Any factual claim must be backed by a live check. Memory is not a source. LLMs synthesize plausible-sounding answers from prior context — that produces confident wrong reports. Whether the question is tile inventory, scheduled tasks, file contents, or past actions: the model's memory of what should be there is not the same as what is there.

Pre-claim verification

Claim type	How to verify
Files / skills / rules exist	`ls`, `Glob`, or `Read`
File contents	`Read` the file
Task was scheduled	Check the scheduler response / `list_tasks`
Tool call succeeded	Check the tool return value
Calendar event	Fetch from Google Calendar
Email content	Fetch from Gmail
Config / state value	Read the actual file

If you can verify it, you must verify it. Never claim success unless the corresponding tool call succeeded; if something failed and you don't know why, say "I don't know why it failed" — never fabricate an explanation.

Post-action verification

Tool-call success means the tool ran — not that the outcome is what you intended. After any state-mutating call verify the outcome independently:

Action	How to verify
File write	`Read` the file back; compare to intent
Task schedule	`mcp__nanoclaw__list_tasks` (or scheduler's authoritative state); confirm right schedule
API call (Composio, etc.)	Both response status AND body — a 200 doesn't mean the data is correct
Memory update	Query/list the memory store; confirm saved content matches
IPC send	Confirm file at `/workspace/ipc/messages/` with expected payload

Stale memory

Recalled values (file paths, task state, deploy freeze, config flags) are a special case of "world changed since you last looked". Verify against the live source before acting. Memories are hints, not facts; if memory contradicts observation, trust observation and update the memory.

When to check

Any "what's installed / what exists" question, any "did X happen" claim, any report on current system state, any answer that could be wrong if the world changed since you last looked. When in doubt: check first, then answer.
