# claude-his-agent

A Claude Code subagent + skill for a personal home-infrastructure assistant
("His" — Home Infrastructure Specialist). Designed so a sibling Claude on any
host in your fleet can summon a single, consistent infra runbook instead of
re-learning your topology every session.

## Distribution model

This package ships **only the plumbing** — a fetcher and an installer. The
actual runbook (agent prompt + skill cheatsheet) lives on a private host that
you control and is pulled into a per-user cache the first time you run
`claude-his-install`. None of the infra context is in the public package or
its git history.

```
public package (this repo)         →   /usr/bin/claude-his-fetch
                                       /usr/bin/claude-his-install
                                       /usr/share/doc/claude-his-agent/README.md

private host (you set up)          →   /opt/his-context/agent.md
($HIS_CONTEXT_HOST, default hertz)     /opt/his-context/skill/SKILL.md
                                       /opt/his-context/scripts/...

per-user cache (after fetch)       →   ~/.cache/claude-his-agent/
~/.claude wiring (after install)   →   ~/.claude/agents/his.md   -> cache/agent.md
                                       ~/.claude/skills/his      -> cache/skill
```

`claude-his-fetch` is a thin `rsync -a -e ssh "$HOST:$PATH" "$CACHE/"`. The
trust boundary is your existing SSH key auth on `$HIS_CONTEXT_HOST`.

## Install

```bash
# Debian (trixie/bookworm):
sudo apt install claude-his-agent
claude-his-install

# Arch / ALARM:
sudo pacman -S claude-his-agent
claude-his-install
```

`claude-his-install` runs `claude-his-fetch` if the cache is empty, then
symlinks `~/.claude/agents/his.md` + `~/.claude/skills/his` to the cache.

## Refresh

Re-run `claude-his-fetch` whenever the runbook on the private host changes.
A weekly cron is reasonable:

```cron
0 4 * * 0  $HOME/.local/bin/claude-his-fetch >/dev/null 2>&1
```

(or just call `/usr/bin/claude-his-fetch` from any path the user can read.)

## Configuration

| Env var              | Default                              | Purpose |
|----------------------|--------------------------------------|---------|
| `HIS_CONTEXT_HOST`   | `hertz`                              | SSH target serving the context blob |
| `HIS_CONTEXT_PATH`   | `/opt/his-context/`                  | Source dir on the host (trailing slash) |
| `HIS_CONTEXT_CACHE`  | `~/.cache/claude-his-agent`          | Local cache dir |

`$HIS_CONTEXT_HOST` resolves through the user's `~/.ssh/config` and known_hosts,
so an alias like `Host hertz / HostName 192.0.2.10 / User youruser / IdentityFile ~/.ssh/id_ed25519`
keeps the rest of the stack hostname-agnostic.

## Setting up the private host

On `$HIS_CONTEXT_HOST`, lay out:

```
/opt/his-context/
├── agent.md            # subagent system prompt (the "take over" form)
├── skill/
│   └── SKILL.md        # skill cheatsheet (the "lookup" form)
└── scripts/            # any helpers the runbook references
    └── ...
```

Owner whichever account the fleet logs in as; mode `0644` for files, `0755`
for dirs. The directory does not need to be world-readable — `claude-his-fetch`
authenticates as the SSH user.

Bug reports / runbook gaps for the *private* runbook stay private; for the
public plumbing (fetcher, installer, build), file against this repo's issues.

Personal infra tooling; framework code is permissive (see LICENSE if shipped).
The runbook content (private) is not redistributable.
