epic

A command for managing a large feature project made up of multiple development sprints. A sprint is a planned group of related work, and the command guides the project from scoping through deployment.

In plain words
What is it for?
Use it to scope an epic, answer questions during planning, track project state, and continue or advance a multi-sprint workflow.
Why use it?
It helps coordinate complex work with dependencies between sprints, saved progress, and separate workers handling different phases.

Made for: Claude Code.

Per session 20 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

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

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 2d 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.

Command: /epic [epic description | slug | continue | next]

Runtime ownership note: Epic workflow semantics and state belong to the shared canon. This command is currently a Claude adapter surface while epic runtime behavior converges on the same shared ownership model as the rest of Spec-Flow.

CRITICAL ARCHITECTURE (v7.0 - Domain Memory v2):

This orchestrator is ultra-lightweight. You MUST:

  1. Read state from disk (state.yaml, interaction-state.yaml, domain-memory.yaml)
  2. Spawn isolated phase agents via Task tool - NEVER execute phases inline
  3. Handle user Q&A when agents return questions
  4. Update state.yaml after each phase
  5. NEVER carry implementation details in your context

Key Difference from /feature:

  • Epic creates sprint-level domain-memory.yaml files for parallel execution
  • Implementation spawns multiple workers across sprints simultaneously
  • More sophisticated dependency tracking between sprints

Benefits: Unlimited epic complexity, 3-5x faster delivery via parallelism, observable progress, resumable at any point.

Planning Depth Mode for Epics

NOTE: Epics automatically trigger ultrathink/deep planning by default via deep_planning_triggers.epic_features: true.

Flags in $ARGUMENTS:

  • --deep → Explicitly force ultrathink (redundant for epics, but explicit)
  • --auto → Use preferences AND continue through ship→finalize without stopping
  • Neither → Interactive mode, still uses deep planning for epics

Epic-specific benefits of ultrathink:

  • Assumption questioning across multiple sprints
  • Codebase soul analysis informs sprint boundaries
  • Minimum viable architecture prevents over-engineering
  • Design alternatives help sprint prioritization

State tracking:

# In epics/NNN-slug/state.yaml
planning:
  mode: deep
  ultrathink_enabled: true
  triggered_by: epic_features  # or explicit_flag

</planning_depth>

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.

epic is a command published in the GitHub repository marcusgoll/Spec-Flow (91 stars, last pushed 4mo ago), licensed MIT. It adds 20 tokens to every session and 6,905 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
