What it does
Dunking Anonymously is an agent skill from oaustegard/claude-skills. Renders a Bluesky post as an anonymised screenshot so its words can be criticised without a link back to whoever wrote them. Blacks out avatar, display name, handle and any at-mentions in declassified-document styling, then emits a PNG and its alt text. Use for anonymous dunk-quoting, "dunk on this without linking it", "screenshot this post with the author hidden", "quote this without naming them", "redact this before I share it", or when a bad take from a small account deserves an answer and its author does not…
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and assets (for example `CHANGELOG.md`, `README.md` and `scripts/dunk.py`).
It sits in Writing & Content. It works with Bluesky. The repository describes itself as: My collection of Claude skills. The licence is MIT.
When your agent uses it
- Anonymous dunk-quoting
- Dunk on this without linking it
- Screenshot this post with the author hidden
- Quote this without naming them
Example prompts
- “dunk on this without linking it”
- “screenshot this post with the author hidden”
- “quote this without naming them”
- “/dunking-anonymously”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit cf49d47. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
bsky.app
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Dunking Anonymously loads about 1.6k tokens when it runs. Until then it costs about 140 tokens; SKILL.md has 903 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Dunking anonymously
A quote-post delivers your whole audience to the original author. For an account with forty followers that is a pile-on whatever your caption said. This renders the post as an image instead, so the words can be quoted without the handle.
Idea from Luis Villa, who built the same feature for himself (https://bsky.app/profile/lu.is/post/3mv6ynbcjr62b). His render greys the identity out; this one blacks it out.
Procedure
python3 scripts/dunk.py https://bsky.app/profile/someone.bsky.social/post/3mv6...Takes a bsky.app URL, an at:// URI, or handle/rkey. Writes <rkey>.png to
the working directory, prints the alt text to stdout, and writes <rkey>.json
holding the source URI for your own records. The source URI stays out of both
the image and the alt text.
| flag | effect |
|---|---|
--redact "phrase" | blacks out a literal phrase, repeatable |
--stamp | adds the rotated REDACTED stamp |
--show-date | prints the post date in the footer |
--out PATH | output path |
--width N | image width, default 1200 |
Then read the rendered PNG, actually open it, and re-run with --redact for
anything in the body that identifies the author. This is the step
that gets skipped.
Deps are PIL and the standard library. DejaVu Mono ships with the container. The API call is unauthenticated, so it needs no token and leaves no trace in anyone's notifications. See README.md for the host fallback and network surface.
Redactions applied
Avatar, display name and handle become black bars. Every at-mention facet in the
body is blacked out, since a mention is a second person's handle and a strong
search key for finding the original. Embedded images, video, link cards and quoted
posts render as [image not shown] and friends rather than being fetched, since
an embedded image can carry a face, a location or a watermark.
Engagement counts are dropped. The date is dropped unless --show-date, because
a date plus one distinctive sentence narrows a search to a single post.
The script cannot strip identity from the post's own words. Bluesky indexes full
post text, so a post naming its author's employer, town or cat stays traceable by
anyone who pastes a sentence into search. --redact is the only defence and it
is manual.
When NOT to use this skill
| situation | what owns it |
|---|---|
| reading, searching or sampling Bluesky content | browsing-bluesky |
| sorting an account list by topic | categorizing-bsky-accounts |
| posting a link with a card preview | muninn_utils.bsky_card |
| bulk-classifying the repliers under a post | muninn_utils.bsky_moderation |
Quote-post public figures and large accounts normally. Anonymising a senator is not protection. It removes the reader's ability to check the source while protecting nobody. The skill is for accounts small enough that attention itself is the harm.
Earned exceptions. Anonymising a large account is earned when the post is being shown as a specimen of a pattern rather than as one person's position, and the handle would pull the thread toward the individual. It is not earned when the reader would reasonably want to verify who said it.
Abandon mid-run when the post cannot be anonymised, meaning the author's
identity is the claim, the text names them, or the render still reads as them
after --redact has eaten half the body. At that point either quote-post it with the
link or drop it. A half-redacted post that everyone recognises is worse than
both, because it performs restraint while doing the pile-on.
Do not use it to launder something you would not say with the link attached. If the criticism only works because nobody can read the original in context, fix the criticism.

Common failure modes
Black bars in the header, author named in the body. The render looks
correctly anonymised and one sentence still says "when I worked at Foo". Signal:
you did not read the PNG, you read the terminal. Open the image every time and
pass --redact per identifying phrase.
Two bars where one phrase should be. A multi-word --redact phrase renders
as separate bars with visible gaps, and word lengths leak. Signal: gaps inside
what should be one black run. Adjacent redacted tokens are meant to merge across the
spaces between them. If they do not, the merge logic in render() broke.
Mentions survive the redaction. Signal: an @handle renders as readable
text. The script reads mention facets, not the @ character, so a post whose
facets were stripped by the client that wrote it has no mention to find. Catch
it by reading the PNG and use --redact "@handle" as the fallback.
no post at at://.... The post is deleted, the author blocks the public
AppView, or the rkey is wrong. Not a transport failure, so refetching will not
fix it.
403 from the AppView. public.api.bsky.app refuses some proxied
environments. The script retries on api.bsky.app, which serves the same
lexicon, and only gives up when both refuse.
Verification
python3 scripts/dunk.py <url> --stampThen open the PNG. Three checks: no handle or display name anywhere in the image, no at-mention rendered as text, and the alt text opening with "Screenshot of a Bluesky post, author hidden:".
A bad success here is a clean-looking render that still identifies its author — every bar in place, and the body naming a workplace or a town. It passes every automated check the script can make, which is why the read-through is part of the procedure rather than a nicety.
Posting it
Attach the PNG in whatever client you post from and paste the printed alt text. It opens with "Screenshot of a Bluesky post, author hidden:" so screen-reader users get the framing that sighted readers get from the black bars.
