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.

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

Tool Defect types Suggested rewrite
check_dependency
no_return_description
Look up a package in quantakrypto's known quantum-vulnerable dependency database (the classical crypto it exposes). Provide 'name' and optional 'ecosystem' (default npm). Returns whether the package is flagged as quantum-vulnerable and, if so, which classical algorithm(s) it relies on.
probe_endpoint
no_return_description
Actively probe ONE live TLS/SSH endpoint YOU OWN for post-quantum readiness (PQC-hybrid key exchange X25519MLKEM768, classical certificate posture). REQUIRES an ownership attestation: set i_own_this=true to confirm you are authorized to test the target. Refuses CIDR ranges / wildcards / lists — one host at a time. Performs only a benign, unauthenticated handshake and never modifies the endpoint. Returns the handshake outcome: whether a PQC-hybrid key exchange was negotiated, the classical certificate/algorithm posture observed, or an error if the probe was refused or failed. NOTE: this is the ONLY quantakrypto MCP tool that opens a network connection; the server is otherwise offline. Over HTTP it is disabled unless the operator sets QUANTAKRYPTO_MCP_ALLOW_NETWORK=1.

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
remediate_findings triage_findings high Both take the identical 'findings' array from scan_path and produce a deterministic REQUEST bundle for the host agent to reason over; a task like 'handle these scan findings' doesn't clearly indicate whether the agent wants exposure/priority triage or fix remediation, and the tools' near-identical schemas and phrasing invite the wrong pick.
apply_triage triage_findings medium Both are named around 'triage' and operate on findings/verdicts; an agent asked to 'triage these findings' might call apply_triage directly without first calling triage_findings to generate verdicts, since apply_triage's description also mentions triage verdicts prominently.
apply_triage apply_verified_patch low Both are 'apply_*' tools that deterministically finalize an agent's prior work (verdicts vs. patches), but their domains (triage scoring vs. code patch verification) are distinct enough that confusion is unlikely except from name-pattern matching alone.
get_fix_examples verify_fix low Both relate to 'fix' and classical crypto code, but one returns illustrative before/after examples while the other checks a snippet for remaining vulnerabilities; a task like 'show me how to fix this' vs 'check if this fix worked' are phrased differently enough to usually disambiguate, though a vague 'fix this' request could momentarily cause hesitation.
