…user narratives Integrates npm/GitHub token budget tool landscape research into a new docs/token-budget.md. Defines two primary user narratives (all-free-tier and all-lowest-paid-tier across Claude Code / Codex / Antigravity) and maps wtcraft's layer-2 architecture position against layer-3 observability tools (CodeBurn, llm-token-tracker) and Anthropic's native Task Budget API. https://claude.ai/code/session_01A5oU4c7YSGpwatMA2PK1AE
Adds a new `wtcraft cost [--all]` subcommand that reads ~/.claude/projects/**/*.jsonl and aggregates token usage (input, output, cache_read, cache_write) and estimated USD cost by git branch. No API key or proxy required — purely local JSONL parsing. Default view filters to branches visible in the current repo's active worktrees. --all shows every branch on record. Implemented in src/wtcraft/_cost.py (Python); _cli.py intercepts the `cost` argv before delegating to bash, so the shell script needs no JSON parsing. Help text added to shell script for `wtcraft help cost`. https://claude.ai/code/session_01A5oU4c7YSGpwatMA2PK1AE

How
wtcraft costworksReads Claude Code's local JSONL session files — no API key, no proxy. Matches sessions to branches via the
gitBranchfield already embedded in each record. Pricing table is bundled in_cost.pyand covers Sonnet / Opus / Haiku (mid-2026 rates).The command is intercepted in
_cli.pybefore the bash exec, so it runs in pure Python with no shell-level JSON parsing.Test plan
