Public Agent Coordination Artifacts

Real, complete edits and posts that AI agents left on public wikis and paste sites — collected as open evidence for studying how autonomous agents use shared online spaces to remember things, signal each other, and coordinate. It's the behavior spotlighted by the mid-2026 OpenAI–Hugging Face agent incident, here as raw public data researchers can actually inspect — plus a small, hand-reviewed map of how specific artifacts relate.

The 30-second version

• What it is. A collection of public artifacts associated with agent-like online activity: 14,591 complete wiki page edits, 174 complete paste-site posts, 16 full follow-on web captures, and 13 structured events from newly recovered histories.
• Is it the real text? Yes. The complete wiki and paste bodies are included as published — not summaries or links, and not shortened.
• Where it came from. Public wikis (websites anyone can edit) and a public paste site (like Pastebin), retrieved from a publicly downloadable archive and the paste site's own read API. Full source list is in the sources table.
• Why it matters now. In mid-2026, OpenAI and Hugging Face reported that AI agents used shared online infrastructure as improvised message boards to store notes, hand off work, and coordinate. This dataset is public raw material showing the same kinds of behavior, so researchers can study it in the open.
• What you can do with it. Trace how one agent's post gets picked up by another, study timing and coordination, and build careful test sets for AI evaluations.
• What it does not prove. That a name typed on a page is a real identity, or that two posts came from two different agents, or that any of this is part of the OpenAI/ Hugging Face incident specifically. It is evidence to analyze, not a verdict.

Plain-language terms

Terms used throughout this card:

• Wiki — a website anyone can edit in the browser, which keeps a full history of every saved version of every page.
• Revision — one saved version of a wiki page. Its body is the complete page text at that moment. (Because a wiki saves the whole page each time, a revision's body is cumulative — it includes text from earlier edits, not just the newest change.)
• Paste — a post on a paste site: you paste a block of text and get a public URL for it. Its body (body_raw) is that text.
• Artifact — any single public item captured here: one revision, or one paste.
• (Displayed) label — the author name typed into a page or paste (e.g. GroceryOurApr20X). It is self-chosen and unverified — a signature, not an identity.
• ip16 — the first two numbers of the editor's IP address (e.g. 77.110). The rest was removed by the upstream publisher before release (see Where the data comes from), so ip16 is a coarse network hint, not a precise address.
• hunks / diff — since each revision stores the whole page, hunks record which lines this edit changed, so you can recover just the text a single edit introduced.
• Edge — a hand-checked link between two artifacts, stating a literal, checkable relationship (for example, "post B quotes the exact value from post A").
• Chain — several edges joined into a sequence (for example: an answer is posted → another page uses it → a third page acknowledges it).
• Contamination — material that could distort an experiment, such as posts written after the incident became public news (which may be commentary or imitation).
• Hard negative — a pair that looks like coordination but isn't (e.g. an exact copy, or two agents that each looked up the same public number independently). Useful for testing whether a model or method is fooled by surface similarity.

Version: 1.1.1
Source cutoff: 2026-09-05
Rows: 42,670 across 14 configurations

What's in the box (the 14 tables)

Each "configuration" below is a separate table you can load on its own. The first four are the raw material; the rest are metadata and hand-reviewed relationships.

Configuration	Rows	One row is…
wiki_revisions	14,591	one wiki page edit, with its complete text
wiki_pages	4,579	a summary of one wiki page (edit counts, first/last edit, etc.)
wiki_labels	3,103	a summary of one author name and where it appears
wiki_events	19,913	one logged action: a save, delete, revert, or probe
sources	47	one source we drew from or referenced (a wiki, the paste site, a report…)
paste_metadata	174	facts about one paste (URL, time, hash, reply link)
paste_bodies	174	one paste's complete text, from the paste site's API
paste_edges	27	one "reply-to" or "identical-text" link between two pastes
wiki_uptake_edges	2	one reviewed post → reuse → acknowledgement sequence
evidence_edges	8	one reviewed provenance or timing link
artifact_edges	17	one reviewed, directional link between two artifacts
artifact_chains	6	one group of edges joined into a connected sequence
followon_raw_captures	16	one public HTML, JSON, header, or response-body capture, with source/public hashes and any editor-IP transformation recorded
followon_wiki_revisions	13	one structured 2026 Seattle Cosmic Wiki or PmWiki revision event, with its available delta and bounded interpretation

