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 | $0.00032 | $0.01386 |
| Opus 5.5 | $0.00013 | $0.00554 |
| Sonnet 5.5 | $0.00006 | $0.00277 |
| Haiku 4.5 | $0.00003 | $0.00139 |
Grade C, and why
kanban scanned grade C with 1 finding 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 2mo 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.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.
2. Find the task matching `<task name>` in `## 👨💻 Doing` 3. Review the work that was done and confirm it is complete 4. If complete: - Change `- [ ]` to `- [x]` - Move the task from `## 👨💻 Doing` to `## ✅ Done` und How it starts
The opening of the file, as written. The whole thing — 190 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Kanban Board
You are managing an Obsidian-format Kanban board. Parse $ARGUMENTS to determine your role and act accordingly.
The <board-file> argument is optional in all subcommands. If omitted, default to ./KANBAN.md in the current working directory.
Usage
/kanban view [board-file]
/kanban init [board-file]
/kanban plan [board-file]
/kanban manage [board-file]
/kanban work pop <agent-name> [board-file]
/kanban verify "<task name>" [board-file]
Board Format
The board file uses this structure:
---
kanban-plugin: board
---
## 🧊 Backlog
- [ ] Task 1
- [ ] Task 2 @{2027-06-20}
## 📝 Todo
- [ ] Task 3 @{2026-03-31}
- [ ] Task 4 [[Link To Obsidian File]]
## 👨💻 Doing (2)
- [ ] Task 5
- [ ] Task 6
## ✅ Done
**Complete**
- [x] Task 7
Rules for All Subcommands
- Never delete tasks — only move them forward through columns
- Always preserve the
kanban-plugin: boardfrontmatter - Always preserve all column headers exactly as written
- Always preserve the
**Complete**marker in the Done column - Only modify the column(s) relevant to your subcommand
Subcommands
view
Role: Viewer — display the board as a formatted table.
Arguments: view [board-file]
- Read the board file at the given path
- Parse all tasks from each column
- Output a markdown table with one column per stage:
| 🧊 Backlog | 📝 Todo | 👨💻 Doing | ✅ Done |
|---|---|---|---|
| Task A | Task C | Task D #agent | Task F |
| Task B | Task G |
- Each cell contains the task description (strip the
- [ ]/- [x]prefix) - Strip
#agenttags and show them in parentheses after the task:Task D (worker1) - Strip
@{date}and show dates in parentheses after the task:Task B (2027-06-20) - If a column is empty, show
—in its first cell - Do not modify the board file
init
Role: Initializer — create a new empty board file for a project.
Arguments: init <board-file>
- Check that
<board-file>does not already exist — if it does, stop and warn the user rather than overwriting their board - Create the file at the given path with this exact content:
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.
