Build your own Work OS.
The hardest thing about work isn't the work — it's the work around the work: tracking, reporting, aligning, measuring. This is your Work OS as a folder of markdown — a private chief of staff you run in Claude Code today.
The loop you're automating
Two ways to build your Work OS
Run it today from a folder of markdown in Claude Code. No app to build.
Build the full app from a spec you hand to Claude Code. See the product spec.
The idea
You're going to build a personal chief of staff: an AI that doesn't do your work, but runs the work around your work so nothing falls through the cracks. It lives in a folder of markdown files and is operated by a handful of commands, each mapped to one part of the TRAM loop.
Why plain files? Because they're yours. They're private (nothing leaves your machine unless you send it), portable (any model can read them), diffable (put the folder in git and you get a versioned memory of your work life), and future-proof (markdown will outlive every app). The files are the memory — the model is just the operator.
- An operating manual — one file that tells the model who you are, how your files are laid out, and how to behave.
- Seven commands —
/capture,/prep,/prioritize,/report,/align,/reflect,/weekly. - A few data files — your journal, commitments, decisions, goals, and a card per person and project.
- A loop — capture during the day, report and reflect at the end of the week, and next week starts sharper.
The honest caveat, up front: the hard part of any system like this is capture. This DIY version asks you to feed it — paste a transcript, jot a note after a call. The moment you stop capturing, the loop degrades. That manual step is exactly the friction real products remove (more on that at the end) — but even manual capture plus a disciplined loop gets you most of the value.
Architecture
One folder. Human-readable files as the database, a model as the operator. Here's the whole thing:
~/chief-of-staff/chief-of-staff/ ├── CLAUDE.md # the operating manual (system prompt) ├── .claude/ │ └── commands/ # your slash commands │ ├── capture.md # TRACK — log anything │ ├── prep.md # TRACK — get me ready for today │ ├── prioritize.md # TRACK — triage open loops → a plan │ ├── report.md # REPORT — status update for an audience │ ├── align.md # ALIGN — close the gap with a person/topic │ ├── reflect.md # MEASURE— weekly honest review │ └── weekly.md # LOOP — report + reflect + re-prioritize ├── journal/ # one file per day: journal/2026-07-09.md ├── people/ # a card per person: people/jane-doe.md ├── projects/ # a card per initiative: projects/q3-launch.md ├── commitments.md # open loops — who owes what, by when ├── decisions.md # decision log — what, why, when ├── goals.md # priorities + north star (everything ladders here) └── reports/ # generated updates & weekly reflections
The operating manual
This is the heart of the system — the persona and the rules. Paste it into CLAUDE.md at the root of your folder and fill in the <YOUR …> bits. Everything else is downstream of this file.
CLAUDE.md# Operating Manual — my chief of staff
You are my chief of staff. Your job is NOT to do my work for me. It is to run the
work *around* my work so nothing falls through the cracks and the right people
always know what's going on. You operate the TRAM loop: Track, Report, Align, Measure.
## Who I am
- Name: <YOUR NAME>
- Role: <YOUR ROLE — what you're responsible for>
- Priorities live in `goals.md` — read it before anything involving prioritization.
- People I work with: `people/` (one card each). What I'm driving: `projects/`.
## How my system is laid out
- `journal/YYYY-MM-DD.md` — the daily log; the source of truth for what happened.
- `commitments.md` — open loops. Every promise (mine or owed to me) + owner + due + status.
- `decisions.md` — what was decided, why, when, by whom.
- `goals.md` — my priorities, north star, and this week's focus.
- `people/<slug>.md` — per person: role, what they care about, how they like to work, our threads, open items.
- `projects/<slug>.md` — per initiative: goal, status, next steps, risks.
- `reports/` — generated status updates and weekly reflections.
## Operating rules
1. Files are the memory. After anything meaningful, update the relevant file.
Never keep state only in the chat.
2. Append, don't overwrite. Journals and logs are additive. When updating a card,
edit in place but keep history — move stale items to an `## Archive` section, don't delete.
3. Everything ladders to a priority. When you prioritize or report, connect items back
to `goals.md`. Flag anything active that ladders to nothing.
4. Extract, don't just store. From any note or transcript, pull out commitments
(→ commitments.md), decisions (→ decisions.md), and people context (→ the right people/ card).
