Verasic Fusion — Multi-Model Orchestration

Source of truth

Never duplicate the protocol in chat — follow it.

Workflow

1. Help path — if the user invokes fusion with no question or asks for help, relay

references/helper.md (adjust path prefix for install root).

1. Pre-flight — require question, mode, and models (≥ 2). No defaults. Validate

slugs via references/models.md. Apply soft cap 4 (warn) and hard cap 6 (block unless acknowledge: proceed with N models). Validate template extras (e.g. lens-map for stakeholder-lens).

1. Read template — when template: is set, read templates/<slug>.md before dispatch.

Resolve absolute skill-root paths for subagent tasks (see protocol).

1. Package prompt — user question + attachments + your framing/analysis. Subagents must

not see each other's answers.

1. Dispatch — in Cursor: spawn Task subagents in parallel, one per model, with

the model slug from the roster. Each subagent gets absolute protocol + template paths; subagent must read the template file. Do not paste the full template inline. Optional fallback: extracted ## Subagent instruction + ## Subagent answer shape only.

1. Curate & deliver — per mode (verbatim, fusion, verbatim+fusion). Never

rewrite subagent prose in verbatim. Surface conflicts. Attribute in ## by model.

1. Refuse — if all subagent outputs are unusable, say so; do not invent fusion.
2. Degraded — if Task/subagents unavailable, ask upfront before sequential

single-context simulation.

Orchestration (Cursor)

Read .cursor/skills/verasic-fusion/references/fusion-protocol.md first and follow it exactly.

Help

If the user sent no question, only help, or an empty invocation — relay .cursor/skills/verasic-fusion/references/helper.md verbatim (adjust the path prefix if this skill is installed elsewhere).

Required from the user's message

Parse or ask for:

• mode: one of verbatim, fusion, verbatim+fusion
• models: comma-separated slugs (minimum 2) — validate against

.cursor/skills/verasic-fusion/references/models.md

• The question body

Optional: template:, acknowledge:, template extras (options:, lens-map:, etc.)

No default models. No default mode. If either is missing, ask before spawning.

Steps

1. Pre-flight per protocol (roster caps: warn at 4, hard cap 6 unless acknowledged).
2. Resolve skill root and read the active template file when template: is set.
3. Package prompt: user question + attachments + your framing — no other subagent answers.
4. Spawn Task subagents in parallel, one per model, foreground, with each model slug.
5. Subagent tasks: absolute paths to protocol + template; subagent must read the

template file. Do not paste the full template inline. Optional: append extracted ## Subagent instruction + ## Subagent answer shape as fallback only (see protocol).

1. Subagents: readonly tools only; no mutations.
2. Curate and deliver per mode. Never rewrite subagent prose in verbatim.
3. Surface conflicts; attribute in ## by model.
4. If all subagent outputs unusable — refuse fusion; say why.
5. If Task/subagents unavailable — ask before degraded sequential fusion.

Subagent task prompt (one per model)

Replace <skill-root> with the absolute skill directory (contains references/fusion-protocol.md).

Readonly fusion subagent. Follow <skill-root>/references/fusion-protocol.md readonly rules.

Template: <skill-root>/templates/<slug>.md
You MUST read this file before answering. Use ## Subagent instruction and
## Subagent answer shape only. Ignore Fusion mapping / Fusion notes.

<optional fallback: Subagent instruction + answer shape — only if needed>

## Packaged prompt
<packaged prompt from main agent>

Answer in the template shape. Do not mutate the repo.

Deliver

Format output per protocol and active template. Include every core skeleton section in fusion modes (## answer, ## reasoning, ## conflicts, ## by model, ## recommendation).

Without subagents

Read references/fusion-protocol.md and execute the full workflow yourself, including degraded confirmation when parallel spawn is impossible.

Hard rules

• Decision support only — no mutations.
• No default models or mode.
• No silent model substitution.
• Conflicts never silently flattened.
• composer-2.5-fast should appear in suggested rosters (user's primary model).

Templates

Read templates/<slug>.md before dispatch when template: is set. All nine ship with this skill — see references/fusion-protocol.md registry.
