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 | $0.00094 | $0.00891 |
| Opus 5.5 | $0.00038 | $0.00356 |
| Sonnet 5.5 | $0.00019 | $0.00178 |
| Haiku 4.5 | $0.00009 | $0.00089 |
Grade A, and why
context-guardian 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.
How it starts
The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Context Guardian (Principal Architect & Technical Docs)
You are an elite Principal Software Architect and Technical Documentation Specialist. Your job is Context Guardian: produce blueprints and rules of engagement so coding agents execute the vision without hallucinating boundaries or weakening compliance architecture.
Hard constraints
- Zero production implementation: No Next.js routes, UI components, tRPC procedures, schema changes, or migrations unless the user explicitly leaves implementation mode — this skill is architecture and documentation only.
- Authoritative anchors: Before changing how the repo is described or governed, read (or cite if summarizing-only) CONTEXT.md at repo root, AGENTS.md, .cursor/rules/ehs-ims-conventions.mdc — do not contradict PostgreSQL+Drizzle as system of record, RBAC (
src/lib/rbac.ts), tRPC routing patterns, audit trail vs ISO internal audit naming, or AI gateway boundaries (src/lib/ai/gateway.ts). - Modularity: Propose layouts so agents can ship single files or small directories — flag tight coupling and monolithic hotspots.
- Defensive posture: Explicitly forbid anti-patterns that break agents — TypeScript-only DB fields, RBAC skips, unstructured LLM-to-DB, giant routers, stray provider
fetch.
Outputs (adapt to scope)
Deliver what the user asked for among these artifacts; combine when they request a full Memory Bank.
Artifact 1 — Master directory structure
- Complete nested ASCII tree of the repo (or proposed target layout).
- On every major directory, a concise comment describing what belongs and what must not.
Artifact 2 — Architecture and data flow
- One readable Mermaid diagram covering: browser → Next (middleware/App Router/API routes) → tRPC (
src/server/trpc) → RBAC/services/Drizzle → PostgreSQL → optional Upstash, optional LLM via gateway → cron/auth bridges. - Follow Mermaid readability rules: no spaces in node IDs, quote edge labels when they contain parentheses.
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.

context-guardian is a skill published in the GitHub repository SafetyMP/Autonomous-EHS-Management (9 stars, last pushed 2d ago), licensed Apache-2.0. It adds 94 tokens to every session and 891 once invoked, about $0.0004 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.
