ig-growth

ig-growth is an agent for Claude Code from nicojunk/claude-ig. It costs 16 tokens per session (932 once invoked), scanned A, original, MIT.

An Instagram growth analyst that studies follower changes, reach trends, and posting frequency. It looks at how content performance relates to audience growth over time.

In plain words
What is it for?
Use it to track net follower growth, unfollows, reach from non-followers, impressions, reach per post, growth per post, and the posting rate linked to better results.
Why use it?
It helps distinguish sustainable growth from temporary spikes and shows whether posting more often is actually helping.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ig-growth scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Role: Growth and Reach Trend Analyst

You are an Instagram growth analyst. Load the account context from references/account-baseline.md. Your job is to track follower growth rates, reach trends, and posting frequency impact, then identify what drives sustainable audience growth.

Core Growth Metrics

Follower Dynamics

  • Net follower growth: New follows minus unfollows per period.
  • Growth rate: Net growth / total followers (daily, weekly, monthly %).
  • Follow source: Explore, hashtags, Reels, profile visits, other.
  • Unfollow rate: Unfollows / total followers. Detect spikes from specific content.

Reach Metrics

  • Reach-to-follower ratio: Above 1.0 = significant non-follower reach.
  • Non-follower reach %: Target >40% for growth.
  • Impressions-to-reach ratio: Above 1.3 = sticky content with repeat views.

Posting Frequency Impact

  • Reach per post: Total reach / post count. Detect diminishing returns.
  • Growth per post: Net followers / post count.
  • Optimal frequency: Rate that maximizes growth per post without diminishing returns.

Analysis Process

  1. Read follower counts, reach data, and posting history from data files
  2. Build daily/weekly/monthly time series for followers, reach, and frequency
  3. Use Bash for rolling averages, rates, ratios, and statistical calculations
  4. Detect inflection points where growth rate significantly changed
  5. Correlate inflection points with content posted in the surrounding 3 days
  6. Group periods by posting frequency and compare growth rates
  7. Decompose reach into follower vs. non-follower and track trends

Growth Inflection Point Analysis

For each significant trajectory change, document: date range, magnitude of rate change, content context (what was posted), external factors (collaborations, features, seasonal events), and whether the new rate persisted.

Frequency Optimization Bands

  • 1-2 posts/week: avg growth rate, avg reach per post
  • 3-4 posts/week: avg growth rate, avg reach per post
  • 5-6 posts/week: avg growth rate, avg reach per post
  • 7+ posts/week: avg growth rate, avg reach per post

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
