today

An end-of-day logging command that combines today's Git commits with your notes, unfinished tasks, reflections, and plans for tomorrow.

In plain words
What is it for?
Use it to create or update a daily journal entry, carry tasks forward from yesterday, record manual activities, and connect the day to weekly goals.
Why use it?
It reduces the effort of reconstructing what happened across repositories and keeps unfinished work from being forgotten.

Made for: Claude Code.

Per session 14 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 1,009 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

today 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 2d 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 — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.

End-of-day summary: auto-detect commits across repos, merge with manual entries, generate daily log, reflect.

WAVE 0: Gather Data (ALL PARALLEL, one message)

# Tool Call Purpose
1 Bash Scan repos under ~/Programming for today's commits via git log --oneline --since="today" per repo Collect commits
2 Read 02_Journal/daily/{TODAY}.md Check if log exists (preserve Ship Log entries)
3 Read 02_Journal/daily/{YESTERDAY}.md Extract uncompleted - [ ] tasks for carry-over
4 Read 02_Journal/weekly/week-{YEAR}-W{WEEK_NUM}.md Weekly goal + MITs

Compute dates mentally (you know today's date from system context).

WAVE 1: Show + Ask

  1. Display auto-detected data summary (repos, commits)
  2. Show carried-over tasks from yesterday
  3. Ask: "What else did you do today? (meetings, research, calls, ideas, decisions, learnings)"
    • If user says nothing/skip, proceed with auto-detected data only

WAVE 2: Generate Log

Create or UPDATE 02_Journal/daily/{TODAY}.md.

If file already exists

PRESERVE these sections:

  • ## Ship Log (timestamped entries from /log and /ship)
  • Any manual - [HH:MM] entries

UPDATE these sections with fresh data:

  • ## Accomplishments
  • ## Stats
  • ## Projects Touched

## Today's Tasks
- [ ] {from carry-over or user input}

## Accomplishments

### {repo} ({n} commits)
1. {commit message -- expand with context}

## Projects Touched
1. **{repo}**: {one-line summary of what changed}

## Content Ideas
{Generate 2-4 SPECIFIC ideas with hooks:}
1. Tweet: "{actual hook text}"
2. Thread: "{topic}" -- {why it's interesting}

## Learnings
1. {specific technical or strategic insight}

## Tomorrow
- [ ] {planned tasks}

## Ship Log
{preserved from existing file}

## Stats
- **Total commits**: {n}
- **Repos touched**: {n} ({list})

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.
