routa: Skill for Claude Code

.claude/skills/evolution-architecture-review/SKILL.md

evolution-architecture-review is a skill for Claude Code from phodal/routa. It costs 72 tokens per session (908 once invoked), scanned A, original, MIT.

A repository-based review of how safely an application’s architecture can change over time. It examines boundaries, runtime behavior, verification checks, and possible evolution steps.

In plain words
What is it for?
Use it to assess module boundaries, task flows, failure visibility, tests, fitness functions, and incremental, rollback-friendly architecture improvements.
Why use it?
It replaces generic architecture opinions with findings tied to the codebase and identifies risks in coupling, observability, and delivery.

About the project

Routa is a workspace-based coordination platform for delivering software with multiple AI agents, keeping goals, tasks, sessions, traces, evidence, and review decisions visible on a shared board. It is intended for teams managing agent-assisted development across web and desktop applications. The catalogue contains skills and instructions for working with Routa's delivery workflows.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.
    Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.

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

evolution-architecture-review 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 9d 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 — 131 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Goal

Assess how safely this codebase can evolve, using parallel analysis where possible.

Do not give generic architecture advice. Ground every conclusion in repository evidence.

Default to read-only analysis. Do not edit code unless the user explicitly changes the task from review to implementation.

Default Mode

Prefer a 4-lens review in parallel. If subagents or Task are available, use them. If not, run the same lenses sequentially yourself.

Lens 1: System shape and boundaries

  • Identify major modules, ownership boundaries, and dependency direction.
  • Look for hidden coupling, duplicated semantics, and unclear seams.

Lens 2: Runtime flow and operability

  • Inspect task flow, orchestration, state transitions, control-plane behavior, and failure visibility.
  • Focus on whether the system is observable and debuggable during change.

Lens 3: Fitness and verification

  • Inspect hard gates, tests, contract checks, parity checks, and evidence loops.
  • Determine whether the architecture has executable constraints or mostly human judgment.

Lens 4: Evolution path

  • Propose incremental change steps, rollback-friendly sequencing, and smallest viable improvements.
  • Avoid rewrite-first recommendations.

Starting Points

Read these first unless the user narrows scope:

  • AGENTS.md
  • docs/ARCHITECTURE.md
  • docs/product-specs/FEATURE_TREE.md
  • docs/fitness/README.md
  • docs/blog/routa-kanban-agent-team-management.md
  • docs/blog/harness-fitness-function.md
  • src/core/orchestration/
  • src/core/kanban/
  • src/core/specialists/
  • crates/routa-core/src/workflow/
  • crates/routa-server/src/

Then expand only where evidence requires it.

Scope Hygiene

Treat the main repository tree as authoritative. Unless the user explicitly asks otherwise, ignore duplicate or generated trees such as:

  • .worktrees/
  • .routa/repos/
  • node_modules/
  • .next/
  • target/
  • out/
  • dist/
  • coverage/
  • tmp/
  • test-results/

When using Glob, Grep, or Task, state these exclusions explicitly so subagents do not waste time or cite mirrored files.

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.
