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 | $0.00944 | $0.00944 |
| Opus 5 | $0.00472 | $0.00472 |
| Sonnet 5 | $0.00189 | $0.00189 |
| Haiku 4.5 | $0.00094 | $0.00094 |
Grade A, and why
Standby.Design 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.
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.
CLAUDE.md
Operational knowledge for agents working in this repo. Architecture lives in CONTEXT.md, product strategy in STRATEGY.md — read those for the what; this file is the how-to-not-get-stuck.
npm publish (standby-design-mcp)
-
The npm account uses passkey 2FA — there are no TOTP codes. npm's browser auth flow requires a real TTY; from an agent session shell,
npm publishfails (EOTP) and masks the auth URL. Never try to publish from the session shell, and don't send the user to a terminal. Instead, open a visible window on the user's desktop:Start-Process powershell -ArgumentList '-NoExit','-Command','Set-Location "C:\Users\karst\Documents\Repositories\Solopreneur\Standby.Design\packages\mcp-server"; npm publish'The browser opens, the user confirms the passkey. If they check "do not challenge for 5 minutes", follow-up publishes from the session shell work without a prompt — useful for quick re-publishes.
-
Version bump touches three places:
package.json(version),src/server.ts(SERVER_VERSION),server.json(versionandpackages[0].version). -
mcpNamein package.json must stayio.github.KarstenKreh/standby-design-mcp— case-sensitive and must exactly match thenamein server.json, or the MCP registry rejects the publish. -
MCP registry update after an npm release:
mcp-publisher login github(device flow, user confirms code) thenmcp-publisher publish. Binary: GitHub releases ofmodelcontextprotocol/registry(mcp-publisher_windows_amd64.tar.gz). Registry description max 100 chars.
Deploys (website + remote MCP server)
bash deploy.shdeploys everything (site +standby-mcpcontainer for mcp.standby.design). SSH auth runs through the 1Password SSH agent — there is no key file on disk. The user may need to confirm a 1Password popup; if auth fails, checkssh-add -Land the whitelist in%LOCALAPPDATA%\1Password\config\ssh\agent.toml.- The script must use Windows OpenSSH (it prepends the PATH itself) — Git Bash's bundled ssh cannot reach the 1Password agent pipe.
- Never pipe
deploy.shthroughtail/headin a background task. Those buffer until EOF, so the log stays empty for the whole run and the deploy looks hung when it is only building images on the server (several minutes, normal). Run it bare and read the output file as it grows. Before blaming SSH, verify withssh -v -o BatchMode=yes -o ConnectTimeout=10 [email protected] 'echo ok'— that fails fast instead of waiting on a prompt. - New root-level static files (
public/*.html,*.txt) also need aCOPYline in the rootDockerfile, or they 404 in production while working locally.
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.

Standby.Design CLAUDE.md is an instructions file published in the GitHub repository KarstenKreh/Standby.Design (1 stars, last pushed 1mo ago), licensed MIT. It adds 944 tokens to every session, about $0.0047 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.
