A router for the Zuvo skill collection, which chooses the relevant skill for a user's request.

Use it as the entry point for requests that may be handled by Zuvo's writing, testing, design, worktree, or other skills.

It avoids having to select the right add-on manually when several skills could handle different kinds of work.

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.

Any agent

Token cost

What it costs to keep this loaded

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	$0.00033	$0.04836
Opus 5.5	$0.00013	$0.01934
Sonnet 5.5	$0.00007	$0.00967
Haiku 4.5	$0.00003	$0.00484

Security

Grade A, and why

using-zuvo 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 today.

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.

Zuvo Skill Router

You have access to the Zuvo skill ecosystem. Before acting on any user request, check the routing table below. If a skill matches, invoke it using the Skill tool. Do not implement the task yourself when a skill exists for it.

If the user asks "zuvo version", "what version", or "which zuvo" — print the version banner above and stop. Do not invoke any skill.

How Routing Works

Read the user's message
Match intent against the routing table
If a skill matches, invoke it: Skill(skill="zuvo:<name>")
If no skill matches, proceed normally

Re-evaluate intent on each message. A continuation resumes the active skill at its recorded phase; it does not reload the router or restart completed stages. Apply ../../shared/includes/execution-policy.md and the read-once protocol in ../../shared/includes/evidence-reuse.md.

Response Surface Policy

If the session context includes the compressed response protocol, apply it by surface:

Working chatter such as progress updates, clarifying questions, design summaries, and audit summaries defaults to TERSE.
Findings and operational checklists default to STRUCTURED_TERSE.
Complete formal output blocks belong in artifacts under zuvo/, docs/ or memory/. Human finals state the outcome, checks, limitations and artifact links; explicit requests for depth stay STANDARD.
Keep code, commands, paths, URLs, symbols, dates, versions, quoted errors, and structured literals exact.
When evidence is partial, preserve calibration with conf: confirmed, conf: likely, or conf: unclear.
V1 scope is hook-enabled main assistant behavior. Direct skill invocation or sub-agent output may remain on legacy verbosity in degraded mode.

Routing Table

Priority 1 — Pipeline (multi-file features)

User intent	Skill	Notes
Build a feature, add major functionality, implement a design	`zuvo:brainstorm`	Start here for anything touching 5+ files or requiring design decisions
Plan implementation tasks	`zuvo:plan`	Uses spec from `docs/specs/*-spec.md` if available, otherwise plans from user description
Continue from approved plan	`zuvo:execute`	Requires plan artifact in `docs/specs/*-plan.md`

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.
