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, highly actionable body with executable commands and clear error-recovery guidance. Its weakest points are token efficiency (duplicated command examples between Instructions and Examples) and a dangling reference to a config/sources.yaml file that is absent from the bundle.

Suggestions

Deduplicate the Examples section against the Instructions code block — keep only the commands not already shown (e.g., --min-score, --coins) or fold all examples into references/examples.md, which already exists for this purpose.

Remove the dangling ${CLAUDE_SKILL_DIR}/config/sources.yaml reference from the Resources section (or add the config/ directory to the bundle), since no such file ships with the skill.

Trim the 16-line illustrative ASCII output table to a few representative lines and delete the stray "# 2026 - current year timestamp" meta-comment inside the sample block.

DimensionReasoningScore

Conciseness

The Instructions code block and the Examples section repeat nearly identical commands (default scan, --coin BTC --period 4h, --category defi), and a 16-line illustrative ASCII output table plus a stray "# 2026 - current year timestamp" meta-comment add padding. Mostly efficient with no conceptual over-explanation, but real tightening opportunities place it at anchor 3 rather than 4.

3 / 5

Actionability

Copy-paste-ready commands (e.g., "python ${CLAUDE_SKILL_DIR}/scripts/news_aggregator.py --coin BTC --period 4h", "--format json --output news.json", "--min-score 70", "--coins BTC,ETH,SOL") with concrete prerequisites ("pip install feedparser requests") cover the common cases, matching the fully-executable anchor 5.

5 / 5

Workflow Clarity

A clear 4-step sequence (assess intent, run aggregator, export, present results) plus an error-handling table with concrete recovery guidance (network timeout falls back to cached data; no results suggests relaxing filters). Validation is not inline as an explicit workflow checkpoint, which keeps it at anchor 4 rather than 5.

4 / 5

Progressive Disclosure

The three referenced files (references/errors.md, references/implementation.md, references/examples.md) all exist, are one level deep, and are clearly labeled with their contents. However, "${CLAUDE_SKILL_DIR}/config/sources.yaml" is referenced but no config/ directory exists in the bundle, and the inline Examples section duplicates territory already covered by references/examples.md — minor organization gaps fitting anchor 4 rather than 5.

Description

78%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 strong description with an explicit what-and-when structure and natural trigger phrases. Its main weaknesses are single-action specificity (capabilities like filtering and scoring are left to the body) and one generic trigger phrase that risks overlap with general news skills.

DimensionReasoningScore

Specificity

"Aggregate breaking cryptocurrency news from 50+ sources including CoinDesk, CoinTelegraph, The Block, and Decrypt" names one concrete action with specific sources, but omits other capabilities (coin/category filtering, relevance scoring, JSON export). Matches anchor 3 (1-2 concrete actions, not comprehensive); not 4 because only one action verb is present.

3 / 5

Completeness

Explicitly answers what ("Aggregate breaking cryptocurrency news from 50+ sources...") and when ("Use when needing to monitor crypto market news, track announcements, or find coin-specific updates") with concrete trigger phrases, matching the anchor-5 example structure exactly.

5 / 5

Trigger Term Quality

Natural phrases like "get crypto news", "latest Bitcoin headlines", "DeFi announcements", and "check crypto updates" give good keyword coverage, but common synonyms (e.g., "cryptocurrency news", "altcoin/Web3 updates") are missing. Fits anchor 4 (good coverage, a few natural terms missing) rather than 5.

4 / 5

Distinctiveness Conflict Risk

A clear crypto-news niche with mostly crypto-specific triggers, but the unqualified phrase "scan for breaking news" could overlap with a general news skill. Minor overlap risk with closely related skills fits anchor 4 rather than 5.
