Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00018 | $0.03684 |
| Opus 5.5 | $0.00007 | $0.01474 |
| Sonnet 5.5 | $0.00004 | $0.00737 |
| Haiku 4.5 | $0.00002 | $0.00368 |
Grade A, and why
run-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 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.
How it starts
The opening of the file, as written. The whole thing — 256 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Run Tasks Skill
This skill orchestrates autonomous task execution using Claude Code's native Agent Team system. It takes tasks produced by /create-tasks, builds a dependency-aware execution plan, and executes them in waves via a 3-tier agent hierarchy: Orchestrator (this skill) plans and coordinates waves, Wave Leads manage parallel executors within each wave, and Context Managers handle knowledge flow between tasks.
The wave-lead creates its own team and coordinates teammates via SendMessage. The orchestrator communicates with the wave-lead via file-based summaries (wave-{N}-summary.md).
Load Reference Skills
Before executing any step, load the foundational references for task management and team orchestration:
Tasks Reference
Read ${CLAUDE_PLUGIN_ROOT}/../claude-tools/skills/claude-code-tasks/SKILL.md
Teams Reference
Read ${CLAUDE_PLUGIN_ROOT}/../claude-tools/skills/claude-code-teams/SKILL.md
These references provide tool parameters, lifecycle rules, messaging protocols, and orchestration patterns. The SDD-specific execution procedures are in the orchestration reference below.
Orchestration Patterns Reference (optional, for context)
Read ${CLAUDE_PLUGIN_ROOT}/../claude-tools/skills/claude-code-teams/references/orchestration-patterns.md
Orchestration Reference
Read ${CLAUDE_PLUGIN_ROOT}/skills/run-tasks/references/orchestration.md
If any reference file cannot be read, stop and report: "ERROR: Cannot load required reference. Verify the plugin installation is complete."
Argument Parsing
Parse the following arguments from the user's invocation:
| Argument | Format | Default | Description |
|---|---|---|---|
<task-id> |
positional integer | (none — all tasks) | Execute a single specific task by ID. Mutually exclusive with --task-group and --phase. |
--task-group |
<name> |
(none — all tasks) | Filter tasks to those with matching metadata.task_group |
--phase |
<N> or <N,M,...> |
(none — all phases) | Comma-separated integers. Filter tasks by metadata.spec_phase. Tasks without spec_phase are excluded when active. |
--max-parallel |
<N> |
(from settings) | Override run-tasks.max_parallel setting for this run. Must be a positive integer. |
--retries |
<N> |
(from settings) | Override run-tasks.max_retries setting for this run. Must be a non-negative integer (0 = no retries). |
--dry-run |
(flag) | false |
Complete Steps 1-3 only: load, plan, display. No agents spawned, no session directory created. |
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.

run-tasks is a skill published in the GitHub repository sequenzia/agent-alchemy (45 stars, last pushed 4mo ago), licensed MIT. It adds 18 tokens to every session and 3,684 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-03.
Other skills, from other repositories
backlog
Manage the project's tech debt backlog. Add, list, fix, wontfix, delete, prioritize, and suggest batch actions on tracked issues, run by the user to manage accumulated debt (skills file their findings through /.zuvo/backlog-add themselves, never through this skill). Modes: list [category], add [description], fix B- …
retro
Engineering retrospective from git metrics. Reports deployment frequency, release cycle span, churn hotspots, backlog health. Outputs narrative report with 3+ actionable items. Flags: --since, --path, explicit range argument.
ccc-fable
Arm, check, audit or disarm the Fable Method: the PM loop, 12 checkable gates, workflow-first posture and verifier separation, persisted in Commander state. Use when the user says fable on/off/status/audit or wants verification-gated, orchestrated work.
debt-ops-add
Register a deferred decision in the tech-debt registry. Trigger by judgment, not a marker scan, whenever a future reader would ask "why this way?": an unmade decision, stub, loosened type, bypassed check, swallowed error, a default picked "for now", or a TODO/FIXME/HACK/XXX marker. Trigger immediately whenever you…
ccc-linear
View your open Linear issues, pick one to work on (moves it to In Progress and creates a branch), create a new issue, or see a board overview, all from pickers. Use when the user types $ccc-linear, asks for their Linear issues or tickets, or wants to start work from a ticket.
ccc-onboard
Contributor first-hour plan for the current repository: reads CLAUDE.md, BIBLE.md and package.json, checks required tools, asks the contributor's role, and returns a five-step checklist plus five real starter resources. Use when someone new joins a repo or types $ccc-onboard.
