Radar brief — 2026-08-25

What the evidence shows

15 signals across 23 tracked assistants. GitHub/changelog-style sources are only 49% of the mix, one feed reported errors, and several high-score notes omit large tails (bodyOmitted up to 154). Treat the table as the shipped surface, not a complete changelog.

Higher-confidence GitHub releases

Lower-confidence HTML/docs changelogs

For developers

• Upgrade Claude Code to v2.1.234 before the next long Windows or subagent session. The NT-namespace reject is a real security fix, and the background-permission plus post-compaction sandbox-network fixes stop “I already answered that” loops. If a host isolates each session’s config dir, set CLAUDE_CODE_PROJECT_DIR_NAME so transcripts stay short and findable. If you do not want a paused thread to resume itself after a claude.ai limit reset, turn Continue automatically at usage limit off in /config the same day you upgrade.
• If you are on Codex, skip 0.148 and land on rust-v0.149.0. Use /export for reviewable Markdown, codex exec fork / the resume picker for branchy work, and codex queue plus codex agents instead of opening another terminal. After resume/fork, verify the restored permission profile — 0.149 says it no longer silently falls back to whatever your current defaults are. Script health with codex doctor before blaming the model. Bedrock users can point at the built-in provider rather than a sidecar.
• Goose v1.46.0 is the cost-and-loop release. Watch the per-message cost/TTFT panel, disable built-in skills you do not want injected, and confirm Stop hooks now receive working_dir. Do not invent behavior from the 103 omitted items.
• Cline SDK users should re-test skills and hooks on sdk/v0.0.76. /my-skill is no longer pasted as a full SKILL.md blob; PreToolUse context reaches the model again; PostToolUse is awaited (120s) and can cancel. If you wrap Claude Code as a provider, tool activity that used to vanish should now show as observational events — update any log parsers that assumed silence meant “no tools.”
• Antigravity 1.1.12 is the scripting release. Prefer -p "/changelog" / --output-format json over driving an agent turn for inventory. Mark helper skills with disable-slash-command: true so the / menu stays usable.
• Do not treat Zed v1.15.0 as an agent-platform bump. The agent evidence is a terminal-output clip fix; the rest is editor/git/JSX.
• OpenCode v1.18.22 is a compatibility patch, useful if Bedrock or OpenAI-compatible providers were erroring on textVerbosity. It is not a workflow release.
• Ignore the second Kiro 2.19.1 stub and the omitted tails. If a note is not in the visible body, it is not in this brief.

For teams

• Decide the usage-limit policy on Claude Code. Auto-continue after a claude.ai reset is convenient for overnight agents and expensive if nobody is watching. Pair that with the new email-use instruction: Claude is told to use account email only to identify the user, not to ship it to unrelated services unless asked — still not a data-governance control.
• Codex is now a multi-session control plane. Budget for Bedrock routing and in-TUI credit estimates; require rust-v0.149.0 if you rely on resumed approval policies. Teach the team codex queue rather than parallel unmanaged TUIs.
• Keep Cline Cloud handoff in a beta lane. /handoff needs repo/branch/commit already pushed and can keep working after the laptop closes. That is a productivity win and a secret-sprawl risk. Do not make it default until the feature flag, receipt link, and retry path are in your runbook.
• Factory v0.199.0 is the enterprise-controls release to review this week. Set BYOK custom models as managed defaults for sessions and subagents, then add service-account model policies. The matching open proposal is Set BYOK custom models as managed defaults for sessions and subagents (team, P3). Explorer droids can now run read-only commands, web search, and MCP — file edits stay blocked, but “read-only” plus shell is still a data-exfil surface. Also plan for MiniMax M2.5 disappearing in v0.193.0.
• Tabnine v6.5.3 is worth the admin pass even though the source is a rolling docs page: org-level repositories, corrected per-team model assignment, and (from the same page’s 6.5.0 notes) CLI governance that gates YOLO on PAT scope.
• Windsurf MCP auth fixes for self-hosted GitLab / older Atlassian are HTML-only. Validate in a canary org before declaring MCP “fixed.”
• Kiro stream-recovery defaults (60s warn, 300s cancel, 60-minute hard stream timeout) need an explicit team setting review if you run long spec sessions. There is a team proposal: Kiro v2.19.1 (P4). Okta/Entra for Kiro Web is on the same noisy page — confirm against your IdP admin, not this brief alone.
• Open proposals still open: Grok CLI prompt rename (developer, P5), drop legacy managed MCP configs and shadowed platform skills in Grok CLI (everyone, P5), and OpenCode PR #38252 verification videos (everyone, P2). None of those are shipped releases in this evidence pack.

What to ignore

• Marketing tone, “+N more changes,” and any behavior not in the visible release body.
• The duplicate empty Kiro 2.19.1 signal (score 62, no tags). Same version is already covered by the richer changelog entry.
• OpenCode’s removed first-month discount copy — pricing-page cleanup, not a capability change.
• Zed v1.15.0 as an MCP/agent platform story. Tags say agent/mcp; the written evidence does not.
• Windsurf and Tabnine pages that collapse several dates/versions into one blob. Only v3.7.25 / v6.5.3 are the headline versions; older bullets on those pages are mixed in.
• Cline desktop-v0.0.15-beta.1 as production policy until it leaves beta.
• Invented model launches. Codex’s Bedrock note says GPT-5.6 routing support, not that this brief independently verified a new public model drop.
• The one error-reporting source in this window. If a feed failed, do not backfill it from memory or vendor blogs.

Watch next

• Whether Codex agents + queue becomes the default multi-agent HUD, and whether permission-profile restore holds up on remote sessions.
• Whether Cline /handoff graduates from feature-flag beta with a non-push failure mode that is still safe.
• Copycat NT-namespace / NTLM hardening in other Windows-capable CLIs after Claude Code v2.1.234.
• Goose cache-token accounting vs Codex thread-credit estimates — first credible way to compare agent $ / turn in the TUI itself.
• Factory BYOK defaults and the Grok CLI legacy MCP / shadowed skills proposals actually merging.
• Cleanup of the Kiro duplicate feed and the unidentified erroring source. Until both are quiet, HTML Kiro/Windsurf/Tabnine dates stay provisional.

How to use DevAgentRadar

DevAgentRadar is a free, evidence-first radar for AI coding assistants. Read the versioned GitHub rows first, then the HTML/docs rows as unconfirmed. If a change is not in the JSON evidence, it did not happen in this brief — including the omitted tails. Use For developers as personal upgrade/test actions and For teams as policy, identity, MCP, and spend actions. Check the five open proposals before filing the same request upstream. Re-run the radar on the next window rather than stacking rumor on top of a 49% trusted mix.
