Add a Claude Code plugin: Kai hooks in shadow mode and the kai skill
examples/claude-code holds a Stop hook, a PreToolUse hook and the kai skill. .claude-plugin/marketplace.json makes this repo the marketplace "kai" (not "hanzo", a name another Hanzo marketplace already holds), so /plugin install kai@kai installs it. Kai does not yet read agent work reliably: its zero-shot answers to "done", "verified" and "risky" are near chance. So rules in code decide first, Kai can only tighten (send a turn back, or ask before an action; never allow), both hooks fail open on any error or timeout, and the default mode, shadow, logs Kai's answers and changes nothing. The log holds probabilities and verdicts only, 0600 in a 0700 directory. A state sent to Kai is redacted and at most 3,000 characters of JSON; only https, or http on loopback, is called, and no redirect is followed. Against the first draft: plugin options are read as CLAUDE_PLUGIN_OPTION_<KEY> uppercased, as Claude Code exports them (the draft read lowercase names and never saw the plugin's key or mode). The floor is checked before the read-only shortcut, which let "env rm -rf" and awk's system() through, and now catches "git checkout -- .", "rm -Rf" and split rm flags. A background-task notice no longer starts a new turn. Stop answers with decision "block" as JSON. Only the last 8 MiB of a transcript is read: a 745 MB one made the hook throw. test/kai.test.mjs runs both hooks offline against a stand-in for Kai on 127.0.0.1, 25 tests; test.sh runs it with the rest. In a live Claude Code 2.1.296 session against the stand-in, the Stop block came back as "Stop hook feedback", the PreToolUse ask denied an allowed command under -p, and shadow showed a notice and let it run.

## Claude Code plugin
|
||||
|
||||
[`examples/claude-code`](./examples/claude-code/) is a Claude Code plugin: a `Stop`
|
||||
hook, a `PreToolUse` hook, and the `kai` skill
|
||||
([`SKILL.md`](./examples/claude-code/skills/kai/SKILL.md): when and how an agent should
|
||||
ask Kai). It needs Claude Code 2.1.271 or later and `node` on the `PATH` (tested with
|
||||
Node.js 24).
|
||||
|
||||
**Kai does not yet judge agent work reliably.** Its zero-shot answers to "is this
|
||||
done", "is this verified" and "is this action risky" are near chance: on a set of 20
|
||||
agent stops its "done" answer was right 8 times where a fixed rule table was right
|
||||
16, it scored read-only calls as writes, and it read successful tool results as
|
||||
failures. Recipes 03, 04 and 05 above, which ask such questions, fail too. So the
|
||||
plugin is built to collect evidence, not to improve stops:
|
||||
|
||||
- Rules in code decide first. Kai is asked only where they leave the question open.
|
||||
- Kai can only tighten: send a turn back, or ask you before an action. Neither hook
|
||||
allows anything, and your own permission rules still apply.
|
||||
- The default mode, `shadow`, asks Kai, logs its answers, shows a one-line notice of
|
||||
what the hook would have done, and changes nothing.
|
||||
|
||||
Do not switch to `on` expecting better stops until a Kai version trained for these
|
||||
questions ships.
|
||||
|
||||
What each hook does in `on`:
|
||||
|
||||
- **Stop.** When the turn changed files and no test, build or lint passed after the
|
||||
last change (read from the transcript), Kai is asked whether the closing message
|
||||
reports the work done, whether a check verified it, and whether a check would be a
|
||||
meaningful way to verify it. Done at 0.70 or more, verified under 0.50 and a check
|
||||
applying at 0.50 or more send the turn back once to run a check, at most three
|
||||
times a session.
|
||||
- **PreToolUse.** For shell commands, and for writes outside the project or to
|
||||
`.env`, keys and credential directories: a fixed list (`rm -rf`, force push,
|
||||
`git reset --hard`, `git checkout -- .`, `git clean -f`, `DROP TABLE`,
|
||||
`terraform destroy`, `curl … | sh`, and a few more in `hooks/kai.mjs`) asks you to
|
||||
confirm whatever Kai says. Kai is asked whether the action is irreversible or
|
||||
reaches beyond this machine; either answer at 0.90 or more asks too. Commands that
|
||||
only read or run the project's checks, and writes inside the project, never call
|
||||
Kai.
|
||||
|
||||
Both hooks fail open: no key, an error, a timeout (8 s for `Stop`, 1.5 s for
|
||||
`PreToolUse`) or an event they do not read leaves Claude Code as it is without them.
|
||||
|
||||
Install:
|
||||
|
||||
```text
|
||||
/plugin marketplace add hanzoai/kai
|
||||
/plugin install kai@kai
|
||||
```
|
||||
|
||||
Claude Code asks for the API key, which it keeps in secure storage, and the mode.
|
||||
Leave the key empty to use `HANZO_API_KEY` from the environment Claude Code starts
|
||||
in. `KAI_HOOK_MODE=shadow|on|off` in that environment overrides the mode.
|
||||
|
||||
**What is sent.** Only to `https://api.hanzo.ai/v1/decisions` (or `KAI_URL`, which
|
||||
must be https, or http on loopback), in a state of at most 3,000 characters, with
|
||||
tokens, keys and passwords of common shapes and the key in use redacted. `Stop`
|
||||
sends your last prompt, the closing message, up to five changed file paths, and the
|
||||
last two checks' commands and the ends of their output. `PreToolUse` sends the
|
||||
command or file path, the working directory and the permission mode.
|
||||
|
||||
**What is logged.** `~/.hanzo/kai-hook/decisions.jsonl` (directory 0700, file 0600), a
|
||||
line for each Kai call: time, hook, a hash of the session id, mode, tool name, model,
|
||||
the probabilities, the verdict (`send`, or `floor` and `hold`), milliseconds, or the
|
||||
error.
|
||||
Never prompt, command or file text, never the key. To read it:
|
||||
|
||||
```bash
|
||||
# Each stop Kai was asked about, and whether it sent (or in shadow would have sent) it back
|
||||
jq -c 'select(.hook == "stop") | {at, mode, answers, send}' ~/.hanzo/kai-hook/decisions.jsonl
|
||||
# Gate calls by verdict
|
||||
jq -s 'map(select(.hook == "gate")) | group_by(.hold) | map({hold: .[0].hold, calls: length})' ~/.hanzo/kai-hook/decisions.jsonl
|
||||
```
|
||||
|
||||
Uninstall:
|
||||
|
||||
```text
|
||||
/plugin uninstall kai@kai
|
||||
/plugin marketplace remove kai
|
||||
```
|
||||
|
||||
then `rm -rf ~/.hanzo/kai-hook`.
|
||||
|
||||
`node --test examples/claude-code/test/kai.test.mjs` runs the hooks against a stand-in
|
||||
for Kai on 127.0.0.1, with no network and no key; `test.sh` runs it too.

