logos-project.yaml

logos-project.yaml is the AI collaboration index file for OpenLogos projects. It provides AI assistants with global project context — which key files to read, what tech stack is used, and what conventions to follow.

logos/logos-project.yaml
project: # Project basics (required)
tech_stack: # Technology stack (required)
scenario_counter: # Global scenario ID counter (required for multi-module)
modules: # Module registry (required for multi-module)
scenarios: # Scenario list (optional, written before Phase 3-1)
external_dependencies: # External service dependencies (optional)
resource_index: # Resource file index (required)
conventions: # Project conventions (optional)
FieldTypeRequiredDescription
namestringYesProject name
descriptionstringYesOne-line project description
methodologystringNoMethodology followed (default: "OpenLogos")

Free-form key-value pairs describing the project’s technology stack. Recommended keys:

KeyDescriptionExample
frameworkPrimary framework"Next.js 15"
languagePrimary language"TypeScript"
hostingDeployment platform"Cloudflare Pages"
databaseDatabase"Supabase (PostgreSQL)"
authAuthentication solution"Supabase Auth"

Array of external service dependencies with their testing strategies. Defined during the architecture design phase (Step 0), consumed by the test orchestration phase (Step 3b).

FieldTypeRequiredDescription
namestringYesDependency name (e.g., “Email Service”, “CAPTCHA”)
providerstringYesSpecific provider (e.g., “SendGrid”, “reCAPTCHA”)
used_inarrayYesScenarios using this dependency (e.g., ["S01-User Registration"])
test_strategystringYesTesting strategy enum (see table below)
test_configstringYesTesting strategy configuration details
ValueDescriptionTypical Use Case
test-apiTest environment provides backdoor API for verification codes/callbacksEmail/SMS verification codes
fixed-valueSpecific test data uses fixed valuesTest phone numbers with fixed verification codes
env-disableFeature disabled via environment variableCAPTCHAs, slider verification
mock-callbackOrchestration actively calls mock callback endpointsPayment callbacks, Webhooks
mock-serviceLocal mock service replaces the real oneOAuth providers, third-party APIs

Array of key resource files that AI should know about:

FieldTypeRequiredDescription
pathstringYesFile path relative to project root
descstringYesOne-line description — tells AI when to read this file

Object that maintains a globally unique scenario ID counter. Required for multi-module projects to ensure scenario IDs never collide across modules.

FieldTypeRequiredDescription
next_idintegerYesThe next scenario number to use (e.g., 8 means the next scenario is S08)

AI must read this field before generating a new scenario, increment it immediately after, and write it back. Never restart numbering from S01 in a new module.

Array of registered modules. Required for multi-module projects. openlogos init automatically writes the initial core module entry.

FieldTypeRequiredDescription
idstringYesModule identifier — lowercase letters, digits, hyphens (e.g., core, admin)
namestringYesHuman-readable module name
lifecyclestringYesinitial (phase-driven development) or launched (change-proposal-driven)
bootstrapstringNoOnboarding mode: normal (default, full Phase 1→3) or adopted (existing project, initial doc baseline skipped). Written by openlogos adopt. Historical value skipped is read-compatible with adopted.
skip_phasesarrayNoPhases this module doesn’t need. Written by architecture-designer Skill after tech stack selection.
deployment_requiredbooleanNoWhether this module requires deployment execution gates. Software projects default to true; pure docs or libraries can set false.

bootstrap field semantics:

ValueMeaningWritten by
normal (or absent)Full Phase 1→3 document baseline before iterationopenlogos init (default)
adoptedExisting project onboarding; OpenLogos infra fully initialized but initial doc baseline skippedopenlogos adopt
skippedHistorical compatibility value, read-equivalent to adopted, no longer writtenOld openlogos adopt versions

When bootstrap: adopted:

  • status: Phase 1, 2, 3-0 missing docs don’t report as errors — shows “Document baseline skipped (existing project onboarding)”
  • next: When no active proposal, suggests openlogos change add-baseline-docs
  • launch: Exempted from initial document gate checks
  • detect/status --format json: Outputs bootstrap: "adopted"

skip_phases allowed values:

ValueSkipsWhen to use
apilogos/resources/api/No HTTP API (desktop app, CLI tool, frontend library)
databaselogos/resources/database/No database (stateless CLI, pure compute)
scenariologos/resources/scenario/No API orchestration tests (usually paired with api)
deploymentDeployment execution + smoke gatesPure docs, no runtime environment needed

Array declaring the project’s complete scenario list. Scenarios are the central organizing unit of the OpenLogos methodology — all phase deliverables are keyed to scenario IDs.

When to write: After architecture-designer Skill completes, before scenario-architect Skill begins.

FieldTypeRequiredDescription
idstringYesGlobally unique scenario ID, format S + two digits (e.g., S01, S08)
namestringYesOne-line scenario description
modulestringNoOwning module ID. Defaults to core when omitted. Required for multi-module projects so openlogos status can compute per-module phase progress correctly.

openlogos sync automatically backfills missing module fields by scanning logos/resources/prd/3-technical-plan/2-scenario-implementation/ for <moduleId>-SXX-*.md files. Falls back to core when no match is found.

Array of project conventions (string format). Each element is one convention rule.

Declares deployment and smoke gate requirements for the initial phase (before openlogos launch). Written by the deployment-designer Skill, consumed by status / launch.

deployment_gates:
core:
deployment_required: true
smoke_required: true
environments:
- staging
FieldTypeRequiredDescription
<module_id>objectYesGate configuration per module
deployment_requiredbooleanYesWhether deployment execution is required before launch
smoke_requiredbooleanYesWhether smoke verification is required after deployment
environmentsarrayNoTarget deployment environments

If deployment_gates is not declared, software modules default to requiring a deployment plan; deployment execution and smoke gates are determined by the module’s deployment_required field and deployment plan content.

logos-project.yaml is the structured resource index; AGENTS.md is the natural language instruction file. They complement each other:

  • AGENTS.md directs AI: “Read logos/logos-project.yaml first”
  • logos-project.yaml tells AI: “These are the key files; here’s when to read each one”
  • openlogos sync updates AGENTS.md based on logos-project.yaml content

See AGENTS.md Specification for the instruction file format.
