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 | $0.00223 |
| Opus 5 | $0.00010 | $0.00112 |
| Sonnet 5 | $0.00004 | $0.00045 |
| Haiku 4.5 | $0.00002 | $0.00022 |
Grade B, and why
assay-inventory scanned grade B with 1 finding 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 5d 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
- **MCP servers** — entries under `mcpServers` in `~/.claude/settings.json` What it actually says
/assay-inventory
Enumerate everything on the local machine that Assay can scan.
Usage
/assay-inventory
What this command does
Runs assay inventory. The output is a table with one row per detected item:
- Claude Code plugins — directories under
~/.claude/plugins/with aplugin.json - MCP servers — entries under
mcpServersin~/.claude/settings.json - Hooks — every
PreToolUse,PostToolUse,UserPromptSubmit, etc. - Settings overrides —
permissions.allow/permissions.denygrants
For each item, the table shows name, kind, version (if declared), and source URL (if declared).
This is the input source for /assay-scan: you can pick a target by name from the inventory.
Execute:
assay inventory
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.

assay-inventory is a command published in the GitHub repository chawdamrunal/assay (4 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 20 tokens to every session and 223 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
