# AgentArtifactCorpus (AAC)

Agent configuration artefacts (`AGENTS.md`, `CLAUDE.md`, `.cursorrules`, `.mdc`
rules, system-prompt files) crawled from public GitHub repositories under
permissive licences. AAC underpins the compaction, decomposition, and
classifier experiments in the CIKM 2026 paper *The Compaction Cliff in
Long-Running AI Agent Memory*.

- **Code and reproduction:** https://github.com/searchsim-org/knowledge-triage
- **Datasheet:** see `DATASHEET.md` in the code repository
- **Access:** gated, with a one-page Data Use Agreement (see above)

## Configurations

| Config | Contents | Use |
|---|---|---|
| `corpus` (default) | one row per artefact, with redacted `text` | training / analysis |
| `manifest` | same rows without `text` (hash + metadata) | full index, dedup and opt-out bookkeeping |

```python
from datasets import load_dataset
ds = load_dataset("searchsim/AgentArtifactCorpus", "corpus", split="train")
```

## Schema

Rows are at the **occurrence level**: a template copied across many repositories
appears once per repository, each with its own provenance. `dup_count` and
`is_duplicate` let you deduplicate by content when you need to.

| Column | Type | Notes |
|---|---|---|
| `id` | string | SHA-256 of the artefact content; the dedup key |
| `repo_slug` | string | **anonymised** pseudonym (`anon/<hash>`) |
| `anonymized` | bool | always True: every source repository is anonymised |
| `file_path` | string | path of the artefact within its repository |
| `family` | string | `claude.md`, `agents.md`, `cursorrules`, `copilot`, `system-prompt`, `other` |
| `platform` | string | crawler platform: `claude`, `cursor`, `copilot`, `windsurf`, `continue`, `aider`, `universal` |
| `function` | string | `instruction`, `strategy`, `configuration`, `memory` |
| `authorship` | string | `human`, `template`, `agent`, `hybrid`, `unknown` |
| `specificity` | string | e.g. `project`, `global` |
| `size_bytes` | int | original file size |
| `char_count` | int | original character count (from the crawl) |
| `crawl_timestamp` | string | ISO 8601 crawl time |
| `dup_count` | int | number of occurrences sharing this `id` |
| `is_duplicate` | bool | False on the first occurrence of an `id`, True on the rest |
| `char_len` | int | length of the redacted text (`corpus` config only) |
| `redactions` | int | number of PII/secret redactions applied (`corpus` config only) |
| `text` | string | redacted artefact text (`corpus` config only) |

The `manifest` config carries every in-scope artefact (metadata only, no `text`),
including artefacts whose body is not materialised. The `corpus` config carries
the materialised, scrubbed subset with `text`.

## Anonymity, provenance, and licensing

Source repositories are **anonymised**: every `repo_slug` is a stable pseudonym
(`anon/<hash>`). The `repo_license` column records the upstream SPDX licence
(not identifying). The dataset is distributed under **CC-BY-4.0**; cite the
paper below rather than individual repositories.

## Scrubbing

Every artefact passes these filters (see the code repository's `build_full.py`):

1. **Secret scan** — `gitleaks` / `trufflehog` / bearer-token shapes; any hit drops the file.
2. **PII redaction** — emails, GitHub @handles, internal hostnames, IPs, user paths, and attribution front-matter lines are replaced with `<REDACTED_*>` placeholders.
3. **Anonymisation** — the `repo_slug` is replaced with a pseudonym.

## Opt-out

To have your repository removed, open a data-removal request on the code
repository. Because slugs are anonymised, maintainers resolve the request
through a private map held off-Hub, then publish a new gated revision (and
Zenodo version) with the matching rows removed.
