CHANGELOG.md

Changelog

0.9.1

• Fix: Claude Code session discovery on Windows — workspace-to-project-dir matching is now case-insensitive on win32 (#57, part of #4)
  • VS Code reports drive letters lowercase (c:\...) while Claude Code encodes them uppercase (C--...), so the encoded-directory lookup, the subfolder-session prefix check, and the cwd containment check could all silently miss — no sessions appeared at all
  • The workspace project dir is now resolved to its actual on-disk casing at startup, and all path comparisons are case-folded on Windows (matching the Codex-side fix from 0.9.0)

0.9.0

• New model support — Claude Fable 5 / Mythos 5, Sonnet 5, Opus 4.8, GPT-5.x Codex (#57)
  • Context window sizing: fable/mythos family recognized as 1M context (previously fell back to 200k, showing the gauge 5× overfull); gpt-* family recognized as 400k as the fallback when Codex doesn't report its own authoritative window. Sonnet 5 / Opus 4.8 already matched the existing family patterns
  • Cost display: per-model-family blended $/M rates (Fable/Mythos $10/$50, Opus $5/$25, Sonnet $3/$15, Haiku $1/$5, GPT-5.x Codex $1.75/$14) replace the single Sonnet-class rate that was applied to every agent. Agents now carry the detected model ID, and the cost pill, summary panel, and per-tool breakdown all use the owning agent's rate
• Codex session discovery fixes — addresses reports of Codex sessions not appearing
  • Windows: workspace/cwd matching is now case-insensitive on win32 (VS Code reports c:\..., Codex writes C:\... — sessions never matched)
  • Large session_meta: the first-line reader now grows up to 1MB instead of a fixed 64KB — newer Codex versions embed full base instructions and AGENTS.md content, which silently broke cwd extraction and skipped the session
  • Silent cwd mismatch: when recent Codex sessions exist but none ran in the current workspace, a warning now says so (the most common cause: launching npx agent-flow-app from a different directory than the Codex session). Warnings are visible without --verbose
• Fix: assistant messages in Codex sessions were labeled "CLAUDE" in the transcript panels and canvas bubbles — the label now follows the session runtime ("CODEX") (#49)

0.8.1

• Opt-out anonymous usage telemetry — Agent Flow now tracks whether people come back after day 1 so we can tell whether it's actually useful. Only aggregate session metadata is sent, never prompts, file paths, or code
  • What's sent: session count, duration, event count, OS/arch, Agent Flow version, distinct Claude/Codex model IDs observed during each session, which runtimes were watched (claude, codex, or claude,codex), and error class names on crashes
  • What's NEVER sent: prompts, tool calls, tool responses, file paths, repo names, user name/email/hostname, environment variables, error messages or stack traces
  • Turn off: export AGENT_FLOW_TELEMETRY=false or export DO_NOT_TRACK=1. Disabled installs write nothing to disk — no ~/.agent-flow/ state file, no telemetry dir
  • Only the published npx agent-flow-app binary emits. pnpm run dev stays silent so contributor iterations don't land in the data
  • Inspect the exact payload locally: cat ~/.agent-flow/telemetry/events.jsonl
• Remove @vercel/analytics — conflicts with the first-party-only commitment in the privacy doc

0.8.0

• Codex runtime support — available in all three entry points: VS Code extension, pnpm run dev, and npx agent-flow-app. Agent Flow now watches Codex rollouts at ~/.codex/sessions/**/rollout-*.jsonl alongside Claude Code sessions
  • New agentVisualizer.runtime setting (VS Code only): "auto" (default, watches both), "claude", or "codex"
  • AGENT_FLOW_RUNTIME environment variable (claude / codex / auto) gives the same opt-out in pnpm run dev and npx agent-flow-app
  • Respects CODEX_HOME for non-default installs
  • Parses all five Codex rollout record types (session_meta, turn_context, response_item, event_msg, compacted) — surfaces tool calls (exec_command, apply_patch, write_stdin, update_plan), reasoning, web searches
  • Uses Codex's own authoritative token counts (event_msg.token_count.info.last_token_usage.input_tokens and model_context_window) instead of estimating
  • Handles auto-compaction via the compacted event — context gauge resets cleanly instead of staying frozen
  • Filters Codex's IDE-context wrapper (# Context from my IDE setup: + ## My request for Codex:) and pure injections (AGENTS.md, environment_context, turn_aborted) from user messages
• Refactor: new AgentSessionWatcher interface and shared watcher→panel wiring (session-runtime.ts) replaces per-runtime duplication. The Codex watcher is vscode-free so it works in the relay/CLI without modification
• Parser unit test suite with real-shape rollout fixture — run via pnpm test

0.7.0

• Opus 4.7 support (#43)
  • Context window sizing now uses family-based pattern matching, so new Opus/Sonnet releases (4.7, future 4.x / 5.x) pick up their 1M context without a code change
  • Redacted thinking blocks (Opus 4.7 returns thinking as an encrypted signature by default) now show a "Thinking..." placeholder bubble instead of being silently dropped
• Fix: Windows hook deduplication — isAgentFlowHook now normalizes path separators before matching, so old entries are correctly replaced on re-registration (prevents settings.json from accumulating duplicates) (#42)
• Fix: respect CLAUDE_CODE_DISABLE_1M_CONTEXT env var and setting — context gauge caps to 200k when set (#39)
• Fix: relay path encoding for non-ASCII workspace paths (CJK, Cyrillic, accented Latin) (#38)
• Fix: duplicate subagent nodes from hook server and transcript parser race (#34)
• Fix: duplicate React key warning on session switch (#33)
• Fix: web app SSE connection failure in standalone dev mode (#32)

0.6.2

• Fix: session detection for workspace paths containing underscores or other special characters (#18, #19)

0.6.1

• npx support — npx agent-flow-app starts the visualizer without cloning the repo
• Internal refactor: shared relay module and build config

0.6.0

• Standalone web app — run Agent Flow in the browser without VS Code (pnpm run dev)
• pnpm workspace monorepo setup
• VS Code debug and dev configuration
• Fix: event loss from React strict mode double-invocation
• Fix: SSE relay security hardening (localhost-only binding, restricted CORS, bounded event buffer)

0.5.0

• Fix: heavy performance degradation during long sessions with many agents (#20)
  • Decouple canvas rendering from React state — canvas reads from a ref at 60fps, React re-renders only on data changes
  • Virtualize transcript and message feed panels for constant render cost regardless of message count
  • Replace timeline panel DOM with canvas rendering
  • Fix tool call cleanup leak that caused unbounded object growth after ~5000 events
  • Fix event log cap causing mass event replay in mock/stress mode
  • Cap simulation loop at 60fps to reduce CPU/GPU usage
• Add stress test scenarios for profiling (?stress=light|medium|heavy|extreme)
• Add performance overlay for debugging (?perf)
• Fix passive event listener warning when panning canvas
• File attention panel: show agent count instead of full name list

0.4.7

• Fix: reset button in review mode no longer breaks the extension
  • Active agents are preserved across reset; only completed state and visual history are cleared
  • Event log is trimmed to retain agent_spawn events so review mode seeking works correctly

0.4.6

• Updated README: clarified automatic hook configuration behavior
• Updated description and tagline

0.4.5

• Initial public release
• Real-time visualization of Claude Code agent execution flows
• Auto-detection of Claude Code sessions via transcript watching
• Claude Code hooks integration for live event streaming
• Multi-session support with session tabs
• Interactive canvas with agent nodes, tool calls, and particles
• Timeline, file attention, and transcript panels
• JSONL event log file watching
