass-permission flags stop working, look for the new managed-settings warning rather than assuming a CLI bug.

6. Terminal UX: Claude Code v2.1.295, Crush v0.98.0, and Factory Droid v0.236.0 all advertise OSC 7501 (working / waiting / done). Useful if your terminal implements it; ignore if not.

7. Stay off prereleases unless you opt in: Zed v1.24.1-pre, Copilot v1.0.95-2, Augment v1.2.0-prerelease.*. Zed stable in this window is v1.23.2.

For teams

1. Model-default drift is the team risk today. Cline desktop-v0.0.45 changes defaults for Vertex AI, GitHub Copilot, and several gateways to Haiku 5.5. Copilot CLI and Goose also add Haiku 5.5. Pin models in org/provider settings before the next billing cycle; do not assume “whatever the catalog defaulted last week.”

2. Permission flags are being tightened, not loosened. Antigravity’s --dangerously-skip-permissions no longer rubber-stamps implementation plans. Copilot CLI managed policy can disable Assisted Permissions and suppress startup bypass flags (with a visible warning). Factory Droid now prompts when script input is built at runtime. Audit CI wrappers and “YOLO” aliases.

3. MCP and hooks are still crashy surfaces — but several hosts just patched them. Cline (CLI/desktop/SDK) no longer dies ~3s after an MCP server or hook exits unread; Claude Code fixed an HTTP MCP leak that retained every request. Re-roll those versions on shared machines before debugging “random CLI exits.”

4. Plugin / skill distribution is expanding. Antigravity’s official marketplace plus Claude Code warnings when plugin commands write to a settings file that does not load: review what gets installed org-wide, and confirm the target settings file actually loads.

5. Kilo Code JetBrains v7.1.9 renames workflows → commands and splits agent guidance into skills. Update internal docs and the bundled CLI pin (v7.8.8).

6. Open radar proposals still sit at P5–P2 (Cline provider pins / .clinerules, Qwen hosted MCP, utility-model cost, Devin/Windsurf Fusion pins, Grok CLI harness, OpenCode verification videos). None of those are substitutes for the shipped versions above.

What to ignore

• Augment v1.2.0-prerelease.202610081519: install URLs and unsigned SEA metadata, not a behavior changelog.
• Omitted tails (+132, +80, +54, …): do not infer unlisted breaking changes.
• Crush’s release-letter tone (“Good luck, Charm XX”): the evidence is OSC 7501, Grok OAuth, and MCP ping — not a platform strategy shift.
• Factory Droid HTML changelog vs GitHub tags: useful, but it is the noisier source class in this mix.
• Zed v1.24.1-pre and Copilot v1.0.95-2 unless you are on the pre channel.
• Internal judge scores, “mustKnow” as evidence, or any assistant/version not in the JSON.

Watch next

• Whether Haiku 5.5 default flips spread beyond Cline’s listed providers and Claude’s own Haiku default — especially GitHub Copilot surfaces.
• Hook fail-closed behavior (onFailure: "block") and Antigravity’s plan-approval change: expect broken automation that assumed skip-permissions meant skip-review.
• OSC 7501 showing up in three CLIs in one window — terminal vendors and status-line scripts.
• Codex worktrees + sandbox follow-ups (large omitted tail; Linux/Windows permission fixes already landed).
• Zed v1.24.1 stable if Agent Panel terminal-drag and Bedrock custom-model work graduate from -pre.
• The six open proposals, especially team-scoped Cline model pins and Qwen hosted MCP.

How to use DevAgentRadar

This brief is a public snapshot of shipped evidence, not a vendor ranking. Prefer the GitHub/tag rows; treat HTML changelogs and prereleases as weaker. isNew = last 36 hours; mustKnow is a usage-ranking hint, not extra proof. If a note says bodyOmitted, stop at the listed lines. Developers: pin models and re-test hooks/MCP after the versions above. Teams: lock defaults and permission flags in managed settings, then ignore marketing and omitted tails until they appear as versioned facts.
