To Tickets is an agent skill from bestofjs/bestofjs. Break a plan, spec, or the current conversation into a set of tracer-bullet tickets, each declaring its blocking edges, published to the configured tracker — edges as text in one file per ticket locally, or native blocking links on a real tracker.
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
The repository describes itself as: :star: A place to find the best components to build amazing web applications. The best of JavaScript! The licence is MIT.
5 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 5d82633. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
To Tickets loads about 1.4k tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 800 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/to-tickets/SKILL.md (or your agent's skills folder). This skill also uses 1 other file; get the full folder from GitHub.Break a plan, spec, or conversation into a set of tickets — tracer-bullet vertical slices, each declaring the tickets that block it.
The issue tracker and triage label vocabulary should have been provided to you — run /setup-matt-pocock-skills if not.
Work from whatever is already in the conversation context. If the user passes a reference (a spec path, an issue number or URL) as an argument, fetch it and read its full body and comments.
If you have not already explored the codebase, do so to understand the current state of the code. Ticket titles and descriptions should use the project's domain glossary vocabulary, and respect ADRs in the area you're touching.
Look for opportunities to prefactor the code to make the implementation easier. "Make the change easy, then make the easy change."
Break the work into tracer bullet tickets.
<vertical-slice-rules>
</vertical-slice-rules>
Give each ticket its blocking edges — the other tickets that must complete before it can start. A ticket with no blockers can start immediately.
Wide refactors are the exception to vertical slicing. A wide refactor is one mechanical change — rename a column, retype a shared symbol — whose blast radius fans across the whole codebase, so a single edit breaks thousands of call sites at once and no vertical slice can land green. Don't force it into a tracer bullet; sequence it as expand–contract. First expand: add the new form beside the old so nothing breaks. Then migrate the call sites over in batches sized by blast radius (per package, per directory), each batch its own ticket blocked by the expand, keeping CI green batch to batch because the old form still exists. Finally contract: delete the old form once no caller remains, in a ticket blocked by every migrate batch. When even the batches can't stay green alone, keep the sequence but let them share an integration branch that all block a final integrate-and-verify ticket — green is promised only there.
Present the proposed breakdown as a numbered list. For each ticket, show:
Ask the user:
Iterate until the user approves the breakdown.
Publish the approved tickets. How depends on the tracker /setup-matt-pocock-skills configured — the tickets are the same either way, only the shape of the blocking edges changes:
.scratch/<feature-slug>/issues/<NN>-<slug>.md, numbered from 01 in dependency order (blockers first). Each file's "Blocked by" lists the numbers/titles it depends on. Use the per-ticket file template below — one ticket per file, never a single combined file.ready-for-agent triage label unless instructed otherwise — the tickets are agent-grabbable by construction.Work the frontier: any ticket whose blockers are all done. For a purely linear chain that means top to bottom.
Do NOT close or modify any parent issue.
<local-ticket-template>
<NN> — <Ticket title>What to build: the end-to-end behaviour this ticket makes work, from the user's perspective — not a layer-by-layer implementation list.
Blocked by: the numbers/titles of the tickets that gate this one, or "None — can start immediately".
Status: ready-for-agent
</local-ticket-template>
<issue-template>
A reference to the parent issue on the tracker (if the source was an existing issue, otherwise omit this section).
The end-to-end behaviour this ticket makes work, from the user's perspective — not layer-by-layer implementation.
</issue-template>
In either form, avoid specific file paths or code snippets — they go stale fast. Exception: if a prototype produced a snippet that encodes a decision more precisely than prose can (state machine, reducer, schema, type shape), inline it and note briefly that it came from a prototype. Trim to the decision-rich parts — not a working demo, just the important bits.

Run `npx skills add bestofjs/bestofjs --skill to-tickets -a claude-code`. Or copy the skill folder (.agents/skills/to-tickets in bestofjs/bestofjs) into .claude/skills/to-tickets in your project. Claude Code loads it when a task matches its description.
Run `npx skills add bestofjs/bestofjs --skill to-tickets -a codex`. Or copy the skill folder (.agents/skills/to-tickets in bestofjs/bestofjs) into .agents/skills/to-tickets in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add bestofjs/bestofjs --skill to-tickets -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/to-tickets, .gemini/skills/to-tickets, .github/skills/to-tickets and .opencode/skills/to-tickets in your project.
SKILL.md names no scripts, command-line tools or credentials: To Tickets is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
To Tickets is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.4k tokens (SKILL.md is roughly 5.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
