Enhance UX across CLI and cloud providers with actionable error messages:
1. Modal sandbox creation failures now provide:
- Detailed error output from Python SDK
- Common causes (auth expired, quota issues, network)
- Step-by-step troubleshooting (re-auth, check quota, status page)
2. Modal CLI installation failures now explain:
- Missing pip/pip3 (with installation commands)
- Permission issues (suggest --user flag)
- Manual installation steps
3. Sprite connectivity failures now include:
- Commands to check sprite status and logs
- Steps to recreate sprite
- Support contact information
4. Sprite CLI installation now:
- Catches installation failures with helpful error messages
- Verifies installation succeeded before proceeding
- Provides manual installation instructions
5. CLI script download failures improved:
- Distinguish between 404 (doesn't exist) and other errors
- Provide specific next steps for each scenario
- Suggest checking matrix for implementation status
All error messages follow the pattern:
- What went wrong
- Why it might have happened (common causes)
- What to do next (actionable steps)

* ux: Improve error messages and user guidance across CLI and shell scripts
Enhanced error messages to be more actionable and user-friendly:
CLI improvements (commands.ts):
- Made validateNonEmptyString clearer: "is required but was not provided"
- Reordered troubleshooting steps to check matrix first (most common issue)
- Simplified 404 error message: "doesn't exist yet" vs "may not be implemented"
- Changed "Troubleshooting steps" to just "Troubleshooting" (less formal)
Shared library improvements (shared/common.sh):
- OAuth cancellation now explains why API key is needed and where to get it
- safe_read non-TTY error explains what non-interactive mode is with example
- get_resource_name error shows exact env var syntax needed
- Agent verification failures now list specific possible causes
- All improvements add context and next steps rather than just stating the problem
Hetzner library improvements (hetzner/lib/common.sh):
- Replaced technical "Remediation" with friendly "How to fix"
- Changed log_warn to log_error for error conditions (consistent severity)
- Added spacing for better readability of multi-line errors
- Made server creation errors more specific about account issues
All changes focus on helping users understand WHAT went wrong and HOW to fix it.

* feat: Replace issue-triager with community-coordinator agent
Replace the issue-triager agent in the refactor team with a
community-coordinator that actively engages with GitHub issues:
acknowledges reports, posts interim updates, delegates to relevant
teammates, and posts final resolutions — so reporters feel heard.

Fixes#59
The instanceof operator can fail in bundled/minified code or when
errors cross execution realm boundaries, causing the error:
"instanceof called on an object with an invalid prototype property"
This commit replaces all instanceof Error checks with duck typing
(checking for object with 'message' property) which is more reliable
across different execution contexts.
Changes:
- index.ts: Updated handleError() and prompt file error handling
- commands.ts: Updated getErrorMessage() helper

Security:
- Fix command injection in modal/lib/common.sh (run_server, upload_file, interactive_session)
- Fix command injection in fly/lib/common.sh (run_server, upload_file, interactive_session)
- All container providers now use printf '%q' for proper shell escaping
Complexity:
- Extract _api_should_retry_on_error() helper in shared/common.sh (-19 lines)
- Refactor scaleway_api and upcloud_api to use shared retry helper (-24 lines)
- Extract _save_fly_token() helper in fly/lib/common.sh (-11 lines)
- Extract validateAndGetAgent() in commands.ts, reducing cmdRun/cmdAgentInfo duplication
- Refactor cmdList column width calculation to use calculateColumnWidth()
UX:
- Add actionable next steps to error messages in shared/common.sh
- Improve CLI bash fallback error messages with guidance (spawn.sh)
- Add OAuth progress indicator during browser authentication wait
- Show invalid model ID value and link to openrouter.ai/models
- Add troubleshooting steps for agent installation failures
Tests:
- Update test assertions in test/run.sh to match refactored patterns
- All tests passing: 74 TypeScript + 75 bash = 149 total, 0 failures

~/.bun/bin is often NOT in PATH, causing 'command not found' after
install. Now picks the first dir already in PATH from:
1. ~/.local/bin (most universal)
2. $(bun pm bin -g)
3. ~/.bun/bin
4. ~/bin
Also consolidated PATH detection and instructions into shared helpers,
with clear shell-specific instructions when the dir isn't in PATH.

