Edgar ArakelyanandClaude Fable 5.1 fe55c94e66 feat(environment): serve an environment manifest as a replay environment
Add rea environment-serve <manifest.json> --evidence <capture.json>
[--host] [--port]: it loads an environment-manifest view and the capture
Evidence it was projected from, refuses a manifest whose parent evidence id
does not match the capture, builds one MCP tool per manifest tool and serves
them over streamable HTTP beside an environment card at
/.well-known/agent-env.json and a data plane at /agentenv that refuses every
method. Each tool call replays the retained record whose path and query
values best match the arguments, cites the record ordinal and evidence id,
marks replayed content as untrusted target content, and truncates bodies
over 256 KiB with a flag. Nothing executes the captured application.

Keep the evidence Analysis runs locally and returns observations, limitations, and unknowns through the CLI and MCP. /mcp-contracts

Start with one command

npx rea-agents setup

Choose your agent, review the planned changes, and approve setup. Native binary analysis can use an existing Hopper, Ghidra, or IDA installation; static JavaScript analysis needs no native analysis engine.

For a first result from an extracted JavaScript application or ASAR:

npx -y rea-agents@latest analyze-javascript-application /absolute/path/to/app --json

See installation and setup for requirements and configuration.

For runtime instrumentation, see the Frida guide.

Task Guides
Inspect native functions, references, or types Native binaries, Go metadata, Rust dependencies, offline ELF layout, recorded crashes
Select a native provider or import format Ghidra semantics, Windows, DOS, raw bytes, MIPS, PSP, NativeAOT, IDA, Kuna, JEB
Analyze JavaScript or Electron artifacts Static analysis, tracing and comparisons, application graph, source recovery
Compare static JavaScript with runtime observations Runtime attribution, reconciliation, Electron observation, Electron fuses
Inspect assemblies, packages, or firmware .NET, Android, Apktool resources, ADB acquisition, Apple, Harmony, firmware, WASM, EVM
Observe or compare a browser scenario CDP observation, scenarios, runtime evidence, historical captures
Serve recorded behavior as an agent environment Agent environments
Trace captured website source Source locations, module traces, script export
Capture and compare a command Process capture
Use CLI/MCP and retain evidence CLI, MCP contracts, agent prompts, obligation ledgers

For development, use testing, client verification, tool design, and releasing. Reconstruction readiness describes a development conformance verifier. The 6.2 migration records that release's compatibility changes; the roadmap tracks future work.
