GitHub Issues are +derived artifacts of `docs/ISSUE_PLAN.md` + `docs/issues/*.md`. + +--- + +## 1. Product definition + +`worklog` is a **local-only, read-only CLI** that generates a daily work +report (日報) and a standup report from activity traces already present on the +machine: + +- zsh command history, +- git commit history across local repositories, +- AI coding agent session logs (Claude Code, Codex CLI). + +Reports are rendered as Markdown to stdout (default) or to a file. An +**optional local LLM** (OpenAI-compatible endpoint on loopback) turns the +deterministic facts into a natural-language narrative; when the LLM is +unavailable or disabled, the deterministic report is the complete product, not +a degraded one. + +Written in Go, distributed as a single static binary, intended for public +open-source release. + +### 1.1 Requirements baseline (user-approved 2026-07-10) + +| Topic | Decision | +|---|---| +| Summarization | Local LLM included in v1 (opt-out), deterministic rendering is the base and fallback | +| Sources (v1) | zsh history + git + Claude Code + Codex CLI; other agents = extension interface only | +| LLM connectivity | OpenAI-compatible API, **loopback-only, enforced in code**; non-loopback unsupported in v1 | +| Report types | `daily` + `standup` | +| Output | stdout default; optional file output | +| Secrets | Redaction ON by default, applied before rendering and before any data reaches the LLM; agent sessions contribute metadata by default, raw prompts opt-in | +| Language | Go; minimal dependencies | +| Report languages | Japanese and English templates in v1 | + +### 1.2 Hard product invariants + +These are non-negotiable properties. Every issue that touches them carries +matching acceptance criteria; CI enforces them where mechanically possible. + +- **I1 — No external network I/O.** The process never opens a network + connection to a non-loopback address. The only network feature is the local + LLM client, restricted to loopback by a custom dialer. Proxy environment + variables are ignored. No telemetry, no update checks, no DNS lookups + except for the LLM endpoint host (whose resolved IPs must all be loopback). +- **I2 — Sources are read-only.** Files and directories being read are never + created, modified, locked, or deleted. Git is invoked only with read-only + commands and `--no-optional-locks` (plus `GIT_OPTIONAL_LOCKS=0`). No + `git status` (it may refresh the index). Files are opened `O_RDONLY`. +- **I3 — Writes are confined** to (a) an explicit user-given output path or + the configured output directory, (b) the worklog config file written by + `worklog init` only. v1 keeps **no state, no cache, no log files**. +- **I4 — Redaction by default.** Secret masking is applied to all source + content before aggregation, rendering, and LLM submission. Disabling it + requires an explicit flag/config and prints a warning banner. +- **I5 — Untrusted input discipline.** All source file content is untrusted: + parsers are tolerant (skip-and-count, never crash), bounded (line/file + caps), and content is sanitized (control characters stripped) before it can + reach a terminal, a file, or the LLM. + +## 2. v1 scope + +### 2.1 In scope + +- Subcommands: `daily`, `standup`, `init`, `doctor`, `sources`, `version`. +- Sources: zsh (extended-format timestamps required for date filtering), git + (multi-repo discovery + commit extraction), Claude Code sessions, Codex + sessions. +- Redaction engine with built-in ruleset + user-extensible patterns. +- Deterministic Markdown rendering, Japanese + English templates. +- Optional loopback LLM narrative with graceful fallback. +- File output with safe-write semantics. +- macOS + Linux. CI on both. + +### 2.2 v1 non-goals (explicit) + +- Windows support. +- bash/fish history parsing. +- Web/browser enrichment ("browser search" extension idea) — recorded as a + v2+ extension direction; v1 core must not depend on it. +- Custom user templates, HTML/PDF output. +- Incremental state, caching, daemon/watch mode, scheduling (use cron/launchd + externally). +- Reporting uncommitted changes (`git status` conflicts with I2). +- Multi-machine aggregation. +- Plugin execution (subprocess source providers) — interface boundary is + designed (§6.1) but no dynamic loading/exec ships in v1. +- Holiday-calendar awareness for standup (weekend skip only). +- Auto-detected "blockers" content (placeholder section + optional LLM + suggestions only). + +### 2.3 Deferred v2 ideas + +Weekly/monthly rollups; bash/fish; Gemini CLI and other agents; subprocess +plugin protocol for third-party sources; template overrides; Obsidian +frontmatter/properties mode; entropy-based redaction; holiday calendars; +Homebrew tap; signed releases (Sigstore); `~/.claude/history.jsonl` and +`~/.codex/history.jsonl` as lightweight prompt sources; browser-search +enrichment as an optional, clearly network-labeled extension. + +## 3.
