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 | $0.00093 | $0.01849 |
| Opus 5 | $0.00046 | $0.00924 |
| Sonnet 5 | $0.00019 | $0.00370 |
| Haiku 4.5 | $0.00009 | $0.00185 |
Grade A, and why
Budget Optimization 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 2d 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.

Budget Optimization
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.
Calculate, compare, and optimize camp costs across children, time periods, and providers. Generate budget summaries as markdown tables (default) or Excel spreadsheets. Apply Ontario-specific cost-saving strategies including tax deductions, subsidies, and discount timing.
Budget Generation Workflow
Step 1: Gather Cost Data
Read the family profile from <research_dir>/family-profile.md for budget constraints. Collect per-provider costs from <research_dir>/providers/*.md files if they exist. For each camp option, ensure the following cost components are captured:
| Component | Weekly Rate | Daily Rate |
|---|---|---|
| Base camp fee | $300/week | $60/day |
| Before-care (if needed) | $50/week | $10/day |
| After-care (if needed) | $50/week | $10/day |
| Lunch program (if not packing) | $35/week | $7/day |
| Materials/equipment fee | $25 one-time | $25 one-time |
| Registration fee | $50 one-time | $50 one-time |
| Sibling discount | -10% second child | -10% second child |
| Early-bird discount | -$25/week if registered by deadline | -$25/week equivalent |
| Multi-week discount | -5% for 4+ weeks | -5% for 20+ days |
Step 2: Calculate Using Budget Script
Run the budget calculator script to compute totals:
Weekly rate mode:
python3 ${CLAUDE_PLUGIN_ROOT}/skills/budget-optimization/scripts/budget_calculator.py \
--kids 2 \
--weeks 8 \
--base-cost 300 \
--before-care 50 \
--after-care 50 \
--lunch 35 \
--sibling-discount 10 \
--format markdown
Daily rate mode:
python3 ${CLAUDE_PLUGIN_ROOT}/skills/budget-optimization/scripts/budget_calculator.py \
--kids 2 \
--days 40 \
--daily-rate 60 \
--before-care-daily 10 \
--after-care-daily 10 \
--lunch-daily 7 \
--sibling-discount 10 \
--format markdown
What ships with it

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.

Budget Optimization is a skill published in the GitHub repository reggiechan74/cc-plugins (6 stars, last pushed 3mo ago), licensed MIT. It adds 93 tokens to every session and 1,849 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.
