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 | $0.00028 | $0.00290 |
| Opus 5 | $0.00014 | $0.00145 |
| Sonnet 5 | $0.00006 | $0.00058 |
| Haiku 4.5 | $0.00003 | $0.00029 |
Grade A, and why
task-planner 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 yesterday.
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.
What it actually says
Task Planner
Use this skill when the user wants help organizing work into a schedule.
Workflow
- Gather the planning window, available hours, deadlines, and any fixed meetings or blocked days.
- Group the work into concrete tasks with estimated effort and priority.
- Produce a schedule that is realistic, not just complete.
- Flag overflow, risky deadlines, and missing information.
Output Format
Return the plan in markdown with these sections:
SummaryScheduleFollow-UpsRisks
For each scheduled item, include:
- task name
- planned date
- estimated effort
- short reason for placement
Scheduling Rules
- Put urgent and high-priority work first.
- Avoid filling a day past the stated hour limit.
- Break large work into smaller steps when that makes the plan easier to follow.
- Keep at least one buffer slot when the schedule is tight.
- Call out tasks that do not fit inside the requested window.
Script Assist
When the user provides structured JSON tasks, you can use:
python .\scripts\build_schedule.py --input <tasks.json>
The script builds a first-pass markdown schedule that you can refine in your response.
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.