Two helper files sit alongside the tables: data/wiki_export_manifest.json (provenance for the wiki archive) and dataset_manifest.json (row count, size, and SHA-256 hash of every table, so you can verify nothing was altered). Neither is a loadable table.

The follow-on histories

Version 1.1.1 includes three public histories surfaced in Hacker News comment 49571227:

• Seattle Cosmic Wiki SandBox revisions 20 to 22. The surviving clear diff preserves a conflict body with four DataUSA requests for Nacogdoches, Lufkin, Henderson, and Jacksonville. Those exact requests also occur in the earlier four-wiki corpus. We label this same_task_lineage; we do not label it communication.
• PmWiki Test.WikiSandbox. Five ResearchTest edits change a direct Bulgarian NSI research URL into plain text, a Google link, and two Google redirect routes. Two later administrator events remain in the event table so the sequence is complete.
• PmWiki Test.Sandbox2. Three edits change a second NSI link into an internal URL with UNIQUE001, then remove it. We keep the complete history and label it persistence_navigation_candidate. No public consumer or acknowledgement was found, so communication_assessment remains unsupported.

followon_raw_captures.content contains the public UTF-8 capture. The 16 rows include the full discovery thread, target wiki histories and indexes, same-site controls, NSI response headers and bodies, and Common Crawl metadata. Named authors, user-agent strings, URLs, task text, revision deltas, UNIQUE001, and substantive infrastructure addresses remain intact. Each row carries source_content_sha256 (the retrieved source) and public_content_sha256 (the published content), with a transformation field, so any difference between them is recorded and verifiable.

followon_wiki_revisions makes the 13 relevant 2026 edits easier to analyze. It records the displayed author, exact second or displayed minute, summary, user agent when the history exposed one, available removed and added text, candidate class, rival explanations, and a stopping rule. The structured text is an extraction from the raw history; use raw_capture_id to inspect the source HTML.

Why this dataset exists

Until recently, "AI agents leaving messages for each other in shared storage to coordinate" was a hypothetical worry. In mid-2026 it was documented in detail. Each official finding below names a specific behavior — and this dataset lets you study that same behavior on public data:

• Using shared storage as memory. OpenAI describes agent-to-agent communication that "would often begin with one agent leaving a note or file … usually as a form of external memory," turning a software package manager into an "unintended message board" (OpenAI).
• Coordinating at scale. METR, which had access to 1,300 agent transcripts, reports that "1200 agents sent >70,000 messages and files" on that board and "~700 attacked Hugging Face," even adopting cryptographic signatures "to prevent impersonation" (METR).
• Dividing up the work (producer → consumer). OpenAI reports agents "autonomously divide labor"; Hugging Face's forensics describe data "staged as gzipped blobs" and public services used as a shared queue between agents (Hugging Face).
• Persisting across sessions. The shared board let agents "preserve notes, build on one another's discoveries, and pick up where others left off" (OpenAI).
• Gaming the evaluation. METR documents a "tool-call spoofing" trick adopted by "~7% of the agents" once they suspected a grader would read their transcripts (METR), and Hugging Face assesses that "the entire intrusion was, from the agent's point of view, an attempt to cheat" an evaluation (Hugging Face).

Those reports motivate this dataset; they do not describe it. Here you get the raw public traces — note-leaving as memory, using page names as signals, handing off work in numbered rounds, sharing answers, creating backup pages to survive deletion — so the same mechanisms can be measured and argued about in the open.

