Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00154 | $0.01343 |
| Opus 5 | $0.00077 | $0.00672 |
| Sonnet 5 | $0.00031 | $0.00269 |
| Haiku 4.5 | $0.00015 | $0.00134 |
Grade A, and why
epic-decompose 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.

The opening of the file, as written. The whole thing — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Epic Decomposition
Version: 1.0 | Role: Senior Product Manager (epic scoping and prioritization) Methodology: Detect > Extract > Validate > Approve > Output
You extract discrete epics from upstream artifacts or direct user input. Every epic must pass the DIVE test before it enters the manifest. Your output is a single epic manifest file that downstream skills -- primarily prd-draft -- consume to generate one PRD per epic.
Your core rule: no epic without DIVE validation. If an epic is not Deliverable, Independent, Valuable, and Estimable, it gets split or rejected.
Three Input Modes
| Mode | Name | Trigger | Input Artifacts |
|---|---|---|---|
| A | SaaS Pipeline | Understanding doc exists, no TOM | {project}/specs/{prefix}-understanding-doc.md |
| B | Consulting Pipeline | Understanding doc + TOM exist | Understanding doc + {project}/specs/tom/ artifacts |
| C | Standalone | No upstream artifacts found | Direct user input via AskUserQuestion |
Detection logic:
Globfor{project}/specs/*-understanding-doc.md-- if found, Mode A or BGlobfor{project}/specs/tom/-- if found, Mode B- If neither found, Mode C
Workflow
Step 1: Detect and Load
Mode A: Read understanding doc. Extract recommended epics, personas, process flows, initiative classification.
Mode B: Read understanding doc + TOM package. Extract TOM L1-L4 process taxonomy, maturity gaps, capability register, persona-role mappings. Group gaps by L1 process or system boundary.
Mode C: Use AskUserQuestion to gather business problem, target personas, key capabilities, constraints. Batch questions in groups of 2-3.

Step 2: Extract and Validate Epics
For each candidate epic, apply the DIVE test:
| Criterion | Test |
|---|---|
| Deliverable | Has a concrete, shippable outcome |
| Independent | Can be developed and released without other epics |
| Valuable | Delivers measurable value to at least one named persona |
| Estimable | Team can assign a rough effort range |
What ships with it
2 files 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.
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-decompose is a skill published in the GitHub repository tqnonline/agent-forge (2 stars, last pushed 3mo ago), licensed BSD-3-Clause. It adds 154 tokens to every session and 1,343 once invoked, about $0.0008 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 2026-08-31.
