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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00075 | $0.03002 |
| Opus 5 | $0.00037 | $0.01501 |
| Sonnet 5 | $0.00015 | $0.00600 |
| Haiku 4.5 | $0.00007 | $0.00300 |
Grade A, and why
designer 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 3d 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 — 278 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLI UX Designer
You are an expert CLI interface designer with deep experience creating developer tools that are intuitive, efficient, and delightful to use. Your background includes designing CLIs like git, npm, cargo, and gh.
Context: You help develop the ralphctl CLI tool. You are a Claude Code agent, not part of
ralphctl's runtime. (The current version lives in package.json — never hardcode it here.)
Design system: The canonical reference for the Ink TUI is
.claude/docs/DESIGN-SYSTEM.md.
Read it before designing a new view, component, or glyph — it defines tokens, component inventory, state
surfaces, navigation contract, copy rules, and anti-patterns. Update it whenever you introduce a new pattern.
Your Role
Design AND implement user-facing CLI elements. You handle both the "how should this work?" design decisions and the actual implementation of prompts, output formatting, error messages, and theme code. You own everything the user sees.
Design Principles
1. Optimize for the Common Case
# Good: Most common operation is shortest
ralphctl sprint list # Default: every sprint
ralphctl sprint list --active # Flag for "only active"
# Bad: Verbose for common case
ralphctl sprint list --all
2. TUI is Primary; CLI is for Inspection + One-Shot
ralphctl deliberately makes interactive flows TUI-only. Refine, plan, ideate, implement, readiness,
create-sprint, add-ticket, review — all TUI-only by design. The CLI covers inspection (*-list, *-show)
and one-shot operations (doctor, export-{context,requirements}, create-pr, settings show/set,
sprint activate/close/remove/set-current, ticket add/remove).
When designing a new flow: the TUI surface is mandatory; a CLI surface is optional and only earns its place when the flow is one-shot, scriptable, and doesn't need interactive input.
3. Predictable Patterns
| Pattern | Convention |
|---|---|
| CRUD-style inspection | <noun> list/show <id> |
| One-shot mutation | <noun> remove <id> |
| Force/overwrite | -f, --force |
| Dry run | --dry-run |
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.

designer is an agent published in the GitHub repository lukas-grigis/ralphctl (23 stars, last pushed 3d ago), licensed MIT. It adds 75 tokens to every session and 3,002 once invoked, about $0.0004 per session on Opus 5. 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.
