# agent-tools

Two small Gitea-automation CLIs, shipped together in one RPM (`agent-tools`).
Both act as the **`unkin-agent`** user by minting a scoped Gitea token from
Vault, so automated PRs and comments are attributed to the agent — not to
whoever happens to run the command.

- **`agentpr`** — create pull requests and post PR comments as `unkin-agent`.
- **`watchpr`** — poll one or more PRs and exit when one changes in a way worth
  acting on.

## How it gets a token

On first use each tool performs a Vault AppRole login (`role_id` only, no
`secret_id`), then reads `gitea/creds/unkin-agent` to obtain a short-lived Gitea
token, cached in-process for the run.

Everything is configured by environment variables, all with defaults:

| Variable | Default | Purpose |
|---|---|---|
| `VAULT_ADDR` | `https://vault.service.consul:8200` | Vault/OpenBao address |
| `AGENT_APPROLE_ROLE_ID` | `ababbcd3-9c77-5c6a-be2d-287fce9214a6` | AppRole role_id |
| `GITEA_URL` | `https://git.unkin.net` | Gitea base URL |
| `AGENT_LOGIN` | `unkin-agent` | login whose comments `watchpr` ignores |

## agentpr

```bash
# Verify identity (should print: unkin-agent)
agentpr whoami

# Open a PR
agentpr pr create --repo unkin/argocd-apps \
  --base main --head benvin/my-change \
  --title "Add woodpecker SA" --body "Adds the ServiceAccount ..."
# prints: #<number> <html_url>

# Comment on a PR
agentpr pr comment --repo unkin/argocd-apps --pr 42 --body "Rebased, CI green."

agentpr --version
agentpr --help
```

Non-zero exit on any API error.

## watchpr

Poll PRs and exit (reporting what changed) when a tracked PR **merges/closes**,
gets a **new comment from someone other than the agent**, its **CI fails**
(failure/error), or it **loses mergeability** (a conflict appears). Benign
transitions — CI `pending`→`success`, the agent's own comments — are ignored.

```bash
# Watch until something meaningful happens (default interval 60s)
watchpr unkin/argocd-apps#42

# Multiple PRs, custom interval; refs accept #N or :N
watchpr --interval 30s unkin/argocd-apps#42 unkin/terraform-vault:98

# One-shot: print current state and exit 0 (great for scripts)
watchpr --once unkin/argocd-apps#42
watchpr --once --json unkin/argocd-apps#42
```

On a meaningful change `watchpr` prints the reason and the PR's current state,
then exits 0. Use `--json` for machine-readable output.

## Build & package

```bash
make build                 # -> dist/agentpr, dist/watchpr
make test                  # go test -race ./...
make rpm                   # build + package dist/agent-tools-<version>-1.x86_64.rpm
```

Release is tag-driven (`v*`) via Woodpecker: builds the RPM, `PUT`s it to the
artifactapi `rpm-internal` yum repo, and cuts a Gitea release with
cross-compiled binaries attached.

### Version bump

```bash
make patch   # or: make minor / make major  — tags vX.Y.Z and pushes the tag
```
