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 | $0.00812 | $0.00812 |
| Opus 5.5 | $0.00325 | $0.00325 |
| Sonnet 5.5 | $0.00162 | $0.00162 |
| Haiku 4.5 | $0.00081 | $0.00081 |
Grade A, and why
landforge 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.
How it starts
The opening of the file, as written. The whole thing — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
Guidance for Claude Code working on this system (the landing-generation toolkit itself).
Human overview: README.md. Decisions: docs/adr/.
What this is
A content-management / generation system for static landing pages, delivered as Claude Code skills + deployment infra. Not a build-tooling project (no bundler, test runner, lint).
Hard invariant: a landing is a static HTML file with content in the markup and zero JS on the critical path (CSS/JS inlined). Crawlers must see real content, not an empty root. Every generator and skill must preserve this.
Skills (.claude/skills/)
new-landing— landing from a brief (contract + skeleton +check_landing.py).landing-experiment— A/B on one URL (inline split, no cloaking), variant tracking, card.landing-journal— audit journal:experiments/journal.jsonl+journal.md+ git. Log every meaningful action viascripts/log_event.py.landing-ads— UTM, ad copy, keywords, editor exports →ads/<campaign>/(artifacts only).init-landing-system— deploy this whole system into another project (snapshot + sync + user-level install).
MCP server (mcp/)
The toolbox is also exposed as an MCP server (ADR-0002) — any MCP host can call it, not only
Claude Code. Thin wrapper: each tool runs the same .claude/skills/*/scripts/*.py via subprocess
(one source of logic). Validators / journal / UTM as tools; contract, brief schema, skeleton
and journal as resources; brief interviewer / generation / A/B checklist as prompts.
Transport stdio; optional dependency (Python ≥ 3.10, mcp); the
static-HTML invariant is untouched. New skill script → add a matching tool (keep CLI↔MCP parity).
See mcp/README.md.
Infra & deployment
.github/workflows/deploy.yml routes by branch: main → prod (indexable); dev → staging
(noindex); any other → preview (noindex). Server runs Traefik + two nginx containers; only prod
is indexed (X-Robots-Tag: noindex on staging via nginx). Infra values are {{PLACEHOLDER}}s
(domains/containers/dirs) — substituted by init-landing-system or by hand
(.claude/skills/init-landing-system/reference/placeholders.md). Deploy secrets: DEPLOY_HOST,
DEPLOY_USER, DEPLOY_SSH_KEY, DEPLOY_KNOWN_HOSTS.
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.

landforge CLAUDE.md is an instructions file published in the GitHub repository monthu56/landforge (11 stars, last pushed 4mo ago), licensed MIT. It adds 812 tokens to every session, about $0.0032 per session on Opus 5.5. 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.
