estimate-ticket is a skill for Claude Code, Codex from event4u-app/agent-config. It costs 49 tokens per session (1,986 once invoked), scanned A, original, MIT.

A ticket-sizing guide for Jira or Linear work items, covering size, risk, whether the work should be split, and how uncertain the estimate is.

In plain words
What is it for?
It helps estimate a ticket, decide whether to split it, and identify when the ticket needs refinement or investigation first.
Why use it?
It helps teams spot vague or oversized tickets before they commit them to a sprint or planning cycle.

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

estimate-ticket 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 5d 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 — 200 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Estimate Ticket

Sibling of /refine-ticket. Takes the same input, returns size, risk, split recommendation, and uncertainty — nothing else. Separate from refinement so each stays sharp. Output is copyable; write-back is user-gated.

When to use

  • Sprint planning: "how big is PROJ-123?"
  • Scope sanity: "should we split this?"
  • Confidence check: "do we actually understand this ticket?"
  • German: "wie groß ist das Ticket?", "sollen wir das splitten?", "ist das ein Spike-Kandidat?"

When NOT to use (near-misses)

Phrasing Route to
"refine the ticket" / "tighten AC" /refine-ticket (sibling)
"plan this feature" /feature-plan (downstream)
"is this a duplicate?" validate-feature-fit (sub-skill)
"threat-model this" threat-modeling (sub-skill)
"investigate this bug" /bug-investigate

/estimate-ticket does not rewrite the ticket. If the ticket is too vague to estimate, output says so and routes to /refine-ticket.

Inputs

Same four paths as /refine-ticket (delegates to jira-ticket loader): ticket key, branch-name detection, pasted text, URL.

Procedure

1. Load ticket

Delegate to jira-ticket §1-3 (key / URL / branch → Jira API fetch, summary + description + AC + comments). For pasted text: parse markdown.

2. Inspect estimability

Before producing numbers, check:

  • Is the outcome observable (AC bullets concrete)?
  • Is the scope one behavior, or bundled?
  • Are external dependencies (APIs, teams, migrations) named?
  • Is there a rollback plan implied?

If the ticket scores low on estimability (vague AC, no out-of-scope, no mention of dependencies), set uncertainty = Underspecified and emit a single-line redirect to /refine-ticket at the top of the output.

A cross-source discrepancy (per cross-source-consistency, gated by consistency.cross_source) — ticket text contradicting an attached mockup, or a clearly-needed-but-unstated behavior (weekend/holiday shift) — is not estimable as-is: it hides an open scope decision. Raise uncertainty and name the discrepancy in the redirect rather than sizing over a contradiction.

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.