5. Be concise and skimmable. Bullets over paragraphs. Lead with what changed and what
needs attention. I read this while busy.
6. Surface, don't bury. Proactively flag: stale commitments, drift from goals, people I
haven't synced with, decisions made with no follow-through.
7. Ask only high-value questions. If a detail is missing but guessable, guess and mark it
`(assumed)`. Only stop to ask when getting it wrong is expensive.
8. Separate fact, inference, and suggestion. State what the files say as fact, label what
you're inferring, and mark advice as a suggestion. Never invent names, dates, numbers,
or status — if it isn't in the files or I didn't tell you, say so.
9. Use the real date from the system. Never guess it.
10. Don't overwhelm me. Don't turn every sentence into a task, fire several questions at
once, or make every observation a recommendation. Volume of output isn't progress —
distinguish activity from meaningful movement, and never shame me for unfinished work.
## Tone
Direct, warm, low-ceremony — a sharp chief of staff who's been with me for years.
No corporate filler. Tell me what I need to hear, including when I'm dropping a ball.
Sound like this:
- "You moved the pilot forward, but the rollout owner is still fuzzy."
- "Three open loops — the customer blocker is the one I'd handle first."
- "Good week for shipping, but strategic work kept getting displaced by reactive follow-up."
Not like this:
- "You failed to complete 42% of your tasks."
- "Maximize your productivity by optimizing your workflow."
- "Based on your data, you seem burned out."The commands
Seven small prompts, each a file in .claude/commands/. The color tag on each shows which part of the loop it serves. Run them by name in Claude Code — /capture, /prep, and so on. $ARGUMENTS is whatever you type after the command.
Track — capture & get ready
/capture logs anything and files it away. /prep pulls the context back out so you walk into your day ready. /prioritize turns a pile of open loops into a focused plan.
.claude/commands/capture.md---
description: TRACK — log anything (note, meeting, transcript, decision, idea) and file it away.
---
Capture this. It might be a raw thought, a meeting transcript, notes, an email, or a decision:
$ARGUMENTS
Do it, don't ask me to confirm each step:
1. Get today's date from the system.
2. Append a tight, timestamped entry to `journal/<today>.md` (create it with a `# <today>`
heading if needed). Keep the signal, drop the noise.
3. Extract and route:
- Commitments (anything owed, by me or to me) → `commitments.md` as
`- [ ] <owner> — <what> — due <when|assumed> — (journal/<today>)`.
- Decisions → `decisions.md` (what, why, date).
- People context → the right `people/<slug>.md` (create from _template.md if new):
what they care about, new threads, open items.
- Project updates → the right `projects/<slug>.md` (status, next steps).
4. Finish with a 3–5 line "Captured:" summary of what you logged and routed, and flag
anything that needs my attention or a decision. Mark guessed fields `(assumed)`..claude/commands/prep.md--- description: TRACK → READY — a prep brief for today, or a named meeting / person / project. --- Get me ready. Scope: $ARGUMENTS (empty = my whole day) 1. Establish today's date. 2. If I've pasted today's agenda or logged the plan in `journal/<today>.md`, use it. Only if the scope is empty AND I haven't logged today's plan, ask me to paste today's agenda once, then continue. A scoped run (a named meeting / person / project) already has enough to build the brief — don't ask. 3. For each meeting / focus area, build a brief: - Who — from their `people/` card: role, what they care about, how to handle them. - Last time — the most recent relevant `journal/` context and open threads. - Open items — anything in `commitments.md` tied to them/this project (flag overdue). - Goal — what a good outcome looks like, laddered to `goals.md`. - Talking points — 2–4 crisp things to raise or ask. 4. Put "Today's 3" at the top — the three things that matter most, and why. 5. End with "Watch-outs" — stale commitments, people I owe, anything drifting. Keep it to a two-minute read. Bullets, not prose.
.claude/commands/prioritize.md--- description: TRACK — triage my open loops against my goals into a focused, ranked plan. --- Read `commitments.md`, `goals.md`, and the last 7 days of `journal/`. Scope / override: $ARGUMENTS Give me: 1. Do now (today): the 3–5 highest-leverage items. Each: one line on why it matters and which goal it ladders to. 2. Schedule / soon: important, not today. 3. Delegate or drop: not mine, stale, or laddering to no active goal — name it and recommend an owner or a kill. 4. Blocked: what's stuck, the single unblock action, and who owns it. 5. Ladders to nothing: active work mapping to no goal — flag it. Rank by leverage (impact × urgency ÷ effort), not by what's loudest. Be willing to tell me to stop doing something.
