omega_seal_run

Create immutable audit records by appending tamper-proof entries to a SHA-256 hash chain, ensuring evidence integrity for significant events.

Instructions

Appends a tamper-proof entry to the SEAL (Secure Evidence Audit Ledger) SHA-256 hash chain. Use this to create an immutable audit record of significant events, decisions, or state changes. Returns JSON with fields: seal_hash (hex string), chain_position (integer), timestamp (ISO 8601).

Tool call template

TDQS

A4.3/5.0
Behavior4/5

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

With no annotations provided, the description carries full burden and clearly discloses traits: tamper-proof, immutable, and the exact return fields (seal_hash, chain_position, timestamp). It could also note that entries cannot be deleted or modified.

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?

Two sentences deliver maximum information with minimal words: action, purpose, and return details are front-loaded and efficiently stated.

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?

Despite lacking annotations and output schema, the description fully covers the tool's function, parameters, and return fields. For a simple 2-param tool, nothing essential is missing.

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

Parameters3/5

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

Schema coverage is 100%, so the description adds only slight nuance (e.g., 'structured event metadata', 'outcome text to seal'), meeting the baseline but not significantly exceeding it.

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 uses a specific verb ('appends') and resource ('SEAL... hash chain'), clearly distinguishing it from sibling tools like omega_brain_report or veritas_mis_greedy which serve different purposes.

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

Usage Guidelines4/5

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

The description explicitly states when to use the tool ('to create an immutable audit record of significant events, decisions, or state changes'), but does not mention when not to use it or suggest alternatives.

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