Shipped — v0.1.0¶

Milestone	What landed
Foundation	Repo, license, CI matrix on Python 3.11 / 3.12 / 3.13, project scaffolding
Core proxy	OpenAI adapter, `record` / `replay` / `auto` modes, JSONL cassette format
Streaming	SSE capture with millisecond timing fidelity, `--timing realtime / fast / slow=N`
Multi-provider	Anthropic + Gemini adapters, path-based and explicit prefix routing
Smart matching	`exact` / `normalized` / `ignore-fields` / `fuzzy` (optional sentence-transformers)
Redaction	Capture-time secret + PII scrubbing, post-hoc `reel redact`, pre-commit hook
pytest plugin	Auto-registered via `pytest11`, `reel_cassette` fixture, `@cassette` decorator, `--reel-mode`
Analytics CLI	`reel inspect / cost / diff / stats / doctor` over cassette JSONL
Observability	Structured per-request JSON logs (`--log-format json`)
Web inspector	`reel ui` — local HTMX cassette browser
Distribution	PyPI publish via Trusted Publishing, docs site on GitHub Pages, Homebrew formula scaffold

See the architecture overview for how the pieces fit together.

These are tracked as ideas; comment on a GitHub issue if you'd use any of them and want to push them up the queue.

Zero-config onboarding — reel up / reel down / eval "$(reel env)" so users never set env vars by hand.
reel run -- <cmd> — wrapper that auto-spawns the proxy for one subprocess and tears it down on exit.
Embedding-cache mode — transparent dedupe of /v1/embeddings calls (model-keyed, cross-session). Pure win, zero risk.
MCP server — exposes lookup_cassette / report_savings / embed_cached as tools that agents can wire in deliberately.
TypeScript SDK + vitest plugin
Auto-instrumentation packages for LangChain / LlamaIndex / AI SDK
Tool-call multi-turn matching for agent loops
Snapshot mode — assert response shape rather than exact content
More provider adapters: Bedrock, Vertex, Azure OpenAI, Mistral, Groq, Cerebras, Together
Reel Cloud (eventually) — team cassette sharing + dashboards, only if there's demand
