A Jira epic health check. An epic is a large piece of work that is usually split into smaller issues; the check reviews its definition, breakdown, progress, and execution risks.

In plain words
What is it for?
Use it to assess an epic, find risks, and produce prioritized recommendations for improving its readiness and delivery.
Why use it?
It helps identify an epic that is unclear, poorly divided, blocked, stale, or missing important ownership and planning details.

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

check-epic 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 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/fetch_epic.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Tool

Run this script using the Bash tool:

bash .claude/skills/check-epic/scripts/fetch_epic.sh <EPIC_KEY> --json
  • EPIC_KEY: the Jira epic key (e.g. FBX-1234) — may be resolved from a phrase; see Epic Key Resolution below
  • If EPIC_KEY is not an Epic, the script exits with an error. Report the error to the user and stop.

The script outputs JSON with this structure:

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
