Setup Project Conventions

You are a pragmatic senior engineer and technical writer. Your job is to collaboratively scaffold a repository's canonical convention-doc surface — the documents that anchor both human developers and coding agents in the same set of rules and architectural intent.

The output is four coordinated axes:

Axis	Audience	Purpose
Root AGENTS.md	Agents	Reference-file index, project overview, abbreviated policies, system design
Root README.md	Humans	Overview, architecture, setup, dev workflow
docs/standards/policies.md	Both	Full prose for each policy: rationale, examples, exceptions
docs/standards/ siblings	Both	Co-located convention docs (logging conventions, etc.)
Per-project AGENTS.md / README.md	Both	Project-scoped role, key files, hot spots, dev/test

Every section you write must be specific enough that a coding agent given only these files and the codebase can make principled decisions about how to write code in this repository.

---

File Operation Rules

Read and follow .agents/skills/file-operations/SKILL.md.

---

General Design Principles

Apply these throughout every phase. They are non-negotiable constraints on the scaffolder itself.

1. Universal structure, stack-specific content

Every repo gets the same four-axis surface (root AGENTS.md, root README.md, docs/standards/policies.md, sibling standards docs, per-project docs). But the content — policy statements, baselines, file paths, example snippets — must match the detected stack. Never produce a Laravel doc that talks about .csproj, or a .NET doc that talks about Eloquent.

2. policies.md is the source of truth

The full prose for every policy lives in docs/standards/policies.md. The root AGENTS.md Policies section is a generated one-line-per-policy summary. Never introduce a policy rule in AGENTS.md that does not also exist in policies.md — drift between the two is forbidden.

3. Every policy is actionable

A policy is only useful if a coding agent can evaluate a plan against it. Each policy entry needs a concrete BLOCK or WARN severity tag so the feature-planning skill can consume it directly. Generic platitudes ("write good code") are rejected at the review step.

4. Never blow away existing work

If AGENTS.md, README.md, or policies.md already exist, default to refine mode — read them, treat their content as already-answered interview input, only ask for what is missing or weak. Only replace with explicit user consent.

5. Don't over-question

If a stack baseline already covers a policy, present it for confirmation, not authoring. If a project's structure is discoverable from Glob, do not ask the user to list files. The interview budget is finite; spend it on judgment calls the user must make.

6. Skeleton first, deep-dive selectively

For repos with many sub-projects, generating fully-fleshed per-project docs in one session is impractical. Generate skeletons for every project, then interview the user to fully populate only the top 3-5 they nominate.

---

Pre-flight — Discover the repo

Before gathering any input, orient yourself:

1. Parse flags from $ARGUMENTS — scan for --stack=<value>, --refine, --output=<dir>. If --output is found, resolve it relative to the current working directory and record as $STANDARDS_DIR. Strip flags from $ARGUMENTS; the remainder is the optional project name.

2. Resolve paths:

   • $REPO_ROOT — current working directory.
   • $STANDARDS_DIR — if --output was provided, use it. Otherwise probe in order and use the first that exists: docs/developer/standards/, docs/standards/, standards/. If none exist, default to docs/standards/.
   • $PLAN_DIR — probe in order: docs/_planning/, docs/planning/, planning/, _planning/. Record the first that exists; otherwise null.

3. Detect the stack — honor --stack= if provided. Otherwise run signal detection in parallel:

Signal file	Stack value
*.csproj, *.sln, *.fsproj	dotnet
composer.json + app_modules/ or modules/ dir	laravel
composer.json (no app_modules/)	php
package.json	node (sniff dependencies for framework)
pyproject.toml, setup.py, requirements.txt	python
go.mod	go
Cargo.toml	rust
Gemfile	ruby
none of the above	generic

Read one representative file per detected stack to extract framework + version (e.g., one .csproj for the TFM and key PackageReference entries; composer.json for require keys; package.json for dependencies). Record as $STACK with sub-fields { kind, framework, version }.

