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 | $0.00000 | $0.00267 |
| Opus 5 | $0.00000 | $0.00133 |
| Sonnet 5 | $0.00000 | $0.00053 |
| Haiku 4.5 | $0.00000 | $0.00027 |
Grade A, and why
spec 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 5d 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.

No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
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.

spec is a command published in the GitHub repository vignesh2027/claude-best-practice (5 stars, last pushed 7d ago), with no licence file. It costs nothing until one of its globs matches a file; then it loads 267 tokens. 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.

profile
Coordinate a reproducible Java profiling and optimization lifecycle.
update-issue
Update an issue description with structured, evidence-backed content.
session-start
Thin wrapper (GETSITREP-10) — orientation logic (reading MANIFEST.md/STATUSREPORT.md/PROJECTPLAN.md/.sitrep-data.json, building the summary) lives entirely in getsitrep session-start. This file's only job is to invoke it and show the result — it does not re-read those files or re-derive the summary itself.
handoff
Thin wrapper (GETSITREP-10) — generating sitrep/HANDOFF.md (archiving the previous one first), tailoring to a human or AI audience, and committing all live in getsitrep handoff.
review-code
Agent review pass plus manual checklist for correctness, security, performance, and accessibility.
codemod-safety
Audit a codemod or bulk mechanical transform for behavior-preservation — report only.