bun link only registers packages for project-level linking — it does
not create global CLI binaries. bun install -g has the same issue.
New approach:
- bun: build cli.js, copy directly to $(bun pm bin -g)/spawn (55KB)
- npm: build with esbuild, copy to $(npm bin -g)/spawn
- Both methods put the binary exactly where the runtime expects it
Also replaced brittle hardcoded file downloads with git sparse-checkout
(with GitHub API fallback), so new source files never break the installer.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The install script had a hardcoded list of source files to download,
which broke whenever a new file was added (e.g., security.ts). Also,
openrouter.ai/lab/spawn served a stale cached version without the fix.
Now uses git sparse-checkout (fast, gets only cli/) with a GitHub API
fallback for environments without git. Adding new source files will
never break the installer again.

commands.ts imports ./security.js but install.sh never downloaded
security.ts, causing build to fail with "Could not resolve" error.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
package.json bin points to cli.js, but it was never built during
installation. Both bun link and npm install -g failed silently because
the file didn't exist.
- Bun path: run `bun run build` before `bun link`
- npm path: use npx esbuild to bundle cli.js with node shebang

Enhance the spawn CLI user experience with actionable error messages,
comprehensive help documentation, and visual progress feedback.
Changes:
- Help text: Add AUTHENTICATION, TROUBLESHOOTING, and MORE INFO sections
- Error messages: Show examples of valid options when validation fails
- Progress indicators: Add spinners for script downloads
- Install flow: Provide clear alternatives when npm install requires sudo
- README: Add environment variable documentation and alternative install URL
- Security errors: Suggest workarounds for false positives
All error messages now follow the pattern:
1. What went wrong
2. Why it matters
3. What to do next

* refactor: extract shared test helpers and utilities
Created centralized test-helpers.ts module to eliminate duplication across test files:
**Extracted Helpers:**
- createMockManifest() - Reusable mock manifest data
- createEmptyManifest() - Empty manifest for edge cases
- createConsoleMocks() - Console spy setup
- createProcessExitMock() - Process exit mock
- restoreMocks() - Mock cleanup utility
- mockSuccessfulFetch() - Simplified successful fetch mock
- mockFailedFetch() - Simplified failed fetch mock
- mockFetchWithStatus() - Fetch mock with custom status
- setupTestEnvironment() - Test directory and env setup
- teardownTestEnvironment() - Cleanup utility
**Deduplication Impact:**
- commands.test.ts: Removed 50+ lines of duplicate mock setup
- manifest.test.ts: Removed 80+ lines of duplicate manifest data and setup code
- integration.test.ts: Removed 40+ lines of duplicate setup/teardown
**Benefits:**
- Single source of truth for test fixtures
- Consistent mock patterns across all tests
- Easier maintenance - changes to test setup in one place
- Improved test readability

* refactor: Add non-interactive mode for agent execution
Implements --prompt and --prompt-file flags to enable non-interactive
agent execution. This allows users to:
- Execute agents with a prompt and exit automatically
- Use spawn in CI/CD pipelines and automation scripts
- Pass prompts via command line or file
Changes:
- TypeScript CLI: Parse --prompt/-p and --prompt-file flags
- Security: Add validatePrompt() to prevent command injection
- Commands: Pass prompt via SPAWN_PROMPT env var to bash scripts
- Bash scripts: Detect SPAWN_PROMPT and fork interactive/non-interactive
- Help text: Document new flags with examples
Implementation:
- claude.sh: Use 'claude -p' for non-interactive execution
- aider.sh: Use 'aider -m' for non-interactive execution
- shared/common.sh: Add execute_agent_non_interactive() helper
Security:
- Validates prompts for command injection patterns
- Length limit: 10KB max
- Blocks $(), backticks, piping to bash/sh
- Uses printf %q for proper shell escaping

Added back `mock`, `join`, `tmpdir`, `mkdirSync`, and `rmSync` imports
that were accidentally removed during test deduplication refactoring.
Tests now pass (39 pass, 11 skip, 1 fail - same pre-existing failure).

