ChartForgeX AGENTS.md

Repository instructions for ChartForgeX, a dependency-free engine that renders charts and visual blocks as SVG, HTML, PNG, reports, dashboards, emails, documentation, and static sites.

In plain words
What is it for?
Use them when changing renderers, adapters, chart data structures, visual blocks, tests, examples, or support for the listed .NET versions.
Why use it?
They keep changes reusable and predictable across output formats while preventing product-specific features from being added to the rendering engine.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ChartForgeX AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Agent Guidance

ChartForgeX is a dependency-free rendering engine. Keep changes generic, testable, and reusable across SVG, HTML, PNG, reports, dashboards, email, documentation, and static site output.

Boundaries

  • Keep ChartForgeX free of runtime package dependencies.
  • Keep static rendering deterministic and script-free by default.
  • Put host-specific browser behavior in adapter packages such as ChartForgeX.Interactivity.Html.
  • Do not move dashboard shells, filters, inspectors, data collection, Active Directory calculations, or product-specific page layout into ChartForgeX.
  • Keep topology product-neutral. Host projects map their own data into TopologyChart.
  • Keep non-chart exact facts in ChartForgeX.VisualBlocks; do not force tables, lists, or KPI cards into chart series.

Change Expectations

  • Add or update smoke tests for new renderer behavior.
  • Add or update generated examples when a change affects visible output.
  • Preserve SVG and PNG parity for visual polish.
  • Preserve net472, netstandard2.0, net8.0, and net10.0 support.
  • Breaking changes are allowed when they produce a cleaner architecture, better usability, or a simpler public API. Prefer intentional migration notes over compatibility layers that preserve awkward designs.
  • Do not add NoWarn suppressions.
  • Keep production source files under the repository line-budget expectation.
  • Prefer shared helpers for color math, mark surfaces, line layers, text fitting, map surfaces, and validation instead of local renderer copies.

Documentation

  • Keep README.md readable as the product and developer entry point.
  • Keep durable reference material in focused files under docs/.
  • Keep active future work in TODO.md.
  • Do not create extra roadmap, handoff, or "next work" documents for ordinary follow-up items.
  • Remove stale "next" language once the described work has landed.

Validation

Use the repository quality loop before trusting visual or packaging changes:

./Build.ps1 -Configuration Release

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
