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.

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 | $0.00044 | $0.00698 |
| Opus 5.5 | $0.00018 | $0.00279 |
| Sonnet 5.5 | $0.00009 | $0.00140 |
| Haiku 4.5 | $0.00004 | $0.00070 |
Grade A, and why
templating 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 13d 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 — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.
templating — fill data into text-file templates
Render any text file (HTML, markdown, config, SQL, email, …) from a mustache template plus JSON data. Use this whenever the shape of an output is known ahead of time and only the values change — it is faster and less error-prone than writing the file by hand.
Other skills build on this one (e.g. slides composes presentation decks
from slide templates).
Quick reference
| Task | Command |
|---|---|
| Render with inline data | create-from-template --template t.html --data '{"name":"Ada"}' --output out.html |
| Render with a data file | create-from-template --template t.html --data @data.json --output out.html |
| Fail on missing keys | add --strict |
| Overwrite existing output | add -f |
Use partials ({{>name}}) |
add --partials-dir ./partials |
The command prints the absolute output path on success and exits non-zero
with a message on any error (bad JSON, missing template, existing output
without -f, missing keys under --strict).
Template syntax (mustache)
| Syntax | Meaning |
|---|---|
{{name}} |
Insert value, HTML-escaped |
{{{name}}} |
Insert value raw (no escaping) — for trusted HTML fragments |
{{#items}}…{{/items}} |
Repeat block for each array item; also renders for truthy values |
{{.}} |
The current item inside a list block |
{{^items}}…{{/items}} |
Render block only when the value is empty/falsy/missing |
{{user.name}} |
Dotted path lookup |
{{>header}} |
Include partial header (resolved from --partials-dir as header or header.html) |
{{!comment}} |
Comment, never rendered |
What ships with it
2 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.

templating is a skill published in the GitHub repository decocms/studio (409 stars, last pushed today), licensed MIT. It adds 44 tokens to every session and 698 once invoked, about $0.0002 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 2026-08-30.
