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 | $0.00057 | $0.03708 |
| Opus 5 | $0.00028 | $0.01854 |
| Sonnet 5 | $0.00011 | $0.00742 |
| Haiku 4.5 | $0.00006 | $0.00371 |
Grade A, and why
claude-code-tasks 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.

The opening of the file, as written. The whole thing — 379 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Claude Code Tasks Reference
This skill is a shared reference for Claude Code's 6 Task Management tools. Load it when your skill or agent needs to create, manage, or coordinate tasks.
The tools serve two distinct purposes:
- Structured tracking — TaskCreate, TaskGet, TaskList, TaskUpdate — for organizing work items, tracking progress, managing dependencies, and coordinating agents
- Background execution — TaskOutput, TaskStop — for monitoring and controlling background processes (shells, agents, remote sessions)
Both share the task ID namespace but serve different operational needs.
This reference covers:
- Complete tool parameter tables for all six Task tools
- Status lifecycle, transition rules, and completion rules
- Naming conventions (subject vs. activeForm)
- Dependency management with DAG design principles
- Metadata conventions for categorization and tracking
For deeper content, load the reference files listed at the end of this document.
TaskCreate
Creates a new task. Returns the created task object with a system-assigned id.
Use TaskCreate for complex multi-step tasks (3+ distinct steps), plan mode tracking, or when the user provides multiple tasks or requests a todo list. Skip it for single straightforward tasks or trivial work completable in under 3 steps.
Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
subject |
string | Yes | Short imperative title for the task (e.g., "Create user schema"). Displayed in the task list UI. |
description |
string | Yes | Detailed description including context and acceptance criteria. Supports markdown. |
activeForm |
string | No | Present-continuous description shown while the task is in progress (e.g., "Creating user schema"). Displayed in the task list UI during execution. Falls back to subject if omitted. |
metadata |
object | No | Key-value pairs for categorization and tracking. Keys and values are strings. Common keys documented in the Metadata Conventions section below. |
What ships with it
2 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.

claude-code-tasks is a skill published in the GitHub repository sequenzia/agent-alchemy (43 stars, last pushed 3mo ago), licensed MIT. It adds 57 tokens to every session and 3,708 once invoked, about $0.0003 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.
