## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Supply Chain Security**: 83/100
  - No malware found by supply-chain analysis.
  - CVE check failed: a known medium-severity CVE affects @hono/node-server 1.19.17, reached via @modelcontextprotocol/sdk > @hono/node-server. A fixed version is available.
  - No install/post-install scripts declared.
  - Only part of the dependency tree could be resolved (104 of 108), so this covers what we could see, not the whole tree.
- **Provenance & Transparency**: 45/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (Apache-2.0).
  - Actively maintained (last published 28 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 0/100
  - Schema quality not yet verified: our sandbox run of this package did not complete, so we have no schema to assess.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: our sandbox run of this package did not complete, so we have no schema to compare.
- **Tool Coverage**: 0/100
  - Tool coverage not yet verified: our sandbox run of this package did not complete, so we have no tool definitions to assess.
- **Capabilities**: 0/100
  - Protocol version not yet verified: our sandbox run of this package did not complete, so we never saw its MCP handshake.

**Unverified: 4 categories.** Categories scored 0 because our sandbox run of this package has not given us the schema these checks need to read. That is a gap on our side rather than a finding about the package, and we only credit what we can confirm, so the score stands at 0 until the capture succeeds. We are working through the fleet, so this normally clears without any action from you.

## MCP tools (7)

### `list_workflows` (~49 tokens)

List workflows

Discover .slang workflow files in the project (.claude/workflows/) and global (~/.claude/workflows/) directories. Returns each flow's name, title, params, and agent count.

### `get_slang_grammar` (~67 tokens)

Get slang grammar

Return a concise slang grammar cheatsheet (constructs + a complete example) so you can GENERATE a workflow on the fly and run it inline via run_workflow(source). Validate generated source with validate_workflow(source) first; run_workflow also rejects parse/static-analysis errors.

### `validate_workflow` (~112 tokens)

Validate workflow

Parse and statically analyze one workflow (deadlock detection, unknown refs, missing converge/budget, orphan outputs) without running it. Identify it by `name` or absolute `path`.

Input parameters:

- `name` (string): Flow name or .slang filename (project scope preferred).
- `path` (string): Absolute path to a .slang file (overrides `name`).
- `source` (string): Inline .slang source to validate (overrides name/path) — validate generated flows before running.

### `run_workflow` (~264 tokens)

Run workflow

Parse and run a .slang workflow to completion, dispatching each agent through the Claude Agent SDK and validating results against output contracts. Identify it by `name` or `path`; pass flow `params` as an object. Returns the final flow status and each agent's output. Rejects parse/static-analysis errors before running. Default runs synchronously (returns the final status + each agent's output). Pass background:true to start the run and return a workflow_id immediately, then poll get_trace/get_topology/get_workflow_state to watch it live; @Human escalation only works in synchronous runs.

Input parameters:

- `background` (boolean): Start the run and return a workflow_id immediately, then poll get_trace/get_topology/get_workflow_state. (@Human escalation unsupported in background.)
- `model` (string): Default model for agents without api_configuration (e.g. sonnet).
- `name` (string): Flow name or .slang filename.
- `params` (object): Flow parameters as a key/value object.
- `path` (string): Absolute path to a .slang file (overrides `name`).
- `source` (string): Inline .slang source (overrides name/path) — e.g. a workflow an LLM generated on the fly.

### `get_workflow_state` (~64 tokens)

Get workflow state

Return the serialized FlowState for a run started by `run_workflow`: per-agent status, opIndex, bindings, round, budget usage, and flow status. Identify it by `workflow_id`.

Input parameters:

- `workflow_id` (string, required): Id returned by run_workflow.

### `get_topology` (~61 tokens)

Get workflow topology (Mermaid)

Return the current agent topology of a run as a Mermaid flowchart (nodes colored by status, plus live sending/waiting edges). Render it inline. Identify it by `workflow_id`.

Input parameters:

- `workflow_id` (string, required): Id returned by run_workflow.

### `get_trace` (~87 tokens)

Get workflow trace (Mermaid sequence + event log)

Return a run's execution trace as a Mermaid `sequenceDiagram` (round-by-round: who staked/routed to whom, commits, escalations, terminal event) plus the raw event log. The timeline counterpart to `get_topology`'s snapshot. Render the diagram inline. Identify it by `workflow_id`.

Input parameters:

- `workflow_id` (string, required): Id returned by run_workflow.
