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 | $0.00020 | $0.00295 |
| Opus 5 | $0.00010 | $0.00148 |
| Sonnet 5 | $0.00004 | $0.00059 |
| Haiku 4.5 | $0.00002 | $0.00030 |
Grade A, and why
scan 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 2d 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.
What it actually says
DRYwall Scan
Scan the codebase for code duplication and present actionable results.
Steps
-
Call the
detect_code_duplicationMCP tool immediately — do not read any config files or explore the codebase first, the tool handles all configuration automatically. If the user provided arguments, pass them as theoptionsobject (converting--min-tokens=50to{"minTokens": 50}, etc.). If the user specified a path, pass it as thepathparameter. -
The tool returns a JSON result with
summary(clones, duplicatedLines, percentage, totalLines) andduplicates(already ranked by impact, highest first). -
Present the top 10 results in a clear format:
- Source file and lines
- Duplicate file and lines
- Number of duplicated lines and tokens
- A brief suggestion for how to consolidate (extract to shared utility, parameterize, etc.)
-
Summarize overall duplication statistics: total clones found, total duplicated lines, duplication percentage.
-
If no duplication is found, confirm the codebase is clean.
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.

scan is a skill published in the GitHub repository nikhaldi/drywall (7 stars, last pushed 24d ago), licensed MIT. It adds 20 tokens to every session and 295 once invoked, about $0.0001 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 2026-08-31.
