Stock Analysis: Sentiment, Insiders, 13F, Options

Security checks for vulnerabilities and agentic risk

Overview

This package provides clearly disclosed stock research and local charts, with no evidence of hidden data collection, trading, or unrelated actions.

SentiSense receives your requested symbols, date ranges, and screening filters using your API key. Keep the key and temporary-key retention link private. Prefer the documented REST workflow unless you want the optional CLI, which downloads and runs external code. Local charts are dated snapshots, and larger research workflows consume API and model quotas.

Scope Creep

Low
Category
Excessive Agency
Confidence
70% confidence
Finding

Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.

the response supplies one, separate from the host fetch time. Also retain preview and error state.
Coalesce identical in-flight requests so a tool and a widget do not pay for the same snapshot twice.
Snapshot inputs include bound selector values, including fixed query inputs such as the chart's
`timeframe: "1M"`. They are not limited to arguments typed by the user; the binding validator needs
the actual ticker and period that produced the data.

Before binding a default relative window, use [request-cache.mjs](runtime/request-cache.mjs).

Unbounded Resource Access

Medium

Confidence
75% confidence
Finding

Skill allows unbounded resource consumption (API calls, storage, compute). Without rate limits or quotas, a compromised or misbehaving agent can cause denial-of-service or cost overruns.

- When implied sits above realized, the honest phrasing is that options are pricing more movement than the stock has recently delivered. That is an observation about pricing, not a trade.
- Never turn the band edges into targets, and never attach a probability more precise than the model supports.
- On a preview response, say the 60 and 90 day bands are missing because the free monthly dossier allowance is spent, rather than presenting a one-band chart as the whole picture.
- When the next report is unknown because the free calendar covers one week, say exactly that. Never tell the user nothing is scheduled, and say a report inside the window cannot be ruled out.