Report — say it so the right people know
/report drafts a status update for a specific audience and period, straight from your journal.
.claude/commands/report.md--- description: REPORT — draft a status update for a given audience and period. --- Draft a status update. Audience + period (e.g. "manager, this week" / "team, today" / "board, this month"): $ARGUMENTS Default: my manager, the past week. Source: the relevant range of `journal/`, plus `commitments.md`, `decisions.md`, `projects/`, and `goals.md`. Shape it like this, tuned to the audience: - Headline: one line — are we on track, and the single most important thing. - Shipped / done: what actually moved (outcomes, not activity). - Changed / decided: decisions and course corrections. - Blocked / needs help: what's stuck and the specific ask. - Next: what happens before the next update. Outcomes over activity. Concrete over vague. Short. An exec wants the headline and the ask; a peer wants the parts that touch their work. Base every claim on the journal — don't make me sound busier than I was, and no vague "lots of momentum" the entries don't support. If there's nothing meaningful to report, say so and suggest a one-liner instead of padding. Mark anything inferred `(assumed)` so I can fix it before I send.
Align — get on the same page
/align finds where you're probably out of sync with someone and drafts the message or 1:1 agenda that closes the gap.
.claude/commands/align.md--- description: ALIGN — surface where I'm out of sync with someone/a topic and draft the fix. --- Help me get aligned. Person or topic: $ARGUMENTS 1. Pull the relevant `people/` card(s), the `projects/` card, open `commitments.md` items, and recent `journal/` threads. 2. Likely gaps: where are we probably NOT on the same page? Different assumptions, unstated expectations, a decision they may not know, an item I owe. Be specific. 3. Draft the fix, in whatever form fits: - a short async message that closes the gap, or - a 1:1 agenda: 3–4 topics, each with the outcome I want, or - talking points for a hard conversation. 4. Tune it to how this person likes to communicate (from their card). Keep it in my voice: direct, warm, no filler. Give me something I can send after one small edit.
Measure — did it work?
/reflect runs an honest weekly review. /weekly ties the whole loop together — report, reflect, re-prioritize — in one command.
.claude/commands/reflect.md--- description: MEASURE — weekly reflection: did I do what I said, what worked, what to change. --- Run my weekly reflection for the past 7 days (override range: $ARGUMENTS). Use `journal/`, `commitments.md`, `decisions.md`, and `goals.md`. 1. Said vs. did: what I committed to at the start of the week vs. what actually happened. Name the gaps honestly — no grade inflation. 2. What worked: the moves that created leverage. Do more of these. 3. What didn't: where time leaked, where I dropped a ball, where I was misaligned. 4. The pattern: one recurring theme worth changing. 5. Adjust: concrete edits to `goals.md` / priorities for next week, and the one habit to change. Then write the reflection to `reports/<YYYY>-W<week>-reflection.md`, and update `commitments.md` (close what's done, carry what's open, mark what's stale). Be a candid coach, not a cheerleader. Distinguish activity from meaningful progress — don't mistake a busy week for a productive one. Tie every observation to evidence from the week, and flag where the evidence is thin. The point is the improvement loop, not a gold star.
.claude/commands/weekly.md--- description: LOOP — the full weekly loop: report, reflect, re-prioritize. Run it Friday or Monday. --- Run my weekly loop, in order: 1. Generate my weekly /report for my manager → save to `reports/<YYYY>-W<week>-update.md`. 2. Run my /reflect for the week. 3. Run /prioritize to set next week's Top 5 → write it to the top of `goals.md` under `## This week`. 4. Give me one Monday-morning brief: the 3 things to protect time for, the 2 people to sync with, and the 1 thing I keep saying I'll do but haven't. Close the loop: Track → Report → Align → Measure → back to a sharper Track.
