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.

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 | $0.00049 | $0.01483 |
| Opus 5.5 | $0.00020 | $0.00593 |
| Sonnet 5.5 | $0.00010 | $0.00297 |
| Haiku 4.5 | $0.00005 | $0.00148 |
Grade A, and why
flowchart 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 1mo ago.
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.
How it starts
The opening of the file, as written. The whole thing — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Clear flowcharts and walkthroughs
Help the reader answer a concrete process question. Preserve the user's requested format and scope; drawing a deployment does not authorize deploying it.
Choose the right representation
- Establish the audience, the question, the process boundaries, and whether the diagram describes current behavior or a proposal. Infer these from available context before asking questions.
- Use a small static flowchart when labeled steps and arrows answer the question. Mermaid is useful for diagrams kept as text; verify its syntax against the renderer version when needed.
- Use editable draw.io or Lucidchart documents when the user wants to maintain the diagram in that tool. Do not replace their chosen format with HTML.
- Use an HTML walkthrough when stepping, selecting scenarios, or inspecting details materially helps understanding. Do not add interaction only for decoration.
- If an available visualization skill owns the requested inline surface, follow its rendering contract. Otherwise produce the requested file or diagram using available tools; this skill does not require a particular host or browser library.
Read references/design-and-sources.md for source-backed design decisions, format details, or interactive keyboard checks.
Establish the process before arranging shapes
- Extract real steps, dependencies, decision points, responsibilities, and outcomes from the supplied evidence. Identify missing facts rather than inventing connections.
- Distinguish chronological order from data transfers and commands. A file store does not send a deployment command merely because it appears earlier in the process.
- Identify start and finish points. Give decision exits meaningful labels, including failed or waiting outcomes when relevant to the question.
- Walk through the proposed sequence against the evidence. Preserve important branches and concurrency; do not force every process into a linear walkthrough.
Make the diagram understandable
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

flowchart is a skill published in the GitHub repository yorrick/agent-skills (11 stars, last pushed 11d ago), licensed MIT. It adds 49 tokens to every session and 1,483 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-15.