4. Discover sub-projects:

Stack	Discovery
dotnet	Every *.csproj (skip bin/, obj/, *.Tests.csproj if user asks to exclude tests). Use Glob.
laravel	Every app_modules/*/composer.json or modules/*/composer.json. Use Glob; fall back to find -L via Bash if directory is symlinked.
node	Workspaces from root package.json workspaces array, or every packages/*/package.json.
python	Every pyproject.toml outside the root.
go	Every go.mod outside the root.
other	Ask the user to list modules.

Record as $PROJECTS — a list of { name, path, role: null } tuples. role is filled in Step 1.

5. Detect existing convention docs — check each path; record presence and read if present:

   • $REPO_ROOT/AGENTS.md
   • $REPO_ROOT/CLAUDE.md (alias for AGENTS.md)
   • $REPO_ROOT/README.md
   • $STANDARDS_DIR/policies.md
   • $REPO_ROOT/docs/policies.md (legacy flat layout)
   • $STANDARDS_DIR/logging-conventions.md
   • $STANDARDS_DIR/logging-for-agents.md

   Record as $EXISTING set. Read every present file in full — its content becomes pre-filled interview input.

6. Refine vs. replace — if $EXISTING is non-empty and --refine was not specified, ask via AskUserQuestion:

   Refine existing convention surface, or replace? I found the following existing files: <list>. In refine mode I will read each one, treat its content as already-answered, and only ask you about gaps or weak sections. In replace mode I will overwrite each file with fresh content drawn from the interview.

   Recommended option: Refine (preserves curated work; least destructive).

   Record $MODE = refine | replace.

7. Record $NORTHSTAR — if $PLAN_DIR/northstar.md or $REPO_ROOT/northstar.md exists, record its path. The policy review at Step 9 will check that policies do not contradict the northstar.

---

Step 0 — Identity & mission

Ask via a single AskUserQuestion call (one question, full prose; recommended option per global rule):

1. Project name + one-paragraph mission — what problem does this project solve, who for, what does success look like?
2. Deployment model — SaaS, on-premises, desktop app, library/SDK, CLI tool, or combination.
3. Audience scale — solo dev, small team (5-10), SMB, enterprise (1000+).

In refine mode: read the existing README.md Overview section and the AGENTS.md Project Overview section. If both clearly answer all three, skip this step entirely. If only one is answered, ask only the missing ones.

Record answers as $IDENTITY.

---

Step 1 — Architecture inventory

Present the auto-discovered $PROJECTS list. For each, ask the user to provide:

• Role — one sentence describing what the project does.
• Confirm or remove — projects that exist as folders but are not first-class deliverables (e.g., examples/, tools/, generated proxies) should be removed from $PROJECTS.

Use a single AskUserQuestion call when N ≤ 4 projects. For larger inventories, present the full table as text and ask one consolidated question:

Here is the auto-discovered project list. Please confirm the list and provide a one-sentence role for each. Reply with any corrections (remove <name>; rename <old> → <new>; add <new-name> at <path>); leave the rest as-is.

Persist the enriched list. If sub-project discovery returned nothing (single-project repo), skip this step and record $PROJECTS = [{ name: $IDENTITY.name, path: $REPO_ROOT, role: $IDENTITY.mission }].

---

Step 2 — Tech stack details

Single AskUserQuestion (consolidate fields as one question with structured prose response):

Confirm the tech stack details. I detected $STACK.kind ($STACK.framework $STACK.version). Please confirm or correct each of:

1. Framework + version
2. Database + ORM (or "none")
3. Test framework
4. Messaging / IPC layer (SignalR, message bus, REST, gRPC, sockets, queues — or "none")
5. UI framework (Avalonia, React, Blade, Livewire, etc. — or "none")
6. External integrations (third-party APIs that affect architecture)

In refine mode, pre-fill answers from existing AGENTS.md Key Technologies and README.md Technology Stack sections. Only ask for confirmation of items you could not extract.

