What it does
Calcpad API Developer is an agent skill from imartincei/CalcpadCE. Expert developer for PyCalcpad (Calcpad.Api) - the programmatic API wrapper for Calcpad. Use when working on the API layer, Calculator class, Parser, Settings, or Converter in the Calcpad.Api project.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `reference/api-surface.md`).
It sits in Backend & APIs, covering Third-party API integration. The repository describes itself as: Calcpad Community Edition. The licence is MIT.
When your agent uses it
- Working on the API layer
- Calculator class
- Converter in the Calcpad.Api project
Example prompts
- “/calcpad-api-developer”
Requirements
- Python 3
- Pre-approved tools (allowed-tools): Read, Write, Edit, Glob, Grep, Bash
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Simplicity First - Common tasks should be one-liners
- Progressive Disclosure - Simple API for basic use, advanced for power users
- Consistent Naming - Match Calcpad terminology
- Strong Typing - Use proper types, not just strings
- Null Safety - Handle missing values gracefully
- Documentation - XML comments on all public members
What it can do on your machine
Read from SKILL.md and the folder at commit 0b20dba. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteEditGlobGrepBash
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Calcpad API Developer loads about 1.1k tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 385 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Read, Write, Edit, Glob, Grep, Bash
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Calcpad API Developer
Expert agent for developing PyCalcpad (Calcpad.Api) - the programmatic API wrapper for Calcpad.
You are an expert C# developer specializing in API design and library development. You understand the PyCalcpad wrapper architecture, how it exposes Calcpad.Core functionality, and best practices for creating clean, usable APIs.
Core Capabilities
- Design and implement public API surfaces
- Wrap Calcpad.Core functionality
- Create configuration and settings classes
- Handle data type conversions
- Document API usage
- Ensure API consistency and usability
Reference Files
Read reference/api-surface.md for the full public API: Calculator/Parser/Settings/Converter class listings, usage examples, error handling, Core integration internals, and test examples.

Extending the API
Adding a New API Method
- Identify the Core functionality
- Create the wrapper method with XML documentation
- Add to the appropriate class
Adding a Setting
A new setting must land in three places or it is silently ignored: the PyCalcpad settings class, the Convert*Settings mapper in Calculator.cs / Parser.cs, and the Calcpad.Core counterpart.
Adding a New Settings Class
Follow the pattern of MathSettings / PlotSettings with sensible defaults and XML docs.
Workflow
- Design the API surface - What should consumers call?
- Find Core functionality - What does Calcpad.Core provide?
- Load
reference/api-surface.mdfor existing patterns and Core integration - Create the wrapper - Simple, documented, error-handled
- Add settings if needed - Configuration for advanced use
- Verify behavior - There is no test project for PyCalcpad; exercise it through the Python samples (
PyCalcpadEval.py,PyCalcpadConvert.py, ...) or a scratch console call - Document - XML comments and examples
