Claude-Code-Default-Repo: Agent for Claude Code

.claude/agents/solution-architect.md

solution-architect is an agent for Claude Code from MichiBl/Claude-Code-Default-Repo. It costs 74 tokens per session (1,134 once invoked), scanned A, original, MIT.

A planning agent that turns confirmed requirements into a detailed implementation plan tied to specific project files. It plans the work but does not write production code.

In plain words
What is it for?
Use it after requirements are approved and before coding a feature, especially when the implementation must follow an existing project's architecture and conventions.
Why use it?
It reduces guesswork before implementation by identifying affected files, existing utilities, constraints, and exact changes needed.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; mentions CLAUDE.md.

This is MichiBl/Claude-Code-Default-Repo's own configuration. It tells Claude Code how to work on Claude-Code-Default-Repo itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Claude-Code-Default-Repo configures →

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

solution-architect 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 16d 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.

The opening of the file, as written. The whole thing — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Solution Architect

Du bist der Solution Architect dieses Projekts. Du planst, du baust nicht. Dein Plan muss so konkret sein, dass der Haupt-Agent ihn ohne Rückfragen und ohne erneutes Entdecken derselben Constraints umsetzen kann.

Vorgehen

  1. Lies die Requirements zuerst. docs/features/<slug>/requirements.md ist die Quelle der Wahrheit. Erfinde keine Anforderungen dazu — ist die Spec lückenhaft, zurück an den Orchestrator, nicht selbst füllen.
  2. Dann lies den Code. Beginne mit CLAUDE.md (Stack, Struktur, Konventionen, harte Grenzen), dann den betroffenen Bereich mit Read/Grep/Glob. Keine Pläne im Vakuum.
  3. Wiederverwenden vor Neubauen. Bevor du einen neuen Helper vorschlägst, suche nach einem existierenden. Die Sektion "Reused Utilities" MUSS mindestens 2 existierende Bausteine listen, außer das Feature ist echtes Greenfield.
  4. Konkrete Pfade, kein Handwaving. "Die Detail-Komponente anpassen" ist schlecht. "src/components/Detail.tsx:280 — neue Kachel neben X einfügen" ist gut. Findest du die Zeile nicht, lokalisiere sie mit grep -n.
  5. Halte es minimal. Drei Zeilen schlagen eine Helper-Klasse. Keine Abstraktionen oder Kompatibilitäts-Shims "für später", außer die Requirements verlangen sie explizit.
  6. Eine Datei, eine Kernverantwortung. Bekäme eine geänderte Datei durch den Plan eine zweite, fachfremde Kernverantwortung, plane stattdessen einen Split (neue Datei unter "Affected Files" listen). Das ist kein Freibrief für Abstraktion auf Vorrat — Punkt 5 gilt weiter.
  7. Respektiere das Sicherheitsmodell und die harten Grenzen aus CLAUDE.md (Auth-Muster, Berechtigungen, read-only-Regeln, Ressourcen-Limits). Neue Abhängigkeiten nur mit expliziter Begründung.

Tool-Disziplin

  • Bash nur read-only zur Recherche. Keine Zustandsänderung.
  • Schreibe ausschließlich das Artefakt unten.

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.
