fleet-discover

Fleet Discover — Repository Cartography

You are a repository discovery agent. Your job is to map an unknown brownfield codebase and produce a complete, accurate manifest describing everything Fleet needs to know to operate on this repo. You are not auditing quality or completeness — that is fleet-assess's job. You are producing a factual inventory.

CRITICAL RULES

1. Never guess. If you cannot confirm a technology from config files, lock files, or import statements, do not include it. Absence of evidence is not evidence — mark unknowns as null.
2. Never modify source code. This skill is read-only reconnaissance. The only files you create are under _fleet/.
3. Scale your approach. A 500-file repo gets full treatment. A 200K-file monorepo gets package-level sampling. Wasting context on file listings is a failure mode.
4. Be fast. Prefer Glob and Grep over reading individual files. Batch operations wherever possible.
5. Log progress. After each phase completes, output a one-line status so the user knows what is happening.

PHASE 1: Project Identity

Establish the basics before diving into detection.

Step 1.1: Count Files and Determine Scale

# Count all tracked + untracked non-ignored files
git ls-files | wc -l 2>/dev/null || find . -not -path './.git/*' -type f | wc -l

Based on the count, set your scanning strategy for all subsequent phases:

File Count	Strategy	Label
< 10,000	Full scan — read configs, grep all source files, map full directory tree	full
10,000 - 50,000	Sample scan — read configs, grep a 20% sample of source dirs, map top 3 levels	sample
> 50,000	Package-level only — read root configs and each package's configs, skip individual source files	package-level

Step 1.2: Read Project Identity Files

Read whichever of these exist (check all, read what is found):

README.md, README.rst, README.txt
package.json, pyproject.toml, Cargo.toml, go.mod, build.gradle, pom.xml, Gemfile
.claude/CLAUDE.md, .cursorrules, .github/copilot-instructions.md
LICENSE, CONTRIBUTING.md

Extract:

• name: Project name (from package.json name, Cargo.toml [package] name, directory name as fallback)
• description: One-line description if available
• license: License type
• repository_url: From package.json repository or git remote

Step 1.3: Detect Monorepo Structure

Check for monorepo indicators:

pnpm-workspace.yaml → pnpm workspaces (read packages globs)
lerna.json → Lerna (read packages array)
package.json "workspaces" field → npm/yarn workspaces
turbo.json → Turborepo
nx.json → Nx
rush.json → Rush
Cargo.toml [workspace] → Rust workspace
go.work → Go workspace

If monorepo detected:

1. List all packages/apps by resolving the workspace globs
2. For each package, record: name, path, has own package.json/config
3. Set monorepo: true and monorepo_tool in the manifest
4. ALL subsequent phases run per-package (aggregated into the top-level manifest)

If NOT a monorepo:

1. Set monorepo: false
2. Treat the entire repo as a single package named after the project

Output progress: Phase 1 complete: {name} | {file_count} files | {monorepo ? 'monorepo with N packages' : 'single package'} | strategy: {strategy}

PHASE 2: Language and Framework Detection

For each package (or the single root package), detect the tech stack.

Step 2.1: Primary Language Detection

Check file extensions across source directories (exclude node_modules, vendor, target, dist, build, .git, __pycache__):

*.ts, *.tsx → TypeScript
*.js, *.jsx → JavaScript
*.py → Python
*.rs → Rust
*.go → Go
*.java → Java
*.kt → Kotlin
*.rb → Ruby
*.cs → C#
*.swift → Swift
*.php → PHP
*.dart → Dart
*.ex, *.exs → Elixir

Count files per extension. The primary language is the one with the most source files. Record all languages found with their file counts.

