Add explicit identity and permission preflight tools

Expose machine-readable principal/tenant confirmation and a non-mutating permission check so agents can verify both before destructive actions.

Description evidence

Defects and rewrites.

0 defects found across the exposed tool descriptions. Suggested rewrites make purpose, inputs, boundaries, and returns easier for an agent to understand.

No description defects were flagged in this assessment.

Selection evidence

Confusable tool pairs.

4 pairs where similar names or overlapping descriptions may send an agent toward the wrong tool.

Tool A Tool B Confidence Why they collide
create_standing_order create_monitored_area high Both descriptions open with nearly identical framing ('Put an area under CONTINUOUS watch' vs 'Put a place under continuous satellite measurement') and both are created with just a bbox, so a task like 'keep continuous watch over this region' is genuinely ambiguous — only deeper reading (scheduled analyst question re-answer vs metric-based satellite measurement) disambiguates.
list_standing_orders list_monitored_areas medium Both are free, parameterless list tools for continuously-watched areas on the key. A task like 'show me all the areas I'm watching / my active monitors' plausibly maps to either; only the underlying distinction (scheduled analyst questions vs satellite quantity measurements) separates them.
search_imagery plan_event_imagery medium A task like 'get satellite imagery for this event' could plausibly route to search_imagery (the catalog search) even though plan_event_imagery is the intended one-shot wrapper given an event_id; an agent that skips the guidance ('Prefer this over several search_imagery calls') may pick the wrong member.
list_monitored_areas get_monitored_area low Tasks like 'get my monitored areas' are somewhat ambiguous between the summary list and single-area detail (list already reports latest value and anomaly flag), but the singular name, required area_id, and clear history-vs-summary schema descriptions make wrong selection unlikely.
