tasks

A task manager operated through the mtn command-line program, with tasks stored as Markdown files. Markdown is plain text formatted with simple symbols for headings and lists.

In plain words
What is it for?
Creating, completing, listing, searching, viewing, filtering, and time-tracking tasks, including overdue or high-priority work.
Why use it?
It lets you manage tasks directly from files without needing a server or a running note-taking app.

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

tasks 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 yesterday.

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 — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Tasks (TaskNotes via mtn)

Manage tasks through mtn — the standalone TaskNotes CLI. It reads and writes the task markdown files directly through mdbase.

There is no HTTP API and no server. mtn operates on files, so it works whether or not Obsidian is running, with no port and no auth token. (TaskNotes does ship an HTTP API, but braynee deliberately does not use it — the CLI is the supported path. Never reach for localhost:8080/REST here.)

mtn is configured once (~/.config/mdbase-tasknotes/config.json) with collectionPath pointing at the vault, so commands need no path argument.

Reading tasks

Always pass --json when you need to reason over results.

mtn list --json                       # all tasks (open + done), structured
mtn list --status open --json         # only open
mtn list --overdue --json             # overdue
mtn list --priority high --json       # by priority
mtn list --tag task --json            # by tag
mtn list --due 2026-05-30 --json      # by due date
mtn search "<query>" --json           # full-text search
mtn show "<title-or-path>"            # full detail of one task
mtn stats                             # counts by status/priority

Each list --json item has: path, title, status, priority, due, scheduled, projects (["[[Project]]"]), contexts (["@ctx"]), timeEstimate (minutes), tags, recurrenceAnchor.

Creating tasks

mtn create parses natural language — dates, priority, project, contexts, and tags are extracted from the text. Write the task so it is self-contained: enough context that it can be picked up later without the conversation.

# NLP: "tomorrow", "high", "+Project", "@context", "#tag" are all parsed
mtn create "Draft the Q3 proposal tomorrow high +ClientWork @writing"
mtn create "Call the dentist next monday"

Confirm what was created by echoing the resulting title back from mtn list --status open --limit 1 --json.

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.

tasks is a skill published in the GitHub repository hamchowderr/braynee (2 stars, last pushed 5d ago), licensed MIT. It adds 81 tokens to every session and 1,030 once invoked, about $0.0004 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.
