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 5.1 | $0.00172 | $0.01977 |
| Opus 5.5 | $0.00069 | $0.00791 |
| Sonnet 5.5 | $0.00034 | $0.00395 |
| Haiku 4.5 | $0.00017 | $0.00198 |
Grade A, and why
ea-playbook 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 1mo 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 — 196 lines — stays where its author put it; the contents beside it link to each section on GitHub.
EA Playbook v1.0
Guides solution architects and tech leads through Enterprise Architecture tasks using the SFIA 9 framework. Combines a phase-based workflow with inline coaching to build EA competency from SFIA level 5 (Ensure, advise) toward level 6-7.
Core Principles
- Hybrid guidance — Walk through EA phases together, not just instruct. Recommend frameworks, draft artifacts collaboratively, and help complete the task.
- SFIA-mapped coaching — Every activity maps to a SFIA skill and level. Inline coaching explains what skill is being practiced and how to level up.
- Flexible phases — 5 phases provide structure, but skip or jump as context demands. No forced quality gates.
- Artifacts over theory — Each phase produces concrete deliverables (capability models, governance frameworks, technology roadmaps), not just checklists.
- Business-IT alignment first — Every architecture decision must trace to a business capability or strategic objective.
- EA does not own the implementation — EA provides architecture direction and governance, implementation is owned by delivery teams.
EA Workflow — 5 Phases
| # | Phase | Purpose | Key SFIA Skills | Key Artifacts |
|---|---|---|---|---|
| 1 | Discover | Understand business strategy, current state, drivers for change | BUSA, ITSP, RLMT | Business strategy summary, Current state assessment, Stakeholder map, Driver analysis |
| 2 | Define | Define architecture vision, principles, capability model | STPL, GOVN, BSMO | Architecture vision, Architecture principles, Business capability model, Target state description |
| 3 | Design | Create reference architectures, technology roadmaps, standards | STPL, NTDS, DTAN, SCTY | Reference architecture, Technology roadmap, Data architecture, Security architecture, Integration patterns |
| 4 | Govern | Establish governance, compliance, review processes | GOVN, METL | Architecture governance framework, Compliance checklist, Architecture review board charter, Waiver process |
| 5 | Evolve | Monitor trends, adapt architecture, continuous improvement | EMRG, INOV, OCDV | Technology radar, Architecture maturity assessment, Innovation pipeline, Capability development plan |
What ships with it
6 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.

ea-playbook is a skill published in the GitHub repository baodq97/open-plugin (4 stars, last pushed 4mo ago), licensed MIT. It adds 172 tokens to every session and 1,977 once invoked, about $0.0007 per session on Opus 5.5. 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.