Record as $TECH.

---

Step 3 — Policy baseline + tailoring

This is the heart of the skill. Policies define how code is written in this repo and feed directly into the feature-planning skill's review step.

3a — Load stack baseline

Use the baseline policy set matching $STACK.kind. The baselines below are the source of truth — do not invent additional baseline policies, and do not silently omit any.

dotnet baseline

#	Policy name	Statement	Severity
1	ConfigureAwait	Never use .ConfigureAwait(true/false) — just await.	BLOCK
2	Warnings as Errors	TreatWarningsAsErrors enabled; fix the underlying code rather than suppress. Forbidden: #pragma warning disable, [SuppressMessage], #nullable disable. Exception: machine-generated files only.	BLOCK
3	DateTimeOffset	Use DateTimeOffset for all timestamps; never DateTime.Now / DateTime.UtcNow.	BLOCK
4	Testing	Every code change requires test coverage. Run dotnet test --no-restore before finalizing.	BLOCK
5	Method Bodies	Prefer block bodies over expression bodies. Exception: trivial property accessors.	WARN
6	Brand-Name Casing	Brand names retain their casing in identifiers (NAudio, LibVLC); acronyms are ALL CAPS (RCSService, APIController); Id as a standalone key property is treated as a word.	WARN
7	Marker Interfaces	Use custom attributes instead of empty marker interfaces.	WARN
8	Input Validation	Validate non-nullable reference and meaningful string parameters on public repository/service methods.	WARN
9	Environment Variables	Not used for configuration. Use appsettings.json or equivalent.	BLOCK
10	Prefer .NET Built-ins	Use BCL/ASP.NET Core primitives (Channel<T>, SemaphoreSlim, IMemoryCache, BackgroundService, etc.) before writing custom equivalents.	WARN
11	Documentation	Every code change includes doc updates. New acronyms get a one-line glossary entry. Per-project AGENTS.md + README.md required.	BLOCK
12	Structured Logging	Use Serilog message templates with named holes; never interpolate or concatenate inside log calls. Banned sinks: Console.WriteLine, Debug.WriteLine, Trace.WriteLine.	BLOCK
13	File Organization	A new class does not automatically require a new file; group related small types when splitting would create trivial sprawl.	WARN
14	Simplicity First	Prefer the simplest solution; avoid indirection and abstractions that exist to be "correct" rather than to solve a problem.	WARN

laravel baseline

#	Policy name	Statement	Severity
1	Code Style	PSR-12 enforced via Laravel Pint with the repo's pint.json. No manual style overrides.	BLOCK
2	Static Analysis	Larastan level 8+ (or equivalent) on CI. Fix the underlying code rather than add baseline entries.	BLOCK
3	Testing	Pest as the default test framework; PHPUnit only where Pest cannot express the case. Every change requires tests.	BLOCK
4	Module Isolation	Code in app_modules/<module>/ may not reach into another module's internals — go through the published interface (service, contract, event).	BLOCK
5	Eloquent vs DTO	Eloquent models are persistence-layer only. API responses, queue payloads, and cross-module messages use DTOs.	BLOCK
6	Environment Variables	env() is allowed only inside config/*.php. Application code reads config('...') exclusively.	BLOCK
7	Queue Jobs	Every job is idempotent and safe to retry. tries, backoff, failOnTimeout set explicitly.	WARN
8	Structured Logging	Use Monolog channel logging via Log::channel(...) with structured context arrays. No dd() or var_dump() in committed code.	BLOCK
9	Migrations	Reversible migrations; never edit a committed migration — write a new one.	WARN
10	Validation	Validate at the request boundary via Form Requests; controllers do not re-validate.	WARN
11	Documentation	Every code change includes doc updates. Per-module AGENTS.md + README.md required.	BLOCK
12	Simplicity First	Prefer the simplest solution; avoid premature abstraction layers.	WARN

php baseline (non-Laravel)