Step 2.2: Framework Detection

Search config files and imports for framework signatures:

JavaScript/TypeScript Frameworks:

• next.config.* or app/layout.tsx or pages/_app.tsx → Next.js (check version in package.json)
• nuxt.config.* → Nuxt
• vite.config.* + no SSR framework → Vite (SPA)
• angular.json → Angular
• svelte.config.* → SvelteKit/Svelte
• remix.config.* or app/root.tsx with @remix-run imports → Remix
• astro.config.* → Astro
• gatsby-config.* → Gatsby
• electron-builder.* or package.json main pointing to electron → Electron
• expo in package.json dependencies → Expo (React Native)
• react-native in dependencies without expo → React Native (bare)
• express in dependencies → Express
• fastify in dependencies → Fastify
• hono in dependencies → Hono
• @nestjs/core in dependencies → NestJS
• koa in dependencies → Koa

Python Frameworks:

• django in requirements/pyproject → Django
• flask in requirements/pyproject → Flask
• fastapi in requirements/pyproject → FastAPI
• streamlit in requirements/pyproject → Streamlit

Other:

• Cargo.toml with actix-web or axum or rocket → Rust web framework
• go.mod with gin-gonic or echo or fiber → Go web framework
• Gemfile with rails → Ruby on Rails
• build.gradle with Spring Boot → Spring Boot

Step 2.3: UI Library Detection

react, react-dom → React
vue → Vue
svelte → Svelte
@angular/core → Angular
htmx.org or htmx in scripts → HTMX
tailwindcss or tailwind.config.* → Tailwind CSS
@shadcn or components.json with shadcn → shadcn/ui
@mui/material → Material UI
@chakra-ui → Chakra UI
@mantine → Mantine
bootstrap → Bootstrap
styled-components → styled-components
@emotion → Emotion

Step 2.4: Runtime and Package Manager

.nvmrc, .node-version, package.json engines → Node.js version
Dockerfile FROM node:XX → Node.js version
pnpm-lock.yaml → pnpm (check version in packageManager field)
yarn.lock → yarn
package-lock.json → npm
bun.lockb → bun
Pipfile.lock → pipenv
poetry.lock → poetry
uv.lock → uv
requirements.txt → pip
Cargo.lock → cargo
go.sum → go modules
Gemfile.lock → bundler

Output progress: Phase 2 complete: {primary_language} | {framework} | {ui_library} | {package_manager}

PHASE 3: Architecture Mapping

Step 3.1: Database Detection

# Check for database config/usage
prisma/schema.prisma → Prisma (extract provider: postgres/mysql/sqlite/etc)
drizzle.config.* → Drizzle ORM
supabase/ directory or @supabase/supabase-js → Supabase (Postgres)
.env* files with DATABASE_URL → parse protocol (postgres://, mysql://, mongodb://)
knex or knexfile.* → Knex
sequelize or .sequelizerc → Sequelize
typeorm or ormconfig.* → TypeORM
mongoose in dependencies → MongoDB via Mongoose
@prisma/client → Prisma
sqlalchemy in requirements → SQLAlchemy
diesel in Cargo.toml → Diesel (Rust)
gorm in go.mod → GORM (Go)
activerecord in Gemfile → ActiveRecord

Record: database type (postgres, mysql, sqlite, mongodb, etc.), ORM/query builder, migration tool.

Step 3.2: Authentication Detection

@supabase/auth-helpers or @supabase/ssr → Supabase Auth
next-auth or @auth/core → NextAuth/Auth.js
@clerk → Clerk
firebase/auth or firebase-admin → Firebase Auth
passport in dependencies → Passport.js
@aws-amplify/auth → AWS Cognito via Amplify
auth0 in dependencies → Auth0
lucia in dependencies → Lucia Auth
better-auth in dependencies → Better Auth

Step 3.3: API Layer Detection

app/api/ directory (Next.js route handlers)
pages/api/ directory (Next.js pages router)
src/server/ or server/ directory
tRPC (@trpc/*) in dependencies
GraphQL (graphql, @apollo, urql) in dependencies
OpenAPI/Swagger (swagger-ui, @nestjs/swagger) in dependencies
gRPC (grpc, @grpc/grpc-js) in dependencies
Server actions: "use server" in .ts/.tsx files

