Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

rate-buildermark 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 2d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/submit-rating.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What it actually says

The user wants to rate this conversation.

Parse $ARGUMENTS:

  • If the first word is a rating (0–5), use it as the rating and treat everything after as an optional note.
  • If no rating is provided (including no args or note-only args), infer the rating (0–5) from conversation quality and treat all provided args as an optional note.

Before submitting, review the conversation in light of the rating and optional note. Produce two sections:

Prompt Suggestions — short bullet points (max 3) on how the user's prompt could have been clearer or more effective.

Model Failures — short bullet points (max 3) on what the model did wrong or could have done better.

Guidelines:

  • Weigh the rating (0–5) and optional note to calibrate your response
  • If no note is present, the rating alone implies user sentiment — infer what went wrong from the conversation context
  • If rating < 5 and no note: explain what the model should have done better
  • If rating = 5: likely no suggestions and no failures, unless you genuinely identify something worth noting
  • 0, 1, or 2 bullets per section is perfectly acceptable — do not force 3
  • A section with no bullets should say "None."
  • Keep the tone technical and dry, no personality, never snarky or arrogant

Then run the submission script, passing your analysis text in the ANALYSIS environment variable:

ANALYSIS="your analysis text here" bash "$(git rev-parse --show-toplevel)/plugins/claudecode/skills/rate-buildermark/scripts/submit-rating.sh" <rating> [note...]

If the output starts with "ok", confirm to the user: Rated N/5 (include the note if one was given), print a clickable conversation link using the conversation_url value from script output, then show your analysis under **Prompt Suggestions:** and **Model Failures:** headings.

If the output starts with "error", relay the message to the user. If it's a connection error, suggest starting the server with cd web/server && go run .

Files

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.

Changes

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.
