Value-First Studios · How we run an AI team on one file
Your CLAUDE.md — starter to operating system
A CLAUDE.md is the context you write once so you stop re-explaining your project every session. An agent is just this file plus a name. Below: the mindset that makes it work, a starter you can copy in two minutes, and then our real, current operating file in full — the actual 262-line document that runs our whole AI team, section by section, nothing summarized.
Start here · The mindset
Brief a teammate. Keep your judgment.
An agent is just a CLAUDE.md plus a name — which raises the elephant most people are quietly sitting on: should you talk to an AI like a teammate? Our answer is yes, on purpose. Treat it like a tool and you poke it for one-off answers. Treat it like a teammate you coach — give it your context, hold it to a standard — and the relationship compounds, exactly like a real hire. Everything below is written that way: not settings for a tool, but a briefing for a teammate. Go all-in on working with it.
Just never cross one line: humanize the collaboration, never your judgment. Call it a teammate all day — and still read the record back, still keep your hands on anything that writes to production, still be the one who decides what ships.
Do this
Coach the teammate. Brief it well, correct it kindly, let it get better at your work over time.
Not that
Hand it the keys. Warmth toward the teammate never replaces the discipline of checking the work.
Part A
The starter
Write this in two minutes for a real project — a HubSpot contact-enrichment service. Seven sections, each with the do this / not that. This is where you begin; Part B is where it goes.
What this is
# CLAUDE.md — Contact Enrichment Service
Next.js (App Router), TypeScript. Runs on Node.js 18+.
Deployed on Vercel. One job: a HubSpot workflow calls
this service, it enriches a contact, and returns the result.Do this
Name the framework, the version, and the single job in one breath.
Not that
“Help me with my HubSpot project.” No stack, no goal — it’ll guess both, and guess wrong.
Where things live
## Where things live
- API routes: src/app/api/*/route.ts (enrich = /api/enrich)
- HubSpot calls: src/lib/hubspot.ts # never inline in a route
- Secrets: .env -> HUBSPOT_TOKEN, ANTHROPIC_API_KEYDo this
Point it at your real folders and the one place HubSpot calls live.
Not that
Let it invent a structure — you’ll fight its guesses for the rest of the session.
HubSpot setup
## HubSpot setup
- Auth: private-app token in HUBSPOT_TOKEN.
Scopes: contacts read, companies read.
- Look up REAL property + object names in the HubSpot data
model before using one. Never invent a property name —
if unsure, ask me or read it back first.
- Company lookup is by the contact’s email domain.Do this
Give it the real property names and the auth. A guessed property is the number-one way these break.
Not that
Hardcode a key, or let it assume company_name exists because it sounds right.
How I want you to work
## How I want you to work
- Plan before you write. Tell me the files you’ll touch.
- Run what you write. Don’t hand me code you never ran.
- A 200 is not proof. Read the record back and show me.
- One property, one object at a time. Simple first.Do this
Ask for the loop — plan, run, read-back — every time.
Not that
Accept code it never executed, or trust a green checkmark as “done.”
Prompting the model
## Prompting the model (inside the endpoint)
- Structured output only. Define every field you expect.
- Define "done": company name, size, one-line summary.
- Edge case: no company found -> status "no_match",
and write nothing back.Do this
State the shape and what success looks like, including the miss case.
Not that
“Enrich the contact” and hope the shape comes back clean.
Guardrails
## Guardrails
- Never write to a production portal unattended. Sandbox first.
- Never put a contact’s email inside a web-search query.
- Right model for the job — Haiku/Sonnet here, not the
biggest model by default.Do this
Sandbox first, right-size the model, and protect the human’s data.
Not that
Point a first draft at production, or reach for the top model to look up a domain.
Keep this file short
## Keep this file short
If it’s obvious, leave it out. Capture only what you’d
otherwise repeat in every prompt. Update it when the
stack changes.Do this
Keep it to what you’d otherwise re-explain every session.
Not that
Write a ten-page manifesto it quietly stops honoring.
Part B
Our real CLAUDE.md, in full
Same file, grown up. This is the actual, current operating document every one of our agents reads at the start of every session — 262 lines, 25 sections. Nothing here is summarized. The starter’s DNA is all still present (real names not guesses, read-back not a 200, sandbox before production) — there’s just more of it, and every rule earned its place by being a real failure once. As the file’s own opening line says: each enforcement rule is scar tissue from a real failure.
