Adds a final step to bootstrap.Init that offers to wire `veans prime`
into Claude Code and OpenCode automatically. Per-agent yes/no prompts
default to "yes" for Claude Code and "no" for OpenCode; --install-claude
/ --install-opencode flags skip the prompt for scripted contexts;
--no-hooks falls back to the previous behaviour of just printing the
snippets.
Claude Code:
- Writes/merges .claude/settings.json
- JSON merge preserves existing keys (model, permissions, other hooks)
and only appends a `veans prime` command entry under SessionStart
and PreCompact if one isn't already there
- Idempotent: re-running reports "Already configured" without
duplicating entries
OpenCode:
- Writes .opencode/plugin/veans-prime.ts with the standard handler
skeleton
- Existing files are left alone (no TS-merge story for v0)
Failures during hook install are non-fatal: the repo is already
configured, so the user gets a warning + the printed snippets as a
fallback path.
Unit tests cover the merge logic (fresh file, idempotent rerun,
preserving user's other hooks/keys), the install actions
("Wrote"/"Updated"/"Already configured"), and the offer flow
(flags-bypass-prompt vs prompt-when-unset vs no-hooks).
Vikunja's built-in OAuth server (Vikunja 2.3+) does not require client
registration and accepts arbitrary client_ids — it just enforces PKCE
(S256) and constrains redirect URIs to the vikunja- scheme. Earlier I
deferred OAuth on the assumption it needed a registered client; that
was wrong, and the docs make the path much smoother than POST /login.
The custom-scheme constraint (no http:// loopback) is side-stepped by
manual paste-back: veans prints the authorize URL, the user signs in,
their browser fails to open vikunja-veans-cli://callback?code=... and
shows an error, the user copies the URL from the address bar and
pastes it back. CLI extracts code + state, verifies state for CSRF,
exchanges via POST /api/v1/oauth/token (JSON body — Vikunja rejects
form-encoded), and returns the access token.
Resolution order in AcquireHumanToken:
1. --token (paste-in JWT or personal API token; SSO/OIDC users)
2. --use-password / --username + --password (POST /login)
3. OAuth flow (interactive default)
login command supports the same --use-password / --token escape hatches
for token rotation on instances with OAuth disabled.
Includes unit tests for the PKCE generator (verifier shape per RFC 7636,
challenge = SHA256(verifier) base64url-no-pad), authorize-URL
construction, and the lenient callback parser (full URL / query-only /
bare code).
