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 | $0.00101 | $0.01245 |
| Opus 5.5 | $0.00040 | $0.00498 |
| Sonnet 5.5 | $0.00020 | $0.00249 |
| Haiku 4.5 | $0.00010 | $0.00125 |
Grade A, and why
feed-watch 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 — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.
feed-watch: collect → score → drafts → digest
Everything specific to this project — which feed, what counts as an item, the rubric, the
threshold, the labels, the reply template, the copy gate — is in .set/feed-watch.yaml
and the files it names. Read it first: set-feed-watch show prints it resolved.
Iron rules
- Read only. You never post, comment, react, like, share, join, follow, message or send anything, on any source. A human sends every reply.
- Only the declared feeds. Open only the
urlof a declared source and the permalinks of its items. No messenger, notifications, profiles, search, or other groups or pages. - Human pace, one tab. Scroll a screen at a time, wait 2–4 seconds, read what is visible. No parallel requests, no scraper, no JavaScript bulk extraction.
- On trouble, stop and report. No refresh, no retry loop, no workaround for a login wall or a challenge.
0. Preparation
- Ask the user to bring the Chrome window to the front (logged in to the source) and keep it there during the run. Measured: in a background window the feed rendered one item and then only loading placeholders.
set-feed-watch show— sources, caps (max_items_per_run,max_age_days), the item filter file, the rubric guidance file, labels, draft template and blocks.set-feed-watch seen— the ids and text hashes already collected.- Load the Chrome tools in ONE ToolSearch call (see the
claude-in-chromeskill), open one new tab on the source'surl. Apply the source'ssort_hint; if you cannot, say so in the report.
1. Collection
Scroll in small steps. Stop when ANY of these holds, and record which one:
- you reached the newest item already collected, or items older than
max_age_days; - you processed
max_items_per_runitems; - stall: two consecutive scrolls brought no new item — only loading placeholders;
- challenge: a login wall, captcha, verification prompt, or an error page.
A run that collected zero items while the feed showed only placeholders is a stall, never "no new items".
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.

feed-watch is a skill published in the GitHub repository tatargabor/set-core (36 stars, last pushed 8d ago), licensed MIT. It adds 101 tokens to every session and 1,245 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 2026-10-28.
