Token cost

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.

Security

Grade A, and why

migrate-bootstrap scanned grade A with 1 finding 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.

Migrate a Traditional Power Pages Site from Bootstrap 3 to Bootstrap 5

Guide the user through migrating a traditional / native Power Pages site from Bootstrap 3 to Bootstrap 5. Follow a systematic approach: verify tooling, acquire and back up the site, assess scope, run the pac pages bootstrap-migrate engine, review the change report, apply the residual fixes the engine can only flag, upload (which auto-enables the runtime flag), verify, and validate.

Core Principles

  • Traditional sites only: This skill targets traditional Power Pages sites (Liquid web templates, *.webtemplate.source.html, *.html/.aspx/.ascx, *.css, sitesetting.yml). It does NOT apply to code sites (React/Vue/Angular/Astro) — they are never Bootstrap-3-based. If the target is a code site, stop and tell the user this skill doesn't apply.
  • The engine does the bulk; you do the residual: pac pages bootstrap-migrate deterministically applies the well-known class renames. The skill's value is assisting with the hierarchy / CSS changes the engine only logs (see references/bootstrap-v5-manual-fixes.md).
  • Non-destructive, with a restore point: The engine writes a new <folder>V5 copy and never edits the source in place. Still, snapshot the source folder (git) before doing anything.
  • Assist and flag — never silently rewrite: Residual fixes are Liquid-aware and can break layouts. Apply them with per-category consent; when a case is ambiguous (e.g. Liquid conditionals), flag it for the user instead of guessing.
  • Verify the runtime flag flip via pac-log.txt: pac pages upload flips the server-side Bootstrap 5 flag automatically, but flip outcomes are logged and swallowed by the CLI. Never trust the upload exit code alone. The authoritative record is the PAC diagnostic log (pac telemetry status → pac-log.txt); grep it for BootstrapV5UploadPostProcessor. The flip requires an active portal — a website record with no provisioned site logs no portal found and skips.
  • Use TaskCreate/TaskUpdate: Create the todo list upfront with all 8 phases before starting work.

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.
