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 | $0.00116 | $0.08125 |
| Opus 5 | $0.00058 | $0.04063 |
| Sonnet 5 | $0.00023 | $0.01625 |
| Haiku 4.5 | $0.00012 | $0.00813 |
Grade A, and why
obsidian-heatmap 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 11d 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 — 594 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Obsidian heatmaps
Two complementary tools cover almost every heatmap need in Obsidian:
-
Heatmap Calendar plugin (Richardsl) — GitHub-style year overview, one call from a
dataviewjsblock. Handles 365-day grid, month labels, weekday rows, today border, color gradients, click/hover. Use this first when the question is "did I do X on each day of the year". -
Custom DataviewJS heatmaps — anything the plugin cannot draw: weeks × 7 days for the last N weeks, rows × cols matrix (e.g. metrics × weeks), rows × N days (projects × dates), custom score functions, multi-metric tooltips, streaks. The plugin draws a year; custom DOM draws whatever shape you need.
Pick the plugin first; drop to custom only when the year frame is wrong or you need a non-calendar shape.
Decision: which heatmap
| Need | Tool |
|---|---|
| One year, one metric, "did I do X today" | Plugin |
| One year, two-three metrics overlaid by color | Plugin (multi-color entries) |
| Last N weeks (e.g. 14), GitHub-contribution shape | Custom DataviewJS — weeks × 7 days |
| Rows × cols matrix (metrics × weeks, projects × months) | Custom DataviewJS — grid |
| Rows × days (projects × dates with sticky row labels) | Custom DataviewJS — activity grid |
| Cell holds an emoji / number / link, not just intensity | Plugin (content field) or custom |
| Multiple years on one screen | Two plugin blocks, one per year |
| "Cell is a task you can click" | Custom DOM with click handlers |
If the user shows a GitHub contributions screenshot — that is the last 53 weeks scrolling shape, not a calendar year. The plugin always renders Jan 1 → Dec 31 of year. For a rolling-N-weeks contribution graph use the custom pattern.
Part A — Heatmap Calendar plugin (Richardsl)
Repo: Richardsl/heatmap-calendar-obsidian. Install via Community plugins in Obsidian. Exposes a single global function on plugin load.

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.
- 11d ago First seen · 594 lines · 116 tokens per session scan A 971a91da9fbb
obsidian-heatmap is a skill published in the GitHub repository lexbritvin/obsidian-skills-pack (2 stars, last pushed 6d ago), licensed MIT. It adds 116 tokens to every session and 8,125 once invoked, about $0.0006 per session on Opus 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.