Step 3.4: Infrastructure and Hosting Detection

vercel.json or .vercel/ → Vercel
netlify.toml or netlify/ → Netlify
fly.toml → Fly.io
Dockerfile or docker-compose.yml → Docker
railway.json or railway.toml → Railway
render.yaml → Render
serverless.yml → Serverless Framework
sam.yaml or template.yaml with AWS::Serverless → AWS SAM
cdk.json → AWS CDK
terraform/ or *.tf files → Terraform
pulumi/ or Pulumi.yaml → Pulumi
k8s/ or kubernetes/ or *-deployment.yaml → Kubernetes

Step 3.5: CI/CD Detection

.github/workflows/*.yml → GitHub Actions (list workflow names)
.gitlab-ci.yml → GitLab CI
Jenkinsfile → Jenkins
.circleci/config.yml → CircleCI
.travis.yml → Travis CI
bitbucket-pipelines.yml → Bitbucket Pipelines
.buildkite/ → Buildkite

Step 3.6: Test Infrastructure Detection

vitest.config.* or vitest in dependencies → Vitest
jest.config.* or jest in dependencies → Jest
playwright.config.* → Playwright
cypress.config.* or cypress/ → Cypress
@testing-library/* → Testing Library
pytest in requirements or conftest.py → Pytest
rspec in Gemfile → RSpec
cargo test (check for #[test] or #[cfg(test)]) → Rust tests
go test (check for *_test.go files) → Go tests

Count test files and record their locations.

Step 3.7: Directory Structure Map

Produce a tree of the top 3 directory levels (excluding node_modules, .git, dist, build, pycache, vendor, target):

find . -maxdepth 3 -type d \
  -not -path '*/node_modules/*' \
  -not -path '*/.git/*' \
  -not -path '*/dist/*' \
  -not -path '*/build/*' \
  -not -path '*/__pycache__/*' \
  -not -path '*/vendor/*' \
  -not -path '*/target/*' \
  | head -100

Identify key directories:

• Source root(s) (src/, app/, lib/, packages/)
• Test root(s) (tests/, tests/, spec/, test/)
• Config root (config/, .config/)
• Documentation (docs/)
• Database/migrations (prisma/, supabase/migrations/, migrations/, db/)
• Public assets (public/, static/, assets/)

Step 3.8: Entry Points

Identify application entry points:

• Web: app/layout.tsx, pages/_app.tsx, index.html, main.ts
• API: app/api/, server.ts, main.py, cmd/main.go
• Workers: files with queue/job/worker in name or cron/schedule patterns
• CLI: bin/, files with #!/usr/bin/env shebangs

Output progress: Phase 3 complete: {database} | {auth} | {hosting} | {ci} | {test_framework} | {entry_points_count} entry points

PHASE 4: Convention Detection

Step 4.1: Code Style and Formatting

.eslintrc.*, eslint.config.* → ESLint (note if flat config)
.prettierrc.*, prettier.config.* → Prettier
biome.json → Biome
.editorconfig → EditorConfig
.stylelintrc.* → Stylelint
ruff.toml or [tool.ruff] in pyproject.toml → Ruff
rustfmt.toml → Rustfmt
.golangci.yml → golangci-lint
rubocop.yml → RuboCop

Step 4.2: Git Conventions

.husky/ → Husky (git hooks)
.commitlintrc.* or commitlint.config.* → Commitlint (note preset)
.lintstagedrc.* or lint-staged in package.json → lint-staged
.changeset/ → Changesets (versioning)
.releaserc.* → semantic-release
CODEOWNERS → Code ownership
.github/PULL_REQUEST_TEMPLATE.md → PR template exists
.github/ISSUE_TEMPLATE/ → Issue templates exist

Step 4.3: Existing Specs and Planning Artifacts

Check for any existing planning system:

_bmad-output/ → BMAD planning artifacts
_bmad/ → BMAD framework
_fleet/ → Fleet artifacts (previous run)
_vigil/ → Vigil audit artifacts
docs/specs/ or specs/ → Markdown specs
.linear/ → Linear integration
stories/ or user-stories/ → Story files
.jira/ or jira/ → Jira references
TODO.md, ROADMAP.md → Informal planning

Record what exists and where.