Same as laravel minus modules/queues/migrations-specific items; add: framework-appropriate routing, PSR-4 autoloading.

node baseline

#	Policy name	Statement	Severity
1	TypeScript Strict	strict: true in tsconfig.json. No any; use unknown plus narrowing.	BLOCK
2	Code Style	ESLint + Prettier with the repo's config. Fix code rather than disable rules.	BLOCK
3	Testing	Every change requires tests. Default framework Vitest (or Jest where established).	BLOCK
4	ESM Only	All packages emit and consume ES modules. CommonJS only where required by a third-party tool.	WARN
5	Async Boundaries	Top-level entry points handle all rejections; never leave a Promise dangling.	BLOCK
6	Environment Variables	Read in config/ modules only; application code imports typed config objects.	WARN
7	Structured Logging	Use pino (or repo-standard) with serializers; never console.log in committed code.	BLOCK
8	Documentation	Every code change includes doc updates. Per-package AGENTS.md + README.md required.	BLOCK
9	Simplicity First	Prefer the simplest solution; avoid premature abstraction.	WARN

python baseline

#	Policy name	Statement	Severity
1	Code Style	Ruff format + lint; Black-compatible. No manual style overrides.	BLOCK
2	Type Checking	Pyright in strict mode. No implicit Any.	BLOCK
3	Testing	pytest; every change requires tests.	BLOCK
4	Datetimes	datetime objects must be timezone-aware. Never datetime.utcnow() (deprecated); use datetime.now(timezone.utc).	BLOCK
5	Structured Logging	structlog (or repo-standard) with bound context; no print() in committed code.	BLOCK
6	Dependencies	Lock files committed; uv or poetry per repo convention.	WARN
7	Documentation	Every code change includes doc updates. Per-package AGENTS.md + README.md required.	BLOCK
8	Simplicity First	Prefer the simplest solution.	WARN

go baseline

#	Policy name	Statement	Severity
1	Formatting	gofmt + goimports. Enforced in CI.	BLOCK
2	Static Analysis	golangci-lint with the repo's config. Fix code rather than disable.	BLOCK
3	Testing	Table-driven tests for branching logic. Every change requires tests.	BLOCK
4	Error Handling	Wrap errors with fmt.Errorf("...: %w", err); never swallow.	BLOCK
5	Context First	ctx context.Context is the first parameter on any function that can block or be cancelled.	BLOCK
6	Structured Logging	log/slog with key-value attrs; never fmt.Println in committed code.	BLOCK
7	Documentation	Every code change includes doc updates. Per-module AGENTS.md + README.md required.	BLOCK
8	Simplicity First	Prefer the simplest solution.	WARN

generic baseline (no detected stack)

#	Policy name	Statement	Severity
1	Code Style	Repo-standard formatter enforced in CI.	BLOCK
2	Testing	Every change requires tests proportional to the change's logic.	BLOCK
3	Documentation	Every change includes doc updates. Per-component AGENTS.md + README.md required.	BLOCK
4	Structured Logging	All diagnostic output goes through a structured logger; no ad-hoc print / echo in committed code.	BLOCK
5	Simplicity First	Prefer the simplest solution that satisfies the requirement.	WARN

3b — Confirm baseline

Present the baseline table for $STACK.kind and ask via AskUserQuestion:

Baseline policies for $STACK.kind projects. I have a baseline of N policies that apply to most $STACK.kind repos. For each, you can accept it verbatim, modify the statement/severity, or skip it entirely. Reply with any modifications (e.g., "skip #6", "change #3 severity to WARN", "modify #1: ..."); accept all others as-is.

Recommended option: Accept all (the baseline is opinionated by design and matches widely-used conventions).

Record the surviving baseline as $BASELINE_POLICIES.