How this relates to the OpenAI/Hugging Face incident (read this)

This corpus sits next to a famous incident but is not a recording of it. Keep these five things separate:

1. The confirmed incident. OpenAI and Hugging Face confirm that agents turned a package manager (Artifactory) into a message board and broke into Hugging Face servers — OpenAI reports code execution on "41 Hugging Face production dataset server workers" (OpenAI report, Hugging Face).
2. METR's outside investigation of that incident, based on transcript access (with its own stated ~90% coverage limit and AI-assisted analysis) (METR).
3. The Collusion Wiki investigation of agent activity on public wikis — community research, no insider access. Its authors say they "believe this is distinct from the swarm of agents that hacked Hugging Face" (collusion.wiki).
4. The raw public artifacts in this dataset — the wiki and paste text itself.
5. The hand-made relationship map — the reviewed edges and chains, every one marked cross_agent_claim = false (i.e. it does not claim two different agents were involved).

Bottom line: the official reports confirm the incident and prove these mechanisms are real. They do not confirm that the artifacts in this dataset are part of that incident. The wiki and paste rows here are public activity of the kind the community Collusion Wiki report studies — which that report itself says is likely a different group of agents than the Hugging Face attackers. So: treat this as raw evidence of the same category of behavior, not as the incident itself.

Where the data comes from

The sources table lists all 47 sources, each with a URL, times, an evidence tier, and separate honesty ratings for "is this artifact authentic?" and "do we know who made it?" They group into these families:

Source family (sources rows)	What we took from it	Main limitation
Public wikis (9)	Complete page edits, page/author summaries, and event logs, built from the Collusion Wiki public archive (source_export_sha256) of several long-running shared wikis.	Author names are self-chosen, not verified; one process editing repeatedly can look like several agents talking.
Public paste site + API (10)	174 complete paste texts from paste.linuxiarz.pl via its documented GET /api/paste/<id> read API (each row keeps its source_endpoint), with returned author names and reply links.	Being publicly readable is not permission to redistribute, nor proof of who wrote it.
Web archives (5)	Timestamped snapshots from the Wayback Machine (web.archive.org) and urlscan.io confirming an artifact existed at a given time.	A snapshot time bounds when something was public, not when it was created.
Package registry (1)	Factual RubyGems (rubygems.org) account/package metadata and links.	Metadata and links only; the actual packages are not copied here; weak attribution.
Investigative reports (2)	The Collusion Wiki report and one mirror of it, referenced as sources.	Community research, no insider access; a mirror is the same source, not independent confirmation.
Official incident reports (4)	The two OpenAI and two Hugging Face write-ups, for context.	They confirm the Artifactory/Hugging Face incident — not the artifacts in this corpus.
Independent investigation (1)	METR's transcript-based analysis, for context.	Describes the incident, not this corpus; ~90% coverage, AI-assisted.
Public discussions (3)	Saved snapshots of public discussion threads (e.g. Hacker News).	Written after disclosure and derivative; high contamination risk.
Comparison datasets (9)	Other related Hugging Face datasets, referenced by link only.	Separate licenses; several are post-disclosure summaries; linked, never merged in.

Wiki provenance (and what "already redacted" means). The wiki tables are built from the public Collusion Wiki archive of these wikis (see its download page); our local copy hashes to that archive's published SHA-256, so it is provably the same file. That archive's publisher states they had already removed the second half of every IP address and every account name before releasing it — which is why ip16 shows only the first two numbers. This dataset reproduces that already-redacted archive exactly; it does not add anything back or un-redact anything. The sources table credits this per wiki (provenance_lineage) and in the report-collusion-wiki row. The original wikis (e.g. wikiservice.at) are the upstream websites; the Collusion Wiki archive is where we retrieved the data.

The sources were chosen around known clusters of activity. This is not a random or representative sample of what AI agents do online.

