Content Quality: 713 words (News range 400-1200). Clear Overview / What We Know / What We Don't Know / Analysis structure. Specifics (Ctrl double-tap, temporary worktrees, cloud runs for orgs with AI seats, per-session cost, privacy statements, Junie Lite) all trace to the JetBrains post.
Source Verification: Read all three snapshots from disk (gunzip). manifest suspicious_patterns is null for all three; no injection text found. source-0 (blog.jetbrains.com/ai/2026/10/air-in-ides-eap/, 200): confirms EAP as Marketplace plugin or 2026.3 EAP builds; verbatim quote 'is a conduit for agents and subscriptions you already use. It is not an AI provider, and it ships with no agents installed.' appears exactly; Codex, GitHub Copilot, Junie, Cursor and other ACP-compatible agents; Claude subscription in terminal/full-screen tab; no JetBrains AI subscription needed; sessions view, Ctrl double-tap, tabs, worktrees, cloud 'Currently available to orgs with AI seats'; skills/tools list and 'for some tasks, use fewer tokens'; 'We believe... Junie Lite for free'; 'AI Assistant remains available'; 'Over time, we expect Air to become the primary experience'; 'an IDE that keeps agents at arm's length will struggle to stay relevant'; 'Air is a tool window, not an AI provider'; privacy and 'Air adds no new data processing terms'; 'Disable the Air plugin, and nothing else changes'. source-1 (sdtimes.com roundup, Archive.org fallback capture, 200 live): dated October 1, 2026 in the page; says Air is 'an open system of products for agentic development' launching EAP in 2026.3 EAP builds or Marketplace plugin; lists Codex, GitHub Copilot, Junie, Cursor, ACP agents; reproduces the IDE skills/tools paragraph verbatim. The article attributes only these to SD Times and attributes the Oct 1 date to SD Times, not to JetBrains in its own voice (the JetBrains post carries only a /2026/10/ URL and 'Last week/Today'). Details only JetBrains states (cloud, worktrees, privacy, Junie Lite) are attributed to JetBrains. source-2 (blog.jetbrains.com/air/2026/09/introducing-air-teams/): confirms 'team layer for agentic development', available to JetBrains business customers, expansion 'beyond a standalone desktop app' to individuals/teams/organizations, and 10 Automation templates including code review, bug fixes, dependency upgrades, documentation maintenance. Supports only what it is cited for. The 'September' label derives from the URL path; the snapshot text has no explicit date, which is a minor inference.
Factual Accuracy: Title 'Without Bundling an Agent' is supported by 'ships with no agents installed' and 'tool window, not an AI provider'; Air is bring-your-own-agent via detection and ACP. Minor nuance: the FAQ says Air supports Codex, Gemini, GitHub Copilot, Claude Agent and Junie 'out of the box' (integration, not bundling), and Junie Lite free runs require a JetBrains Account; the article's wording ('ships with no agents installed', quoted) stays accurate. Scope: 'JetBrains IDEs' generically; the sources name no specific IDEs or platforms, and the article does not claim any. 'AI Assistant remains available for now' is a fair paraphrase (FAQ: remains available and supported as a separate plugin). Early access, no GA date: correct. Cross-reference: /article/2026-03/25-jetbrains-unveils-central-... exists on disk and states Air entered public preview in March; also 2026-03/16 article covers Air preview. Link form is correct (singular article).
Overall Assessment: Accurate, well-attributed, correctly sourced. Link set matches the sources array exactly (3 external URLs plus one internal article link that resolves). Allowlist: blog.jetbrains.com and sdtimes.com both present. APPROVE.
