analyze_cnsa_compliance

Check NSA CNSA 2.0 readiness of cryptographic algorithms, identify compliance gaps, and obtain a migration roadmap for National Security Systems.

Instructions

Check NSA CNSA 2.0 readiness for National Security Systems.

Analyzes algorithms against CNSA 2.0 requirements (AES-256, SHA-384, ML-KEM-1024, ML-DSA-87), tracks transition timeline, and assesses crypto agility.

Args: algorithms: Comma-separated algorithm names (e.g. "AES-256,ECDSA-P384,SHA-256") include_gap_analysis: Include full gap analysis with migration roadmap (default True) scan_text: Optional source code or config text to scan

Returns: JSON CNSA 2.0 compliance analysis with gap assessment

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries full burden. It discloses that the tool performs analysis, tracks transition timeline, assesses crypto agility, and returns JSON. However, it does not mention whether it modifies any state or has side effects, which is a minor gap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise (about 4 sentences) with a clear 'Args:' section. It front-loads the purpose and contains no redundant information. Every sentence adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so the description's mention of returning JSON is sufficient. Parameter documentation is complete. The tool's complexity is moderate, and the description covers essential aspects comprehensively.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Input schema has 0% description coverage, but the description provides clear meaning for all three parameters: algorithms as comma-separated names, include_gap_analysis as optional boolean with default, scan_text as optional string. This fully compensates for the schema gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool checks NSA CNSA 2.0 readiness for National Security Systems, specifying the verb, resource, and context. It distinguishes from sibling tools like check_fips_compliance and generate_compliance_report.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for CNSA compliance analysis but does not explicitly state when to use this tool over alternatives like assess_pqc_readiness or audit_crypto_usage. No when-not or exclusion criteria are provided.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
