Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

ciel-documentation-engine 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 2d 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

CIEL ADAPTATION: Documentation Engine

This framework governs the lifecycle of technical documentation within the CIEL ecosystem. It ensures that all documentation is accurate, spec-compliant, and semantically queryable.

Core Capabilities

  1. Spec-Doc Synchronization: Automatically validates that documentation (e.g., README.md) stays in sync with actual project structure and metrics.
  2. Semantic Indexing: Prepares documentation for high-density RAG (Retrieval-Augmented Generation) by enforcing structured headings and metadata.
  3. Format Enforcement: Validates and auto-fixes Markdown standards (MD040, MD060) via integrated linting hooks.
  4. Template Application: Provides standardized templates for new skills, subagents, and council reports.

Mandates

  • Single Source of Truth: Metrics (like skill counts) MUST be derived from implementation, not hand-coded.
  • Link Integrity: Every internal link in the documentation must be verified for resolution.
  • Tone & Style: Documentation must maintain a professional, senior-engineering tone.

Automation Hooks

  • Post-Build: Generates updated MANIFEST.md and INDEXING.md.
  • Pre-Commit: Runs markdownlint and verifies version consistency.

Anti-Patterns

  • Stale Metrics: Quoting version numbers or counts that do not match the current repo state.
  • Broken References: Linking to deleted files or private directories in public documentation.
Changes

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.
