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 5.1 | $0.00012 | $0.00892 |
| Opus 5.5 | $0.00005 | $0.00357 |
| Sonnet 5.5 | $0.00002 | $0.00178 |
| Haiku 4.5 | $0.00001 | $0.00089 |
Grade A, and why
todo 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 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.
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.
This is a copy
95% identical to todo — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.
TODO Board
Use this skill when the user wants to manage a shared task list for the current workspace.
Trigger
{
"activation": {
"anyPhrases": [
"todo",
"todo list",
"blocked task",
"blocked tasks",
"add to my todo",
"show my todo"
]
},
"movement": {
"target": "desk",
"skipIfAlreadyThere": true
}
}
When this skill is activated, the agent should return to its assigned desk before handling the request.
- If the user asks from Telegram or any other external surface to add, block, unblock, remove, or read TODO items, treat that as a trigger for this skill.
- The physical behavior for this skill is: go sit at the assigned desk, then perform the TODO board workflow.
- If the agent is already at the desk, continue without adding extra movement narration.
Storage location
The authoritative task file is todo-skill/todo-list.json in the workspace root.
- Always treat that file as the source of truth.
- Never rely on chat memory alone for the latest task state.
- Create the
todo-skilldirectory andtodo-list.jsonfile if they do not exist.
Required workflow
- Read
todo-skill/todo-list.jsonbefore answering any task-management request. - If the file does not exist, create it with the schema in this document before continuing.
- After every add, remove, block, or unblock action, write the full updated JSON back to disk.
- If the file exists but is invalid JSON or does not match the schema, repair it into a valid structure, preserve any recoverable items, and mention that repair in your response.
- If the user request is ambiguous, ask a clarifying question instead of guessing.
Supported actions
- Add a task. Create a new item unless an equivalent active item already exists.
- Block a task.
Change the matching item to
status: "blocked". If the task does not exist and the request is clear, create it directly as blocked. - Unblock a task.
Change the matching item back to
status: "todo"and clearblockReason. - Remove a task. Delete only the matching item. If multiple items could match, ask for clarification.
- Read the list.
Summarize tasks grouped into
TODOandBLOCKED.
What ships with it
1 file 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.
