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 | $0.00022 | $0.00473 |
| Opus 5 | $0.00011 | $0.00236 |
| Sonnet 5 | $0.00004 | $0.00095 |
| Haiku 4.5 | $0.00002 | $0.00047 |
Grade A, and why
task-list 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 3d 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.
What it actually says
Task List Skill
Track multi-step tasks to ensure nothing is forgotten.
When to use
- The request requires 4 or more distinct steps
- You need to perform several operations in sequence
Instructions
- Add tasks before starting multi-step work.
- Mark exactly one task in progress while working.
- Update task status as each step completes.
- Keep task text concise and action-oriented.
How to use
Use the tasks tool directly. Do NOT use run_code, execute, or write_file for task management.
1. Add tasks at the start
tasks(operation="add_multiple", content="Step one; Step two; Step three")
This clears any previous tasks. Each request starts fresh.
Examples
tasks(operation="add_multiple", content="Inspect repo; Run tests; Summarize findings")
tasks(operation="start", task_id="task_1")
tasks(operation="complete", task_id="task_1")
2. Start a task before working on it
tasks(operation="start", task_id="task_1")
3. Complete a task when done
tasks(operation="complete", task_id="task_1")
4. Check what's next
tasks(operation="next")
All operations
| Operation | Args | Description |
|---|---|---|
add_multiple |
content="t1; t2; t3" |
Add tasks (clears previous) |
start |
task_id="task_1" |
Mark in_progress |
complete |
task_id="task_1" |
Mark completed |
cancel |
task_id="task_1" |
Cancel a task |
list |
(none) | Show all tasks |
next |
(none) | Get next pending task |
Rules
- One task in_progress at a time
- Start before working, complete when done
- Do not leave tasks hanging
What ships with it
3 files 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.

task-list is a skill published in the GitHub repository NVIDIA/SkillEvaluator (357 stars, last pushed 3d ago), licensed Apache-2.0. It adds 22 tokens to every session and 473 once invoked, about $0.0001 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 2026-08-30.
