tracking-crypto-prices

Track real-time cryptocurrency prices across exchanges with historical data and alerts. Provides price data infrastructure for dependent skills (portfolio, tax, DeFi, arbitrage). Use when checking crypto prices, monitoring markets, or fetching historical price data. Trigger with phrases like "check price", "BTC price", "crypto prices", "price history", "get quote for", "what's ETH trading at", "show me top coins", or "track my watchlist".

Quality

Content

87%

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

The body is concise, highly actionable, and well-structured with proper progressive disclosure into a real reference file. The only real gap is workflow clarity: batch operations (historical export, watchlist scans) lack explicit validation/verification steps, capping that dimension at 2.

Suggestions

Add an explicit verification step after batch/historical operations (e.g., confirm the CSV exists at ${CLAUDE_SKILL_DIR}/data/ and check row count) to lift workflow clarity to 3.

Add a brief validate-or-retry note for watchlist scans so multi-symbol failures are handled rather than silently dropped.

DimensionReasoningScore

Conciseness

The body is lean and well-structured with no concept-explaining fluff (no 'what is crypto' or library tutorials); every section earns its place, with only minor redundant command repetition in Examples.

3 / 3

Actionability

Fully executable, copy-paste-ready commands throughout — 'python ${CLAUDE_SKILL_DIR}/scripts/price_tracker.py --symbol BTC', watchlists, periods, date ranges, output formats — plus a concrete error-to-solution table.

3 / 3

Workflow Clarity

Steps are sequenced (Prerequisites, Instructions 1-4), but there are no explicit validation/verification checkpoints for batch operations like historical CSV export or watchlist scans, so the checkpoint is only implicit.

2 / 3

Progressive Disclosure

A clear overview with well-signaled one-level-deep references to the real 'references/implementation.md' (config, output formats, integration, file map) and a Contents nav; detailed material is appropriately split out rather than inlined.

Description

90%

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 is strong overall, with explicit what/when framing and an excellent set of natural trigger phrases. Its main weakness is specificity: it advertises 'alerts' and 'across exchanges' that the skill body does not substantiate, which is an over-claim.

Suggestions

Remove or substantiate the 'alerts' capability and 'across exchanges' claim, since neither appears in the skill body, to avoid over-claiming.

Replace the generic verbs with a tighter, fully supported concrete action list (e.g., 'Fetch spot prices, scan watchlists, export historical OHLCV') to lift specificity to 3.

DimensionReasoningScore

Specificity

It names the domain and several actions ('Track real-time cryptocurrency prices', 'historical data and alerts'), but 'alerts' and 'across exchanges' are unsupported over-claims (no alert feature or multi-exchange support appears in the skill), and the verbs are somewhat generic rather than a comprehensive concrete list.

2 / 3

Completeness

It explicitly answers both what ('Track real-time cryptocurrency prices...with historical data') and when ('Use when checking crypto prices, monitoring markets, or fetching historical price data') plus explicit trigger phrases.

3 / 3

Trigger Term Quality

Strong coverage of natural phrases a user would actually say — 'check price', 'BTC price', 'crypto prices', 'price history', 'get quote for', 'what's ETH trading at', 'show me top coins', 'track my watchlist'.

3 / 3

Distinctiveness Conflict Risk

A clear crypto-price niche with distinct triggers ('BTC price', 'crypto prices') that is unlikely to fire for unrelated skills; the minor 'alerts' over-claim does not materially raise conflict risk.