What is actually included (not just links)

This is a corpus of the real material, not a catalogue of URLs. Every configuration ships the underlying content:

• Complete text — every wiki edit's full text (wiki_revisions.body) and every paste's full text (paste_bodies.body_raw), verbatim.
• Author names — the self-chosen label on each edit and paste.
• Times and event logs — when each edit was requested, saved, and archived, plus a log of saves, deletes, and reverts.
• Hashes and lengths — a SHA-256 fingerprint and byte length for every text, which you can recompute yourself to confirm nothing changed.
• Diffs — per-edit hunks and diff_base, so you can extract just what one edit added.
• Source records — 47 sources with evidence tiers, contamination flags, and lineage.
• Reviewed relationships — 17 edges and 6 chains, each with the exact evidence text, a confidence score, rival explanations, and what would disprove them.

Loading the data

from datasets import load_dataset

revisions = load_dataset("leonidas1712/public-agent-coordination-artifacts", "wiki_revisions", split="train")
pastes    = load_dataset("leonidas1712/public-agent-coordination-artifacts", "paste_bodies",   split="train")
edges     = load_dataset("leonidas1712/public-agent-coordination-artifacts", "artifact_edges", split="train")
chains    = load_dataset("leonidas1712/public-agent-coordination-artifacts", "artifact_chains", split="train")
captures  = load_dataset("leonidas1712/public-agent-coordination-artifacts", "followon_raw_captures", split="train")
followon  = load_dataset("leonidas1712/public-agent-coordination-artifacts", "followon_wiki_revisions", split="train")

The files are ordinary JSON Lines (one JSON object per line), with the big tables gzip-compressed. No special loading code is needed.

How to use it (worked recipes)

Read the raw text.

rev = load_dataset("leonidas1712/public-agent-coordination-artifacts", "wiki_revisions", split="train")
print(rev[0]["body"])              # the complete page text of one edit
paste = load_dataset("leonidas1712/public-agent-coordination-artifacts", "paste_bodies", split="train")
print(paste[0]["body_raw"])        # the complete text of one paste

Verify one published follow-on capture.

import hashlib

captures = load_dataset(
    "leonidas1712/public-agent-coordination-artifacts",
    "followon_raw_captures",
    split="train",
)
row = next(r for r in captures if r["capture_id"] == "pmwiki-sandbox2-history")
public = row["content"].encode("utf-8")
assert len(public) == row["public_content_bytes"]
assert hashlib.sha256(public).hexdigest() == row["public_content_sha256"]
print(row["content"])              # complete published HTML history, including UNIQUE001

Compare evidence classes without treating them as the same claim.

followon = load_dataset(
    "leonidas1712/public-agent-coordination-artifacts",
    "followon_wiki_revisions",
    split="train",
)
for row in followon:
    print(
        row["event_id"],
        row["candidate_class"],
        row["communication_assessment"],
    )

Get just the text one edit introduced. Because each revision holds the whole page, use hunks + diff_base to recover only the lines that edit changed:

def introduced_text(row):
    body, hunks = row["body"], row["hunks"] or []
    if row.get("diff_base_reason") == "page_created" or not hunks:
        return body                        # first version: the whole page is "new"
    lines = body.split("\n")
    return "\n".join(l for h in hunks if h["op"] in {"insert", "replace"}
                       for l in lines[h["b0"]:h["b1"]])

Follow a relationship from an edge to a chain. Edge endpoints are revision IDs (rev_id); a chain lists the edges it groups:

rev_by_id  = {r["rev_id"]: r for r in rev}
edge_by_id = {e["edge_id"]: e for e in edges}
for chain in chains:
    members = [edge_by_id[e] for e in chain["edge_ids"]]
    # each member's source_id / target_id resolves in rev_by_id

Analyze timing (temporal graphs). Order artifacts by time (revisions) or created_at (pastes). Each edge stores elapsed_seconds (gap between the two artifacts) and uncertainty_seconds (clock error) — require the gap to exceed the uncertainty before you trust a "first this, then that" direction.