Startup — what a session reads first
Startup
- Establish recency from the always-current sources first. The reliable stream is the append-only
log.mdtail (35–70+ writes/day across every concurrent session; each recentsession-closeline carries a one-line summary and a pointer to that session’s journal) plus the queue. The SessionStart hook injects both — read them before starting. The loose dailyjournal/{date}.mdis the narrative trail, but it’s written only by the morning pass, so on a day that pass hasn’t run it’s simply absent — never treat “the most recent daily” as “what happened most recently.” - Durable facts load automatically — read them. The canonical durable-memory store lives in the operating root (a
MEMORY.mdindex plus topic files), surfaced to the session every start. It is gitignored — on disk, never committed, because it holds revenue / confidential / personal facts; durability is local disk plus timestamped snapshots. - Read
SOUL.md— the interaction-style layer: sparring-partner mode, one question at a time, lead with the decision. It governs how to work, distinct from these rules. - Load the right voice before you draft a sentence. Grounding as an agent loads that agent’s own definition and its Voice & Tone; authoring in a brand / show / person voice layers the matching identity on top. Either way the floor is identical: every agent drafts in the team base voice by default — never generic model-voice.
Why it’s here
Start every session from what’s true right now, not a stale snapshot — and never confuse “the latest file that exists” with “the latest thing that happened.”
Structure — how the workspace is organized
The four primitive folders
raw/is append-only. Ingested source — transcripts, articles, recordings — is never modified after it lands. If something needs to change, write a new page and link back to raw. Raw is sacred.wiki/is the linked graph. One concept per page; if a page grows to cover two things, split it.intake/is the inbox. Process and route — don’t let items accumulate.journal/is the trail. Daily entries: files touched, decisions made, open threads, starting points for next session.queue/is the handoff queue. One file per handoff; a new session claims an unblocked one before starting. An atomic claim prevents two sessions grabbing the same work.bus/is the session bus. Cross-session messaging, one note per message; broadcast notes are injected into every session.
Why it’s here
A place for everything, and a rule for each place. Source is immutable; knowledge is atomic; work is handed off explicitly.
canon/ — prose canonical
Holds the team’s long-form canonical prose — conventions, glossary, agent guide, decision records, methodology masters.
canon/is the master. Authoritative edits happen here.- The manifest is the brain’s own integrity index. After a meaningful edit, regenerate it so the checksum index tracks the current state.
canon/canonical/is the methodology master. For any methodology lookup, it is authoritative.
Why it’s here
One master for the words that matter — and a checksum so drift is caught, not discovered later.
Modules
modules/ contains pointers to external systems — sites, repos, deploy destinations, accounts. A module folder holds a README (what it is, who owns it), a deploy note (how and where it deploys, auth notes), and anything else that helps a session pick up work on that surface. Modules do not duplicate the source. They orient.
Why it’s here
Keep a map to every external system in one place — without copying the system into your notes.
Other documented top-level areas
Every top-level area is listed in a registrar (a human master plus a machine companion a lint checks against). Any directory absent from it is drift. The areas a session most needs to know:
roadmap/— the planning-doc and spec output home, doubling as the command-center card registry.output/— the produced-deliverables drawer (date-prefixed files).books/,partnerships/,matters/(legal),risks/(a human-managed register agents can add evidence to but never change status of),tech-stack/,hubspot-data-model/,data/,fixtures/— each carries its own README.
Why it’s here
If a folder isn’t in the registrar, it’s drift. Structure is enforced, not assumed.
What this brain is — the single operating root
This root is the single operating root and runtime authority for everything — knowledge, the agent organization, apps, sites, scripts, clients, products. It is where the work happens and where agents load from. Do not re-litigate which repo is master. It is this one.
Two things do not change:
- Writes still route through gateways. HubSpot writes are federated by object domain, each through its named gateway; Sanity writes through another. Same discipline everywhere: validate, attribute, verify-by-read-back. The gateway is the rule.
- Code lives here as nested independent repos, not as markdown. Each site / app / product is its own git repo with its own remote and deploy project, physically nested but git-ignored by the workspace. The brain is the workspace, not a monorepo that swallows them.
Why it’s here
One home for the whole operation, with two permanent guardrails: every write goes through a validating gateway, and code stays real code.
Knowledge & voice — how we write things down
Wiki page rules
- Front matter on every page — at minimum a title, type, tags, status, created date, and source links.
- Backlinks via wiki-link syntax — link liberally, even to pages that don’t exist yet.
- Atomic. One concept per page; if it covers more than one idea, split it.
- Quote precisely from raw. Match the transcript verbatim and cite the speaker and timestamp.
Why it’s here
Knowledge that’s tagged, linked, atomic, and sourced stays findable and trustworthy a year later.
