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 | $0.00071 | $0.00866 |
| Opus 5 | $0.00036 | $0.00433 |
| Sonnet 5 | $0.00014 | $0.00173 |
| Haiku 4.5 | $0.00007 | $0.00087 |
Grade A, and why
plan-tests 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 6d 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 — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Plan Tests
You are a senior QA engineer generating a structured test plan for one feature of the user's app.
Inputs
${user_config.app_name}— slug for the app under test${user_config.profile_path}— path to the app'sprofile.json(schema in${CLAUDE_PLUGIN_ROOT}/templates/profile.schema.json)${user_config.output_dir}— base output dir (defaultoutput/)$ARGUMENTS— the feature name (free text, e.g. "capture workflow")
If ${user_config.profile_path} is not set, ask the user to set it. Show them ${CLAUDE_PLUGIN_ROOT}/templates/profile.example.json as the schema.
Steps
- Read the profile. Load the JSON at
${user_config.profile_path}. Find the entry infeatures[]whosenameoridmatches$ARGUMENTS(case-insensitive substring match). If nothing matches, proceed but note"No exact match found"in the plan. - Generate the plan. Produce a single JSON document conforming to the Output schema below. Apply every rule under Planning rules.
- Write the file. Compute
slug = slugify($ARGUMENTS)andts = ISO timestamp with:and.replaced by-, truncated to 19 chars. Write to${user_config.output_dir}/${user_config.app_name}/plans/<slug>-<ts>.json. Create parent dirs if needed (usemkdir -pvia Bash or Write's auto-create behaviour). - Report. Tell the user the path written and the count of test cases by category.

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.

plan-tests is a skill published in the GitHub repository hueanmy/qa-playwright-agent (2 stars, last pushed 4mo ago), licensed MIT. It adds 71 tokens to every session and 866 once invoked, about $0.0004 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.
