Quality

Content

82%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 highly actionable with executable commands and a clear connection state machine, well-organized under clean headers, with only minor conciseness and structural-cross-reference issues.

Suggestions

Trim the introductory paragraph explaining what Twelve Data is, since the frontmatter and Overview already convey it.

Fix the broken step cross-references: define a 'Step 1 / Step 2' structure or replace 'Skip to Step 2' and the lone '1b' header with consistent labels.

Merge the near-duplicate 'Searching for actions' and 'Popular actions' sections to remove redundancy.

DimensionReasoningScore

Conciseness

The body is mostly efficient with copy-paste commands and a tight flags table, but the opening paragraph explaining what Twelve Data is ('a service that provides real-time and historical market data...') and minor restatements could be trimmed.

4 / 5

Actionability

It provides fully executable, copy-paste-ready commands for install, login, connection ensure, polling, action list/run, and proxying, plus a complete flags table covering the common cases.

5 / 5

Workflow Clarity

The connection workflow has an explicit state machine (READY/BUILDING/CLIENT_ACTION_REQUIRED/CONFIGURATION_ERROR) with polling and a re-check feedback loop, but cross-references like 'Skip to Step 2' and a '1b' header without a '1a' create minor navigation gaps.

4 / 5

Progressive Disclosure

No bundle files exist, so all content is inlined, but it is well-organized under clear section headers (Overview, Authentication, Connecting, Searching actions, Proxy, Best practices); the 'Searching for actions' and 'Popular actions' sections are slightly redundant.

Description

62%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 answers both what and when with an explicit trigger clause and third-person voice, but its action list is generic and the trigger phrasing ('Twelve Data data') is awkward and narrow.

Suggestions

Replace generic verbs ('Manage data, records, and automate workflows') with Twelve Data's concrete capabilities, e.g. 'Fetch real-time and historical market data, forex pairs, crypto prices, and technical indicators.'

Broaden the trigger clause to natural phrasings users actually say: 'Use when the user needs market data, stock/forex/crypto prices, technical indicators, or Twelve Data API access.'

Avoid the redundant 'Twelve Data data' wording.

DimensionReasoningScore

Specificity

It names the domain ('Twelve Data integration') and lists actions ('Manage data, records, and automate workflows'), but those actions are generic and do not reflect Twelve Data's concrete capabilities (time series, forex, crypto, indicators) shown in the body.

3 / 5

Completeness

Both 'what' ('Twelve Data integration. Manage data, records, and automate workflows') and 'when' ('Use when the user wants to interact with Twelve Data data') are present and explicit, but the trigger clause is narrow and could be more specific.

4 / 5

Trigger Term Quality

It includes the brand keyword 'Twelve Data' in an explicit 'Use when' clause, but misses the natural task phrases a user would say ('market data', 'stock prices', 'forex', 'crypto', 'real-time data') and the phrase 'Twelve Data data' is redundant.

3 / 5

Distinctiveness Conflict Risk

Naming the specific service 'Twelve Data' gives it a clear niche with minimal conflict risk, but the generic 'manage data, records, automate workflows' phrasing could overlap with other data-integration skills.
