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 | $0.02591 | $0.02591 |
| Opus 5.5 | $0.01036 | $0.01036 |
| Sonnet 5.5 | $0.00518 | $0.00518 |
| Haiku 4.5 | $0.00259 | $0.00259 |
Grade A, and why
context-cli CLAUDE.md 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.

Context CLI v2.0.0 — CRITICAL CONTEXT
Scoring: Content=40 | Robots=25 | Schema=25 | llms.txt=10 (total=100)
Bots: GPTBot, ChatGPT-User, Google-Extended, ClaudeBot, PerplexityBot, Amazonbot, OAI-SearchBot + 6 more

CURRENT PHASE: 2.0.0 (Rebrand — pivot from Context CLI to Context CLI)
AGENT TEAMS: MANDATORY for ALL phases. No exceptions. See "Agent Teams" section below.
Session Workflow (MANDATORY — enforced by hooks)
- TEST — Write comprehensive tests FIRST (TDD, 100% coverage)
- CODE — Implement minimum to pass tests
- REFACTOR — Clean up: split large files (>300 LOC), extract modules, simplify
- LINT — Auto-lint via PostToolUse hook on every file change
- VERIFY —
pytest --cov=context_cli --cov-fail-under=100(100% mandatory) - COMMIT —
git add+git commit+git push origin main(every green feature) 6.5. README — If releasing a version: update README Features, CLI Usage, and Bots sections - VERSION — Patch bump + tag + push when feature is significant
- CONTEXT — Check /context; if >70% →
/compact8.5. AGENTS — If session resumes with active worktrees: check agent branches for commits, merge completed work, clean up worktrees
Versioning
Minor bump per phase: 0.3.0(A1) → 0.4.0(A2) → 0.5.0(A3) → 0.6.0(A4) → 0.7.0(B0) → 0.8.0(B1) → 0.9.0(B2) → 0.10.0(B3) → 0.11.0(B4) → 0.12.0(B5) → 1.0.0 → 2.0.0(Rebrand)
Patch within phases (2.0.1, 2.0.2, ...). Every v* tag auto-publishes to PyPI.

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.

context-cli CLAUDE.md is an instructions file published in the GitHub repository hanselhansel/context-cli (4 stars, last pushed 7mo ago), licensed MIT. It adds 2,591 tokens to every session, about $0.0104 per session on Opus 5.5. A static security scan graded it A with 0 findings.
