# Tobserver Change
|
||||||
|
|
||||||
|
Use the trusted `tobserver-agent` command, packaged from [`scripts/tobserver-agent`](scripts/tobserver-agent), to create isolated workspaces, run policy checks, and submit tokenless Forgejo AGit pull requests. The protected repository and human web merge are the approval boundary; the live server is outside the agent's reach.
|
||||||
|
|
||||||
|
## Required setup
|
||||||
|
|
||||||
|
- Before first use or after an authentication/policy failure, read [`references/setup.md`](references/setup.md). It defines the required Codeberg branch protection, personal SSH identity, installation, verification, and bot-retirement sequence.
|
||||||
|
- Work only in a workspace created or validated by `tobserver-agent`.
|
||||||
|
- Use only `https://codeberg.org/oibot/Tobserver.git` for fetches and `ssh://git@codeberg.org/oibot/Tobserver.git` for AGit submission.
|
||||||
|
- Never use a Codeberg API token, authenticated browser session, raw push command, or pull-request write API. The helper uses SSH AGit and public read-only API requests.
|
||||||
|
|
||||||
|
## Non-negotiable boundary
|
||||||
|
|
||||||
|
- Keep work on local `agent/*` branches and helper-managed `tobserver-agent-*` AGit topics.
|
||||||
|
- Never push to, force-push, delete, or merge `main` or any remote branch.
|
||||||
|
- Never approve or merge the pull request; the user does that in Codeberg's web UI.
|
||||||
|
- Never SSH to Tobserver, copy files to it, run remote commands, deploy, or run `nixos-rebuild` against it.
|
||||||
|
- Never request or use the server's SOPS age private key, decrypt SOPS files, expose plaintext secrets, or modify encrypted payloads.
|
||||||
|
- Never bypass a failed helper check. Preserve failed or interrupted workspaces for recovery.
|
||||||
|
|
||||||
|
If the helper is unavailable, the setup is unconfirmed, or the workspace is rejected, stop and report the missing prerequisite. Do not reproduce its privileged behavior ad hoc.
|
||||||
|
|
||||||
|
## 1. Establish the workspace
|
||||||
|
|
||||||
|
Run `tobserver-agent status`. If no valid active workspace exists:
|
||||||
|
|
||||||
|
- New change: `tobserver-agent start "<short task description>"`
|
||||||
|
- Existing PR correction: `tobserver-agent revise <PR_NUMBER>`
|
||||||
|
- Explicit interrupted work: `tobserver-agent resume /tmp/tobserver-agent.XXXXXX`
|
||||||
|
|
||||||
|
For revisions, accept only an open AGit PR in `oibot/Tobserver` targeting `main`, opened by `oibot`, with a helper-managed topic and `refs/pull/<number>/head`. Inspect the PR, discussion, diff, relevant modules, flake outputs, and recent commits before editing.
|
||||||
|
|
||||||
|
Respect “plan only” or “do not push.” Investigate without submission; create a workspace only when useful and preserve it.
|
||||||
|
|
||||||
|
## 2. Make the smallest declarative change
|
||||||
|
|
||||||
|
1. Explain the files and behavior to change, safe macOS checks, and human-only follow-up.
|
||||||
|
2. Prefer focused changes to existing modules. Avoid unrelated refactors and `flake.lock` churn.
|
||||||
|
3. Separate secret wiring from human secret provisioning. Do not edit `secrets/` or `.sops.yaml`.
|
||||||
|
4. Do not run Linux builds, deployment tools, or commands that instantiate and execute a Tobserver system closure.
|
||||||
|
|
||||||
|
## 3. Check and review
|
||||||
|
|
||||||
|
Run `tobserver-agent check`. It enforces Nix formatting, Git whitespace, `nix flake check --no-build`, Tobserver derivation evaluation, secret-path policy, and Gitleaks.
|
||||||
|
|
||||||
|
Fix relevant failures and rerun. If a platform or external constraint blocks a check, report the exact failure and workspace path; do not submit.
|
||||||
|
|
||||||
|
Inspect the final diff for credentials, decrypted values, private keys, unrelated edits, generated result links, and accidental lock-file changes.
|
||||||
|
|
||||||
|
## 4. Submit for human review
|
||||||
|
|
||||||
|
Before submission, read and instantiate [`assets/pull-request-body.md`](assets/pull-request-body.md). Report the workspace, branch/topic, diff summary, checks, risks, and manual steps.
|
||||||
|
|
||||||
|
Unless the user explicitly requested no submission, run:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
tobserver-agent submit --title "<concise commit title>" --body-file <body-file>
|
||||||
|
```
|
||||||
|
|
||||||
|
The helper commits the change, pushes only to `refs/for/main/<topic>`, creates or linearly updates one PR, verifies its public metadata, and cleans the workspace only after success.
|
||||||
|
|
||||||
|
Report the PR URL and ask the user to review and merge it in Codeberg. Deployment remains manual after merge.
|
||||||
|
|
||||||
|
## Recovery
|
||||||
|
|
||||||
|
- Preserve workspaces after failed checks, interrupted work, ambiguous behavior, or failed submission.
|
||||||
|
- Resume with `tobserver-agent resume <workspace>`.
|
||||||
|
- Run `tobserver-agent cleanup <workspace>` only when the user explicitly requests cleanup after understanding unsubmitted work will be deleted.
|
||||||
|
|
||||||
|
## Maintenance
|
||||||
|
|
||||||
|
When changing the bundled helper, run:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
bash -n scripts/tobserver-agent
|
||||||
|
scripts/tobserver-agent --help
|
||||||
|
tests/tobserver-agent-test
|
||||||
|
```
|
||||||
|
|
||||||
|
Then run one representative safe workspace check without submitting or accessing the live server.