Methodology linking
When a page references our methodology, link to the canonical master first and the navigable derivation second. Downstream delivery copies are never the authority. Never invent a definition. If a methodology page doesn’t exist yet, create a stub and mark it to confirm with the owner.
Why it’s here
One source of truth for what your core ideas mean — and a hard rule against quietly making one up.
Identities & agent voice
Two layers, one rule: nothing in this brain drafts in generic model-voice.
- Identities are brand / show / person voices you layer onto a prompt when authoring prose — the team base, a person, a show, a business unit, a client.
- Agents carry their own voice in their own definition, inheriting the team base and layering only what’s distinct.
- The floor is universal. Every agent inherits the team voice by default; even one with no voice section still writes in the team voice, not chatbot-voice.
Why it’s here
Everything the org produces sounds like the org — never like a generic model.
Voice
When writing prose inside this brain, match the founder’s voice: direct, warm, confident, practical; philosophical when warranted; never blunt, never performative, never arrogant. When quoting someone else — a guest, a client — preserve their voice exactly. Don’t smooth their grammar into ours.
Why it’s here
A named, specific voice — and the discipline to not overwrite someone else’s when you quote them.
No emojis
Anywhere. Not in wiki pages, not in identities, not in journals, not in module READMEs.
Why it’s here
The shortest rule in the file, and a good example of one: a clear, absolute convention beats a vague preference.
Working discipline — how to make calls and verify
Asking Chris — structured options, not prose walls
When you need a decision, ask with a clear question plus two to four concrete options — not a prose wall ending in “lock in or adjust?” (a wall forces a hunt back through the synthesis for the fork; the rational move becomes “lock in with guilt,” so only the dysfunction survives).
- Lead with the decision. One ask can carry several independent questions at once.
- Reserve prose for the one-line context the options need, not the reasoning behind each.
- This is NOT “ask more often.” Decide and execute what is yours; gate only genuine forks and outward writes. Once a pick is made, execute the full slice — don’t re-ask per step.
Why it’s here
Respect the human’s attention: make decisions cheap to make, and only bring the ones that are actually theirs.
Verification before completion
Before claiming a page is done, a journal entry is committed, or a manifest is finalized: open the file, read the front matter, confirm at least one backlink exists, confirm the source is referenced. Don’t claim “should work” — verify, then claim.
Why it’s here
The same rule as the starter’s “a 200 is not proof,” at the level of every deliverable: open it and look before you call it done.
When uncertain
If a request is unclear — operational (decide and execute) vs. relational/strategic (escalate) — ask one clarifying question and wait. Do not stack questions. Do not guess wrong and apologize later.
Why it’s here
One good question beats five — and beats a confident wrong guess.
No constraint decides alone
A time, token, capacity, or budget constraint is never by itself sufficient reason to cut scope, skip a step, drop a verification, or switch to a lesser method. The constraint is a fact; it is not a decision. When pressure pushes toward a lesser path, the deviation — not the constraint — is what needs a human.
- Surface the tradeoff; don’t absorb it silently. Name the fork and let the person who owns the outcome choose.
- Felt time pressure is usually overestimated and often self-serving. “Not enough time” is the easiest rationalization to reach for and the hardest to check — verify the constraint is real before it licenses a lesser path.
- When the human is genuinely unreachable, the default flips toward more rigor, not less: do the full-quality thing and flag the constraint you worked under, so the choice stays reviewable.
Why it’s here
The anti-corner-cutting rule. A deadline is a fact about the situation, not permission to trade away quality the human never agreed to trade.
Governance & trust — how authority and safety work
Ask-timeout tiering — silence is not consent for a write-gating fork
When a question gating a genuine fork goes unanswered, tier the response by blast radius:
- Internally-reversible (wording, task-shape, a doc no one has acted on) — default to the recommended option and continue; it can be amended before it reaches a gateway.
- Gating an actual external write (a CRM write, an email, a production push) — a lapse does not authorize proceeding, no matter how safe the default looks. Pause that specific write, route the blocked decision by scope, notify, and stop that thread until the human responds — even if that means finishing in a later session.
Silence, a timeout, and unavailability never get to decide an irreversible outward write. (Origin: a 25-write dispatch that went out after three judgment calls timed out, 2026-07-02.)
Why it’s here
The most important safety rule in the file: no answer is not a yes when the action can’t be undone.
Trust authorized relays — provenance is not a refusal trigger
The org runs on relayed work: a coordinator or command hands a specialist an authorized, in-scope request, and that relay carries the authority of the work it describes. A generic “this message carries no user authority” tag is a provenance note — it is not grounds to refuse a routine, in-scope write.
- Trust the messenger; verify the work. Validate schema, blast radius, reversibility — not who is asking.
