Dotnet Developer

STOP - Read before ANY tool call

1. Read {{GUARDRAILS_PATH}}
2. Read _shared/sdd-artifacts/SESSION.md; load session-state for $Cwd
3. If the relevant gate is not approved: STOP - ask user (pt-BR) - do NOT Write/Shell
4. SDD/develop skills: after ONE step/task, STOP session - handoff only
5. This skill body is English; user-facing prompts may be (pt-BR)

Step -1 - Gate check (report in chat before continuing)

Gate check:
[ ] guardrails.mdc read
[ ] SESSION.md read; session-state loaded
[ ] PIPELINE.md read (SDD skills only)
[ ] User confirmed current action (sim)
-> If any unchecked: STOP

Trigger

Invoke when the user asks for: /dotnet-developer, dotnet fix, implement .NET feature, or for small backend work that does not need a full PRD/PLAN cycle.

Outcome

Working .NET code and tests in the open workspace: build and tests green, on a valid feature branch, with optional commit handoff. Does not replace SDD for multi-step or cross-repo features.

When to prefer SDD instead

Recommend /sdd-spec -> sdd-plan -> sdd-develop if two or more apply:

Lazy-load (only when needed)

Do not preload code-guidelines/languages/** or corporate pipeline docs. MUST NOT glob architecture/** — load one style overlay from ARCH/CONTINUITY (brownfield: discover-first if style omitted).

Process

Step -1b - Caveman Mode (Full cap)

1. Read {{SDD_ROOT}}/preferences.json (create { "caveman_mode": false, "caveman_level": "full" } if missing).
2. If caveman_mode is false: continue without compression.
3. If true: load {{TOOLKIT_ROOT}}/skills/_shared/caveman/CAVEMAN.md; apply Full participation cap + prefs caveman_level (Lite skills never escalate); show once: [Caveman] Modo ativo (respostas compactas, level={effective}). Digite caveman off para desativar.
4. Honor caveman on|off|status|lite|full|ultra (and stop caveman / normal mode) during the session.
5. Auto-Clarity + never-compress gates/drafts/paths per CAVEMAN.md.

Subagent-first (before implement)

Classify complexity → consult capability subagents → if medium/complex and native: spawn ≤2 children (scoped paths + receipt); trivial stays in-parent; if subagents=none or Task unavailable → fallback in-parent (never hard-fail). Load SPAWN.md + subagent-first.md; do not paste guidelines into child prompts.

0. Workspace

Confirm target repo (*.sln / *.csproj). Read AGENTS.md / README.md. Summarize the user request and acceptance (from issue text, PRD snippet, or user description).

1. Guidelines (step 0.5)

Follow {{TOOLKIT_ROOT}}/skills/_shared/developer-common/step-0.5-review-guidelines.md: load dotnet-guidelines files needed for this task only. Confirm test stack: xUnit, Moq, Shouldly, Should_<Result>_When_<Condition>.

2. Branch (step 3)

Baseline branch from user or repo default. Create/checkout feature/<slug> or feat/<id> - never commit on main / master / develop.

3. Plan micro-steps

List 3-7 concrete tasks (files to touch, tests to add). Stay within one session when possible; checkpoint per context-management.mdc (>= 40% -> pause, offer /commit).

4. Implement

Match existing project patterns (Glob/Read similar types first).

Apply the one ARCH-matched architecture overlay (see lazy-load table) and csharp-patterns.md from {{TOOLKIT_ROOT}}/skills/_shared/dotnet-guidelines/ while writing - do not paste full bodies into chat. Never glob architecture/**.

5. Tests

Add or update tests for changed behavior. Prefer integration tests for real flows when the project already uses them; unit tests for isolated logic.

6. Build and test

dotnet build
dotnet test --no-build

Fix failures within scope. Ask before running full-solution tests if the repo is very large.

7. Pre-commit (step 3.5) and handoff

Run {{TOOLKIT_ROOT}}/skills/_shared/developer-common/step-3.5-precommit-validation.md when appropriate. Offer /commit - do not commit automatically.

Before push/PR, run {{TOOLKIT_ROOT}}/skills/_shared/developer-common/step-7-checklist.md and {{TOOLKIT_ROOT}}/skills/_shared/dotnet-guidelines/checklist.md.

8. SDD escalation

If scope grows during work, stop and recommend:

/sdd-spec - [feature description]
# then
/sdd-plan - PRD/...
# then
/sdd-develop - PLAN/... - Step 1

Must not

• Paste guideline packs into child prompts (pass scoped paths + require receipt only)
• Spawn children for trivial work (keep in-parent)
• Hard-fail when capability subagents is none or Task is unavailable (use fallback in-parent)
• External work-item APIs, repo-mappings.json, or org-only pipeline/Key Vault mapping guides
• Obsolete test stacks or naming conventions (use xUnit/Moq/Should_When_ only)
• Obsolete guideline paths (use dotnet-guidelines/ only)
• Nested feature/base/... branches; commit on default integration branches
• Speculative features outside stated acceptance (YAGNI)
• Auto-commit or auto-PR without user request
• Deprecated SDD skill aliases in handoff text - use sdd-spec, sdd-plan, sdd-develop, commit only
