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 | $0.00018 | $0.00246 |
| Opus 5.5 | $0.00007 | $0.00098 |
| Sonnet 5.5 | $0.00004 | $0.00049 |
| Haiku 4.5 | $0.00002 | $0.00025 |
Grade A, and why
explore-codebase 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
Explore codebase
Use before medium or large changes. Full policy: docs/AI_WORKFLOW.md (code exploration).
Steps
- Read
README.md,docs/AI_WORKFLOW.md, andCLAUDE.mdfor stack and boundaries. - Identify entry points:
server/index.js,client/src/main.jsx,client/src/App.jsx. - List modules that will be touched; note
server/vsclient/split. - Search within
server/orclient/first (scopedrgor editor search); avoid whole-repo grep until needed. - If using MCP (e.g. cursor-ide-browser), read tool schemas, then use structured navigation — not blind full-tree scans.
Checklist
- Entry points and data flow for the feature are understood.
- No plan to violate architecture boundaries in
docs/AI_WORKFLOW.md.
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.

explore-codebase is a skill published in the GitHub repository iamadi11/mcp-ui-poc (8 stars, last pushed 29d ago), licensed MIT. It adds 18 tokens to every session and 246 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 2026-08-31.
