# Go Project Documentation Policy
# Documentation Policy
## Purpose
Project documentation must help four audiences:
1. users who need to run the application;
2. administrators/operators who need to configure and operate it;
3. developers who need to understand and change it safely;
4. LLM coding agents that need clear scope, boundaries, and invariants.
Docs should be accurate, concise, task-oriented, and organized by audience. Prefer links to canonical docs over repetition.
This policy assigns each documentation topic to one canonical owner. Its goal is
to keep Narratio documentation accurate, concise, discoverable, and resistant
to drift for users, operators, developers, integrators, and LLM coding agents.
## Core Rules
### 1. Keep docs concise
### One Canonical Owner
Each authoritative fact belongs in one document. A non-owning document may give
a short, stable summary for orientation, but it must link to the canonical owner
instead of repeating volatile details.
Volatile details include commands, flags, configuration fields and defaults,
stage or integration keys, schemas, file names, paths, status codes, retry
behavior, and runtime guarantees. If readers could reasonably treat a statement
as a contract, maintain it only in the owning document.
Each document should cover a defined scope and only the essentials for that scope.
### Current And Future Behavior
Outside `docs/roadmap/`, documentation describes implemented behavior only.
Partial features may be described only to their implemented boundary.
ADRs are the narrow exception: an ADR may record an accepted architectural
decision before implementation, but acceptance must not be presented as proof
that the behavior exists. The roadmap owns implementation status and sequencing
until the decision is implemented. Current architecture, user, operator,
integration, and internal documentation are updated when the behavior lands.
### Audience And Detail
Write for the document's stated audience and include only the detail needed for
its owned topic. User and operator docs should not expose implementation detail.
Developer docs should link to user-facing and external contracts rather than
restate them.
### Examples
Avoid:
- long background explanations;
- repeated reference material;
- implementation detail in user-facing docs;
- aspirational language outside roadmap docs;
- verbose examples where one minimal example is clearer.
### 2. Document only implemented behavior outside roadmap files
Unimplemented, planned, aspirational, experimental, or future work may be described only under:
- `docs/roadmap/`
No other documentation file, including `README.md`, should describe code, features, modules, stages, commands, config fields, or behaviors that do not currently exist.
If a feature is partial, non-roadmap docs may describe only the implemented portion and its current boundary.
### 3. Use canonical homes
Each type of information should have one canonical location.
Canonical homes:
- project purpose and quickstart: `README.md`
- development principles: `docs/architecture.md`
- configuration reference: `docs/config.md`
- CLI reference: `docs/cli.md`
- operations and recovery: `docs/operations.md`
- troubleshooting: `docs/troubleshooting.md`
- implemented internals: `docs/internal/`
- future work: `docs/roadmap/`
- contributor workflow: `docs/development.md`
- copyable examples: `examples/`
Other files should summarize briefly and link to the canonical source.
### 4. Keep examples real
Examples should be valid, maintained, and free of secrets.
Where practical:
- example configs should load successfully;
- example commands should match real CLI syntax;
- important examples should be covered by tests.
## Documentation Profiles

## Required Documents
### README.md
**Audience:** users, administrators, operators
The README is the outward-facing project orientation page.
It should include, in order:
1. concise description;
2. elevator pitch;
3. shortest useful command or usage example;
4. links to targeted docs.
The README should be short. It is not a manual.
The “shortest useful command” means the simplest command that performs the projects core use case. (It does not mean `app --help`.)
### docs/architecture.md
**Audience:** developers, LLM coding agents
`docs/architecture.md` is required for every project.
It is an inward-facing development policy document. It should describe how the project is intended to be built and changed.
It should include:
- project shape;
- core design principles;
- package and boundary philosophy;
- state/persistence philosophy, if applicable;
- external integration philosophy, if applicable;
- error-handling and logging principles;
- testing expectations;
- documentation expectations;
- architectural invariants;
- explicit non-goals, if useful.
For small projects, this file may be brief. It may simply state that the project is intentionally narrow, monolithic, and dependency-light.
### docs/config.md
**Audience:** administrators, operators, advanced users
Required for applications with configuration files.
It should include, in order:
1. config file locations and discovery precedence;
2. minimal working config;
3. production-oriented config;
4. full configuration reference;
5. secrets handling, if applicable;
6. links to maintained examples.
The full configuration reference should be canonical.
### docs/cli.md
**Audience:** users, administrators, operators
Required for CLI applications.
It should include, in order:
1. shortest useful command;
2. command overview;
3. complete flag reference;
4. common workflows;
5. diagnostic or recovery commands, if applicable.
Explain when commands are useful, not just their syntax.
### docs/operations.md
**Audience:** administrators, operators
Required for applications that maintain state, support resume behavior, run multiple stages, write durable artifacts, use remote storage, or require recovery procedures.
It should cover:
- normal workflow;
- filesystem layout;
- remote storage layout, if applicable;
- logs and manifests;
- resume/retry behavior;
- cleanup behavior;
- archive/backup behavior;
- safe recovery procedures;
- operational caveats.
### docs/troubleshooting.md
**Audience:** administrators, operators
Recommended once recurring failure modes exist.
Each entry should include:
- symptom;
- likely cause;
- diagnostic command or inspection step;
- safe fix;
- relevant links.
### docs/development.md
**Audience:** developers, LLM coding agents
Required for projects maintained by humans and LLM coding agents.
