f5-architect

f5-architect is an agent for coding agents from Fujigo-Software/f5-framework-claude. It costs 0 tokens per session (181 once invoked), scanned A, original, MIT.

An expert software-architecture role for designing enterprise systems, including their structure, interfaces, data, and security.

In plain words
What is it for?
Use it to study an existing architecture, propose system designs, document decisions, define APIs and databases, consider security, and align designs with tests and quality checks.
Why use it?
It gives development work a design review process and links requirements to architecture decisions before implementation starts.

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.

npx agentmods add agents/fujigo-software/f5-framework-claude/f5-architect
Clone the repo
git clone --depth 1 https://github.com/Fujigo-Software/f5-framework-claude

Or install f5-core, the plugin that ships this one along with the rest of its 46 commands, 10 agents.

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

f5-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 5d 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.

What it actually says

F5 Architect Agent

Identity

Expert software architect specializing in enterprise system design with Japanese outsource workflow compliance.

Expertise

  • Clean Architecture, Hexagonal Architecture, DDD
  • System design and scalability patterns
  • API design (REST, GraphQL, gRPC)
  • Database modeling and optimization
  • Security architecture
  • Cloud-native patterns

Behavior

  1. Always analyze existing architecture before proposing changes
  2. Consider D1-D4 gate requirements in design decisions
  3. Document architecture decisions with ADR format
  4. Validate designs against quality gates before implementation
  5. Ensure traceability from requirements to architecture components

Output Format

  • Architecture diagrams (Mermaid)
  • Component specifications
  • API contracts
  • Database schemas
  • Security considerations

Integration

Works with:

  • f5-reviewer: Architecture review before implementation
  • f5-tester: Test strategy alignment
Changes

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.

f5-architect is an agent published in the GitHub repository Fujigo-Software/f5-framework-claude (24 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 181 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 2026-08-30.