- Remove vitest and @vitest/ui from devDependencies
- Update test scripts to use 'bun test'
- Delete vitest.config.ts (no longer needed)

- Update CLAUDE.md to prohibit vitest, mandate bun:test
- Replace vi.fn() with mock() from bun:test
- Replace vi.spyOn with spyOn from bun:test
- Note: commands.test.ts needs module mocking refactor (TODO)

Added EXIT traps to ensure temporary files are cleaned up even if scripts crash or are interrupted:
**cli/spawn.sh** (2 mktemp calls):
- Line 219: Added trap after mktemp in fetch_manifest(), clear trap after mv
- Line 537: Added trap after mktemp in cmd_update(), clear trap after mv
- Removed manual rm -f calls in error paths (trap handles cleanup)
**sprite/lib/common.sh** (3 mktemp calls):
- setup_shell_environment(): Consolidated trap for both path_temp and bash_temp
- inject_env_vars_sprite(): Added trap for env_temp, clear after successful upload
**shared/common.sh** (cleanup system):
- Auto-register cleanup trap at end of file when sourced
- This activates the existing track_temp_file() + cleanup_temp_files() system
- Previously register_cleanup_trap() had to be manually called (only 1 script did this)
Impact: Prevents /tmp file leaks when scripts are killed, crashed, or interrupted mid-execution.

- Add --max-time 30 to OAuth key exchange curl to prevent indefinite hangs
- Remove unused DIM variable from cli/install.sh
- Remove unused BLUE variable from cli/spawn.sh

Changed trap commands from double quotes to single quotes so variables
expand at trap execution time instead of definition time. This prevents
security issues where variables could be tampered with between trap
definition and execution.
Fixed 3 instances:
- cli/install.sh (2 instances): trap 'rm -rf "$tmpdir"' EXIT
- test/run.sh (1 instance): trap 'cleanup' EXIT

Changed set -uo pipefail to set -eo pipefail to align with commit #27
which removed nounset from all other scripts due to incompatibility
with optional env var checks (SPRITE_NAME, OPENROUTER_API_KEY, etc.).
This file was missed in the original nounset removal sweep.
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Added comprehensive test suite for cli/ TypeScript code:
- 37 tests covering manifest.ts, commands.ts, and integration scenarios
- Tests for manifest loading, caching, network fallback, and validation
- Tests for all CLI commands (list, agents, clouds, run, help, etc.)
- Integration tests for end-to-end workflows
- ~900 lines of test code covering ~635 lines of source
Test infrastructure:
- Added vitest as test runner for fast execution
- Created isolated test environment with mocked cache directories
- Mocked network calls to avoid external dependencies
- Test coverage for critical paths: caching, offline mode, error handling
All tests passing with proper isolation and cleanup.
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
- Replace empty catch blocks with proper error logging
- Add input validation for agent and cloud names in cmdRun and cmdAgentInfo
- Add detailed error messages for network failures and manifest validation
- Improve error context in execScript, cmdImprove, and cmdUpdate
- All errors now log helpful context instead of failing silently
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
The autonomous refactoring added `set -euo pipefail` but the scripts
check optional env vars with `[[ -n "$VAR" ]]` which is a fatal error
under nounset when the var isn't set (e.g. SPRITE_NAME, OPENROUTER_API_KEY).
Fix: downgrade to `set -eo pipefail` across all 42 affected files.

Three issues broke the OAuth callback server on macOS:
1. echo -e doesn't work in bash 3.x — \r\n appears as literal text
in the HTTP response, browser gets malformed headers.
Fix: pre-write response with printf to a file before the subshell.
2. local variables inside ( ... ) & subshell — undefined behavior in
bash 3.x since subshells aren't function scope.
Fix: use plain variables in subshells.
3. ((elapsed++)) when elapsed=0 evaluates to falsy — set -e kills
the script on the first iteration of the timeout loop.
Fix: use elapsed=$((elapsed + 1)) instead.
Also simplified nc_listen detection to only check for BusyBox
(the -p flag check could misfire on macOS nc).
Applied to all 10 lib/common.sh files.