It should include:
- repository layout;
- build/test commands;
- coding conventions;
- dependency policy;
- how to add config fields;
- how to add CLI flags;
- how to add stages/modules/adapters, if applicable;
- how to update examples;
- documentation update expectations.
### docs/internal/
**Audience:** developers, LLM coding agents
Required for modular, staged, service-oriented, or orchestration projects.
This directory describes implemented internal components. It is not the roadmap.
Use one file per major component where useful.
Each component doc should include:
1. purpose;
2. inputs and outputs;
3. boundaries;
4. config fields used;
5. external adapters used;
6. state or manifest behavior, if applicable;
7. skip/resume behavior, if applicable;
8. failure behavior;
9. tests to inspect before changing;
10. architectural invariants.
### docs/roadmap/
**Audience:** maintainers, developers, LLM coding agents
This is the only place for planned, future, aspirational, experimental, or unimplemented work.
Roadmap docs should clearly distinguish:
- proposed work;
- accepted plans;
- deferred ideas;
- rejected ideas;
- implementation prompts or task breakdowns, if useful.
Roadmap docs should not be confused with current behavior.
### docs/integrations/
**Audience:** developers, LLM coding agents
Required for projects that depend on external CLIs, APIs, services, protocols, or file formats where the integration contract is important to maintain.
This directory contains concise, versioned reference notes for external integration contracts. It should document only the parts of the external system that this project actually uses.
Use one file per integration where useful.
## Examples Directory
Projects with non-trivial configuration or workflows should include `examples/`.
Useful examples include:
- minimal working config;
- production-oriented config;
- full annotated config;
- local development config;
- remote/object-storage config;
- minimal session/input file.
Examples should be valid, maintained, tested when practical, and linked from relevant docs.
## Security and Privacy
Docs and examples must not include:
- real API keys;
- tokens;
- passwords;
- private keys;
- private environment dumps;
- sensitive user data;
- raw private transcripts;
- private infrastructure details unless intentionally public.
Document secret-handling mechanisms, not actual secret values.
## Maintenance Rules
When docs change, verify the affected behavior.
Where practical:
- load example config files in tests;
- test CLI examples or command parser behavior;
- validate documented flags against real flags;
- remove stale references;
- update links after renames;
- keep roadmap content out of non-roadmap docs.
If documentation and code disagree, fix the documentation and/or open a roadmap item; do not leave aspirational behavior in current-behavior docs.
Documentation is complete only when it matches the current code.
## Documentation Change Checklist
Before merging documentation changes, verify:
- README is concise and orientation-focused.
- `docs/architecture.md` describes development principles.
- Future work appears only under `docs/roadmap/`.
- User-facing docs avoid unnecessary internals.
- Developer-facing docs preserve boundaries and invariants.
- Config examples match the schema.
- CLI examples match real commands and flags.
- Defaults appear in the canonical config reference.
- No secrets or private data are included.
- Links are accurate.
Complete copyable files belong in `examples/`. Documentation may use the
smallest illustrative snippet needed to explain its owned topic, but should link
to maintained examples instead of embedding a second complete copy.
Examples must be valid, secret-free, and tested where practical. Commands and
configuration used in documentation should match the application.
### Security And Privacy
Documentation and examples must not contain real credentials, private keys,
private environment dumps, sensitive source material, or private infrastructure
details unless intentionally public. Document secret-handling mechanisms, not
secret values.

or operations documents for behavior the application does not have.
## Boundary Rules
### Orientation
The README owns product orientation. The developer guide routes contributors.
Architecture owns normative structure. Internal overview owns the current
concrete component map. These documents may link to one another but should not
maintain parallel package or behavior descriptions.
### Commands, Configuration, Operations, And Troubleshooting
CLI documentation answers how to invoke the application. Configuration
documentation answers what settings mean. Operations answers what happens to
runtime state and how to operate or recover the application. Troubleshooting
starts from observable symptoms and links readers to the owning command,
configuration, operational, or integration contract. When a workflow crosses
these topics, choose the document that owns the task and link to the other
contracts.
### Contracts And Implementation
Integration and API documents define externally observable shapes and
semantics. Internal documents explain how Narratio implements or consumes those
contracts. Internal docs may name a field, file, or protocol to identify a
dependency, but must link to its canonical contract for the definition.
### Security Topics
This policy owns what documentation and examples may contain. Architecture owns
application security invariants. Configuration owns credential-supply
mechanisms. Operations owns permissions and handling of sensitive runtime
artifacts. Troubleshooting owns safe diagnostic and remediation guidance.
Internal docs own implementation mechanisms only.
## Architecture Decision Records
Use sequentially numbered ADR filenames such as
`0001-record-architecture-decisions.md`. Follow the lightweight Nygard format:
1. title;
2. status;
3. date;
4. context;
5. decision;
6. alternatives considered;
7. consequences.
Treat the decision content of an accepted ADR as immutable. When a decision
changes, create a new ADR and update the earlier ADR's status to superseded.
Rejected architectural alternatives belong in the ADR; rejected product ideas
belong in the roadmap.
## Maintenance
When behavior changes, update its canonical owner in the same change. If
ownership moves, remove the old definition and replace it with a link where
navigation remains useful.
Before completing documentation work:
- verify affected behavior and examples;
- check commands, flags, fields, defaults, schemas, and paths against their
implementation;
- keep unimplemented behavior in the roadmap, subject to the ADR exception;
- remove stale references and validate links;
- confirm that non-owning documents summarize and link rather than redefine;
- confirm that no secrets or sensitive private data were added.
