dotnet-engineer

dotnet-engineer is a skill for Claude Code, Codex from nelson820125/iforgeai. It costs 0 tokens per session (1,883 once invoked), scanned A, original, MIT.

A .NET and C# backend development role for building server-side features, APIs, database access, and application services. .NET is Microsoft's software platform, while ASP.NET Core is its web framework.

In plain words
What is it for?
Use it to implement ASP.NET Core endpoints, Entity Framework or other database operations, service and repository code, and related backend features.
Why use it?
It gives backend implementation work a defined role and keeps database changes aligned with the project's chosen schema approach. It also specifies which project files and workflow documents to use.

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

dotnet-engineer 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.

How it starts

The opening of the file, as written. The whole thing — 149 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Output Language Rule

Read output_language from .ai/context/workflow-config.md. Write ALL deliverables and code comments in that language. If the file is absent or the field is unset, default to en-US.

DB Approach Rule

Read db_approach from .ai/context/workflow-config.md before starting any database-related implementation:

  • database-first (default when unset): The authoritative schema is defined in .ai/temp/db-init.sql produced by the DBA. You must implement ORM entity classes and repository code that matches this schema exactly. Do NOT use dotnet ef migrations add to initialise the database — the database is initialised from the DBA's SQL script.
  • code-first: You are responsible for driving the schema through ORM migrations. Workflow:
    1. Read .ai/temp/db-design.md (DBA design document) as the reference for field types, constraints, indexes, and default values
    2. Implement entity classes faithfully according to the design document
    3. Run dotnet ef migrations add {MigrationName} to generate the migration
    4. Run dotnet ef database update (or equivalent) to apply it — this replaces db-init.sql
    5. Document each migration task in the WBS and work log with its migration name and purpose

Phase Mode

This skill operates in two modes depending on how it is invoked:

Mode Trigger Task Output
/contract digital-team Phase 5a Define full API contract schemas in api-contract.md .ai/temp/api-contract.md (fully detailed, ready for frontend review)
/develop (default) digital-team Phase 6b, or standalone invocation Implement backend code based on api-contract.md + wbs.md Source code + work log

Contract mode (/contract) rules:

  • Read .ai/temp/api-contract.md (architect's skeleton) and .ai/temp/wbs.md
  • Fill in Request schema, Response schema, HTTP status codes, and validation rules for each endpoint
  • Do NOT write implementation code in this mode — output is documentation only
  • The completed contract is reviewed by the frontend engineer before development begins

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.

dotnet-engineer is a skill published in the GitHub repository nelson820125/iforgeai (12 stars, last pushed 26d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,883 tokens. 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.
