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 | $0.00486 | $0.00486 |
| Opus 5 | $0.00243 | $0.00243 |
| Sonnet 5 | $0.00097 | $0.00097 |
| Haiku 4.5 | $0.00049 | $0.00049 |
Grade A, and why
pyghidra-lite 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 8d 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.

Releasing
1. Bump version
Update version in three places, keeping them in sync:
pyproject.toml(version)server.json(top-levelversionand thepackages[].version)src/pyghidra_lite/__init__.py(__version__, exposed bypyghidra-lite --version)
2. PyPI
Create a GitHub release (e.g., v0.5.0). The publish.yml workflow handles PyPI upload via trusted publishing.
3. MCP Registry
The MCP registry requires manual publish (OIDC workflow needs org-level permissions).
# First time: download the publisher
gh release download --repo modelcontextprotocol/registry --pattern 'mcp-publisher_linux_amd64.tar.gz'
tar -xzf mcp-publisher_linux_amd64.tar.gz -C .tools/
rm mcp-publisher_linux_amd64.tar.gz
# Login (opens browser for GitHub OAuth)
.tools/mcp-publisher login github
# Publish (reads server.json)
.tools/mcp-publisher publish
The CLI caches auth in .mcpregistry_* (gitignored). Subsequent publishes only need the publish command.

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.