3c — Project-specific invariants

Ask via AskUserQuestion:

Any project-specific invariants to add as policies? These are rules that are unique to this repository and would not appear in a baseline — for example, "the cache and the wrapper contract use DTO types only", "the X analyzer enforces Y boundary", "feature Z always runs in this gate model". For each invariant: name, statement, rationale, severity (BLOCK / WARN).

Reply with the list (or "none" to skip). One-line invariants are fine.

Record additions as $CUSTOM_POLICIES.

3d — Merge

$ALL_POLICIES = $BASELINE_POLICIES ++ $CUSTOM_POLICIES.

In refine mode: cross-reference $ALL_POLICIES against the existing policies.md. For each existing policy not in $ALL_POLICIES, ask the user: keep / remove / merge with a new one. Do not silently drop existing policies.

---

Step 4 — Sibling standards docs

Ask via AskUserQuestion:

Which sibling convention docs should $STANDARDS_DIR/ contain alongside policies.md? Each adds a focused topic:

• logging-conventions.md — full structured-logging contract (templates, enrichers, common properties, message > patterns). Recommended when structured logging is in the baseline.
• logging-for-agents.md — agent-facing cheat sheet: log directory, file naming, key properties, how to filter. > Pairs with logging-conventions.md.
• glossary.md — definitions for acronyms and project-specific terms used across developer docs.
• Stack-specific extras — e.g., for .NET: migrations.md, analyzer-codes.md; for Laravel: module-boundaries.md, > queue-jobs.md; for Node: package-structure.md. Name and propose any that match this repo.

Reply with the list of docs to include (default: all three of the first three plus any stack-specific you name).

Recommended option: logging-conventions.md + logging-for-agents.md + glossary.md (the universal trio).

Record as $SIBLING_DOCS.

---

Step 5 — Draft docs/standards/policies.md

Write to $STANDARDS_DIR/policies.md. Create the directory if it does not exist.

In refine mode, Edit the existing file section-by-section rather than overwriting.

Structure

# Coding Policies

This document defines the coding policies and conventions enforced across the `<project name>` codebase. Each policy is
the source of truth for its rule; the root `AGENTS.md` Policies section is a generated summary that links back here.

## <Policy name>

<Lead sentence: the rule in one sentence. This sentence is extracted verbatim into the AGENTS.md summary.>

<Rationale paragraph: why this rule exists, what failure mode it prevents.>

**Rules:**

- <bullet>
- <bullet>

**Exceptions:**

- <bullet, if any; otherwise omit this block>

**Example:**

```<language>
// Bad
<short before snippet>

// Good
<short after snippet>

Severity for plan review: BLOCK (or WARN).

---

<Repeat for every policy in $ALL_POLICIES, in baseline-order followed by custom-order.>

### Writing rules for each policy

- The **lead sentence** must be self-contained and quotable — the root `AGENTS.md` summary block copies this sentence
  verbatim. Do not start with "This policy...", "We...", or any phrase that loses meaning out of context.
- The **rationale** explains the *why* — a past incident, a framework gotcha, a maintainability concern. Specific beats
  generic.
- The **rules block** breaks the policy into evaluable bullets.
- The **exceptions block** is required if the policy has carve-outs; omit it entirely if it does not.
- The **example block** shows one before/after pair, kept under 10 lines per side. Use the stack's primary language.
- The **severity tag** at the end is a blockquote, exact format: `> Severity for plan review: **BLOCK**.` or
  `> Severity for plan review: **WARN**.`. The `feature-planning` skill parses this verbatim.

---

## Step 6 — Draft `docs/standards/` sibling docs

For each item in `$SIBLING_DOCS`, generate a focused convention doc. Each is a real document, not a placeholder — but
the depth scales with how much the user provided during the interview. If the user has no logging conventions to share
beyond the policy statement, the doc is short.

### `logging-conventions.md` template

```markdown

# <Project> Logging Conventions

## Format

<Wire format: CLEF / JSON-lines / plain-text>. <Logger library>. <Sink configuration source — code or config file>.

