At a glance

Process flowchart standards guide. An agent skill from revfactory/harness-100.

Tasks that involve Diagrams
SKILL.md covers Standard Symbol System, Process Type Patterns, Complexity Management Rules and Process-Document Mapping, plus 1 more section
Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Flowchart Standards is an agent skill from revfactory/harness-100. Process flowchart standards guide. Notation and patterns referenced by the flowchart-designer agent when visualizing business processes in Mermaid. Used for 'flowchart standards', 'process diagram' requests. Note: BPM engine implementation is out of scope.

Its SKILL.md is about 730 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Diagrams. It works with Mermaid. The licence is Apache-2.0.

When your agent uses it

Tasks that involve Diagrams

Example prompts

“flowchart standards”
“process diagram”
“/flowchart-standards”

What it can do on your machine

Read from SKILL.md and the folder at commit 8e8d35c. 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 mermaid).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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.

Context cost

Flowchart Standards loads about 727 tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 148 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~69
When it runs · the whole SKILL.md, loaded when a task matches: ~727

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.

Flowchart Standards — Process Flowchart Standards

Standardizes the flowchart-designer agent's process visualization quality.

Standard Symbol System

Symbol	Mermaid	Meaning	Usage
Rounded rectangle	`([text])`	Start/End	Process entry/exit
Rectangle	`[text]`	Processing/Task	Unit work activity
Diamond	`{text}`	Decision/Branch	Decision point
Parallelogram	`[/text/]`	Input/Output	Document/Data
Cylinder	`[(text)]`	Data store	DB/System
Subgraph	`subgraph`	Area grouping	Department/Phase

Process Type Patterns

Pattern 1: Approval Process

mermaid

flowchart TD
    START([Request received]) --> DRAFT[Create document]
    DRAFT --> CHECK{Review}
    CHECK -->|Acceptable| APPROVE{Approval}
    CHECK -->|Unacceptable| REVISE[Revise]
    REVISE --> DRAFT
    APPROVE -->|Approved| EXECUTE[Execute]
    APPROVE -->|Rejected| REVISE
    EXECUTE --> DONE([Complete])

Pattern 2: With Error Handling

mermaid

flowchart TD
    INPUT[/Input data/] --> VALIDATE{Validation}
    VALIDATE -->|Valid| PROCESS[Process]
    VALIDATE -->|Invalid| ERROR[Error handling]
    ERROR --> LOG[(Error log)]
    ERROR --> NOTIFY[Notify owner]
    PROCESS --> OUTPUT[/Result/]
    OUTPUT --> END([End])

Pattern 3: Parallel Processing (Swim Lanes)

mermaid

flowchart LR
    subgraph Sales
        A[Receive order] --> B[Quote]
    end
    subgraph Logistics
        B --> C[Check inventory]
        C --> D[Ship]
    end
    subgraph Finance
        B --> E[Issue invoice]
        D --> F[Record revenue]
    end

Complexity Management Rules

Rule	Threshold	When Exceeded
Node count	15 or fewer	Split into sub-processes
Branch depth	3 levels or fewer	Create sub-flowcharts
Swim lanes	4 or fewer	Split the process
Crossing lines	0	Rearrange layout
Text	Verb + object, 5 words max	Abbreviate

Process-Document Mapping

Flowchart ↔ Manual mapping:
  Each rectangle (task) in the flowchart = 1 procedure in the manual
  Each diamond (decision) in the flowchart = Decision criteria in the manual
  Each subgraph (area) in the flowchart = 1 chapter in the manual

Quality Checklist

Item	Criteria
Start/End	Exactly 1 each must exist
Dead ends	None (all paths reach an endpoint)
Branch labels	Conditions specified for all paths
Exception paths	Includes error/rejection/timeout
Number mapping	Matches manual procedure numbers
