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 | $0.01197 | $0.01197 |
| Opus 5 | $0.00598 | $0.00598 |
| Sonnet 5 | $0.00239 | $0.00239 |
| Haiku 4.5 | $0.00120 | $0.00120 |
Grade A, and why
cursorrules 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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.
VibeTrace — Automatic Conversation Recording xxxxxx、
You are an agent in a VibeTrace-enabled project. At the end of every response where you made code changes or provided a substantive answer, you MUST generate a metadata record of this conversation turn.
This metadata powers the VibeTrace VS Code extension, which gives the user a visual timeline of their entire project's vibe-coding journey.
1. Determine Session ID
The session_id identifies which agent window this conversation belongs to. It should be human-readable so the user can recognize it in the VibeTrace sidebar.
- First turn in this window: Create a session_id from the user's first request — a short CamelCase topic + 3 random lowercase letters. Example: user asks "add login page" →
LoginPage-k7m. - Subsequent turns: Reuse the session_id from earlier in this conversation. Do not change it.
2. Determine Module
The module field classifies which business feature this turn belongs to.
- BEFORE assigning a module, you MUST read the file
.vibe/MODULE_DICT.mdusing the Read File tool. - If the current work matches an existing module in the dictionary, use that EXACT name (case-sensitive).
- If NO existing module matches, you may create a new one.
- New module names should be short CamelCase (e.g.,
UserProfile,PaymentGateway,DashboardUI). - Do NOT create variants of existing modules (e.g., if
Authexists, do NOT createAuthenticationorauth).
- New module names should be short CamelCase (e.g.,
3. Generate the Metadata JSON
After completing the user's request, create a JSON file with the following structure:
{
"id": "<YYYYMMDD>-<session_id>-<3randomchars>",
"session_id": "<ShortTopic>-<3chars>, e.g. WechatQrLogin-a3f",
"module": "<your determined module name>",
"original_prompt": "<the user's raw prompt, copied verbatim>",
"intent": "<1-sentence condensation of what the USER asked for>",
"summary": "<1-sentence summary of what YOU did to fulfill it>",
"impactFiles": [
{
"path": "relative/path/to/file.ts",
"action": "create | modify | delete | read",
"description": "<one-line description of what changed and why>"
}
],
"unresolved_issues": "<optional — things left undone, config needed, follow-up required>"
}
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.

cursorrules is a cursor rule published in the GitHub repository zpeakj/vibe-trace (5 stars, last pushed 3mo ago), licensed MIT. It adds 1,197 tokens to every session, about $0.0060 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 2026-08-31.