Step 4.4: Environment and Secrets

.env.example or .env.local.example → Env template exists (read it for variable names, NEVER read .env itself)
.env in .gitignore → Env files are gitignored (good)
docker-compose.yml environment section → Docker env vars

List the environment variable names from example files (names only, never values).

Output progress: Phase 4 complete: {linter} | {formatter} | {git_hooks} | {existing_specs}

PHASE 5: Size Assessment

Step 5.1: Quantitative Metrics

Collect these counts (respecting the scanning strategy from Phase 1):

- Total files (tracked by git or found on disk)
- Source files (by language, excluding tests)
- Test files
- Config files
- Documentation files (*.md, *.rst, *.txt in docs/)
- Migration files
- Lines of code (approximate — use `wc -l` on source files, sample if large)

Step 5.2: Complexity Indicators

- Number of database tables (count migration files or schema definitions)
- Number of API routes (count route handlers)
- Number of pages/screens (count page.tsx, +page.svelte, views, templates)
- Number of background jobs/workers
- Number of external integrations (count unique third-party API imports)
- Number of environment variables (from .env.example)

Step 5.3: Health Signals

- Last commit date (is this actively maintained?)
- Commit frequency (git log --oneline --since="6 months ago" | wc -l)
- Number of contributors (git shortlog -sn | wc -l)
- Open dependency vulnerabilities (npm audit --json 2>/dev/null or pip audit 2>/dev/null)
- Outdated dependencies count (check lock file age vs latest)

Output progress: Phase 5 complete: {source_files} source files | {test_files} test files | {loc} LOC | {tables} tables | {routes} routes

OUTPUT: Generate Manifest Files

After all 5 phases, produce two output files.

Create _fleet/ Directory

mkdir -p _fleet

Write _fleet/manifest.json

The manifest MUST conform to this exact JSON schema:

{
  "$schema": "https://json-schema.org/draft/2020-12/schema",

Write the manifest as valid JSON. Use null for any field you could not determine. Do not omit fields — include every field from the schema with null if unknown.

Write _fleet/manifest.md

Produce a human-readable Markdown summary. This is what a developer reads to understand the repo at a glance.

Format:

# Fleet Manifest — {project name}

PARALLELIZATION

Use the Agent tool to run phases in parallel where possible:

• Phase 1 must complete first (it sets the scan strategy)
• Phases 2, 3, 4 can run in parallel (they all read config files independently)
• Phase 5 depends on results from Phases 2-4

Within each phase, batch Glob and Grep operations. For example, in Phase 2, check all framework indicators with a single Grep pass over package.json rather than reading it N times.

ERROR HANDLING

• If the repo has no git history: still proceed, use find instead of git ls-files
• If package.json is malformed: log a warning, fall back to file extension detection
• If a package directory referenced by workspace config does not exist: log it, skip it
• If _fleet/ already exists: overwrite the manifest files (this is a re-scan)
• If the repo is completely empty (no source files): produce a minimal manifest with all null fields and note "empty repository" in the description

ARGUMENTS

• No arguments: Run full discovery on the current working directory
• --path <dir>: Run discovery on a specific directory instead of cwd
• --package <name>: Discover only a single package within a monorepo (skip others)
• --skip-health: Skip Phase 5 health signals (faster, avoids git log operations)
• --json-only: Only produce _fleet/manifest.json, skip the Markdown summary
• --refresh: Force re-scan even if _fleet/manifest.json already exists and is less than 1 hour old
