Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00110 | $0.03095 |
| Opus 5.5 | $0.00044 | $0.01238 |
| Sonnet 5.5 | $0.00022 | $0.00619 |
| Haiku 4.5 | $0.00011 | $0.00310 |
Grade A, and why
flexcel-vcl 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 1mo ago.
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.

FlexCel Studio for VCL / FireMonkey
This skill helps write Delphi (VCL, FMX, Lazarus/LCL, Linux/SKIA) and C++Builder code that uses FlexCel — the TMS Software library for working with Excel .xlsx / .xls files, exporting to PDF/HTML/images, and generating data-driven reports from templates.
When to use this skill
Activate whenever the user wants to, from Pascal/Delphi/C++Builder code:
- Read an Excel file (
.xlsxor.xls) — cell values, formulas, formatting. - Create or modify an Excel file programmatically.
- Generate reports by merging data into Excel templates.
- Export an Excel file to PDF, HTML, SVG, or images.
- Autofit rows/columns, render sheets, or measure cells.
- Target VCL, FireMonkey (desktop & mobile), Lazarus, or Delphi Linux.
FlexCel does not require Excel or any Office installation on the target machine. It has no OLE/COM dependency.
Two ways to create Excel files — pick one
Before writing code, decide which API fits the task:
| If the user wants to… | Use | Why |
|---|---|---|
| Read existing files, or build files cell-by-cell in code | TXlsFile API (FlexCel.XlsAdapter) |
Full programmatic control; no designer required. |
| Produce the same report repeatedly from changing data, with a styled layout | TFlexCelReport + Excel template (FlexCel.Report) |
Non-programmers can edit the template in Excel; code just provides data. |
When the user says "generate a report with company logo / nice formatting / many rows from a database", prefer Reports. When they say "read this file and extract values" or "create an Excel file with these calculations", prefer the API.
You can combine both: run a report to produce an in-memory TXlsFile, then manipulate it with the API, then export to PDF.
Quick-start recipes
All examples assume VCL. For FireMonkey replace FlexCel.VCLSupport with FlexCel.FMXSupport; for Lazarus use FlexCel.LCLSupport; for Delphi Linux use FlexCel.SKIASupport. The platform support unit goes in the main program (.dpr) uses clause only, not every unit.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

flexcel-vcl is a skill published in the GitHub repository SecondLifes/delphi-expert (3 stars, last pushed 1mo ago), licensed MIT. It adds 110 tokens to every session and 3,095 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
