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 | $0.00137 | $0.01676 |
| Opus 5 | $0.00068 | $0.00838 |
| Sonnet 5 | $0.00027 | $0.00335 |
| Haiku 4.5 | $0.00014 | $0.00168 |
Grade A, and why
readout 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 2d 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 — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Readout
A readout turns an investigation into a durable HTML document someone can read weeks later without any of the original context. It starts one of two ways:
- Snapshot mode — invoked mid-conversation ("write this up"): the conversation's accumulated findings are the source material.
- Research mode — invoked fresh ("/readout on how github webhook events are processed in the server"): there is no conversation to mine, so the investigation itself is part of the job.
Either way, invoking this skill is a side task. Your job as the main agent is to sharpen the scope, launch a child agent with a good brief, and get out of the way — the child does the mining/research and the writing, keeping that (often large) work out of your context window.
Orchestrator workflow
1. Sharpen the scope — ask before launching
A vague brief produces a vague document. Before launching you should be able to list the specific questions the document will answer; if you can't, interview the user first:
- Ask 2–4 targeted questions, offering concrete options rather than open prompts — take a quick look at the code or topic first so the options are real (subsystems, entry points, competing concerns). For "/readout on how github webhook events are processed": which direction matters — inbound triggers, post-back, or both? a current-state reference or a gotcha hunt? which repo(s)?
- Always pin down depth and audience: high-level orientation vs. deep mechanics with line-level grounding; personal notes vs. shared with the team.
- Respect a shrug. "Just a high-level overview" is a valid answer — record it in the brief and move on rather than interrogating. Even then, try to extract the two or three questions the reader most needs answered; specificity is what makes a readout useful.
- Skip the interview when the scope is already specific — a snapshot of a focused conversation, or a precise research request, needs no questions. In snapshot mode the conversation usually supplies the questions; ask only when the invocation is ambiguous about which threads to include.
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

readout is a skill published in the GitHub repository warpdotdev/common-skills (413 stars, last pushed 2d ago), licensed MIT. It adds 137 tokens to every session and 1,676 once invoked, about $0.0007 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.
