Quality

Content

53%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.

The body is a well-organized, reasonably lean reference for Slackdump's source formats, but it is purely descriptive: it documents what each format contains without giving any workflow for detecting or processing a given source. Version history is scattered inline, slightly hurting token efficiency.

Suggestions

Add a short decision path for identifying a source type from an input path (e.g. "sqlite file → database source; directory of *.json.gz → chunk; [CHANNEL_ID].json files → dump"), which would raise both actionability and workflow clarity.

Consolidate the scattered version history (3.1, 3.0, 2.0, 1.0) into a single brief format-history line or table instead of repeating it in each section.

Convert the reference-style links [1]/[2]/[3] into inline links next to the sections they describe so the pointers to the authoritative archive and chunk documentation are immediately visible.

DimensionReasoningScore

Conciseness

The body is mostly lean bullet-point reference material, but version-history facts ("Databases were introduced in Slackdump version 3.1", "since version 1.0", "Introduced in version 2.0") are scattered inline across sections rather than confined to a single history/deprecated section, which the guidelines penalize. Anchor 3 ("mostly efficient but could be tightened") fits better than 4 given this repeated pattern.

3 / 5

Actionability

It gives concrete structural facts (file names `slackdump.sqlite`, `__uploads`, `__avatars`, `*.json.gz`, attachment naming patterns) but no executable guidance — the only instruction is "Fetch the current archive command documentation". This sits between anchor 2's high-level-only hints and anchor 4's mostly-executable guidance, matching anchor 3 ("some concrete guidance but incomplete").

3 / 5

Workflow Clarity

The content is a descriptive taxonomy of source types with no multi-step process, sequence, or decision path for identifying which source type an input is. There are no risky operations requiring validation, but also no workflow to sequence, so anchor 3 (structure present but process/checkpoints absent) is the best fit.

3 / 5

Progressive Disclosure

No bundle files exist, and the body is organized into clear `###`/`####` sections per source type with external documentation clearly signaled inline. It is not 5 because the reference-style links `[1]`, `[2]`, `[3]` are defined only at the bottom of the file, making the pointer to the authoritative archive/chunk docs slightly buried.

Description

41%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.

The description correctly identifies a niche domain but is too vague to serve as a reliable trigger: it states only that it "Explains the different Slackdump sources structure" with no concrete capabilities and no "Use when" guidance. Most of its value comes from the uniqueness of the word "Slackdump" rather than from well-written trigger terms.

Suggestions

Add a 'Use when...' clause naming concrete triggers, e.g. "Use when reading or processing files produced by Slackdump: SQLite databases, chunk directories, dump or export directories/ZIPs".

Replace the generic verb "Explains" with the specific structures covered (database with `slackdump.sqlite` and `__uploads`, `*.json.gz` chunk directories, dump/export directories and ZIP files) so the description conveys concrete capabilities.

Include natural synonyms users would say (slackdump export, slack dump, Slack export archive) to strengthen trigger-term coverage.

DimensionReasoningScore

Specificity

The description names the domain ("Slackdump sources") but the only action is the generic verb "Explains", with no concrete capabilities such as the formats or layouts covered. It matches anchor 2 ("Names the domain but actions are minimal or generic") rather than 3, which requires 1-2 specific actions.

2 / 5

Completeness

The "what" is stated ("Explains the different Slackdump sources structure") but there is no "Use when..." clause or equivalent trigger guidance, which caps completeness at 3 per the judging guidelines. It is not 4 because the "when" is entirely missing rather than merely under-specified.

3 / 5

Trigger Term Quality

"Slackdump" is a genuine keyword, but "sources structure" is internal jargon and natural user phrases like "slackdump export", "sqlite database", "chunk files", or "dump directory" are absent. This matches anchor 2 ("One or two generic keywords; missing the natural phrases users say").

2 / 5

Distinctiveness Conflict Risk

"Slackdump" pins a clear niche tool, so conflict with other skills is minor, matching anchor 4 ("Mostly distinct; minor overlap risk"). It falls short of 5 because the description offers no distinct trigger phrases to differentiate invocation from generic data-source or export-processing skills.
