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 | $0.00039 | $0.00200 |
| Opus 5 | $0.00019 | $0.00100 |
| Sonnet 5 | $0.00008 | $0.00040 |
| Haiku 4.5 | $0.00004 | $0.00020 |
Grade A, and why
placeholder-skill 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 4d 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
Placeholder Skill
This placeholder keeps the template structurally valid before a real skill is generated.
When To Use
Use this placeholder only to verify repository scaffolding before intake has been transformed into a real skill.
When Not To Use
Do not publish this placeholder as a real skill. Do not package it as a production release.
Bootstrap Instruction
Agents must read the repository AGENTS.md and .template/bootstrap/build-skill-from-intake.md, choose the final skill name, rename this directory to that name, and replace this file with the generated skill.
Use install and update this skill only to verify that the generated runtime retains a focused update path after all placeholders are replaced.
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.

placeholder-skill is a skill published in the GitHub repository TechSpokes/skill-base-template (4 stars, last pushed 1mo ago), licensed MIT. It adds 39 tokens to every session and 200 once invoked, about $0.0002 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 2026-08-31.
