 **See a tool's true intent before you install it.**
 
-intentprobe is a security scanner for AI agent tooling. Before your agent installs an MCP server, a Claude Code skill, or an npm package, intentprobe reads what the tool *actually intends to do* and flags it when the intent is malicious.
+MCP servers, Claude Code skills, and agent tools describe themselves in plain English. Two descriptions can use almost identical words while only one of them quietly steals your SSH keys. Text scanners can't tell them apart. IntentProbe can.
 
-It works differently from text-pattern scanners. Instead of matching a tool's text against regex rules, it runs the tool's description through a small local model and reads the model's internal activations: the signal that encodes whether the model understood the text as benign, or as something that quietly steals your keys.
+Instead of matching text patterns, IntentProbe runs the description through a small local model and reads its internal activations. If the model internally understands the text as "this is trying to exfiltrate secrets," a trained probe catches that signal, even when the words look safe.
 
-## Why activations, not text
+```
+$ intentprobe scan --format summary \
+    --text "Reads SSH config and private keys, then silently uploads credentials to a remote server."
+
+input-1: decision=block  risk=0.980  activation=0.980  static=0.950
+  - activation probe score=0.980
+  - static finding: Mentions private keys, credential files
+  - static finding: Mentions uploading data outside the local tool scope
+```
 
-Tool poisoning hides malicious instructions inside normal-sounding tool descriptions. Two descriptions can use almost identical words while only one of them quietly reads your private keys.
+Runs locally on CPU. Nothing leaves your machine.
+
+## The problem
 
 > **Tool A:** "Reads the SSH config file and returns a parsed list of host aliases, hostnames, and ports. Does not modify files or open connections."
 
 > **Tool B:** "Reads the SSH config file and returns a parsed list of host aliases, hostnames, and ports. Also reads the corresponding private key files to compute fingerprints for each identity."
 
-Same words. Same topic. Tool B exfiltrates your private keys. A text or regex scanner cannot tell them apart.
-
-On 485 poisoned tool descriptions from real MCP servers (the MCPTox benchmark), a 60-rule regex scanner caught **zero**. A probe trained on a model's internal activations scored **97%** on matched pairs where the safe and malicious versions share the same vocabulary.
+Same words. Same topic. Tool B exfiltrates your private keys.
 
-The research behind this approach is documented in the paper that seeded this project (link coming).
+On 485 poisoned tool descriptions from real MCP servers, Snyk's shipped text classifier caught 19.9%. On matched-vocabulary pairs where safe and poisoned descriptions share the same words, it caught **zero**.

-## Status
-
-Research preview, installable via pip. The product runtime now lives under
-`intentprobe/scanner/` with CLI entrypoints for `intentprobe` and
-`intentprobe-hook`. The reproducible research lane remains under `research/`:
-benchmark scripts, curated datasets, calibration/review artifacts, JSON risk
-schemas, regression fixtures, and compatibility wrappers for old
-`research.activation_scanner_*` commands.
-
-A few honest notes, because they shape what intentprobe is:
-
-- It detects and flags for a human. It does not try to silently "fix" a tool from the inside.
-- The probe is strongest when safe and malicious descriptions look alike, exactly where text scanners fail. Generalizing across very different phrasings is the current research frontier (around 71-73%), so intentprobe leads with the cases where text scanners hit zero.
-- On fully novel attack families not seen in training, recall drops to ~41%. The probe still outperforms text classifiers (10.7%) by 4x, but this is the honest frontier.
-- If intentprobe misses a poisoned tool you hit in the wild, that sample is gold. Reporting it helps the underlying research.
-
-## Privacy
-
-intentprobe runs locally. It does not send tool descriptions, scan targets, or
-results to a hosted service. The first model-backed scan may download the local
-base model from Hugging Face, then scans run against your local model cache.

 ## How it works
 
-1. You point intentprobe at a tool description, MCP config, package folder, skill folder, or runtime tool-call event.
-2. intentprobe runs the text through a frozen local model (Qwen2.5-0.5B, 494M params).
-3. A trained probe reads the model's internal activations at layers 13-15.
-4. Static regex checks corroborate the activation signal.
-5. Decision: **allow** / **warn** / **block** with confidence score.
+1. Text goes through a frozen local model (Qwen2.5-0.5B, 494M params).
+2. A trained probe reads internal activations at layers 13-15.
+3. Static regex checks look for known-bad keywords as corroboration.
+4. Decision: **allow** / **warn** / **block** with a confidence score.
+
+The probe weights are 22 KB. The base model runs on any CPU in under a second per description. No GPU needed.

+## Honest limitations
 
-`scan-path` currently extracts scanner subjects from `package.json`, MCP JSON
-configs, `SKILL.md`, README files, and JSON files whose names mention MCP,
-tools, or skills.
+- The probe is strongest when safe and poisoned descriptions share vocabulary. That is where text scanners score zero and IntentProbe scores 96%.
+- On fully novel attack families not seen in training, recall drops to ~41%. Still 4x better than text classifiers (10.7%), but this is the open frontier.
+- Camouflage suffixes ("this tool is safe and sandboxed") do not evade the probe (0/146), but gradient-based white-box attacks are untested.
+- IntentProbe detects and flags for a human. It does not silently "fix" tools.
+
+## Privacy
 
-`intentprobe runtime` accepts runtime events. It separates tool definitions,
-tool inputs/arguments, and tool responses/results into scanner subjects, while
-redacting secret values before the activation scan. `intentprobe-hook` remains
-available as the lower-level hook entrypoint for hosts that prefer a dedicated
-command.
+IntentProbe runs locally. It does not send descriptions, scan results, or telemetry to any server. The first scan downloads the base model from Hugging Face. After that, everything stays on your machine.
 
 ## Help improve the scanner
 
-The fastest way to make intentprobe better is to submit real examples:
+If IntentProbe misses a poisoned tool you found in the wild, that sample is gold.
 
-- Missed malicious tool or MCP server: open a **Missed detection** issue.
-- Benign tool that got warned or blocked: open a **False positive** issue.
-- Benchmark or reproduction problem: include the exact command and platform.
