Chart Master — Financial Visualization AgentFinance Skill
A single-file collection of chart layouts and styling instructions. The examples use illustrative numbers, with identified risk/reward and midpoint arithmetic errors. The Mermaid axis definition and RSI annotation setup also need correction. HTML rendering loads and executes external JavaScript; ASCII does not. The snapshot does not validate data, derive every displayed indicator or establish a trading signal, and rendering was not tested.

How the assessment score works
Pineify weights evidence recorded from the captured files: Skill structure 15%, Instruction clarity 20%, Dependency transparency 20%, Permission transparency 20%, Safety guardrails 15%, Finance task fit 10%. Each signal receives full credit for Yes, one-quarter credit for unknown, and none for No.
The score is not an output accuracy test or user rating. Read the findings and financial assumptions even when the score is high. Risk labels summarize recorded permissions and findings; they do not measure investment risk or certify that installation is safe.

Permissions
FilesystemRead
NoThe skill does not read local files. It accepts financial data or analysis output as input.
FilesystemWrite
NoThe skill does not write local files. Output is presented as text (Mermaid, ASCII, or HTML code blocks).
NetworkAccess
YesData verification step requires fetching current price, 52-week range, and market cap via web search or asking the user.
ShellExecution
NoPure prompt skill with no code execution.
CodeExecution
YesThe HTML output contains JavaScript and loads Chart.js from a CDN when rendered; returning a text snippet alone does not run it. No rendering or third-party execution was tested.
ExternalCredentials
NoNo external credentials required.
Dependencies
Chart.js or Mermaid renderer
Conditional on chosen output; HTML templates load an unpinned Chart.js CDN script
The captured directory contains templates, not bundled renderer code.

High
Correct the illustrative valuation and risk/reward arithmetic
The support map uses current price 235 and support 215, a risk of 20; an upside of 7 therefore gives reward/risk 0.35, not a favorable 3-to-1 reward. Its listed 228 resistance is below current price and 250 resistance is 15 above it, so the displayed 7 does not match either. In the fair-value example, the midpoint of 198 and 241 is 219.50, about 3.5% above 212, not 7%. These are template errors, not measured company performance.
Medium
The examples are layouts, not computed market evidence
Price, MA, RSI, histogram, valuation and score arrays are supplied numbers. The source does not derive VaR/CVaR from returns, calculate the moving averages or implement a candlestick chart despite mentioning one in frontmatter. Replace all example arrays with sourced data; disclose observation interval, adjustment method, units, tail convention and valuation assumptions. Keep unknown values missing and do not use recalled estimates as current data.
Medium
Some templates need renderer corrections
The horizontal Mermaid example places categories on y-axis, which the current XY chart contract does not permit; horizontal orientation does not change the syntax contract. The RSI HTML loads only Chart.js and places annotation at options.annotation; current annotation integration requires the plugin and options.plugins.annotation. The price/volume example overlays two axes on one canvas rather than creating two separate panels. No template was executed during this static review.
Low
No supporting files or README in the snapshot
The skill directory contains only SKILL.md with no README, reference files, or supporting documentation. All 12 chart type templates and style guidelines are inline in the 22,113 byte SKILL.md.
