JEVULON VII (JVII)

sentinel_oversight_monitor

Evaluates worker traces for retry loops, deadlocks, and toxic failure patterns, then returns a verdict: continue, quarantine, reroute, or halt.

Instructions

Evaluates a worker trace for retry loops, deadlocks, and toxic failure patterns (continue / quarantine / reroute / halt).

Behavior2/5

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

With no annotations, the description carries the full behavior burden. It names four verdicts (continue / quarantine / reroute / halt) but never says whether the tool merely recommends them or actually applies them — a critical distinction for a tool whose outcomes look like enforcement actions. Permissions, side effects, and whether it mutates worker state are all unstated.

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

Conciseness4/5

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

A single dense sentence that front-loads the verb and detection targets. Nothing is wasted, though the parenthetical verdict list makes it slightly overloaded.

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

Completeness3/5

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

For a 4-parameter diagnostic tool with no output schema, the parenthetical verdict list partially compensates by hinting at the return values. What remains missing is whether the verdict is advisory or enforced and when in a workflow the call belongs.

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 description coverage is 100%, so workerId, action, outputOrError, and recentTrace are already documented in the schema itself. The description adds no parameter meaning beyond that, which is the baseline case for full coverage.

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

Purpose4/5

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

The description gives a specific verb (Evaluates) plus the resource (a worker trace) and enumerates the failure classes it detects (retry loops, deadlocks, toxic failure patterns). It does not, however, distinguish itself from the close-sounding sibling sentinel_supervise, leaving the agent to guess which of the two to call.

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

Usage Guidelines2/5

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

There is no statement of when to invoke this tool versus sentinel_supervise, sentinel_shield_inspect, or sentinel_approve_escalation, and no prerequisites or exclusions. The only usage signal is implicit — that it is a diagnostic step on a worker trace — which the agent must infer.

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