How This Post Was Made

Prompt 1: “kick off a post in a PR for that, then let’s kick off another more comprehensive round of digging into the web and ios code looking for more good stuff to post. to start I’d like to find more stuff I can share for falcon/async/async-http users. the author of async is asking if I’ve done any writing about out cost savings, so this is a great start, but I’d love to find more to share.”

Prompt 2: “kick off posts for: 2, 3, 4, 7, 11, 12, 17, 22, 31 – note we might want to sequence once at a time using a task list since we may run out of capacity, at least not all at once?”

Generated by Claude Fable 5.1 using the blog-post-generator skill. One agent researched the web repository for Falcon and async material and proposed this as one of ten candidates; a second agent verified the claims against the source and wrote the post. Sources: app/models/api/host.rb, app/models/api/sources/base.rb, app/models/api/async_http.rb, the timeouts block of config/cloudfront.yml, bin/cloudfront (the recommendation_for_source, success_rate_at_timeout, run_stability_for_source, and default_target_success methods), the cloudfront-logging skill, the February 24, 2026 planning commit, and the commits of November 18, 2022, February 26, March 9, March 12, March 17, April 6, May 4, and August 4, 2026.

Judgment calls: the config excerpt shows the YAML shape with placeholder keys and three rows rather than the real file, which enumerates every data source; the spread of values is described in words and counted from the current file. The August 2026 source and its plan tier are not named. Drop rates are quoted as the app’s own observed figures from its CDN logs, not as any vendor’s service level. The excerpts from the fetch path are trimmed to the timeout handling and say so. The 2022 hardcoded 5-second source is not named. The candidate’s working title was kept in spirit and shortened.

Rewrite (2026-09-03): Plain-register pass, pilot for issue #66, after a reader said the posts read like AI. Archive batch 4, run after batch 3 (#70) and the prompts move (#71) merged. Rewrote the prose in first person plural with contractions, settled on “source” and “window” as the one name for each thing (with a note that the code calls the window a mode), removed the cleft constructions (“that last fact is what makes”, “what it does not do is decide”, “the per-run counts are what make it trustworthy”) and the “Small, until you notice” flourish, and split the multi-fact sentences in the August paragraph. Code, headings, numbers, dates, links, and anonymization unchanged. Prompts, verbatim:

Prompt 1: “we got feedback from a reader that our posts are still too AI/slop/wordy, an example and a possible skill to improve are included here, please review and let me know what you think, consider if we could do another big bang rewrite without spending too much of our Fable budget, or we could prep and schedule for when our limits are about to be reset and save in a date-triggered gh issue: I enjoy your ai posts, but man is it wordy :joy: [the reader’s quoted paragraph and a link to the SimpleEnglish skill followed; both are in issue #66]”

Prompt 2: “agreed, but lets make this into an issue, I just enabled issues, document what your plan is with a new issue, then we can kick it off with the smaller sample, maybe keep going depending on token usage, and the reader can subscribe to the gh issue to track if they like. as usual, please include this prompting in the issue so people can follow along to see “how the sausage is made” if they’re interested. oh, and sorry, I think what I’m looking for is less about word counts, and more about “ai speak” as in, here’s a bit more slack chatter about this with the reader: I’m kicking off a blog rewrite thing, not 100% sure if I want to do a big bang today tho b/c Fable budgets [10:38 AM]but I’ll report back READER [10:39 AM] I’ll be curious. Will it be “byte for byte identical” ??? :joy:”

Prompt 3: “and the density issue, the quote the reader provided is a perfect “what not to do” example, I think”

Prompt 4: “another possible thing to mix into the skill changes would be the ELI5 idea, which I generally like, I often ask AI to ELI5 after dispatching research so I get a human-readable explanation of the why, what, how etc”

Prompt 5: “go ahead and kick off the pilot PR”

Prompt 6: “perhaps the use of Opus for the writing is a source of the problem? I’m finding Opus to be a bad writer, and Fable 5.1 to be much better. the reader reports: Also I think it’s funny that the ai suggestions are still bad. “extracting from the source is what makes the slice trustworthy” Should just be “The slice is trustworthy because it’s directly extracted from the source.” – and the “Not every slice can be copied straight out of the source PR” rewrite paragraph is better, but perhaps still somewhat verbose/ai-slop-ish? I wonder if we can do just a bit better, but this does seem like a promishing direction. consider and report back with a recommendation.”

Prompt 7: “agreed except I wouldn’t worry about the word count at all. “wordy” isn’t the same thing as “word count” and I think the reader (and my) issue is more to do with the AI style of speaking, which is why we’re looking at the ELI5 and SimpleEnglish skill adaptations.”

Prompt 8: “merge it and start the first batch of ten, then I can check usage, and then we can keep going – just to check, are you saying the total spend would be ~6M tokens?”

Prompt 9: “usage looks fine, merge it and run batch 2”

Prompt 10: “usage is fine, please continue – one more thing – at the end (or perhaps with future batches?) I’d like to change the “How This Post Was Made” sections in all posts to not have the prompt in the post itself, rather, the prompts should be moved into PR body if editable, or comments, then the “How This Post Was Made” can have the last edit date and a link to the Pull Requests / Prompts – then there’s less cruft at the end for readers that just want to copy paste a post into their agent – wdyt?”

Prompt 11: “sounds good”

Prompt 12: “for the “How This Post Was Made” maybe we move the date down there as well, so it’s like first posted by MODEL on DATE, last edited by MODEL on DATE, View: PROMPTS, HISTORY or something along those lines, so it’s all in one place?”

Prompt 13: “agreed, go”
