Provider-neutral context control plane for coding agents

manicure

manifest + curate. Care for the cargo your coding agent carries.

A provider-neutral context control plane for coding agents. Sits as a reverse proxy in front of Claude, captures every /v1/messages exchange, normalises payloads into an internal representation, runs them through a deterministic curation pipeline, and optionally pauses for manual editing in a schema-aware editor.

No cert install. No system proxy settings. No sudo.

Install

uv tool install manicure     # recommended
pipx install manicure        # alternative

Or via the bootstrap script (installs uv first if missing):

curl -fsSL https://github.com/srobinson/manicure/releases/latest/download/install.sh | bash

Quick start

# Start the workbench (proxy + web UI)
manicure start

# In another terminal, point your coding agent at it
ANTHROPIC_BASE_URL=http://localhost:8787 claude

Open http://localhost:8788 to see the live log, the rules UI, and the breakpoint editor.

What it does

Every /v1/messages request your agent sends gets:

1. Captured — full request and response, logged to ~/.manicure/exchanges/.
2. Curated — a deterministic pipeline applies your rules (strip tools, truncate system parts, rewrite descriptions, drop thinking blocks).
3. Paused (optional) — arm the breakpoint to edit the next request in a schema-aware editor before it forwards upstream.

All visible in a web UI at http://localhost:8788.

Why

A single Claude Code session routinely sends 285 KB payloads: 147 tools, 3 system parts, 5 message turns. Tools alone account for 67% of that. Manicure gives you visibility into what's being sent, a pipeline to strip and rewrite it, and a breakpoint to intervene before it hits the API.
