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 | $0.00134 | $0.03456 |
| Opus 5 | $0.00067 | $0.01728 |
| Sonnet 5 | $0.00027 | $0.00691 |
| Haiku 4.5 | $0.00013 | $0.00346 |
Grade A, and why
lw-lms-backend-extend 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 8d 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.

LW LMS: backend extension contract
For companion plugins or themes extending LW LMS from PHP: enrollment automation, certificates, progress writes, access checks, custom settings tabs, analytics, admin tooling, and integrations with WooCommerce, WooCommerce Subscriptions, or WooCommerce Memberships.
BETA NOTICE. The plugin README says the plugin is under active development and not recommended for production use. Pin a tested version and review
CHANGELOG.mdbefore upgrading. This skill is verified against local lw-lms v1.6.0.
Version deltas that matter
- v1.6.0:
lw_lms_has_course_accessis reachable again as the final logged-in paid-course decision after all built-in checks.AccessRepository::revoke_by_source()adds source-scoped stored-access revocation. Minimum PHP is now 8.2. - v1.5.1: maintenance release, no functional changes.
- v1.5.0: WooCommerce Memberships access. Paid courses can link membership plans through
_lw_lms_membership_plan_ids. Active members get access at read time throughMembershipChecker; no DB schema change and no access row is written. - v1.4.0: WP-CLI operational workflow added. Use
lw-lms-wp-cli-operationsfor those commands. - v1.4.0:
lw_lms_settings_tabsfilter andSettingsPage::get_settings_group()added for companion settings tabs and sharedoptions.phpsaving. - v1.4.0: course REST
contentis public; only lesson content remains access-gated. - v1.3.0: enrollment/progress hook contract added or centralized:
lw_lms_pre_grant,lw_lms_after_grant,lw_lms_after_revoke,ProgressRepository::mark_course_completed(), read/write splits.
v1.6.0 course-access filter contract
AccessChecker::has_course_access() now reaches lw_lms_has_course_access after the complete built-in paid-course cascade: access rows, parent subscriptions, variation subscriptions, WooCommerce Memberships, then legacy purchases. The callback receives the aggregate built-in result and has final say, so it can grant or deliberately deny logged-in paid-course access.
What ships with it
1 file 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.
