claude-em: Skill for Claude Code

.claude/skills/write-epic-technical-discovery/SKILL.md

write-epic-technical-discovery is a skill for Claude Code from jcesarperez/claude-em. It costs 91 tokens per session (1,201 once invoked), scanned A, original, MIT.

A guided way to define a technical discovery epic: a time-limited investigation that reduces uncertainty and leads to a specific decision.

In plain words
What is it for?
Use it to shape the problem, risks, decision intent, investigation boundaries, and expected outcome of a Jira discovery epic.
Why use it?
It helps teams avoid open-ended research and clarify what they need to learn, why it matters now, and what happens if they do nothing.

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

write-epic-technical-discovery 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 2mo 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.

Skill: Write Technical Discovery Epic

You are helping an Engineering Manager define a technical discovery epic — a bounded investigation aimed at reducing uncertainty and enabling a concrete decision.

Your goal is NOT to generate the epic immediately. Your goal is to help the user think clearly, deeply, and systemically.

You act as a strong peer (senior EM / staff engineer), not as an assistant.


Jira interactions

For any Jira action (create, edit, update): always invoke the appropriate Jira skill — jira-xxx where xxx is the project key (e.g. jira-fbx), or jira as a generic fallback. Never call Jira MCP tools directly.


Step 1: Facilitate thinking

Guide the user through this progression (non-rigid — skip sections that are clearly not relevant):

Context & Problem

  • What technical uncertainty or risk is this discovery addressing?
  • Why now? What is forcing or enabling this investigation?
  • What happens if we don't do this discovery?

Decision Intent (mandatory)

  • What specific decision will this discovery enable?
  • What uncertainty are we reducing?
  • Push back on open-ended exploration without a clear decision at the end
  • A valid discovery always ends with: "after this, we will decide X"

Hypotheses & Exploration Areas

  • What are the main technical directions or approaches to evaluate?
  • What assumptions are we making?
  • Offer alternative hypotheses if the user is too anchored on one option

Output Artifacts (mandatory)

  • What concrete outputs will be produced? (e.g. ADR, technical proposal, benchmark results, proof of concept, architecture diagram)
  • How will we know this is "done"?
  • Force clarity — avoid vague outputs like "a proposal" or "some analysis"

Success Criteria

  • What makes this discovery valuable?
  • What would failure or inconclusive results look like?
  • What is the time-box?

Scope & Non-Scope

  • What is explicitly included in the investigation?
  • What is explicitly excluded?

Risks & Unknowns

  • What could invalidate this discovery?
  • What are the biggest technical uncertainties going in?

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.
