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 | $0.00050 | $0.00551 |
| Opus 5.5 | $0.00020 | $0.00220 |
| Sonnet 5.5 | $0.00010 | $0.00110 |
| Haiku 4.5 | $0.00005 | $0.00055 |
Grade A, and why
scaffold-utils 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 25d 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.

Scaffold ArchiPy Utils
Scope
Only helpers/utils/. Do not create decorators or interceptors here.
Read first
Read these plugin rules in full before generating files (paths relative to this skill directory; Claude Code: ${CLAUDE_SKILL_DIR}/../../rules/):
../../rules/using-archipy-utils.mdc
Before writing files
- Inspect existing helpers and installed ArchiPy version for a matching utility.
- Infer project naming and function/class style.
- Ask only for an unresolved purpose or behavior. Prefer an ArchiPy utility whenever it fits.
- Preserve existing helper modules; do not overwrite.
Prefer ArchiPy
If an ArchiPy util fits, show import + usage example and stop — do not duplicate. See ../archipy-docs/reference/helpers.md
(Utils section), resolved relative to this SKILL.md's directory in the plugin installation — not the app workspace.
Custom util
Create helpers/utils/<name>_utils.py:
from __future__ import annotations
class SlugUtils:
"""Pure string helpers for URL-safe slugs — no I/O."""
@staticmethod
def slugify(value: str) -> str:
"""Return a lowercase hyphenated slug.
Args:
value: Raw display string.
Returns:
Slug suitable for path segments.
"""
cleaned = "".join(ch.lower() if ch.isalnum() else "-" for ch in value.strip())
while "--" in cleaned:
cleaned = cleaned.replace("--", "-")
return cleaned.strip("-")
- Pure functions/classes — no I/O, no DB, no adapters
- Google-style docstrings + full type hints
- Lazy-import optional deps inside functions when needed
- Brief usage snippet in the reply
Do not
- No adapter construction at module level; lazy-import optional deps inside functions when needed.
Verify
Run the repository's formatter, linter, and focused unit tests. Report the reused ArchiPy API or files created, plus commands run.

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.
- 25d ago First seen · 79 lines · 50 tokens per session scan A 124f4c45cc16
scaffold-utils is a skill published in the GitHub repository SyntaxArc/archipy-plugin (3 stars, last pushed yesterday), licensed MIT. It adds 50 tokens to every session and 551 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 2026-09-24.
