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.

What it costs to keep this loaded
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 | $0.00179 | $0.01757 |
| Opus 5 | $0.00089 | $0.00879 |
| Sonnet 5 | $0.00036 | $0.00351 |
| Haiku 4.5 | $0.00018 | $0.00176 |
Grade A, and why
atprotoing 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.
How it starts
The opening of the file, as written. The whole thing — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ATProtoing
Reads the atmosphere from sources that stay up when Bluesky PLC's AppView does not. On 2026-08-16 the AppView timed out and Jetstream returned 503 while PDSes and Constellation served every request — this skill is built around that split.
Invoke
python3 <skill>/scripts/atproto.py <command> [--json]
Digest output is the default and is what belongs in a transcript. Reach for
--json only when the result will be transformed programmatically; raw records
are large and re-reading them into context defeats the purpose.
| Command | Answers |
|---|---|
feed [actor] [--hours 3] [--html PATH] |
The Following timeline, threaded |
status [--actor X] |
Which layer is broken right now |
interactions <actor> [--hours 8] [--scan 100] |
Who liked/replied/reposted/quoted recent posts |

Replies to a post |

An actor's posts, from their own PDS |
records <actor> <collection> |
Any collection in any repo |
resolve <actor> |
DID, handle, PDS host |
backlinks <target> [--collection C --path P] |
What references a record or account, in ANY lexicon |

lexicons [query] [--hours N] [--others] [--schema NSID] |
Which collections are active network-wide |
Source model
Each read targets the cheapest source that survives independently. Prefer the PDS for anything a repo owns — it is authoritative and had no outage.
| Need | Source |
|---|---|
| Records of a known repo | That repo's PDS |
| Who interacted with a URI | Constellation (constellation.microcosm.blue) |
| handle ↔ DID ↔ PDS, and its history | plc.directory, entryway resolveHandle |
| Which collections are active network-wide | UFOs (ufos-api.microcosm.blue) |
| Search, feed generators, chat | AppView only — no substitute; say so |
feed is the one composite read: there is no AppView-free getTimeline, so it
rebuilds the Following timeline from follows → PLC → each followee's PDS, then
hydrates what the AppView would have inlined — facet byte-ranges to character
ranges, blob CIDs to cdn.bsky.app URLs, quote and parent URIs to fetched
records — and threads the result by reply root. --html writes a self-contained
Preact reader (same components as austegard.com/bsky/thread-reader.html), so a
feed request is one call, not a fan-out the caller re-derives by hand.
Ranking, mutes, and blocks live in the AppView and are absent by construction:
this is the raw follow graph.
What ships with it
8 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.

atprotoing is a skill published in the GitHub repository oaustegard/claude-skills (148 stars, last pushed yesterday), licensed MIT. It adds 179 tokens to every session and 1,757 once invoked, about $0.0009 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.
