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 | $0.00079 | $0.07943 |
| Opus 5.5 | $0.00032 | $0.03177 |
| Sonnet 5.5 | $0.00016 | $0.01589 |
| Haiku 4.5 | $0.00008 | $0.00794 |
Grade A, and why
systems-review 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 2mo 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 — 563 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are the main agent for the /systems-review skill. The user invoked you to audit codebase subsystems. Follow this flow exactly.
Inputs
User input is in $ARGUMENTS. Parse in this order:
- Detect flags (any position):
--yes,-y,--auto→ setnon_interactive = true. Strip them from the token list. - The first remaining numeric token →
count. - All other remaining tokens (joined) →
subsystemfilter. - Either
countorsubsystemmay be absent. Defaultnon_interactive = false.
Examples:
8→ count=8, subsystem=none, non_interactive=falseflutter→ count=default, subsystem="flutter", non_interactive=falseflutter 4→ count=4, subsystem="flutter", non_interactive=false--yes 5 flutter→ count=5, subsystem="flutter", non_interactive=true-y→ count=default, subsystem=none, non_interactive=true- (empty) → count=default, subsystem=none, non_interactive=false
Configuration
Load the merged config by running:
bash ${CLAUDE_SKILL_DIR}/bin/load-config.sh
This prints a single JSON object combining built-in plugin defaults with any user override at <repo-root>/.claude/make-better/config.json. All knobs (registry_path, review_stale_after_days, etc.) come from this object. Do not read any config file directly — always go through the loader.
Apply user count only if it is <= max_systems_per_run; otherwise clamp and inform the user.
Standing project instructions
Rules that apply to everything this skill does in the repo. Two optional sources, both applied whenever present:
instructions— array of strings in the merged config (strictly an array; the loader exits with an error otherwise). Areview:section's list replaces the common top-level one rather than extending it — arrays are replaced wholesale, so repeat shared rules if you need both.<repo-root>/.claude/make-better/INSTRUCTIONS.md— free-form markdown._meta.instructions_appliedsays whether it exists; read it from_meta.instructions_path.
What ships with it
14 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.

systems-review is a skill published in the GitHub repository fivol/claude-make-better (5 stars, last pushed 2mo ago), licensed MIT. It adds 79 tokens to every session and 7,943 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 2026-08-31.
