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 | $0.00052 | $0.00360 |
| Opus 5 | $0.00026 | $0.00180 |
| Sonnet 5 | $0.00010 | $0.00072 |
| Haiku 4.5 | $0.00005 | $0.00036 |
Grade A, and why
decision-memo 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 10d 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.
What it actually says
Decision Memo
Workflow
- Clarify the decision to be made, decision owner, deadline, and audience.
- Separate facts, assumptions, constraints, preferences, and unknowns.
- Define 2-4 viable options, including a default or no-change option when relevant.
- Compare options using business impact, speed, cost, risk, reversibility, and operating complexity.
- Recommend one option with explicit rationale, risks, and next steps.
Output Standard
Use this structure by default:
- Decision Required: the exact choice to make.
- Recommendation: one clear recommendation and why.
- Context: relevant background and current state.
- Options Considered: options, benefits, costs, and risks.
- Tradeoff Analysis: compact comparison of the decision criteria.
- Risks And Mitigations: material risks and how to reduce them.
- Implementation Notes: owners, first steps, dependencies, and success measures.
- Open Questions: unresolved facts that could change the recommendation.
Rules
- Do not hide uncertainty. Label assumptions and missing information.
- Do not create a false consensus when stakeholder positions conflict.
- Prefer reversible, low-regret recommendations when evidence is thin.
- Make the decision path auditable enough for later review.
References
Read references/memo-patterns.md when the user asks for a one-page memo, executive committee memo, or weighted decision matrix.
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.

decision-memo is a skill published in the GitHub repository ClarentCinematics/Codex-Skills-for-Enterprise (2 stars, last pushed 2mo ago), licensed MIT. It adds 52 tokens to every session and 360 once invoked, about $0.0003 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.
Other skills, from other repositories
adapto-scaffold
Create a new Adapto-ready frontend by wrapping npx create-adapto-app — choose a framework (Next/Astro/SvelteKit), scaffold the project (the Adapto read-client is included), and wire up .env. Consent-gated — shows the exact command and runs it only after you approve. New projects only.
adapto-translate
Translate existing Adapto content (Articles, Pages, collection items, Categories, Microcopy) into another enabled language via create-translation. Structural-parity gate blocks broken translations; glossary-aware; single-item and corpus modes. Plan-then-apply; runs at the top model tier.
adapto-content-upload
Push approved content drafts to Adapto — convert each reviewed Markdown draft to HTML, create or update the Article/Page/collection item (one-way push via the ledger id-map), mirror its SEO metadata into adaptoseo, and drift-guard against out-of-band CMS edits. Schema-gated; everything lands as draft. Plan-then-apply.
adapto-project-define
Build the project's "brain" — a rich, local multi-file knowledge base — through deep guided discovery (a short skippable interview plus active web/competitor/keyword research), and store a summary in Adapto as adaptoprojectconfig so every other skill writes on-brand. Plan-then-apply; fully optional.
adapto-schema-apply
Apply an approved .adapto/schema-plan.json to the CMS — create Article categories and custom collections (with a two-pass step for references), idempotently, via the adapto CLI. Plan-then-apply; writes content. Pairs with adapto:schema-design.
adapto-microcopy
Manage UI micro copy (nav, buttons, labels, errors) as Adapto key/value/language entries. Two modes — init seeds a curated, on-brand starter set; extract scans your frontend for hardcoded strings and creates entries + a replacement guide (no source rewrite). Plan-then-apply.
