Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

obsidian-tasks-cli 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 3d 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.

The opening of the file, as written. The whole thing — 255 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Managing Tasks via CLI

Use the obsidian CLI to read and update tasks. Obsidian must be running.

Start with simple CLI commands. Only use obsidian eval when you need filtering that CLI flags can't express (by priority, dates, tags, or custom logic).

Listing Tasks

obsidian tasks todo                    # all incomplete tasks
obsidian tasks done                    # completed tasks
obsidian tasks todo format=json        # JSON output for parsing
obsidian tasks verbose                 # grouped by file
obsidian tasks todo total              # count only
obsidian tasks todo path="Projects"    # filter by folder
obsidian tasks todo file="Shopping"    # filter by file name
obsidian tasks daily todo              # tasks from daily note

JSON output shape:

[
  {
    "status": " ",
    "text": "- [ ] Buy groceries 📅 2025-04-10",
    "file": "Projects/Shopping.md",
    "line": "12"
  }
]

Status characters: " " = TODO, "/" = IN_PROGRESS, "x" = DONE, "-" = CANCELLED.

Updating Tasks

obsidian task path="note.md" line=12 toggle      # toggle status
obsidian task path="note.md" line=12 done         # mark done
obsidian task path="note.md" line=12 todo         # mark todo
obsidian task path="note.md" line=12 status="/"   # set in-progress

To add a new task to a file:

obsidian append path="note.md" content="- [ ] New task 📅 2025-04-10"

append writes whatever text you give it verbatim — match the vault's Task Format setting (Settings → Tasks → Task Format). If it's set to Dataview format, write [due:: 2025-04-10] instead of 📅 2025-04-10 (see obsidian-tasks-syntax for the full field mapping). Check taskFormat in the Tasks plugin's data.json ("emoji" or "dataview") if unsure.

Advanced Queries via Plugin API

For filtering by priority, dates, tags, or any combination — use obsidian eval to access the Tasks plugin cache. The cache holds all parsed task objects with rich queryable properties.

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.
