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 | $0.00091 | $0.02247 |
| Opus 5 | $0.00046 | $0.01123 |
| Sonnet 5 | $0.00018 | $0.00449 |
| Haiku 4.5 | $0.00009 | $0.00225 |
Grade A, and why
Plan PA Days 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.

Plan PA Days
Overview
Locate research directory: Read .claude/kids-camp-planner.local.md to get the research_dir path (default: camp-research). All user data paths below are relative to this directory. The family profile is at <research_dir>/family-profile.md.
Professional Activity (PA) days are single days during the Ontario school year when students stay home while teachers participate in professional development. Plan coverage by first identifying PA day dates from the school board calendar, then finding suitable single-day programs. PA days are also called PD days (Professional Development days) in some boards.
PA Day Lookup Workflow
Step 1: Identify PA Day Dates
Use the 3-Tier School Calendar Lookup to find PA day dates:
Tier 1 - Check internal library first:
- Read the school board/name from
<research_dir>/family-profile.md - Search
${CLAUDE_PLUGIN_ROOT}/skills/camp-planning/references/school-calendars/for a matching file - If found and the school year matches, extract PA day dates directly. Inform the user: "Found [school] PA days in the internal library."
Tier 2 - Ask the user: If no internal data exists, ask: "I don't have [school] calendar data saved. Do you have the school calendar URL or PDF handy?"
- If the user provides a URL or PDF, read the document to extract PA day dates
- Save the extracted data to the internal library using the add-school-calendar skill workflow
Tier 3 - Web search: If the user doesn't have it, conduct a web search for "[school board name] school year calendar [current school year]"
- Ensure the correct school year is retrieved (e.g., 2025-2026, not previous year)
- Look for the official board website result, not third-party aggregators
- If a PDF is found, download and save it to
${CLAUDE_PLUGIN_ROOT}/skills/camp-planning/references/school-calendars/pdfs/ - Extract all PA day dates from the calendar and save the structured data to the internal library
Check calendar staleness: After loading calendar data, extract the school year from the ## YYYY-YYYY School Year header. Parse the end year (e.g., 2026 from "2025-2026"). If the current date is after September 1 of that end year, warn: "Calendar data for [board] is from [year]. The current year may have different PA days and breaks. Would you like to search for updated calendar data?" If the user says yes, run the 3-Tier School Calendar Lookup to find updated data.
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.

Plan PA Days is a skill published in the GitHub repository reggiechan74/cc-plugins (7 stars, last pushed 3mo ago), licensed MIT. It adds 91 tokens to every session and 2,247 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 2026-08-31.