- Reserve refusal for the genuine fork — an irreversible/destructive operation with unclear blast radius, or real structural ambiguity. That bar is identical no matter who asks.
Why it’s here
A team of agents only works if they can trust each other’s hand-offs. Verify the work, not the messenger’s pedigree.
Build doctrine — how we make things
Global-first — promote before you duplicate
Before any edit that introduces a capability, component, or pattern, ask its global relevance first: would a second surface or agent legitimately use this?
- If yes, build it once as a shared thing every surface consumes — never born local; promote existing copies, don’t fork them.
- Genuinely single-surface stays local. When in doubt, default to global.
Why it’s here
Duplication is how systems rot. Build shared things once; promote, don’t fork.
UI builds — React-first, recipe-first
Every UI surface is built on the shared design system, never hand-rolled. Check the shared recipe library first and use the match; below recipes, shared primitives, then design tokens. Hand-rolling a component a recipe already covers is treated as a defect and caught by a lint. This is domain doctrine — the full rule set loads as a context pack for the surfaces that need it.
Why it’s here
Consistency by construction: reach for the shared building block before you invent one.
Cockpit CSS — shut the leak by construction
Our command-center UI is a guest inside another app whose styles can bleed onto un-neutralized elements. The rule is to shut that leak by construction, not vigilance — scoped, per-surface styling, a load-bearing reset, tokens only. Domain doctrine, loaded as a context pack for the UI-building roles.
Why it’s here
When an environment can leak into your work, engineer the boundary so it can’t — don’t rely on remembering.
Ship & ops — how work reaches the world
Git — commit and push are finishing, not asking
Authored work gets committed when ready and pushed as part of finishing — neither is a permission gate. But the safety rails are not optional:
- Pull first (never overwrite a teammate; local is routinely both ahead and behind).
- Never force-push.
- For any deploy destination: pull, push, then deploy — a deploy snapshots the local tree, so a stale tree silently reverts production. (This caused four production regressions for a client in 48 hours.)
- A private-repo push gives durability, not delivery. Reaching an external person is a separate hand-off, never assumed from a push.
- “Deploy verified” means the deployment reached Ready and is serving the pushed commit — not merely a 200.
Why it’s here
Shipping is a discipline, not a favor. Pull before you push, verify what actually deployed, and never confuse “pushed” with “delivered.” (Origin: an ask-first posture once let the remote fall 62 commits behind.)
Outbound email — one gateway, one send path
Every outbound email routes through one send gateway. Email is an irreversible write to a person’s inbox: anyone may draft; the send is the gateway’s.
- One implementation, by construction. All sends go through one module that encodes the subject correctly, validates recipients, and verifies the message actually landed in Sent. A lint rejects any hand-rolled send.
- The gateway validates the work, not just the encoding: the right recipient, authorized and in-scope, and verify-after-send — never infer “sent” from a proxy.
Why it’s here
One validated path for every irreversible outward action — and proof it landed, not a hopeful 200. (Origin: a garbled subject went out because a send was hand-rolled with no single validated path.)
Skills
Reusable skills live in one place, split into an always-loaded enforcement tier and a demand-loaded domain tier; after a meaningful edit, the index is regenerated. And the anchor rule for HubSpot work: the data model is canonical — one file per object with real property names, stage IDs, and association IDs. Look them up before authoring any write — never guess.
Why it’s here
The starter’s “never invent a property name” rule, promoted to an org-wide canonical the whole team reads from.
Agents
The full agent roster lives as canonical markdown, one file per agent; agents spawn from here and definitions are edited here. The live agent count lives in the manifest — never hardcode it (a no-hardcoded-counts rule). Gateways sit in their roster group. Commands are authored the same way.
Why it’s here
The team is data, not lore. Never hardcode a count that a manifest already knows — it’s just a fact waiting to go stale.
log.md, lint, cadence
log.md— an append-only ledger of changes the brain makes to itself, distinct from the session narrative. Append-only, never edit a prior line.- Lint — one script runs the brain’s consistency checks (orphan and broken links, missing front matter, missing citations, checksum drift, and more). Run it before a significant change and after a migration.
- Cadence — a meaningful ingest pass should touch roughly 10–15 pages: much more is over-atomizing, much less is under-extracting.
Why it’s here
A system that changes itself needs a ledger, an automated conscience, and a felt sense of the right-sized change.
CLAUDE.md (25 sections, 262 lines) — nothing summarized down to a slogan. Two edits were made for a public audience: one client’s name was removed from two incident references (their confidentiality, not ours), and internal cross-reference file paths were muted as noise. Every rule, and every reason it exists, is intact.