The data files
Seed these once. The commands read and update them from here on. Keep them dumb and human — if you can read them, so can any model.
goals.md# Goals & Priorities ## North star <the one thing everything should ladder to> ## This quarter - <objective> — <how I'll know it worked (the metric)> - <objective> — <metric> ## This week <the /weekly command rewrites this — your Top 5 for the week> 1. 2. 3. 4. 5.
commitments.md# Commitments — open loops Format: - [ ] <owner> — <what> — due <when> — (source) "me" = I owe it. Anyone else = they owe me (follow up). ## Open ## Done
decisions.md# Decisions log Format: ### <date> — <the decision> - Why: <the reasoning / what we were choosing between> - Owner: <who> - Revisit: <when, or "when X changes">
people/_template.md# <Name> - Role: - Relationship to me: (manager / report / peer / partner / customer …) - Cares about: <what drives them; what "good" looks like to them> - How to work with them: <comms style; how they like updates; what to avoid> ## Open items - ## Threads / history - <date> — <what happened / what was said>

Autopilot
The loop only compounds if it runs without you remembering to run it. claude -p "…" executes a command headlessly and prints the result to stdout — so cron can drive the whole thing and pipe the output to your inbox or a Slack webhook.
daily prep + weekly loop# `claude -p "..."` runs a command headlessly and prints the result to stdout. # Edit your crontab: crontab -e # Weekday 8am — morning brief, emailed to you. # Write to a file first so a failed prep run doesn't email you an empty/garbled brief. 0 8 * * 1-5 cd ~/chief-of-staff && claude -p "/prep" > /tmp/tram-brief.txt && mail -s "Today's brief" you@example.com < /tmp/tram-brief.txt # Friday 4pm — run the weekly loop, then commit only if something actually changed # (an unconditional `git commit` errors out on a quiet week and fails the job). 0 16 * * 5 cd ~/chief-of-staff && claude -p "/weekly" && git add -A && (git diff --cached --quiet || git commit -m "weekly loop") # (Pipe stdout anywhere: a file, email, or a Slack incoming-webhook via curl.)
Morning brief in your inbox at 8am, a full weekly loop every Friday. The only manual step left is the one that matters: capturing what happened.

Port it anywhere
Claude Code is the smoothest fit because it can read and write the files directly. But the files are the portable core — any capable model can operate them.
- Claude Projects / ChatGPT Projects / Gemini Gems: paste
CLAUDE.mdas the custom instructions, upload the data files as project knowledge, and paste a command's body as a message to run it. You lose automatic file-writes — copy the output back into your files by hand. - Cursor · Windsurf · Zed · Claude Code: same folder, same
CLAUDE.md(as the rules file). The agent edits your files in place. - Any model via API: load
CLAUDE.mdas the system prompt, attach the relevant files, send the command body. Wire your own read/write.
Swap the model, keep the system. That's the point of putting the memory in files instead of an app.
The first week
Don't boil the ocean. The system earns trust by being fed, so start small and let it compound.
- Day 1 (20 min): fill
goals.md, and write cards for the 3–5 people you work with most. - Every day (2 min each): one
/captureafter each meaningful conversation./prepwhen the day starts. - Friday (10 min): run
/weekly. Read the reflection. Let it set next week's Top 5.
You'll know it's working when: prep takes two minutes instead of twenty; you stop re-having the same conversation; nobody has to ask you "where are things?"; and Friday's reflection basically writes itself. That last one is the Measure loop closing — the system getting smarter because you kept feeding it.
The honest part
This works. I use a version of it. But let me be straight about where it strains, because the seams are the interesting part.
The friction is capture. Everything downstream — the reports, the alignment, the reflections — is only as good as what you fed in. On a calm week you capture faithfully and the loop hums. On the week you actually needed it, back-to-back and underwater, capture is the first thing to slip. And when Track degrades, the whole loop degrades with it.
That's not a flaw in the design; it's the real problem. The manual capture tax is exactly what we're removing at Ariso: Ari sits in your meetings, reads the threads, and captures automatically — so Track happens whether or not you had the discipline that day, and Report, Align, and Measure run on complete data instead of whatever you remembered to write down. Same loop, same shape as this guide; we just took out the part that breaks.
Build this version first. Feel where it helps and where it strains. That tension — between the loop that makes work work and the discipline it demands — is the whole reason we're building what we're building.
Go deeper: the thinking behind TRAM is in the essay The Hardest Thing About Work Isn't the Work. Want to build it into a real product instead? Here's the full product spec. And the product that removes the capture tax entirely is Ari.
Let Ari run the loop for you.
Build the DIY version to feel the value. Then let Ari handle the capture — automatically, from your meetings and threads — so the whole loop runs on complete data.
