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 5.1 | $0.00097 | $0.02005 |
| Opus 5.5 | $0.00039 | $0.00802 |
| Sonnet 5.5 | $0.00019 | $0.00401 |
| Haiku 4.5 | $0.00010 | $0.00200 |
Grade A, and why
ask-claude 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 today.
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 — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Ask Claude
Two questions sound different and are the same question: how should I ask Claude to do this?
- "Users can't sign up." The answer is a way of working (reproduce first, plan or don't, what proves it's fixed) and a prompt that says it.
- "Run rubocop after every edit." The answer is a feature. A line in CLAUDE.md gets followed most of the time. A hook runs every time. Picking wrong means it quietly doesn't happen.
Either way, end with a prompt the user approves before anything runs.

1. look ...... the code and setup the task touches
2. read ...... the docs that apply, fetched now
3. ask ....... only what neither can tell you
4. recommend . the approach, why, and the prompt, shown for approval
5. run ....... here, as written
Two ways this fails. The answer comes from memory, and recommends a feature that's been renamed, or misses the one released last month that fits better. Or the prompt restates the task in more words and adds nothing the agent couldn't have guessed.
1. Look
The task is $ARGUMENTS, or ask for one.
Skim the README, the routes, the area the task names, recent commits there. You're
looking for what the prompt can point at: the file that handles it, the pattern to
copy, the test that covers it, the command that checks it. A prompt that names
app/controllers/registrations_controller.rb beats one that says "the sign-up code".
Check what's already set up too: CLAUDE.md, .claude/settings.json hooks,
.claude/skills/, .claude/agents/, installed skills. An installed skill that already
does the job beats writing a new one, and a hook that already exists changes the
answer.
Stay in the repo and its Claude setup. Don't search Slack, email, or other connected tools for context. Those hold the user's own messages, and a guess built from an old post reads like a fact. If you need something from there, ask.
2. Read the docs
Claude's features change month to month, so don't recommend from memory. Start at the indexes, pick the pages that bear on this task, and read them:
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.

ask-claude is a skill published in the GitHub repository thoughtbot/rails-consultant (29 stars, last pushed yesterday), licensed MIT. It adds 97 tokens to every session and 2,005 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-11-07.
