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 | $0.00000 | $0.00282 |
| Opus 5.5 | $0.00000 | $0.00113 |
| Sonnet 5.5 | $0.00000 | $0.00056 |
| Haiku 4.5 | $0.00000 | $0.00028 |
Grade A, and why
run-context-test 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.
What it actually says
You are running an empirical test comparing .context documentation vs single CLAUDE.md.
Test Configuration
Test Case: $ARGUMENTS (e.g., "01-simple-endpoint control" or "02-auth-middleware treatment")
Parse the arguments to get:
case_id: The test case (e.g., 01-simple-endpoint)group: Either "control" or "treatment"
Instructions
-
Load the test case from
tests/cases/{case_id}.md- extract the prompt -
Load the documentation based on group:
- If
control: Readtests/fixtures/control/CLAUDE.md - If
treatment: Read all files fromtests/fixtures/treatment/.context/
- If
-
Load the project codebase from
tests/fixtures/project/src/ -
Generate code following the loaded documentation to complete the prompt task
-
Save your output to
tests/outputs/{case_id}/{group}/run-{timestamp}.md
Include in your output:
- The generated code
- Brief explanation of your approach
- Which documentation sections you referenced
Important
- Follow ONLY the patterns from the loaded documentation
- Do NOT use knowledge outside what was provided in the documentation
- Pretend you've never seen this codebase before
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.

run-context-test is a command published in the GitHub repository andrefigueira/.context (252 stars, last pushed 6mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 282 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 2026-08-30.
