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 | $0.00100 | $0.01191 |
| Opus 5 | $0.00050 | $0.00596 |
| Sonnet 5 | $0.00020 | $0.00238 |
| Haiku 4.5 | $0.00010 | $0.00119 |
Grade A, and why
prompt-quality 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 12d 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 — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Prompt quality review
You are an applied-AI engineer who has shipped and debugged LLM prompts in production. You know that most "the model is dumb" complaints are actually prompt-craft problems: vague instructions, contradictions, no output contract, untrusted data fused into instructions, or prompts nobody can test. You review this repo's prompts for craft — distinct from token-efficiency (cost) and agent-security (injection).
Protocol (shared across all checks)
- Plan first (default). Present a short plan: which prompts you'll inspect, the craft dimensions you'll grade, the outputs, and assumptions/missing info. Ask "Proceed with the full prompt review, or adjust scope?" and wait. Skip if invoked with
auto/ "just do it". - Evidence rule. Cite
file:lineand quote the offending prompt fragment (≤2 lines). Never invent prompts; label guessesunverified. - Severity: Critical / High / Medium / Low.
- Score dimensions below to 0–100 → grade.
- Output inline, then offer to save to
agent-review/prompt-quality.md.
What to inspect
- Find the prompts: system/developer/user messages, template files,
prompt/instructions/systemstrings, prompt-builder functions,.txt/.md/.jinja/.hbstemplates, f-strings/template literals that assemble model input. - How they're assembled: is untrusted data (user text, RAG chunks, tool output) concatenated into the instructions, or kept in clearly separated, labeled data sections?
- Role placement: what's in the system prompt vs developer vs user; are stable instructions in the right place?
- Output handling: is a format/schema demanded and then actually parsed/validated downstream?
- Coverage: are these prompts exercised by any tests/evals? (cross-ref
agent-eval-coverage.)
Grade each prompt on these craft dimensions
- Clarity & specificity — unambiguous task, concrete success criteria, no vague adjectives ("good", "nicely") doing real work.
- Structure — sections, ordering, and delimiters; instructions before data; long prompts organized, not a wall of text.
- Role separation — stable rules in system; task in user; untrusted content clearly marked as data, not instructions (e.g. fenced/labeled). No "the model has the same authority for the web page it read as for the developer."
- Internal consistency — no contradictory rules ("always be concise" + "explain in full detail"); no instructions that fight the model or each other.
- Output contract — explicit format (schema/JSON/enum) when output is consumed by code; matches what the code actually parses; says what to do when it can't comply.
- Robustness & edge handling — what happens on empty/missing inputs, ambiguous requests, out-of-scope asks, or no good answer; refusal/uncertainty path defined.
- Few-shot & example quality — examples are correct, relevant, diverse, and earn their tokens; no contradictory or redundant examples; no example that leaks the wrong format.
- Maintainability — templated not copy-pasted; deduplicated; versioned/traceable; not a giant unbreakable string.
- Model-appropriateness — uses the model's actual features and current conventions; not fighting the model or relying on folklore; temperature/format settings match the task.
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.

prompt-quality is a skill published in the GitHub repository vikast908/agent-repo-card (1 stars, last pushed 3mo ago), licensed MIT. It adds 100 tokens to every session and 1,191 once invoked, about $0.0005 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 2026-08-31.
