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 | $0.00038 | $0.01920 |
| Opus 5 | $0.00019 | $0.00960 |
| Sonnet 5 | $0.00008 | $0.00384 |
| Haiku 4.5 | $0.00004 | $0.00192 |
Grade A, and why
dimensional-analysis 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 today.
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.

Dimensional analysis
Contract
| Field | Bound contract |
|---|---|
| Trigger | A financial, scientific, DeFi, blockchain, or off-chain codebase contains mixed units, fixed-point precisions, scaling factors, rates, prices, shares, or conversions and needs full annotation plus validation. |
| Authority | Reversible local: writes only comment-only dimensional annotations in in-scope source files plus DIMENSIONAL_SCOPE.json, DIMENSIONAL_UNITS.md, and a findings report in the project root; rollback is version control (revert comments) or undo (delete the three generated artifacts). No remote mutation. |
| Side effect | Comment-only annotations in all in-scope source files; DIMENSIONAL_SCOPE.json, DIMENSIONAL_UNITS.md, and a final findings/coverage report in the project root. No executable code, types, or logic are changed. |
| Done | Every in-scope file has terminal annotation, propagation, and validation status; no PENDING entries remain; blocked files reconcile exactly; only comments changed; confirmed and refuted mismatches are separated. |
Inputs
- Project root path (required).
- Optional pre-existing DIMENSIONAL_UNITS.md and DIMENSIONAL_SCOPE.json for reuse, only when their
project_rootmatches this repo and they contain the required structure. - No mode argument is honored; the full four-phase pipeline always runs end to end.
Procedure
- Bound scope. Confirm the project root. Identify every file containing numeric arithmetic with mixed units, precisions, scaling factors, rates, prices, shares, or conversions, and prioritize each as CRITICAL, HIGH, MEDIUM, or LOW. Write
DIMENSIONAL_SCOPE.jsonto the project root withproject_root,in_scope_files(all priorities),discoverer_focus_files(narrowed to CRITICAL/HIGH only when more than 50 arithmetic files are found),recommended_discovery_order, and every in-scope file initialized tostep2: "PENDING",step3: "PENDING",step4: "PENDING". If no arithmetic files exist, write an empty manifest and skip to Output with zero findings. Done when:DIMENSIONAL_SCOPE.jsonis written with every in-scope file initialized to PENDING, or an empty manifest is written with zero findings.
What ships with it
1 file 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.

dimensional-analysis is a skill published in the GitHub repository OutlineDriven/outline-driven-development (52 stars, last pushed today), licensed Apache-2.0. It adds 38 tokens to every session and 1,920 once invoked, about $0.0002 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 2026-09-03.