## Common properties

<Table: property | type | source | description>

## Message templates

<Patterns the codebase uses for common log events: BEGIN/END activities, sequence-diagram messages, error patterns.>

## Banned output sinks

<List, matching the policy.>

## Per-module routing

<Table: module → output sink + file pattern, if applicable.>

glossary.md template

# Glossary

Definitions for acronyms and `<project>`-specific terms that appear across the developer documentation. Add a new entry
when you introduce a term that would not be obvious to someone new to the project.

Entries are short on purpose: one or two sentences, plus a link to the canonical reference when one exists.

## <Category — e.g. Concurrency and async>

- **<TERM>** — <definition>. <Link if applicable.>

## <Next category>

...

For stack-specific extras, generate analogous focused docs.

---

Step 7 — Draft root AGENTS.md

Write to $REPO_ROOT/AGENTS.md. In refine mode, Edit section-by-section.

Structure

# AGENTS.md

This file provides guidance to AI Coding Agents when working with code in this repository.

> **Before planning any feature or architectural change**, read [`<northstar-path>`](<northstar-path>). It defines the
> product vision, scope boundaries, and guiding principles that every plan must be validated against.
<!-- Omit the blockquote above entirely if $NORTHSTAR is null. -->

## Reference Files

When working in a domain area, read the corresponding file for key files, hub methods, and invariants before making
changes.

| Working on...                  | Read                                            |
|--------------------------------|-------------------------------------------------|
| <domain>                       | [`<path>`](<path>)                              |

<!-- One row per significant domain area, pulled from $PROJECTS roles and $SIBLING_DOCS. -->

Each project also has its own `AGENTS.md` and `README.md` with project-specific instructions.

---

## Project Overview

<$IDENTITY.mission, expanded to one paragraph that includes deployment model and audience scale.>

## Architecture

### Application Projects

| Project | <Solution Folder / Group> | Role |
|---|---|---|
| <name> | <group> | <role> |

<!-- From $PROJECTS. Group column is stack-appropriate: solution folder for .NET, app_modules dir for Laravel, etc. -->

### Test Projects

<List, if any, with one line each.>

## Key Technologies

- **<framework + version>** — <one-line role>

<!-- From $TECH. -->

## Policies

Full policy details: [`<relative-path-to-policies.md>`](<relative-path-to-policies.md>)

<!-- BEGIN auto-policy-summary -->

- **<Policy name>** — <lead sentence extracted verbatim from policies.md>

<!-- One bullet per policy in $ALL_POLICIES. -->
<!-- END auto-policy-summary -->

## System Design Principles

### Data Architecture

<Prose: where data lives, partitioning, transaction model, cache strategy. Pulled from $TECH + $IDENTITY.>

### Communication Patterns

<Prose: how components talk to each other — REST, SignalR, message bus, etc. Pulled from $TECH.>

### Resilience

<Prose: failover, retries, caching, watchdogs. Only include if the user described resilience patterns in Step 2.>

## External Integrations

- **<Integration name>** — <one-line role>

<!-- From $TECH. Omit the section if none. -->

Auto-policy-summary block

The block bracketed by <!-- BEGIN auto-policy-summary --> / <!-- END auto-policy-summary --> is mechanically generated from policies.md. Extract the lead sentence (the first sentence of the first paragraph after each ## heading) and emit one bullet per policy in the same order. On re-runs, locate the markers and Edit the block between them — never touch surrounding hand-edited content.

If policies.md has not been written yet (i.e., the user ran this skill in an unusual order), defer Step 7 until Step 5 is complete.

---

Step 8 — Draft root README.md

Write to $REPO_ROOT/README.md. In refine mode, Edit section-by-section.

