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 5.1 | $0.00014 | $0.00268 |
| Opus 5.5 | $0.00006 | $0.00107 |
| Sonnet 5.5 | $0.00003 | $0.00054 |
| Haiku 4.5 | $0.00001 | $0.00027 |
Grade A, and why
def 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 1mo 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
Find symbol definitions via th0th.
Arguments: $ARGUMENTS (first token is symbolName, optional second is a kind filter like class or function).
Strategy:
- If the user gave only a name, call
mcp__th0th__th0th_go_to_definitionfirst — it's cheaper and usually exact. - If 0 results, fall back to
mcp__th0th__th0th_search_definitionswithsearch=<name>and optionalkind=<kind>. - Render a table:
name | kind | file:lineStart-lineEnd | exported | centralityScore. - If the user asked a follow-up like "show me", offer to run
mcp__th0th__th0th_searchfor code snippets orth0th_get_referencesfor callers.
Resolve projectId from the cwd unless user specifies.
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.

def is a command published in the GitHub repository S1LV4/th0th (136 stars, last pushed 4mo ago), licensed MIT. It adds 14 tokens to every session and 268 once invoked, about $0.0001 per session on Opus 5.5. 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.
