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 | $0.02664 | $0.02664 |
| Opus 5 | $0.01332 | $0.01332 |
| Sonnet 5 | $0.00533 | $0.00533 |
| Haiku 4.5 | $0.00266 | $0.00266 |
Grade A, and why
obsidian-tasks-caldav 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 12d 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.

CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Also read AGENTS.md for standard Obsidian community plugin conventions (file structure, manifest rules, security, UX guidelines, coding conventions). This file covers project-specific instructions.
Project Overview
This is an Obsidian community plugin that provides bidirectional sync between obsidian-tasks and CalDAV servers. Built with TypeScript, bundled with esbuild.
Development Commands
npm run dev- Start development with watch modenpm run build- Production build with type checking (tsc -noEmit -skipLibCheckthen esbuild)npm run lint- Run ESLint with Obsidian plugin rulesnpm test- Run all tests (unit + E2E) with coverage. Work is done when this passes.npm run test:watch- Watch mode for unit tests onlynpm run version- Bump version numbers in manifest.json and versions.json
Coding Standards
TypeScript
- No
any— use proper types,unknown, or type assertions with explanations - No floating promises — always
await,void, or.catch()promises - No unnecessary type assertions — only cast when the type actually changes
- Async functions must use
await— if a function doesn't await, don't mark itasync
UI Text
- Sentence case everywhere — headings, buttons, notices, command names
- Correct: "Sync with CalDAV now", "View sync status"
- Wrong: "Sync With CalDAV Now", "View Sync Status"
- See Obsidian style guide: https://help.obsidian.md/style-guide
Clean code
- Self-documenting — if code needs a comment, rename the variable or extract a method instead
- Push logic to the edges — filtering, ID resolution, data shaping belong in adapters and I/O layers, not the orchestrator
- One intent per line — each line in an orchestrator method should express a single, clear action
- No inline noise — Notice calls, counting loops, string formatting go into private helpers
- Methods as documentation —
getOrSeedBaseline()reads better than a 6-line if/else with a comment - No special-case accumulation — if you find yourself adding "also include X when Y", question whether the abstraction is right
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.

obsidian-tasks-caldav CLAUDE.md is an instructions file published in the GitHub repository josecoelho/obsidian-tasks-caldav (42 stars, last pushed 23d ago), licensed MIT. It adds 2,664 tokens to every session, about $0.0133 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 2026-08-30.
