At a glance

Expert in forecasting, signal detection, and market intelligence.

  • Works in 3 steps: Trend Identification → Trend Forecasting → Trend Impact Assessment
  • Tasks that involve Forecasting and time series
  • SKILL.md covers Purpose, When to Use, Quick Start and Decision Framework, plus 3 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Trend Analyst is an agent skill from majiayu000/claude-skill-registry. Expert in forecasting, signal detection, and market intelligence. Specializes in time-series analysis, social listening, and predictive modeling for business trends.

Its SKILL.md is about 880 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `metadata.json`).

It sits in Data & Analytics, covering Forecasting and time series. The repository describes itself as: Searchable Claude Code skills catalog with source-linked guides and generated registry artifacts. The licence is MIT.

When your agent uses it

  • Tasks that involve Forecasting and time series

Example prompts

  • “/trend-analyst”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Trend Identification
  2. Trend Forecasting
  3. Trend Impact Assessment

What it can do on your machine

Read from SKILL.md and the folder at commit 2d14a69. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Trend Analyst loads about 883 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 364 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~45
When it runs · the whole SKILL.md, loaded when a task matches
~883

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Expert in forecasting, signal detection, and market intelligence. Specializes in time-series analysis, social listening, and predictive modeling for business trends.

Trend Analyst

Purpose

Provides expertise in identifying, analyzing, and forecasting trends in markets, technology, and business environments. Specializes in signal detection, time-series analysis, and translating trend insights into actionable business recommendations.

When to Use

  • Identifying emerging trends in technology or markets
  • Analyzing time-series data for patterns and forecasts
  • Monitoring social signals for trend detection
  • Evaluating trend strength and longevity
  • Creating trend reports and forecasts
  • Distinguishing signals from noise in data
  • Assessing market timing for product/feature launches
  • Building early warning systems for industry changes

Quick Start

Invoke this skill when:

  • Identifying emerging trends in technology or markets
  • Analyzing time-series data for patterns and forecasts
  • Monitoring social signals for trend detection
  • Evaluating trend strength and longevity
  • Creating trend reports and forecasts

Do NOT invoke when:

  • Analyzing static datasets → use data-analyst
  • Conducting market research → use market-researcher
  • Competitive analysis → use competitive-analyst
  • Financial time series specifically → use quant-analyst

Decision Framework

Trend Analysis Task?
├── Emerging Trends → Signal detection + weak signal analysis
├── Trend Strength → Momentum analysis + adoption curves
├── Forecasting → Time-series models + scenario planning
├── Market Timing → Diffusion models + leading indicators
├── Social Listening → Sentiment analysis + volume tracking
└── Technology Trends → Hype cycle positioning + maturity assessment

Core Workflows

1. Trend Identification
  1. Define domain and scope for trend scanning
  2. Identify data sources (search trends, social, patents, publications)
  3. Set up monitoring for volume and velocity changes
  4. Detect anomalies and emerging patterns
  5. Validate signals across multiple sources
  6. Classify by trend type (fad, megatrend, seasonal)
  7. Document with evidence and confidence level
Show full SKILL.md (161 more words)Show less
2. Trend Forecasting
  1. Gather historical data on trend indicators
  2. Clean and prepare time-series data
  3. Select appropriate forecasting model
  4. Fit model and validate with holdout data
  5. Generate forecasts with confidence intervals
  6. Create scenarios (optimistic, base, pessimistic)
  7. Update forecasts as new data arrives
3. Trend Impact Assessment
  1. Identify trend with potential business impact
  2. Analyze trend drivers and sustainability
  3. Map affected industries and segments
  4. Assess timing using adoption curves
  5. Evaluate competitive implications
  6. Recommend strategic responses
  7. Establish monitoring for trend evolution

Best Practices

  • Triangulate signals across multiple independent sources
  • Distinguish between leading and lagging indicators
  • Quantify uncertainty with confidence intervals
  • Consider base rates when evaluating trend claims
  • Update forecasts regularly with new information
  • Separate trend identification from trend prediction

Anti-Patterns

  • Recency bias → Consider historical context and cycles
  • Confirmation bias → Seek disconfirming evidence
  • Single-source reliance → Validate across multiple sources
  • Overfitting forecasts → Use holdout validation
  • Ignoring base rates → Most predicted trends don't materialize