Ask Kai, Hanzo's decision model, for a typed answer when the next step is a
|
||||
decision among answers known in advance: pick one of a set of options, rate
|
||||
on an ordered scale, or give the probability that a statement about a state
|
||||
holds. Use it to route, triage or classify, and batch every question about
|
||||
one state into one call. Do not use it to write text or code, for arithmetic
|
||||
or exact lookups, for anything a fixed rule decides, as permission to act,
|
||||
or to judge whether agent work is done, verified or safe.
|
||||
metadata:
|
||||
short-description: Typed decisions from Kai at api.hanzo.ai

|

|
||||
# Kai
|
||||
|
||||
Kai answers typed questions about a state with probabilities. It writes no
|
||||
text. You stay the planner and the writer; code you own maps Kai's answer to
|
||||
an action.
|
||||
|
||||
## Setup
|
||||
|
||||
Kai needs one variable, set outside the conversation:
|
||||
|
||||
```text
|
||||
HANZO_API_KEY a Hanzo API key (never paste it here)
|
||||
KAI_URL optional; default https://api.hanzo.ai/v1/decisions
|
||||
KAI_MODEL optional; default kai
|
||||
```
|
||||
|
||||
If `HANZO_API_KEY` is missing, say so and stop. Do not search files, shell
|
||||
history or the environment of other programs for a key. Never print, log or
|
||||
commit the key.
|
||||
|
||||
## When to ask Kai
|
||||
|
||||
Ask when the answer space is known before the call and the answer changes
|
||||
what happens next:
|
||||
|
||||
- which of these options (a queue, a team, a retrieval path, a model tier);
|
||||
- how much, on an ordered scale (urgency, severity);
|
||||
- whether a statement about the state holds.
|
||||
|
||||
Do not ask when you already know the answer, when a rule decides it, or when
|
||||
the answer is text you must write.
|
||||
|
||||
## What Kai does not judge reliably yet
|
||||
|
||||
Kai's current version does not read agent work reliably: whether a task is
|
||||
done, whether a change is verified, whether a command is risky. The
|
||||
cookbook's command-risk, progress and completion recipes (03, 04, 05) fail on
|
||||
it. Decide those with rules in code (did a test, build or lint pass after the
|
||||
last edit; does the command match a known destructive pattern) and with the
|
||||
user's permission prompts. If you ask Kai anyway, keep its answer as a logged
|
||||
signal and do not act on it.
|
||||
|
||||
## Keep the facts next to the call
|
||||
|
||||
| Facts | Do |
|
||||
| --- | --- |
|
||||
| Already in your context | One call, every question about that state batched in it |
|
||||
| In a file or a tool's output | A script reads them and sends them to Kai; the items never enter your context |
|
||||
| Not yet known | Gather the evidence first; then one call |
|
||||
|
||||
Do not paste bulk data into a call by hand.
|
||||
|
||||
## The call
|
||||
|
||||
```bash
|
||||

