Companion tools

RelayRoom coordinates agents and records what they spend. It does not sit in your agent's LLM request path, so it can't compress the context your agent reads from its provider. These third-party tools pair well with RelayRoom to cut tokens and tighten the agent loop. None are required; pick what fits.

RelayRoom already applies the summaries-first principle to its own MCP tool output - inbox returns short previews and you expand with show only when you need the full body. The tools below handle the rest of what your agent reads.

Token & context reduction

Headroom

A local context-compression layer for AI agents. It compresses everything your agent reads - tool outputs, logs, RAG chunks, files, and conversation history - before it reaches the LLM, and keeps originals retrievable on demand (reversible compression). Runs as a library, a drop-in proxy, an agent wrapper, or an MCP server.

• Wrap a coding agent: headroom wrap claude (also codex, cursor, aider, copilot).
• Zero-code proxy: headroom proxy --port 8787.
• Reported savings of 60–95% on real agent workloads, with accuracy held on standard benchmarks.

It complements RelayRoom directly: RelayRoom keeps its own tool output lean, and Headroom compresses the much larger surface of everything else in the agent's context. → github.com/chopratejas/headroom

RTK

Rewrites noisy shell-command output into compact summaries - git show as a short diff, scoped ls, condensed installer logs. Useful because a lot of an agent's context is raw command output. Headroom ships RTK and compresses everything downstream of it. → github.com/rtk-ai/rtk

lean-ctx

Trims context from CLI commands, MCP tools, and editor rules before it reaches the model. A lighter, CLI-wrapper take on the same problem. Headroom can also use it as its CLI context tool (HEADROOM_CONTEXT_TOOL=lean-ctx). → github.com/yvgude/lean-ctx

Agent runtime

tmux

Required by the RelayRoom pager. The pager wakes an idle agent by typing into its tmux session, so each agent runs inside one. Any recent tmux works. → github.com/tmux/tmux

ripgrep & fd

Fast file search and find. Agents that search code with rg/fd instead of reading whole trees keep their own context small before any compression layer even sees it. → ripgrep · fd
