second-brain-os: Skill for Codex

.agents/skills/to-tickets/SKILL.md

to-tickets is a skill for Codex from the-sid-dani/second-brain-os. It costs 80 tokens per session (1,642 once invoked), scanned A, original, MIT.

A ticket-writing workflow that turns a specification, plan, or conversation into small work items. Each item describes a usable slice of work and names the items that must be completed first.

In plain words
What is it for?
Use it to break down software work or other deliverables, including preparation tasks and documentation work.
Why use it?
It replaces a large, vague task with an ordered set of concrete tickets and makes dependencies visible.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is the-sid-dani/second-brain-os's own configuration. It tells Codex how to work on second-brain-os itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything second-brain-os configures →

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

to-tickets 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 7d 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 — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.

To Tickets

Break a spec, plan, or conversation into a set of tickets. Each ticket is a tracer-bullet vertical slice that declares the tickets that block it. The work can be code or knowledge work.

Resolve the project, its tracker and its paths from docs/agents/project-context.md. If a skill earlier in this conversation already resolved them, reuse that.

Process

1. Gather context

Work from whatever is already in the conversation. If the user passes a reference as an argument, read its full body. The reference can be a spec path or a ticket file.

2. Explore (optional)

If you haven't already, look at the current state of the work.

  • Code: explore the codebase.
  • Knowledge work: read the project folder and any earlier version of the artifact.

Ticket titles and descriptions use the project's own vocabulary (CONTEXT.md or glossary.md) and respect its recorded decisions.

Look for prep work that makes everything after it easier. "Make the change easy, then make the easy change."

  • Code: prefactoring.
  • Knowledge work: gathering the data, getting access, building the doc skeleton, pulling last year's version.

3. Draft vertical slices

Break the work into tracer bullet tickets.

  • Each slice cuts a narrow but COMPLETE path through every layer. It's vertical, NOT a horizontal slice of one layer.
    • Code: schema, API, UI, tests.
    • Knowledge work: one section fully drafted, sourced and reviewed, never "write all the intros" then "add all the numbers".
  • A completed slice is demoable or verifiable on its own. Someone can check or sign off on it alone.
  • Each slice is sized to fit in a single fresh context window.
  • Any prep work comes first, as its own ticket.

Single artifacts with stages are the knowledge-work exception. One video or one deck has stages that are horizontal by nature: research, script, record, edit, package. Stage tickets are fine, but each stage must end in something a person can review on its own: the brief approved, the script and title shortlist approved, the rough cut watched, the final passing its packaging check. A stage that ends in nothing reviewable gets merged into the next one.

Changes

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.
