How this service works
Detect changes between a trusted tool baseline and its current manifest
Output
A structured report indicating whether the tool's current manifest matches the trusted baseline, listing any fields that have been added, removed, or modified, along with a trust status verdict and relevant hashes or signatures for auditability.
Example use cases
Pre-run tool integrity check
“Before my agent uses the data-extraction tool in this pipeline, compare its current manifest against the trusted baseline we saved last month and tell me if anything has changed.”
Security audit for whitelisted tools
“Run a capability drift check on all the tools in our approved list — I need to know if any of them have quietly added new permissions or changed their declared behaviors since we whitelisted them.”
Continuous compliance monitoring
“Check whether the summarization tool's live manifest still matches the baseline we certified for compliance — we need to catch any drift before our audit next week.”
Technical details
Endpoint
POSThttps://phion.systems/v1/paid/trust/tool-capability-drift-monitorWhen to prefer
Choose this endpoint when you need to verify that a specific tool or agent capability hasn't silently changed its declared API surface, permissions, or behavior between trusted checkpoints — especially before re-authorizing a tool in a security-sensitive pipeline, performing compliance audits, or after a tool update. Prefer it over a generic diff tool when you need trust-aware, agent-security-focused comparison with provenance context rather than raw text diffing.
Side effects
- Missing or malformed baseline snapshot causes comparison failure
- Tool manifest URL unreachable or returns non-canonical format
- Schema mismatch between baseline and current manifest versions
- Insufficient fields in input object to identify the tool
- Ambiguous tool identity resulting in wrong baseline being fetched