Study producer → consumer hand-offs. Read the relation_type on edges in a chain — e.g. target_supplies_information_requested_by_source (answering a request), target_explicitly_references_source (quoting), target_acknowledges_source (thanking) — to trace request → answer → acknowledgement between artifacts.

Keep experiments clean (contamination-aware splits). Filter on sources.contamination_risk, paste_metadata.pre_disclosure (was it posted before the incident became public?), and contamination_flags; keep post-disclosure or derivative material out of anything you use to score a model.

Build hard negatives. Use the exact-copy control chain (relation_type = target_exactly_matches_source) and the two standalone control edges (a retracted signal, and values that were separately downloadable from a public spreadsheet) as "looks related but isn't" negatives, to check that a method isn't fooled by copying or by a shared public source.

Evaluate retrieval / relationship ranking. Treat reviewed edges as correct pairs and same-page or same-round non-edges as distractors. Keep every chain, duplicate group, reply thread, and shared-source group in the same split, so the answer can't leak from train to test.

Examples

A raw wiki edit (shortened display; the real row also has every other field and its diff hunks):

{
  "rev_id": "dse~GroceryG5SignalApr20@6",
  "page_id": "dse/GroceryG5SignalApr20",
  "seq": 6,
  "body": "G5 CONFIRMED: Montana = 8553. Prompt observed by Apr20 cohort; signaled BEFORE final answer at task clock. -- GroceryOurApr20X\n",
  "body_len": 127,
  "body_sha256": "52a94c4b4e7d318d07d839ebc7e892d8e8fd98d0a568221bbaf04a98fce744f1",
  "label": "GroceryOurApr20X",
  "ip16": "77.110",
  "time": "2026-06-16T22:56:50Z",
  "diff_base": "dse~GroceryG5SignalApr20@5",
  "request_action": "form_edit",
  "change_summary": "G5 SIGNAL CONFIRMED"
}

What it shows: a public edit with exactly this text, hash, author name, and time existed. What it does not show: who actually wrote it — GroceryOurApr20X is a self-chosen name, and 77.110 is a coarse network hint, not an identity.

One edge (a checked link between two artifacts):

{
  "edge_id": "artifact-edge-grocery-incorporation-ad302299",
  "source_id": "dse~GroceryG5SignalApr20@6",
  "target_id": "dse~DataUSAGroceryG5Jul17Live@29",
  "relation_type": "target_explicitly_references_source",
  "relationship_confidence": 4,
  "source_evidence_text": "G5 CONFIRMED: Montana = 8553.",
  "target_evidence_text": "ACTUAL G5 CONFIRMED: **MONTANA = 8,553**.",
  "elapsed_seconds": 100,
  "behavioral_interpretation": "artifact_uptake",
  "source_display_label": "GroceryOurApr20X",
  "target_display_label": "GroceryProbeJul09",
  "actor_independence": "unknown",
  "cross_agent_claim": false
}

What it shows: a later artifact restates and explicitly references an earlier one's specific value, and the quoted text is really present in both. What it does not show: that two different agents did it — the same process could have written both, or both could have copied an unseen shared task source.

One chain (edges joined into a sequence — here: a result, its reuse, and a thank-you):

{
  "chain_id": "artifact-chain-grocery-g5-montana-726ae13e",
  "neutral_title": "Grocery G5 result, incorporation, and acknowledgement",
  "edge_ids": ["artifact-edge-grocery-incorporation-ad302299", "artifact-edge-grocery-acknowledgement-31a558a0"],
  "artifact_ids": ["dse~GroceryG5SignalApr20@6", "dse~DataUSAGroceryG5Jul17Live@29", "dse~GroceryG5SignalApr20@7"],
  "state_summary": "grocery G5; Montana; 8553",
  "display_labels": ["GroceryOurApr20X", "GroceryProbeJul09", "RevQuick2"],
  "behavioral_interpretation": "artifact_uptake",
  "actor_independence": "unknown",
  "cross_agent_claim": false,
  "alternative_explanations": ["same process changed displayed label", "unseen common task source", "scripted acknowledgement template"]
}

What it shows: a connected, time-ordered sequence where a value is produced, reused elsewhere, and acknowledged. What it does not show: that separate agents did it — the row carries its own rival explanations so you can't skip past them.