# Tobserver Agent Setup
|
||||||
|
|
||||||
|
Use this reference before first use and whenever SSH authentication, branch protection, AGit submission, or helper installation changes.
|
||||||
|
|
||||||
|
## Security model
|
||||||
|
|
||||||
|
The same Codeberg account, `oibot`, creates AGit pull requests and later performs a human web merge. Safety therefore depends on two separate capabilities:
|
||||||
|
|
||||||
|
- SSH may submit AGit changes but protected `main` rejects direct, force, and deletion pushes.
|
||||||
|
- The agent has no write-capable Codeberg API token or authenticated browser session. Only the human web session merges or changes repository settings.
|
||||||
|
|
||||||
|
This model does not provide separate agent attribution or independently enforceable approval by another account.
|
||||||
|
|
||||||
|
## Protect `main`
|
||||||
|
|
||||||
|
In `oibot/Tobserver` → **Settings** → **Branches**, create an exact rule for `main` that:
|
||||||
|
|
||||||
|
- forbids direct pushes for everyone, including `oibot` and repository owners;
|
||||||
|
- has no user, team, deploy-key, or administrator push bypass;
|
||||||
|
- forbids force pushes and branch deletion;
|
||||||
|
- requires pull-request merging;
|
||||||
|
- retains required checks and conversation resolution when configured.
|
||||||
|
|
||||||
|
Inspect the saved rule in the UI. Do not test protection by making a potentially successful push to Tobserver `main`; use a disposable repository for a push-level test.
|
||||||
|
|
||||||
|
## Configure the personal SSH identity
|
||||||
|
|
||||||
|
Normal Codeberg remotes must select the personal key explicitly even if another key is loaded:
|
||||||
|
|
||||||
|
```sshconfig
|
||||||
|
Host codeberg.org
|
||||||
|
HostName codeberg.org
|
||||||
|
User git
|
||||||
|
IdentityFile ~/.ssh/id_ed25519
|
||||||
|
IdentitiesOnly yes
|
||||||
|
```
|
||||||
|
|
||||||
|
Verify without pushing:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
ssh -T git@codeberg.org
|
||||||
|
```
|
||||||
|
|
||||||
|
Expected identity: `oibot`.
|
||||||
|
|
||||||
|
## Install from the Agent Skills catalog
|
||||||
|
|
||||||
|
Pin `https://codeberg.org/oibot/agent-skills.git` as a non-flake Nix input. Load `create-skill` and `tobserver-change` from that pinned source.
|
||||||
|
|
||||||
|
Expose the helper on `PATH` by packaging the canonical bundled file `tobserver-change/scripts/tobserver-agent`; do not keep a second editable helper copy in dotfiles. Provide these runtime commands:
|
||||||
|
|
||||||
|
- Bash
|
||||||
|
- Git and OpenSSH
|
||||||
|
- curl
|
||||||
|
- jq
|
||||||
|
- Nix
|
||||||
|
- nixpkgs-fmt
|
||||||
|
- Gitleaks
|
||||||
|
- standard core utilities including `base64`
|
||||||
|
|
||||||
|
Run after installation:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
tobserver-agent --help
|
||||||
|
```
|
||||||
|
|
||||||
|
## Confirm tokenless operation
|
||||||
|
|
||||||
|
The helper may perform unauthenticated `GET` requests to the public API under:
|
||||||
|
|
||||||
|
```text
|
||||||
|
https://codeberg.org/api/v1/repos/oibot/Tobserver
|
||||||
|
```
|
||||||
|
|
||||||
|
It must not read a Keychain Codeberg token, send an authorization header, call a write API, approve, or merge.
|
||||||
|
|
||||||
|
AGit submissions use only:
|
||||||
|
|
||||||
|
```text
|
||||||
|
ssh://git@codeberg.org/oibot/Tobserver.git
|
||||||
|
HEAD:refs/for/main/tobserver-agent-<unique-topic>
|
||||||
|
```
|
||||||
|
|
||||||
|
## Retire `oibot-agent`
|
||||||
|
|
||||||
|
Retire old credentials only after the catalog-backed helper successfully creates and linearly revises one unmerged test PR:
|
||||||
|
|
||||||
|
1. Confirm no open PR or active workspace still depends on `oibot-agent`.
|
||||||
|
2. Remove the `codeberg-tobserver-agent` SSH alias.
|
||||||
|
3. Unload the bot key with `ssh-add -d ~/.ssh/oibot-agent`.
|
||||||
|
4. Revoke the bot API token and remove its macOS Keychain entry.
|
||||||
|
5. Remove the bot SSH key and repository access in Codeberg.
|
||||||
|
6. Archive or delete the account only after confirming it owns no required repository or audit artifact.
|
||||||
|
7. Delete local bot key files only after explicit confirmation and any desired backup.
|
||||||
|
|
||||||
|
Do not rewrite historical commits or PRs to erase the old account name.
|
||||||
|
|
||||||
|
## Recovery
|
||||||
|
|
||||||
|
Until the new workflow passes end to end, keep old credentials available but do not load the bot key globally. If cutover fails, restore the previous pinned skill revision; never weaken `main` protection as a rollback shortcut.
