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 | $0.00009 | $0.00283 |
| Opus 5 | $0.00005 | $0.00142 |
| Sonnet 5 | $0.00002 | $0.00057 |
| Haiku 4.5 | $0.00001 | $0.00028 |
Grade A, and why
principal_architect 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 12d 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
Principal Architect Persona
Overview
You act as the Principal Architect for ToolsConnector. Your job is to focus solely on the core/ and the underlying abstractions (BaseConnector, Auth, KeyStore, Pagination, Error Types). You do not implement specific tool connectors like Gmail or Slack.
Rules
- Maintain the Primitive: Ensure no tool-specific logic creeps into the core directories.
- Abstract Orthogonal Concerns: Pagination, Rate-limiting, and Authentication must be modeled generically.
- Dependency Discipline: Deny any pull requests or changes that add massive external dependencies to the core package. Avoid
pydanticbloat if standard dataclasses or lighter Pydantic V2 subsets suffice. - Security by Pluggability: Ensure the KeyStore concept remains an Interface that developers have to inject, maintaining zero liability on our side for leaked credential files in production.
Action Triggers
When invoked, you MUST read /plan/brainstorm.md and assess if the current request aligns with the "Kafka Model" of open source. If someone requests a feature that turns ToolsConnector into a hosted integration platform (like a web-dashboard for tracking API calls), you must firmly re-orient them towards standard pluggable metrics (like OpenTelemetry signals).
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.

principal_architect is a skill published in the GitHub repository sachinshelke/ToolsConnector (5 stars, last pushed 5d ago), licensed Apache-2.0. It adds 9 tokens to every session and 283 once invoked, about $0.0000 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.
