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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00026 | $0.01053 |
| Opus 5 | $0.00013 | $0.00526 |
| Sonnet 5 | $0.00005 | $0.00211 |
| Haiku 4.5 | $0.00003 | $0.00105 |
Grade A, and why
engineering-standards 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.
How it starts
The opening of the file, as written. The whole thing — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Clean Code Methodology
The design and implementation bar for planner, implementer, and code-reviewer.
Core Philosophy
- Hickey: simple immutable data and pure functions.
- Carmack: direct implementation with a way to measure performance.
- Armstrong: isolate failures so one module cannot propagate faults.
- Knuth: clarity before cleverness.
- Liskov: honor contracts;
skills/solid/SKILL.mdowns LSP/SRP. - Ousterhout: deep modules with simple interfaces; keep complexity inside.
Weigh benefit against maintenance, runtime, false-positive, and cognitive costs. Apply Rule of Three: tolerate second duplication; extract on the third.
Code Comments
These rules govern source comments; review findings use skills/conventional-comments/SKILL.md. Comments never explain WHAT code does. Permit only non-obvious WHY—constraints, workarounds, surprising requirements—when names, structure, and tests cannot carry it.
- Rewrite first. Before adding a comment, try a named function or variable.
- No ticket/issue IDs, plan/slice/phase markers, or doc-section references. A public upstream-issue URL that is itself the why is allowed; internal trackers and pipeline artifacts are not.
- No process narration. State current code constraints. Never mention dates, corrections, edit history, users/prompts, review feedback, ticket discussion, or agent instructions. “Previously,” “Originally,” “As of,” “Correction,” “Temporary fix from,” and “This was changed because” are detection hints, not the rule.
- Document deliberate constraints. Name the consequence of removing odd code: API limits, compatibility, security, performance, ordering, concurrency, or framework behavior.
- Be local, concise, precise, verified. Use symbols/stable identifiers, not line numbers or layout. Never say only “handle edge case.”
- Do not duplicate types, tests, names, or public docs. Link an external spec only for a precise contract.
- No commented-out code. No TODO/FIXME in delivered code. Deferred work belongs in the implementer report.
- Remove obsolete comments in the same diff; preserve repo style.
- The why-only rule covers in-body comments. Doc comments on exported/public interfaces must add contract facts absent from the signature; restating a signature is a WHAT comment.
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.

engineering-standards is a skill published in the GitHub repository bostonaholic/team (11 stars, last pushed today), licensed MIT. It adds 26 tokens to every session and 1,053 once invoked, about $0.0001 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 2026-08-30.
