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.

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 | $0.00038 | $0.01348 |
| Opus 5 | $0.00019 | $0.00674 |
| Sonnet 5 | $0.00008 | $0.00270 |
| Haiku 4.5 | $0.00004 | $0.00135 |
Grade A, and why
niche-scout 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 3d 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.
How it starts
The opening of the file, as written. The whole thing — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Niche Scout
Evaluate whether a keyword/topic is a profitable KDP publishing niche. Based on the 3-step validation framework from Sean Dollwet, Dale Roberts, and Dave Chesson (175 episodes distilled in Kings of Kindle).

Workflow
Step 1: Amazon Keyword Volume (DataForSEO)
Run the keyword volume script to get Amazon search volume and related keywords:
python3 ~/.claude/skills/niche-scout/scripts/keyword-volume.py "$ARGUMENTS"
This returns:
- Amazon search volume for the seed keyword + 9 variations
- Related keywords with volume (up to 20)
- Use these to assess demand and identify series potential (10-keyword strategy)
Demand threshold: Seed keyword should have 200+ monthly Amazon searches. Related keywords reveal series opportunities.
Step 2: BSR Analysis (Apify Amazon Scraper)
Run the BSR scraper to get Best Seller Rank for top books:
python3 ~/.claude/skills/niche-scout/scripts/bsr-scraper.py "$ARGUMENTS"
This runs two Apify calls:
- Search results — gets titles, prices, ratings, ASINs for top 20 books
- Product details — gets BSR, publisher, categories for top 10
Wait for both to complete (typically 30-90 seconds each).
Step 3: Score the Niche
Apply Sean Dollwet's BSR benchmarks to the scraped data:
| Metric | Target | Scoring |
|---|---|---|
| Books under 5,000 BSR | No more than 5 of top 20 | >5 = too competitive |
| Books under 30,000 BSR | Most or all of top 20 | Sweet spot for new publishers |
| Books under 100,000 BSR | At least 7 of 10 | Minimum viable demand |
| Self-published on page 1 | At least 2-3 | Proves indie can compete |
| Search results count | Under 3,000 | Lower = easier to rank |
Self-published detection signals:
- Publisher = "Independently published" or "Independently Published"
- Price $2.99-$4.99 range
- Keyword-heavy title (exact match of search term)
- Stock/template cover design
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.

niche-scout is a skill published in the GitHub repository cdeistopened/skill-stack (27 stars, last pushed 1mo ago), licensed MIT. It adds 38 tokens to every session and 1,348 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
