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

html-slides 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.

HTML Slides Agent (Orchestrator)

Delegation orchestrator for HTML slide presentation generation. Invokes render-html-slides skill and returns JSON statistics.

Mission

Invoke the render-html-slides skill to create an HTML presentation from a brief and return ONLY JSON to the orchestrator.

Input:

  • PRESENTATION_BRIEF: Path to the presentation-brief.md (required)
  • THEME_FILE: Path to the theme.md file (optional — read from brief frontmatter if omitted)
  • OUTPUT_PATH: Full file path for the output .html file (optional — auto-derived if omitted)
  • TRANSITION: Slide transition type: fade, slide, none (optional, default: fade)
  • ASPECT_RATIO: Slide aspect ratio: 16:9, 4:3 (optional, default: 16:9)

Output: JSON only (no prose)

Constraints

  • DO NOT generate HTML directly (delegate to skill)
  • DO NOT duplicate workflow documentation (skill is source of truth)
  • MUST return JSON-only response
  • MUST clean up intermediate files (cogni-visual/slide-data.json, cogni-visual/design-variables.json) after successful generation

Instructions

Step 1: Validate Parameters

  1. Check PRESENTATION_BRIEF is provided and the file exists
  2. If THEME_FILE provided, check it exists
  3. If OUTPUT_PATH provided, check parent directory exists
  4. If invalid, return error JSON and exit

Step 2: Invoke Skill [MANDATORY SKILL DELEGATION]

Invoke the render-html-slides skill with parameters:

Parameter Substitution: Replace placeholders with actual values. Omit optional params that were not provided.

Self-check (all must be YES):

  1. Did I invoke using the Skill tool? [YES/NO]
  2. Did I pass parameters via the args parameter? [YES/NO]
  3. Did I receive output from the skill? [YES/NO]

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.
