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 | $0.01186 | $0.01186 |
| Opus 5 | $0.00593 | $0.00593 |
| Sonnet 5 | $0.00237 | $0.00237 |
| Haiku 4.5 | $0.00119 | $0.00119 |
Grade A, and why
thousandeyes-ai-agents-toolkit AGENTS.md 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 8d 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.

AGENTS
Agent guidance for working in this repository.
Scope and intent
- This repo contains the ThousandEyes AI Agents Toolkit.
- The toolkit can include multiple integrations (for example Cursor plugin assets, Claude Code plugin assets, MCP configuration, and future agent/tooling integrations).
- Make minimal, targeted edits that match the user request.
- Do not refactor unrelated files or reorganize directories unless requested.
Repository structure guidance
- Keep integration boundaries clear (plugin files, docs, scripts, assets) and avoid cross-cutting changes unless requested.
- Prefer adding new integration-specific content in clearly named folders/files.
- Keep documentation aligned with the actual repository layout and supported integrations.
Shared skill mirroring guidance
- Repository-root
skills/is the source of truth for shared skill content. - Cursor and Claude Code can use root-level skills directly, but the Codex plugin must carry mirrored copies under
plugins/thousandeyes/skills/. - When adding, removing, or editing any shared skill under
skills/, sync the Codex plugin copies withbash scripts/sync_codex_skill.sh sync. - Before finishing skill-related work, verify mirrors with
bash scripts/sync_codex_skill.sh check. - Keep
.githooks/pre-commitaligned with that script so commits fail when root and Codex skill copies drift. - Keep shared skills compatible with both Cursor and Claude Code expectations:
skills/<skill-name>/SKILL.mdwith valid frontmatter.
Cursor plugin-specific guidance
- The Cursor plugin manifest is
.cursor-plugin/plugin.jsonat repository root. - The only required manifest field is
name(lowercase, kebab-case, alphanumerics/hyphens/periods; must start and end with alphanumeric). - Keep optional metadata accurate when editing:
description,version,author(namerequired,emailoptional),keywords,logo, etc. See Building plugins.

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.
