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 | $0.00035 | $0.00757 |
| Opus 5.5 | $0.00014 | $0.00303 |
| Sonnet 5.5 | $0.00007 | $0.00151 |
| Haiku 4.5 | $0.00003 | $0.00076 |
Grade A, and why
d2 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 — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.
D2 Diagram Standard
D2 remains an installed specialist tool. Mermaid is the default for portable GitHub and Slidev diagrams; use D2 when its composition, styling, boards, or layout control materially improves the result.
Use D2 When
- The repository already owns
.d2sources. - The diagram needs bespoke composition, nested containers, multiple boards, scenarios, layers, or steps.
- A standalone SVG, PNG, PDF, PPTX, GIF, or ASCII export is the primary deliverable.
- Mermaid cannot express the visual clearly without renderer-specific workarounds.
Use Mermaid for the ordinary case and LikeC4 for a durable multi-view architecture model.
Workflow
-
State the visual thesis, target medium, and expected reading size.
-
Write the smallest readable
.d2source. Prefer containers, explicit directions, and short labels over manual coordinates. -
Start with the default
dagrelayout. Tryelkonly when it produces a materially clearer topology; inspect supported engines withd2 layout. -
Use a built-in theme as the base and override its tokens only for brand compliance. Discover current theme IDs with
d2 themes. -
Apply the Fmind palette and font guidance from fmind-theme when appropriate.
-
Format, validate, and render:
d2 fmt diagram.d2 d2 validate diagram.d2 d2 diagram.d2 diagram.svg -
Trust the command exit status, not only the presence of an output file; D2 can leave a partial render after an error.
-
Inspect the real export for clipping, crossings, font fallback, contrast, appendix behavior, and whether links or tooltips survive the target embedding method.
Output Rules
- Prefer SVG for web pages and documentation. Use PNG only for raster-only destinations.
- Supply the four
--font-*flags together when using custom TTF fonts so missing weights do not silently fall back. - PNG and PDF exports may require Playwright/Chromium; keep browser dependencies project-local when reproducibility matters.
- If D2's bundled Playwright download is unavailable, keep the successful SVG export and rasterize it with the project's reviewed browser toolchain instead of weakening validation or pinning an obsolete browser.
- Keep
.d2beside every generated artifact. Do not treat an exported image as the editable source. - Use Mermaid instead when the source must render natively in GitHub or be embedded directly inside Slidev Markdown.
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.

d2 is a skill published in the GitHub repository fmind/dotfiles (4 stars, last pushed 1mo ago), licensed MIT. It adds 35 tokens to every session and 757 once invoked, about $0.0001 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 2026-08-31.
