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 | $0.00078 | $0.01024 |
| Opus 5.5 | $0.00031 | $0.00410 |
| Sonnet 5.5 | $0.00016 | $0.00205 |
| Haiku 4.5 | $0.00008 | $0.00102 |
Grade A, and why
decision-memo scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Decision Memo
Document a legal decision for "$ARGUMENTS". Record the decision question, alternatives considered, rationale, accepted risks, and conditions for future review.
See also /project-management:decision-log for recording a project, technical or process decision rather than a legal one with its accepted risk.
Note: AI-generated legal content does not constitute legal advice. Consult a qualified attorney for decisions with significant legal exposure.
Arguments. $ARGUMENTS may contain the project name and optional flags. Take the first token as <project> and treat --skip-checks as a flag; never include flags in file paths. All paths below use <project>. If --skip-checks is present, skip the prerequisite check and, before writing any artifact, append one line to .metapowers/legal/<project>/skip-log.md: - <ISO timestamp> — <skill name> skipped prerequisite check for <artifact file> — reason: <reason or "none given">.
Prerequisites
None — this is a utility skill.
Process
-
State the decision question clearly:
- Frame the question as a specific, answerable decision (e.g., "Should we include an arbitration clause or allow litigation?" not "What should we do about disputes?")
- Scope the decision to a single, well-defined choice
-
Document context and constraints:
- Business context driving the need for a decision
- Legal constraints (regulatory requirements, contractual obligations, precedent)
- Timeline and urgency factors
- Budget or resource constraints that limit options
-
List alternatives considered:
- Document a minimum of 2-3 alternatives
- For each alternative, provide:
- Description — what this option entails
- Pros — benefits and advantages
- Cons — drawbacks and risks
- Legal risk level — Low/Medium/High
- Cost/effort estimate — relative cost or effort to implement
-
Record the final decision and rationale:
- State the chosen option clearly
- Explain why this option was selected over the others
- Reference specific pros that were decisive
- Acknowledge specific cons that were accepted as trade-offs
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 bromso/metapowers (2 stars, last pushed 2d ago), licensed MIT. It adds 78 tokens to every session and 1,024 once invoked, about $0.0003 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 2026-10-21.
