archive-crawler

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.

Quality

Content

75%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-structured, actionable body with executable file-type handlers, a clear 3-phase workflow anchored by an explicit safety gate, and cleanly signaled cross-references; uniform 4s reflect minor trimming, command-level, feedback-loop, and file-splitting opportunities rather than any real weakness.

DimensionReasoningScore

Conciseness

Mostly lean and assumes Claude's competence: compact gold-filter table, executable file-type snippets, and copy-paste templates with no basic-concept padding; minor trim opportunities (the "What this is" section restates the description, and the manifest is described in Concepts then templated again later) keep it just below a 5.

4 / 5

Actionability

Concrete, executable guidance for the hard cases — mbox parsing via Python mailbox, .docx zipfile/XML extraction, PST magic-byte validation plus readpst — plus copy-paste manifest and brain-page templates; minor gaps (tree-mapping in Phase 1 is described as a step rather than given as commands) hold it at 4 rather than 5.

4 / 5

Workflow Clarity

A clearly sequenced 3-phase protocol with explicit checkpoints: the mandatory scan_paths safety gate (exit if unset), read-before-show filtering, never-re-show manifest check, and per-item status updates; validation is present (so the batch-operation cap at 3 does not trigger), though a validate→fix→retry feedback loop is not strongly emphasized, leaving it at 4.

4 / 5

Progressive Disclosure

Well-organized single file with clear section headers and well-signaled one-level-deep cross-references (convention blockquotes up top, "Related skills" section); the inlined file-type handlers and templates could arguably move into references/ files, which is the minor gap keeping it from 5.

Description

70%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A specific, well-scoped description with concrete actions, strong source-synonym keywords, and a distinctive safety-gate signature, but it lacks an explicit 'Use when...' trigger clause so completeness is capped at 3.

Suggestions

Add an explicit 'Use when...' clause, e.g. 'Use when scanning personal archives in Dropbox, Backblaze B2, Gmail takeout, or local mounts to surface the user's own writing, ideas, and relationships.'

Fold one or two of the natural trigger phrases from the frontmatter triggers list (e.g. 'crawl my archive', 'mine my old files') into the description so the 'when' is explicit rather than implied.

Mention the supported file extensions (.mbox, .pst, .doc/.docx) to round out trigger-term coverage toward a 5.

DimensionReasoningScore

Specificity

Names the domain ("personal file archives (Dropbox/B2/Gmail-takeout/local-mount/hard-drive-dump)") and several concrete actions ("Filters for high-value content", "surfaces it interactively", "REFUSES TO RUN without an explicit gbrain.yml archive-crawler.scan_paths allow-list"); not quite the comprehensive multi-action list of a 5, but clearly above the 1-2-action midpoint.

4 / 5

Completeness

The "what" is clear (universal archivist that filters and surfaces), but there is no explicit "Use when..." clause or equivalent trigger guidance — the "when" is only weakly implied by the source enumeration, so per the rubric cap completeness stays at 3.

3 / 5

Trigger Term Quality

Good natural-term coverage including source synonyms users would say ("archive", "Dropbox", "B2", "Gmail-takeout", "local-mount", "hard-drive-dump") and content nouns ("writing, ideas, relationships"); a few natural terms and file extensions (.mbox, .pst) are missing, so it stops short of a 5.

4 / 5

Distinctiveness Conflict Risk

Clear niche (personal file archives with a high-value/gold filter and a unique allow-list refusal signature) that distinguishes it from sibling ingest skills; minimal conflict risk.
