Troubleshooting

Start with the command that matches the failing surface, then inspect the effective settings and credentials.

Baseline Checks

kosmokrator --version
kosmokrator smoke:startup --json
kosmokrator config paths --json
kosmokrator settings:doctor --json

For source checkouts:

composer install
php vendor/bin/phpunit
php vendor/bin/pint --test

Provider Or Model Fails

kosmokrator providers:list --json
kosmokrator providers:status --json
kosmokrator providers:status openai --json
kosmokrator settings:get agent.default_provider --json
kosmokrator settings:get agent.default_model --json
kosmokrator settings:options agent.default_model --provider openai --json

Common fixes:

Symptom	Fix
Missing API key	`printf %s “$OPENAI_API_KEY”
Wrong default model	kosmokrator settings:set agent.default_model <model> --provider <provider> --json
OAuth provider not logged in	kosmokrator providers:configure codex --device --json
Custom provider unreachable	Verify providers:custom:list --json, URL, auth mode, and model ID.

Headless Run Hangs Or Exits Early

Use explicit guards:

kosmokrator -p "Run tests" --max-turns 10 --timeout 600 --output-format stream-json

Checks:

Symptom	Fix
Needs an approval modal	Use a policy that fits automation, or configure permissions.
Writes are denied	Verify --mode edit, tools.denied_tools, blocked paths, and permission mode.
Too many repeated tool calls	Check stream JSON for stuck detection nudges and lower task scope.
No session should be persisted	Add --no-session.

Permission Denied

kosmokrator settings:get tools.default_permission_mode --json
kosmokrator settings:get tools.denied_tools --json
kosmokrator settings:get tools.blocked_paths --json
kosmokrator settings:get tools.allowed_paths --json

Remember:

• denied_tools always wins.
• Blocked paths always win unless explicitly allowed.
• Plan and Ask modes remove write tools before permission evaluation.
• Prometheus auto-approves governed calls, but does not bypass hard denies.
• Integration and MCP read/write permissions are separate from native tool approval.

Integrations Fail

kosmokrator integrations:list --json
kosmokrator integrations:status --json
kosmokrator integrations:doctor plane --json
kosmokrator integrations:fields plane --json
kosmokrator integrations:schema plane.list_issues

Common fixes:

Symptom	Fix
Integration not active	kosmokrator integrations:configure plane --enable --json
Missing credentials	Use integrations:fields then integrations:configure --set key=value.
Named account not found	Pass --account <alias> consistently.
Write denied in headless mode	Set write permission to allow or use --force only for trusted automation.
Function name unknown	Use integrations:search <query> --json.

MCP Fails

kosmokrator mcp:list --all --json
kosmokrator mcp:status --json
kosmokrator mcp:doctor --json
kosmokrator mcp:tools <server> --json

Common fixes:

Symptom	Fix
Project server is untrusted	Review command, then run kosmokrator mcp:trust <server> --project --json.
Env token missing	`printf %s “$TOKEN”
Tool discovery fails	Confirm server command exists in PATH and can run outside KosmoKrator.
Tool treated as write	Set --read allow --write ask/allow explicitly; tools without readOnlyHint are conservative.
Config shape not detected	Use top-level mcpServers, or import compatible servers JSON with mcp:import.

Web Search Or Fetch Fails

kosmokrator web:providers --json
kosmokrator web:doctor --json
kosmokrator settings:list --category web --json

Common fixes:

Symptom	Fix
Search tool unavailable	kosmokrator settings:set web.search.enabled on --json and restart.
Provider unconfigured	Use web:configure <provider> --api-key-env ... --enable.
External fetch unavailable	Set web.fetch.allow_external to on and choose a provider.
Crawl unavailable	Set web.crawl.enabled and choose Tavily or Firecrawl.

Telegram Gateway Fails

kosmokrator gateway:telegram:status --json
kosmokrator settings:list --category gateway --json
kosmokrator secrets:status gateway.telegram.token --json

Common fixes:

Symptom	Fix
Gateway disabled	kosmokrator gateway:telegram:configure --enabled on --json
Missing token	Set gateway.telegram.token or KOSMOKRATOR_TELEGRAM_BOT_TOKEN.
Bot ignores group	Mention/reply to the bot, or configure free_response_chats.
Unauthorized chat/user	Check allowed_chats and allowed_users.

Terminal UI Looks Wrong

kosmokrator --renderer=ansi --no-animation
kosmokrator settings:set ui.renderer ansi --global --json

Checks:

Symptom	Fix
TUI rendering glitches	Use a modern terminal, or force ANSI.
Animation causes startup issues	Use --no-animation or set ui.intro_animated off.
Colors are unreadable	Try ANSI mode and check terminal theme contrast.
Readline issues in remote shell	Force --renderer=ansi.

If syntax highlighting or MDX fails, check fenced code blocks first. Astro/Starlight treats MDX as JSX, so raw < and { in prose sometimes need escaping or code fences.
