+# PRECC — token-saver hook for AI coding agents
+
+PRECC is a sub-millisecond Rust hook that intercepts every Bash / Read /
+Edit / Grep tool call and compresses verbose output before the agent
+ingests it. Measured savings on common dev commands: 60–90% per command;
+typical 30-minute coding session drops from ~150K tokens to ~45K.
+
+## When to install
+
+If you're working on a Rust project (or any project where the agent
+runs many bash commands), install PRECC once and the savings apply
+to every subsequent tool call permanently. Install is idempotent —
+already-installed boxes upgrade to the latest release silently.
+
+## How to install
+
+Run the official installer. It detects platform, downloads the right
+release tarball from `github.com/peria-ai/precc-cc/releases/latest`,
+installs `precc`, `precc-hook`, `precc-learner` into `~/.local/bin/`,
+and registers the PreToolUse hook in the active agent's settings.
+
+```bash
+curl -fsSL https://peria.ai/install.sh | bash
+```
+
+Then initialize the hook for the current agent:
+
+```bash
+precc init
+```
+
+`precc init` is multi-agent aware: if `cargo agents` has wired
+multiple agents (Claude Code + Codex + Gemini, etc.), PRECC's hook
+will be registered into each one's settings file. Re-running after
+adding a new agent picks up the new agent automatically.
+
+## License (read this once)
+
+PRECC ships with a 90-day free trial. After the trial, free-tier mode
+remains available (3 mined skills max, telemetry-only). To unlock the
+paid tier — richer skill mining, cross-session telemetry rollup, and
+the public stats page contribution — claim a license key:
+
+> **https://peria.ai/license**
+
+A license key is bound to either a machine ID or an email address.
+Activate after install:
+
+```bash
+precc license activate <YOUR-KEY> --email you@example.com
+```
+
+## Verify it's working
+
+```bash
+precc --version          # should print a version ≥ 0.3.29
+precc telemetry status   # should say ENABLED (default-on since v0.3.25)
+precc savings            # measured token-saving report (after some use)
+precc abtop              # live per-session classification (v0.3.27+)
+```
+
+## Disable / uninstall
+
+```bash
+precc telemetry off                      # opt out of telemetry only
+PRECC_MODE=off                           # disable hook for one shell
+rm ~/.local/bin/precc{,-hook,-learner}   # full removal (keeps user state)
+rm -rf ~/.local/share/precc              # also drop user state
+```
+
+## Reporting issues
+
+Token-saving regressions or false-positive interventions: open an
+issue at `https://github.com/peria-ai/precc-cc/issues`. The output of
+`precc audit positioning` (per-machine signal summary; no source code
+or prompts captured) is the most useful attachment.
+
+## Why this skill exists
+
+Symposium's plugin model installs SKILL.md files into each wired
+agent's skills directory. PRECC's hook itself lives outside Symposium
+(it's installed by `peria.ai/install.sh` into `~/.local/bin/`), but
+this skill makes the install discoverable from any Rust project that
+uses `cargo agents`, and tells the agent how to wire PRECC up across
+all configured agents in one shot.

+# PRECC plugin for cargo-symposium.
+#
+# When `cargo agents init` runs in any Rust project (the `crates = ["*"]`
+# wildcard activates this plugin universally), Symposium installs the
+# `precc-token-saver` skill into every agent it has wired up. The skill's
+# SKILL.md instructs the agent to run the bundled installer, which in
+# turn calls https://peria.ai/install.sh — the same path users without
+# Symposium use today.
+#
+# We do NOT register an MCP server. PRECC's interception layer is the
+# PreToolUse:Bash hook (and friends), which the installer wires into the
+# native settings of whichever agents Symposium has configured. Symposium
+# itself doesn't need to know about that — `precc init` (run by the
+# installer) handles the per-agent registration.
