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 | $0.00024 | $0.00594 |
| Opus 5 | $0.00012 | $0.00297 |
| Sonnet 5 | $0.00005 | $0.00119 |
| Haiku 4.5 | $0.00002 | $0.00059 |
Grade A, and why
thoth:extension 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.

Real Runtime Execution
The repo-local Thoth runtime command for this slash command has already been executed before Claude sees this prompt.

Response Contract
- Treat the structured bridge payload above as the only authority for this invocation.
- If
bridge_successisfalse, report the exact bridge failure and stop. - If stdout starts with
version=, repeat stdout exactly and output nothing else. - If
bridge_successistrue, report only the real command result in one short receipt. - If extra evidence is required, inspect only the smallest artifact explicitly named by the bridge payload.
- Do not launch broad Explore, Task, cache/source scans, or background investigation after the bridge result.
- If the result exposes blockers or asks for human decisions, use AskUserQuestion to ask only the unresolved questions and stop.
- Do not expand into runtime explanation, walkthroughs, or extra command execution.

Objective
Create, list, validate, and manage project-local Dashboard/TUI extensions and experiment registry objects while preserving manifest schema v3 and local audit receipts.
Hard Stops
- Do not execute extension Python code while creating, listing, validating, or managing experiments.
- Do not write extension sources outside .thoth/extensions/plugins unless an explicit project-relative source was provided.
- Do not treat local action receipts as portable project authority.
- Do not persist absolute downstream paths into portable experiment registry objects.
- Do not invent extension capabilities beyond the CLI arguments and manifest contents.
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.
- 2d ago First seen · 64 lines · 24 tokens per session scan A 517e6735de72
thoth:extension is a command published in the GitHub repository SeeleAI/Thoth (51 stars, last pushed 23d ago), licensed MIT. It adds 24 tokens to every session and 594 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 2026-08-30.
