What it does

Workflow Yylo is an agent skill from sickn33/agentic-awesome-skills. Create and maintain validated YYLO Ledger workflow Records while keeping storage, execution, and run evidence as separate explicit boundaries.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Requires the yy CLI with the workflow record group installed. Ledger stores and validates workflow data; execution needs a separately selected runner plus…

The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.

Example prompts

  • “/workflow-yylo”

Requirements

  • Compatibility (from SKILL.md): Requires the `yy` CLI with the `workflow` record group installed. Ledger stores and validates workflow data; execution needs a separately selected runner plus explicit authority.

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Ledger stores and validates workflow data. It does not execute workflows.
  2. A separately selected YYLO runner executes reviewed workflow data. Storage
  3. Artifact Records retain run evidence. Do not overwrite the workflow

What it can do on your machine

Read from SKILL.md and the folder at commit b84d35a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash and yaml).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Requires the `yy` CLI with the `workflow` record group installed. Ledger stores and validates workflow data; execution needs a separately selected runner plus explicit authority.

    From compatibility in the SKILL.md frontmatter.

Context cost

Workflow Yylo loads about 1.1k tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 393 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~39
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Use YYLO workflow Records

Treat Ledger as the source of truth for workflow identity, validated definition, and revision history. Use yy ledger in a YYLO controller or yylo-ledger standalone. Inspect COMMAND workflow --help; if the namespace is absent, do not invent it or edit Ledger storage directly.

Keep three boundaries distinct

  1. Ledger stores and validates workflow data. It does not execute workflows.
  2. A separately selected YYLO runner executes reviewed workflow data. Storage does not grant execution, network, mutation, release, or deployment authority.
  3. Artifact Records retain run evidence. Do not overwrite the workflow definition with stdout, logs, model output, reports, or receipts.

The read-only Ledger host also has no workflow execution endpoint.

Discover and inspect

bash
yy ledger workflow search --text "release verification" --projection summary --limit 20 -f json
yy ledger workflow get RECORD_ID -f json
yy ledger workflow get RECORD_ID --raw
yy ledger workflow get RECORD_ID --validated

Prefer immutable IDs after discovery. Use bounded projections and explicit archive scope. --validated emits normalized YAML only after schema validation.

Author safe workflow data

A workflow v1 document requires a mapping with schema_version: v1, a non-empty workflow_id, and a steps list whose step IDs are non-empty and unique.

yaml
schema_version: v1
workflow_id: focused-validation
steps:
  - id: test
    command: ["npm", "test"]

Create through file/stdin transport:

bash
yy ledger workflow create --title "Focused validation" --file workflow.yaml

Ledger rejects unsafe or non-portable YAML, including duplicate keys, aliases, anchors, explicit tags, recursive structures, non-string mapping keys, implicit date/time values, non-finite numbers, CRLF input, and unsupported values. Never weaken validation by storing executable shell as an unvalidated substitute.

Revise safely

Read the current revision and history, then follow the installed workflow update --help compare-and-replace contract. Bind updates to the expected revision and preimage/digests, validate the result, and read it back. On drift, stop and reconcile instead of forcing. Archive is non-destructive.

Before execution, freeze the exact workflow Record ID, revision, payload digest, runner identity, inputs, and granted authorities. After execution, store bounded outputs under artifact-yylo with workflow/run provenance. An execution request never implies merge, release, publication, deployment, or production authority.

Complete request

$ARGUMENTS

When to Use

  • You need to find, create, or revision-safe update validated YYLO Ledger workflow Records.
  • You must keep storage, execution, and run-evidence boundaries explicit.

Limitations

  • Ledger stores and validates workflow data; it never executes workflows and grants no execution, network, mutation, release, or deployment authority.
  • Run evidence belongs in artifact-yylo records with workflow/run provenance - never overwrite the workflow definition with outputs.
  • An execution request never implies merge, release, publication, deployment, or production authority. On revision drift, stop and reconcile instead of forcing.
Example
bash
yy ledger workflow search --text "release verification" --projection summary --limit 20 -f json
yy ledger workflow get RECORD_ID --validated