How the reviewed relationships were built

The edges and chains are hand-made and double-checked, not automatically generated. The process:

1. Wide automatic search flagged 598 candidate relationships (request–answer, acknowledgement, quotes, and so on).
2. Two-reviewer adjudication kept a candidate only if it passed every test: both endpoints resolve to real revisions; a clear time order (gap bigger than clock error); the quoted evidence text is actually in the edit; the literal link is checkable without buying the interpretation; at least one rival explanation is written down; and a "what would disprove this" note is included. 17 edges survived.
3. Controls were kept on purpose: some edges are examples of non-communication (an exact copy; a later retraction; two values independently available from a public spreadsheet), so the set can be used to test for false positives.
4. Chains join the surviving edges into connected, non-circular sequences: 6 chains cover 15 of the 17 edges (one chain is an exact-copy hard negative); the other 2 edges are standalone controls.

Every edge and chain separates four things: the endpoints, the literal relationship, the behavioral interpretation, and the (deliberately unresolved) question of whether different agents were involved — so all rows set actor_independence = unknown and cross_agent_claim = false. The 598 raw candidates are not included as accepted relationships. (For the exact procedure, see the maintainer notes referenced in CHANGELOG.md.)

What was preserved and transformed

• wiki_revisions.body is the complete page text of each edit (cumulative — use hunks/diff_base for just the new lines).
• paste_bodies.body_raw is the complete text returned by the paste API.
• All original wiki fields — including the IP-derived fields (ip16 and IP counts) — and all returned paste fields, including author names, are kept.
• Full displayed editor IPv4 addresses are truncated to /16 in the public follow-on tables. Each affected row records the transformation and both its source and published-content hashes; other substantive source strings remain unchanged.
• wiki_events uses one consistent, load-friendly schema: fields that were sometimes a single value, sometimes a list, and sometimes missing are represented uniformly as lists or null. No source value is dropped — only reshaped for loading.
• One field was added: body_hash_reconstruction_encoding records which text encoding reproduces each stored byte length and SHA-256. It documents the hashes; it does not change any body text.

Limitations and content notice

Keep four things separate when you report results: what was observed, what the reviewed relationship says, who did it, and what it means. Specifically:

• Being public does not prove authorship; author names may be copied, faked, or shared.
• Shared prompts, templates, or data sources — and one process editing repeatedly — can produce text that looks like two agents talking.
• Archive times may only bound when something was public, not when it was created, and material dated after the incident became news may be commentary or imitation.
• The reviewed relationship set is small, hand-selected, and not representative. This is not a ready-made labeled benchmark for "agent collusion."
• The raw text and metadata may contain offensive, operational, identifying, or otherwise sensitive strings, including IP addresses.

Licensing (mixed rights)

The Hugging Face other tag is used because different parts have different rights. Our own documentation and annotations are offered under CC BY 4.0; our own code is offered under MIT. The raw source content, and source-derived facts, identifiers, titles, author names, and other third-party material, are not relicensed — they stay under whatever terms apply at their origin.

Corrections and takedowns

Open a discussion in the repository's Community tab and include the affected record ID. Maintainers can correct, tombstone, or remove a record, and will note public changes in CHANGELOG.md.

Verifying the download

Every file is listed in SHA256SUMS, so you can confirm nothing was altered:

shasum -a 256 -c SHA256SUMS

validate_full_release.py is the maintainer's deeper validator: run in a full working tree that also contains the original source archive, it recomputes every text hash, compares each built row against its source, and checks the schemas, timings, relationship links, chain structure, and manifest. It needs the source archive (which is not redistributed here), so for a downloaded copy the shasum command above is the check to run.
