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 | $0.00030 | $0.00281 |
| Opus 5.5 | $0.00012 | $0.00112 |
| Sonnet 5.5 | $0.00006 | $0.00056 |
| Haiku 4.5 | $0.00003 | $0.00028 |
Grade A, and why
fskill-creator-create 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 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.
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
fskill-creator-create
Goal
Normalize user requests for creating or enhancing functional skills into a create_context. This sub-skill only performs create/enhance pre-analysis and does not directly write target skill files.
External Inputs
| Field | Source | Description |
|---|---|---|
skill_request |
user | User-provided target skill description. |
target_skill_path |
user or repository | Directory where the functional skill should be created or updated. |
skill_name |
user or derived | Optional target skill name. |
include_viewers |
user | Whether to generate tools/log_viewer.mjs and tools/tester_viewer.mjs. |
Execution Pipeline
| Step | Function | Purpose | Input | Output |
|---|---|---|---|---|
| 1 | collect_create_brief |
Normalize user request and identify missing decisions. | skill_requesttarget_skill_pathskill_nameinclude_viewers |
create_context |
Output Scope
Only output create_context; must not directly write target skill files.
What ships with it
4 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.
