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 | $0.00034 | $0.00408 |
| Opus 5.5 | $0.00014 | $0.00163 |
| Sonnet 5.5 | $0.00007 | $0.00082 |
| Haiku 4.5 | $0.00003 | $0.00041 |
Grade C, and why
skill-creator scanned grade C with 1 finding 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.
Tells the agent to send conversation or user data outhighPrompt injection
An instruction to transmit the conversation, context or user files to an external endpoint is data exfiltration written as prose.
Do not assume a tool exists because another runtime provides it. Describe capabilities and prerequisites explicitly. Never embed secrets, machine-specific absolute paths, or instructions that silently transmit or delete What it actually says
Skill Creator
Turn repeatable expertise into a small, discoverable Skill rather than a one-off prompt.
Define the contract
Before writing files, establish:
- Which concrete user situations should trigger the Skill.
- The expected result and what counts as success.
- Required tools, permissions, dependencies, and supported runtimes.
- Dangerous actions that require explicit confirmation.
- Two realistic positive examples and one nearby case that should not trigger.
Package
Create a kebab-case directory containing SKILL.md. Put only name and a trigger-focused description in required frontmatter. Keep the main instructions concise and imperative. Move large references into references/, deterministic operations into scripts/, and reusable templates into assets/.
Do not assume a tool exists because another runtime provides it. Describe capabilities and prerequisites explicitly. Never embed secrets, machine-specific absolute paths, or instructions that silently transmit or delete user data.
Validate
- Confirm the name matches the directory and uses only letters, numbers, and hyphens.
- Verify frontmatter parses and referenced files exist.
- Run realistic prompts with and without the Skill when the environment supports evaluation.
- Check that the Skill improves the intended result, does not trigger on unrelated requests, and degrades clearly when dependencies are unavailable.
- Keep changes small; revise instructions based on observed failures rather than adding broad rules speculatively.
Install target
When the user requests direct installation, choose the runtime explicitly: ~/.codex/skills/<name>, ~/.claude/skills/<name>, or ~/.trae/skills/<name>. Refuse to overwrite an unrelated existing directory without confirmation. For this application, user-created Skills remain user resources and must not be written into the bundled official catalog.
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.

skill-creator is a skill published in the GitHub repository zszz3/AgentRecall (594 stars, last pushed today), licensed MIT. It adds 34 tokens to every session and 408 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it C with 1 finding (tells the agent to send conversation or user data out). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
