ci/woodpecker/pr/ci Pipeline was successful
fix(git): pr-review.sh — surface the provider's stated reason, drop the hardcoded #865 attribution (closes #1004)
All six HTTP-status error arms captured the provider's response body in a
mktemp file and then discarded it unread, so a caller got a status code and
no cause. The review-submit arm additionally hardcoded "(#865: no durable
review created)" onto EVERY non-2xx — including 401/403/404/409/422, where
the server had given a definite, correct, machine-readable refusal that is
categorically not #865 (the silent-no-op defect).

Measured case: `pr-review.sh -n 1001 -a approve` reported
  Error: Gitea review submit failed with HTTP 422 (#865: no durable review created)
when the real cause was that the acting credential authored the PR and Gitea
correctly refuses self-approval. Gitea said so plainly in the discarded body.

This matters beyond error aesthetics: withholding the cause pushes the caller
toward re-issuing the request by hand to see what the server says, and a
diagnostic that uses the real verb against the real object is not a
diagnostic, it is the operation.

Changes:
- New gitea_error_detail() renders the provider's own explanation (JSON
  message/error/errors, else the first body line), truncated to 300 chars.
  It always returns 0 so it can never abort a caller under `set -e`, and
  prints nothing when there is nothing to add.
- All six arms append it. The review-submit arm no longer cites #865; that
  reference now appears only on the check that actually diagnoses it — a 2xx
  yielding no id, immediately below.

No control flow changes: every arm still returns 1 and still fails closed.

Test hermeticity (required, or the new cases cannot run on any agent seat):
get_gitea_token()'s per-agent identity step reads `git config --get
mosaic.gitIdentity`, which on a provisioned seat is set GLOBALLY and leaks
into the harness's fresh `git init` repo. It then returns a REAL per-slot
token from $HOME without ever consulting MOSAIC_CREDENTIALS_FILE, so the
fixture placeholder was silently ignored and the suite ran against production
credentials, failing 401. The harness now pins an empty repo-local
mosaic.gitIdentity (an empty local value shadows the global and reads back
empty at rc=0) and runs under a sandboxed HOME. Filed separately: the
per-slot token store has no override hook, so no harness can sandbox it.

Verification matrix (all three run locally):
- base suite + hermeticity fix, unmodified wrapper -> PASS (fix is
  sufficient and breaks no existing case)
- new cases 19/20, unmodified wrapper -> FAIL at case 19, reproducing the
  exact misattribution above (negative control)
- new cases 19/20, fixed wrapper -> PASS

Cases 19 (422 JSON refusal) and 20 (502 HTML body) assert the status is
present, the provider's reason is present, and "#865: no durable review
created" is ABSENT. shellcheck is not installed on this host, so the lint
gate is unverified locally.

@mosaicstack/mosaic

CLI package for the Mosaic self-hosted AI agent platform.

Usage

mosaic wizard           # First-run setup wizard
mosaic gateway install  # Install the gateway daemon
mosaic config show      # View current configuration
mosaic config hooks list  # Manage Claude hooks

Headless / CI Installation

Set MOSAIC_ASSUME_YES=1 (or ensure stdin is not a TTY) to skip all interactive prompts. The following environment variables control the install:

Gateway configuration (mosaic gateway install)

Variable Default Required
MOSAIC_STORAGE_TIER local No
MOSAIC_GATEWAY_PORT 14242 No
MOSAIC_DATABASE_URL (none) Yes if tier=team
MOSAIC_VALKEY_URL (none) Yes if tier=team
MOSAIC_ANTHROPIC_API_KEY (none) No
MOSAIC_CORS_ORIGIN http://localhost:3000 No

Admin user bootstrap

Variable Default Required
MOSAIC_ADMIN_NAME (none) Yes (headless)
MOSAIC_ADMIN_EMAIL (none) Yes (headless)
MOSAIC_ADMIN_PASSWORD (none) Yes (headless)

MOSAIC_ADMIN_PASSWORD must be at least 8 characters. In headless mode a missing or too-short password causes a non-zero exit.

Example: Docker / CI install

export MOSAIC_ASSUME_YES=1
export MOSAIC_ADMIN_NAME="Admin"
export MOSAIC_ADMIN_EMAIL="[email protected]"
export MOSAIC_ADMIN_PASSWORD="securepass123"

mosaic gateway install

Runtime launchers

mosaic claude            # Launch Claude Code with Mosaic injection
mosaic yolo claude       # …with --dangerously-skip-permissions
mosaic codex | opencode | pi

mosaic claudex (EXPERIMENTAL)

Runs GPT models inside the Claude Code harness by pointing Claude Code at a local claude-code-proxy that translates the Anthropic Messages API to a ChatGPT-subscription (Codex OAuth) backend. This is not Anthropic Claude — model behavior, tool use, and output quality may differ. Intended for evaluation, not production delivery.

mosaic claudex           # launch (prompts through the proxy readiness gate)
mosaic yolo claudex      # …with --dangerously-skip-permissions
mosaic claudex --print "hello"   # trailing args are forwarded to Claude Code

Prerequisite: the claude-code-proxy binary must be installed and authenticated (claude-code-proxy codex auth …). mosaic claudex runs a preflight that verifies the binary, the OAuth state (triggering a device re-auth if needed), and a trusted local listener before launching; it fails closed if the proxy cannot be brought up with a verified identity.

Isolation (never touches your real Claude state). claudex always launches against an isolated CLAUDE_CONFIG_DIR (default ~/.config/mosaic/claudex/home). The ambient CLAUDE_CONFIG_DIR is deliberately ignored, and a guard proves the resolved dir can never be — or live under — the real ~/.claude. A claudex session therefore cannot mutate your normal Claude Code config.

No token leakage. claudex never reads the proxy's credential file. Claude Code is handed only ANTHROPIC_AUTH_TOKEN=unused pointed at the loopback proxy; the entire credential-bearing env family (ANTHROPIC_*, AWS_*, GOOGLE_CLOUD_*, GOOGLE_APPLICATION_CREDENTIALS, *_TOKEN, *_KEY, *_SECRET, …) is stripped from the composed environment. The Bedrock/Vertex routing switches (CLAUDE_CODE_USE_BEDROCK, CLAUDE_CODE_USE_VERTEX, and the _SKIP_*_AUTH pair) are force-removed regardless of value — otherwise their mere presence would route Claude Code to the real Anthropic API via AWS/GCP and bypass the proxy. The proxy holds the real OAuth credential.

Model tiers (override via env).

Tier Env var Default
primary (opus/sonnet) ANTHROPIC_MODEL gpt-5.6-sol
small/fast (haiku) ANTHROPIC_SMALL_FAST_MODEL gpt-5.6-luna

Operator-provided values win over the defaults. Additional overrides: MOSAIC_CLAUDEX_CONFIG_DIR (isolated config dir), ANTHROPIC_BASE_URL (proxy endpoint).

Hooks management

After running mosaic wizard, Claude hooks are installed in ~/.claude/hooks-config.json.

mosaic config hooks list              # Show all hooks and enabled/disabled status
mosaic config hooks disable PostToolUse  # Disable a hook (reversible)
mosaic config hooks enable PostToolUse   # Re-enable a disabled hook

Set CLAUDE_HOME to override the default ~/.claude directory.
