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 | $0.00070 | $0.03139 |
| Opus 5 | $0.00035 | $0.01570 |
| Sonnet 5 | $0.00014 | $0.00628 |
| Haiku 4.5 | $0.00007 | $0.00314 |
Grade A, and why
skill-064 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 6d 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 — 430 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Controllers vs Server Scripts: Error Handling
┌─────────────────────────────────────────────────────────────────────┐
│ CONTROLLERS HAVE FULL PYTHON POWER │
├─────────────────────────────────────────────────────────────────────┤
│ │
│ ✅ try/except blocks - Full exception handling │
│ ✅ raise statements - Custom exceptions │
│ ✅ Multiple except clauses - Handle specific errors │
│ ✅ finally blocks - Cleanup operations │
│ ✅ frappe.throw() - Stop with user message │
│ ✅ frappe.log_error() - Silent error logging │
│ │
│ ⚠️ Transaction behavior varies by hook: │
│ • validate: throw rolls back entire save │
│ • on_update: document already saved! │
│ • on_submit: partial rollback possible │

Main Decision: Error Handling by Hook
┌─────────────────────────────────────────────────────────────────────────┐
│ WHICH LIFECYCLE HOOK ARE YOU IN? │
├─────────────────────────────────────────────────────────────────────────┤
│ │
│ ► validate / before_save │
│ └─► frappe.throw() → Rolls back, document NOT saved │
│ └─► try/except → Catch and re-throw or handle gracefully │
│ │
│ ► on_update / after_insert │
│ └─► Document already saved! frappe.throw() shows error but saved │
│ └─► Use try/except + log_error for non-critical operations │
│ └─► Critical failures: frappe.throw() (shows error, doc is saved) │
│ │
│ ► before_submit │
│ └─► frappe.throw() → Prevents submit, stays draft │
│ └─► Last chance for validation before docstatus=1 │
│ │
│ ► on_submit │
│ └─► Document is submitted! throw shows error but docstatus=1 │
│ └─► Critical: throw causes partial state (submitted but failed) │
│ └─► Better: validate everything in before_submit │
│ │
│ ► on_cancel │
│ └─► Reverse operations - use try/except for each reversal │
│ └─► Log errors but try to continue cleanup │

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.
- 6d ago First seen · 430 lines · 70 tokens per session scan A e42c44016941
skill-064 is a skill published in the GitHub repository legendtkl/agentic-skill-router (5 stars, last pushed 3mo ago), licensed MIT. It adds 70 tokens to every session and 3,139 once invoked, about $0.0003 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 2026-09-03.
