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 | $0.00095 | $0.03331 |
| Opus 5 | $0.00048 | $0.01665 |
| Sonnet 5 | $0.00019 | $0.00666 |
| Haiku 4.5 | $0.00010 | $0.00333 |
Grade A, and why
moodle-upgrade-migration 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 10d 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.

Moodle Upgrade & Migration
Overview
Moodle deprecates aggressively but rarely removes. Code from Moodle 2.x often still runs in 4.5 — but uses APIs that emit warnings, fail PHP 8 strict checks, or block plugin directory acceptance. This skill catalogs the migration path from each generation.
When to Use
- Upgrading a plugin to support a newer Moodle version
- Resolving deprecation warnings
- Migrating to PHP 8.1 / 8.2 / 8.3 / 8.4
- Plugin directory submission rejection ("uses deprecated API")
- Cross-version compat (
$plugin->requiresbump)
Strategy
- Bump
$plugin->requiresto your minimum target Moodle version - Replace deprecated APIs (table below)
- Add
upgrade.txtto document changes - Run
phpcs --standard=moodle+ visual smoke test - Bump
$plugin->version+ adddb/upgrade.phpstep if schema changed

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.

moodle-upgrade-migration is a skill published in the GitHub repository SaadRahman01/claude-moodle-dev (36 stars, last pushed 2mo ago), licensed MIT. It adds 95 tokens to every session and 3,331 once invoked, about $0.0005 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 2026-08-30.
