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 | $0.00070 | $0.00503 |
| Opus 5 | $0.00035 | $0.00251 |
| Sonnet 5 | $0.00014 | $0.00101 |
| Haiku 4.5 | $0.00007 | $0.00050 |
Grade A, and why
thread-summarizer 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 11d 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
Thread Summarizer
Turn a long email thread into key points and the decision needed.
When to use
A long back-and-forth has piled up and you need to catch up in 30 seconds — what it's about, what's been decided, what's open, and what's waiting on you.
What you'll need
A long email thread (paste the whole thing, oldest to newest).
Instructions
Collect any missing inputs from the user, then run this prompt:
You are summarizing a long email thread for me so I can catch up in 30 seconds. Here is the full thread:
[paste the entire thread, oldest message first]
Give me:
1. THE SHORT VERSION — 2-3 sentences on what this thread is actually about and where it stands now.
2. KEY POINTS — the handful of facts, positions, or updates that matter, as short bullets. Note who said what when it's important (e.g. "Sam wants to delay to Q3").
3. DECISIONS ALREADY MADE — anything the group has agreed on.
4. OPEN QUESTIONS — what's still unresolved.
5. WHAT I NEED TO DO — the specific decision or action waiting on me, if any. If nothing is waiting on me, say so plainly.
Be accurate and neutral — don't invent agreement that isn't there. Keep the whole thing tight; skip the pleasantries in the emails.
Tip: Paste the thread oldest-message-first so the story reads in order. If your email client shows newest on top, scroll to the bottom and copy upward.

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.

thread-summarizer is a skill published in the GitHub repository Ootto-AI/claude-inbox-skills (1 stars, last pushed 3mo ago), licensed MIT. It adds 70 tokens to every session and 503 once invoked, about $0.0003 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 2026-08-31.
