Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

SkillSpector: 3 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 42 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00147 | $0.01274 |
| Opus 5 | $0.00073 | $0.00637 |
| Sonnet 5 | $0.00029 | $0.00255 |
| Haiku 4.5 | $0.00015 | $0.00127 |
Grade A, and why
x-posting-license 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.
How it starts
The opening of the file, as written. The whole thing — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.
X Posting License
One fixed 1920×1080 @ 60fps, 10.35s composition. The motion is locked and doctrine-verified (overlapped keyframes end to end, zero dead frames): do NOT edit the timeline — fill the data tokens and render.
Requirements
- Node 18+ and the HyperFrames CLI via
npx(fetched from npm;@latestis mutable — pin a version, e.g.npx [email protected], if you need byte-identical re-renders over time). - macOS GPU render for the WebGL dot ground:
export PRODUCER_BROWSER_GPU_MODE=hardware. - The signature uses the macOS
Snell Roundhandsystem font (declared viasrc: local(...)); on Linux it falls back to generic cursive — still fine, less pretty.
Network and side effects (complete list)
x.com/<handle>— profile page the agent reads (data gathering).pbs.twimg.com— the avatar image download (data gathering).api.fxtwitter.com/<handle>— post count; free, no credentials (data gathering).registry.npmjs.org— the HyperFrames CLI itself, vianpx.cdn.jsdelivr.net— the composition loads GSAP (pinned3.14.2) from jsDelivr at preview/render time. Rendering is NOT fully offline.
No credentials, no paid operations, no telemetry. build.mjs writes only
inside the --out directory: it validates counters as plain non-negative
integers, strips control characters, caps lengths, HTML-escapes every profile
string before substitution, and refuses to write through symlinks.
Flow (three steps, no composition work)
<SKILL_DIR> below means this skill's own directory (wherever it is installed
— e.g. ~/.claude/skills/x-posting-license). Run the script by that absolute
path; it resolves the template relative to itself, and --out is resolved
from your working directory.
- Gather profile data — name, handle, joined month/year, followers,
following, posts, one bio line, and the 400×400 avatar. Recipes in
references/profile-data.md. - Build the project from the template:
node <SKILL_DIR>/scripts/build.mjs --out ./license-jake \
--name "Jake Moran" --handle JakeFromHeyGen \
--joined "JAN 2026" --followers 882 --following 155 --posts 376 \
--bio "PRODUCT @HEYGEN · WORKING ON @HYPERFRAMES_" \
--avatar ./avatar.jpg
What ships with it
3 files 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.
- 9d ago First seen · 104 lines · 147 tokens per session scan A 67cfed355605
x-posting-license is a skill published in the GitHub repository heygen-com/hyperframes-community-skills (66 stars, last pushed today), licensed Apache-2.0. It adds 147 tokens to every session and 1,274 once invoked, about $0.0007 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 2026-08-30.