```
|
||||
|
||||
`state` is text, an object or an array. Name its fields and refer to them in
|
||||
backticks in the questions. Unknown fields are refused: 400 at the top level,
|
||||
422 inside a question.
|
||||
|
||||
Question types:
|
||||
|
||||
- `choice`: `criteria` maps each option to what it means, or lists the
|
||||
options; at least two. The answer has `choice`, `probabilities` over every
|
||||
option, `answer_confidence` (the probability of the pick) and `confidence`
|
||||
(`(p − 1/n) / (1 − 1/n)`, which reads 0 for an even spread over any n).
|
||||
- `score`: `criteria` lists the levels, lowest first. The answer has `score`
|
||||
(the expected level index), `legend`, `probabilities` per level,
|
||||
`answer_confidence` and `confidence`.
|
||||
- `noul`: `instructions` is a yes/no question. The answer is
|
||||
`{"type": "noul", "noul": p}`, p the probability of yes. There is no separate
|
||||
confidence: certainty is the distance of p from 0.5.
|
||||
|
||||
At most 100 questions a call. Kai reads each question with up to 1,024 tokens
|
||||
of state, the length it was trained at; a longer state is answered with
|
||||
`routing.extrapolated: true`, and those answers are not reliable. Keep the
|
||||
state to the facts the questions need.
|
||||
|
||||
## Reading answers
|
||||
|
||||
- Threshold on `noul` or on `answer_confidence`, never on `confidence`: one
|
||||
`confidence` value means different things at 2 and at 200 options.
|
||||
- Choose thresholds from the cost of each mistake and from labelled examples
|
||||
of your own traffic. There is no universal threshold.
|
||||
- Below your threshold the decision is yours again: decide it yourself, gather
|
||||
more evidence, or ask the user.
|
||||
- Kai's answer is a signal. It never grants permission, never runs the action
|
||||
it judged, and never replaces a deterministic check or a human approval.
|
||||
|
||||
## Asking well
|
||||
|
||||
- Put the deployment in the state ("a reader assistant for a news site"), not
|
||||
only the item.
|
||||
- Write options that describe the situation ("the request needs today's
|
||||
prices") rather than abstract classes ("live").
|
||||
- One judgment per question. No "and", no counting, no date arithmetic.
|
||||
- Add an `other` or `unknown` option when the listed ones may not cover the
|
||||
case.
|
||||
- For many candidates (files, tools, documents), ask one `choice` with the
|
||||
candidates as options, not one `noul` per candidate.
|
||||
|
||||
## Failures
|
||||
|
||||
The body of an error is `{"error": {"code", "message"}}`.
|
||||
|
||||
- `400` or `422`: the request is malformed or too long, and the message says
|
||||
which. Fix or shrink it; do not retry unchanged.
|
||||
- `429` or `529`: wait `retry-after-ms` (else `Retry-After`), retry once.
|
||||
- `401`: the key is missing or wrong; tell the user.
|
||||
- Anything else, or a timeout: proceed as if Kai did not exist.
|
||||
|
||||
Never repeat a consequential action because a decision call failed.
|
||||
|
||||
## Audit
|
||||
|
||||
When a workflow needs a record, keep the question definitions, the model id
|
||||
Kai answered with (`model` in the reply), the probabilities, and the action
|
||||
taken. Never the key.
