archive-crawler skillA
archive-crawler is agent-read markdown (skill) from garrytan/gbrain: Universal archivist for personal file archives (Dropbox/B2/Gmail-takeout/local-mount/hard-drive-dump). Filters for high-value content (the user's own writing, ideas, relationships) and surfaces it interactively. REFUSES TO RUN without an explicit gbrain.yml `archive-crawler.scan_paths:` allow-list..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# archive-crawler — The Universal Archivist
> **Convention:** see [conventions/quality.md](../conventions/quality.md) for
> citation rules, exact-phrasing requirements when capturing the user's
> reactions, and back-link enforcement.
>
> **Convention:** see [_brain-filing-rules.md](../_brain-filing-rules.md) —
> this skill is **schema-generic**: it reads the user's filing rules from
> the rules JSON instead of hardcoding any specific era / archive layout.
## Safety gate (REQUIRED, no exceptions)
archive-crawler refuses to run unless `archive-crawler.scan_paths:` is
explicitly set in `gbrain.yml`. This is a deliberate safety fence against
the agent over-scoping a scan and ingesting sensitive content (tax PDFs,
medical records, credentials).
```yaml
# gbrain.yml — the allow-list is mandatory
archive-crawler:
scan_paths:
- ~/Documents/writing/
- ~/Dropbox/Archive/
- /mnt/backup/old-letters/
# Optional deny-list inside the allow-list:
# deny_paths:
# - ~/Documents/finances/
# - ~/Documents/medical/
```
If `scan_paths` is empty or missing, the skill exits with:
```
archive-crawler: refusing to run. No `archive-crawler.scan_paths:` allow-list

How to install
mdr add garrytan/gbrain/archive-crawler@v0.1.0mdr add garrytan/gbrain/archive-crawler@sha256:10c529797e1cba75Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