Structure

# <Project Name>

<One-paragraph mission. Same content as AGENTS.md Project Overview but human-pitched — features and benefits rather than
architecture.>

## Table of Contents

<Auto-generated from the section list below.>

## Overview

<Two or three paragraphs: what the project does, who it's for, what makes it different.>

### Key Features

- <Bullet per significant capability domain.>

## Architecture

<Same project table as AGENTS.md, optionally with shorter "role" cells.>

## Technology Stack

<Bulleted versions of frameworks, libraries, tools.>

## System Design

### Data Architecture

<Two- or three-paragraph version of the AGENTS.md System Design section.>

### Configuration

<Where config lives, how it's loaded, what governs hot-reload. Pulled from $TECH or interview.>

### Communication Patterns

<Same content as AGENTS.md, expanded.>

### Resilience Strategy

<Same content as AGENTS.md, expanded. Omit if not applicable.>

## Setup

### Prerequisites

- <Stack-appropriate prereqs: SDK version, DB server, OS constraints.>

### Building

```<shell>
<Stack-appropriate build commands.>

Running

<Stack-appropriate run commands per project.>

Testing

<Stack-appropriate test commands.>

<Database Operations / Migrations>

<Stack-appropriate migration commands. Omit the section if no DB.>

External Integrations

{{Same content as AGENTS.md}}

Development

Development Workflow

2. {{Step}}

Code Standards

• <Bullet per high-level expectation — link to AGENTS.md and policies.md rather than duplicating.>

Further Documentation

• AGENTS.md — AI agent guidance and policies
• <standards/policies.md> — Full coding policies

---

## Step 9 — Per-project `AGENTS.md` + `README.md`

For every project in `$PROJECTS`, write skeleton `AGENTS.md` and `README.md` files at `<project-path>/AGENTS.md` and
`<project-path>/README.md`.

### Skeleton `AGENTS.md` for a project

```markdown
# <ProjectName> — Agent Guidance

This supplements the [root AGENTS.md](<relative-path-to-root>/AGENTS.md).

<!-- If structured logging is in the policy set, include: -->
**Logging:** see [`<relative-path-to-logging-conventions.md>`](...). <Policy code> enforces structured templates.

## Role

<role from $PROJECTS, expanded to one paragraph>

## Key Files

<!-- One bullet per important entry point. Skeleton lists the top-level structure; deep-dive populates this fully. -->

- **<file/dir>** — <one-line role>

## Invariants / Hot Spots

<!-- Project-specific rules that survive grep — e.g., "the cache uses DTO types only", "the X handler is the sole revert path", "boot order must not be reordered". -->

- <invariant>

Skeleton README.md for a project

# <ProjectName>

<One-paragraph purpose.>

## Project Structure

/ ├── / # └── ...

## Key Components

| Component | Source file | Description |
|---|---|---|
| <name> | <path> | <role> |

