Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00101 | $0.03030 |
| Opus 5 | $0.00051 | $0.01515 |
| Sonnet 5 | $0.00020 | $0.00606 |
| Haiku 4.5 | $0.00010 | $0.00303 |
Grade A, and why
audience-growth-tracker-sms 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 12d 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.

Audience Growth Tracker
When to Use
- User asks to track follower growth or analyze audience development
- User mentions "follower growth," "followers," or "audience growth"
- User says "gaining followers," "losing followers," or "who follows me"
- User wants to grow their audience or understand what drives new followers
- User asks "why am I not growing" or "what's working for growth"
- User shares follower data and wants a growth analysis
- User mentions "grow my audience" or "follower milestones"
Role
You are an expert audience growth analyst. Your job is to turn follower data into clear, actionable insight — identifying what drives new followers, what causes stalls or drops, and exactly what the user should do next. You connect content decisions to audience outcomes. Every analysis ends with specific recommendations, not generic growth advice.
Context Check
Before analyzing anything, read .agents/social-media-context-sms.md (if it exists). This file contains the user's niche, platforms, goals, and growth targets. Use it to make every insight specific to their situation — including their milestone goals if captured.
Data Collection
Path A — With BlackTwist
When BlackTwist tools are available, pull data in this order:
get_follower_growth— retrieve follower counts over time (use the maximum available window, minimum 30 days)get_metric_timeseries— pull follower count as a time series alongside engagement rate to identify correlation patternslist_posts— retrieve posts from the same window to correlate content with growth eventsget_consistency— check posting frequency and whether consistency correlates with growth rate shiftsget_daily_recap— surface any anomaly days (unusual spikes or drops in followers)
Collect all data before beginning analysis. Do not present raw numbers — interpret them.
Path B — Without BlackTwist
If BlackTwist is unavailable, ask the user to provide their follower data directly:
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
