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 5.1 | $0.00065 | $0.00387 |
| Opus 5 | $0.00032 | $0.00193 |
| Sonnet 5 | $0.00013 | $0.00077 |
| Haiku 4.5 | $0.00006 | $0.00039 |
Grade A, and why
demo-release-packager 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 9d 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
Demo Release Packager
Overview
Use this skill only after source, media, and evidence have been reviewed. It packages approved assets for handoff while excluding sensitive raw capture data by default.
Required Bundle Contents
- canonical source:
.demo.yaml, QA flow, or source artifact - approved media path: MP4, GIF/WebP preview, poster frame, or frame strip
- evidence summary with links to quality, verification, QA, storyboard, or segment files
- status: draft, needs-evidence, approved, rejected, or stale
- owner and intended destination
- commands run and checks passed
Default Exclusions
Exclude unless explicitly redacted and approved:
trace.zip- HAR or raw network dumps
- full console logs
- page error dumps with private context
- screenshots containing secrets, tokens, personal data, or customer data
- unreviewed OCR/ASR transcripts
Workflow
- Confirm the source and media are not stale.
- Confirm upstream quality or QA verdicts support the requested status.
- Apply the exclusion list before creating a handoff bundle.
- Write a release note or handoff summary with exact paths.
- Record the bundle in
docs/artifacts/artifacts.manifest.jsonwhen available.
Guardrails
- Failed or inconclusive QA evidence can produce only a draft or repro package, never an approved product demo.
- Missing analyzer evidence should downgrade status to
needs-evidence. - Do not upload, publish, or promote assets without explicit user approval.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