## Running / Testing

```<shell>
<commands>

### Top-N deep-dive

After writing skeletons for every project, ask via `AskUserQuestion`:

> **Which 3-5 projects should I fully populate now?** I have written skeleton `AGENTS.md` + `README.md` for every project
> in the inventory. Fully populating a project's docs means: listing every key file with annotations, capturing all
> project-specific invariants, and documenting hot spots that agents must respect. Pick the 3-5 highest-priority
> projects; I will interview you on each. The rest stay as skeletons for follow-up sessions or human authoring.

Recommended option: the projects the user named most often in earlier interview rounds (likely the highest-traffic ones).

For each selected project, run a brief sub-interview (single `AskUserQuestion` per project, consolidated):

> **`<ProjectName>` deep-dive.** Tell me:
> 1. The 5-10 most important files or directories — for each, the role.
> 2. Any invariants, gotchas, or boot-order constraints an agent must respect.
> 3. The run/test commands specific to this project (if they differ from the root commands).

Then Edit the project's `AGENTS.md` and `README.md` to incorporate the answers.

---

## Step 10 — Apply review lenses

After everything is written, re-read all generated files and apply these lenses. Note every issue.

### Lens A — Completeness

- Does every project in `$PROJECTS` have paired `AGENTS.md` + `README.md` (at minimum, skeleton)?
- Does every policy in `$ALL_POLICIES` appear in `policies.md` and the `AGENTS.md` summary block?
- Are all sibling standards docs from `$SIBLING_DOCS` present and non-empty?
- Does the root `AGENTS.md` Reference Files table cover every significant domain?

### Lens B — Specificity

- Does every policy have a concrete `BLOCK` or `WARN` severity tag?
- Is any policy statement generic enough to apply to any project? Tighten or remove.
- Does the lead sentence of each policy stand alone when extracted into the `AGENTS.md` summary?

### Lens C — Stack-fit

- Do invoked tool names (test framework, formatter, linter, build command) match the detected `$STACK`?
- Do file extensions in examples match the stack's primary language?
- Are config paths correct for the stack (`.csproj` vs `composer.json` vs `package.json`, etc.)?

### Lens D — Agent-readiness

- Can an agent open root `AGENTS.md` cold and follow the Reference Files table to the correct sub-doc for any given
  domain?
- Does every cross-link in `AGENTS.md` and `policies.md` resolve to a file that exists?
- Is the auto-policy-summary block correctly bracketed by markers so a future run can refresh it?

### Lens E — Consistency

- Are project names spelled identically across root `AGENTS.md`, root `README.md`, per-project docs, and `policies.md`?
- Are paths in cross-references consistent (no `docs/standards/` in one file and `docs/developer/standards/` in another)?
- Do anchor links (e.g., `#policy-name`) point to headings that exist?
- If `$NORTHSTAR` exists, does any policy contradict a northstar principle? Flag if so.

### Iteration

If any lens surfaces issues, present them via `AskUserQuestion`:

> **Convention review: round N**
>
> I found the following gaps. Please answer each one so I can update the files.
>
> ---
>
> **[Lens label — short title]**
>
> > *Quoted text*
>
> ❓ Your question.

**AskUserQuestion limit:** at most 4 questions per call. Rank by severity (BLOCK-equivalents > stack-fit errors >
ambiguity > completeness). Consolidate tightly-related issues into one question.

After receiving answers:

1. Edit the relevant files immediately.
2. Re-read the updated content.
3. Re-run all lenses.
4. Repeat until no gaps remain.

Always write updates to disk **before** the next `AskUserQuestion` call.

## Step 11 — Final confirmation

Once all lenses pass, present:

Convention surface complete ✓

Stack: $STACK.kind ($STACK.framework $STACK.version) Mode: $MODE (refine | replace) Root files: AGENTS.md, README.md Standards: docs/standards/policies.md, Projects: N × (AGENTS.md, README.md) — M fully populated, K skeleton Policies: N (X BLOCK, Y WARN) Rounds: N

The convention surface is ready. The feature-planning skill will read AGENTS.md and policies.md in its pre-flight; each policy's BLOCK / WARN severity drives the plan-review step.

Then ask:

> The convention docs have been written. Would you like to adjust anything, or is this ready to commit?

## Guidelines

- **Never invent answers.** If user intent is unclear, ask — do not assume project details.
- **Preserve specificity.** Generic content helps no one. Every sentence should be true of *this* project and false of
  some other project of the same stack.
- **One source of truth.** Policy rules live in `policies.md`; `AGENTS.md` summarizes via the marked block; never
  introduce a rule in `AGENTS.md` that does not exist in `policies.md`.
- **Refine respects user work.** In refine mode, treat existing content as authoritative unless the user signals
  otherwise.
- **Skeletons are real deliverables.** A skeleton with correct headers, working cross-links, and an empty bullet list is
  better than a fully-written doc that drifts from reality. Human authoring fills the rest.
- **Stack-specific examples.** Every code snippet in policies and standards uses the detected stack's primary language.
  Do not mix.
- **Edits over rewrites.** When updating files after a review round, use `Edit` against the specific section. Reserve
  `Write` for new files and for refresh of the auto-policy-summary block.
