Update Docs From Commits

Update Docs from Commits

Scan recent git history for commits that affect user-facing behavior and draft documentation updates for each.

Prerequisites

• You must be in the OpenShell git repository.
• The published docs tree must exist under docs/.
• Read docs/CONTRIBUTING.mdx before writing any content. It contains the current style guide and formatting rules.

When to Use

• After a batch of features or fixes has landed and docs may be stale.
• Before a release, to catch any doc gaps.
• When a contributor asks "what docs need updating?"

Step 1: Identify Relevant Commits

Determine the commit range. The user may provide one explicitly (e.g., "since v0.2.0" or "last 30 commits"). If not, default to commits since the head of the main branch.

# Commits since a tag
git log v0.2.0..HEAD --oneline --no-merges

# Or last 50 commits
git log -50 --oneline --no-merges

Filter to commits that are likely to affect docs. Look for these signals:

• Commit type: feat, fix, refactor, perf commits often change behavior. docs commits are already doc changes. chore, ci, test commits rarely need doc updates.
• Files changed: Changes to crates/openshell-cli/, python/, proto/, deploy/, gateway config parsing, driver config structs, or policy-related code are high-signal.
• Ignore: Changes limited to tests/, e2e/, .github/, tasks/, or internal-only modules.

# Show files changed per commit to assess impact
git log v0.2.0..HEAD --oneline --no-merges --name-only

Step 2: Map Commits to Doc Pages

For each relevant commit, determine which doc page(s) it affects. Use this mapping as a starting point:

| Code area | Likely doc page(s) |

|---|---|

| crates/openshell-cli/ (gateway commands) | docs/sandboxes/manage-gateways.mdx |

| crates/openshell-cli/ (sandbox commands) | docs/sandboxes/manage-sandboxes.mdx |

| crates/openshell-cli/ (provider commands) | docs/sandboxes/manage-providers.mdx |

| crates/openshell-cli/ (new top-level command) | May need a new page or docs/reference/ entry |

| crates/openshell-server/src/config_file.rs or gateway TOML parsing | docs/reference/gateway-config.mdx |

| crates/openshell-server/src/cli.rs gateway config merge/default behavior | docs/reference/gateway-config.mdx |

| crates/openshell-driver-*/ config structs or driver defaults | docs/reference/gateway-config.mdx, docs/reference/sandbox-compute-drivers.mdx |

| deploy/helm/openshell/templates/gateway-config.yaml | docs/reference/gateway-config.mdx, docs/reference/sandbox-compute-drivers.mdx, Helm docs if values change |

| Proxy or policy code | docs/sandboxes/policies.mdx, docs/reference/policy-schema.mdx |

| Inference code | docs/inference/configure.mdx |

| python/ (SDK changes) | docs/reference/ or docs/get-started/quickstart.mdx |

| proto/ (API changes) | docs/reference/ |

| deploy/ (Dockerfile, Helm) | docs/sandboxes/manage-gateways.mdx, docs/about/architecture.mdx |

| Community sandbox definitions | docs/sandboxes/community-sandboxes.mdx |

If a commit does not map to any existing page but introduces a user-visible concept, flag it as needing a new page.

Step 3: Read the Commit Details

For each commit that needs a doc update, read the full diff to understand the change:

git show <commit-hash> --stat
git show <commit-hash>

Extract:

• What changed (new flag, renamed command, changed default, new feature).
• Why it changed (from the commit message body, linked issue, or PR description).
• Any breaking changes or migration steps.

Step 4: Read the Current Doc Page

Before editing, read the full target doc page to understand its current content and structure:

# Read the file

Identify where the new content should go. Follow the page's existing structure.

Step 5: Draft the Update

Write the doc update following the rules in docs/CONTRIBUTING.mdx. Key reminders:

• Active voice, present tense, second person.
• No unnecessary bold. Reserve bold for UI labels and parameter names.
• No em dashes unless used sparingly. Prefer commas or separate sentences.
• Start sections with an introductory sentence that orients the reader.
• No superlatives. Say what the feature does, not how great it is.
• Code examples use shell language for copyable commands, with no $ prompt prefix.
• Use text fences for transcripts, logs, or shell sessions that should not be copied verbatim.
• Include the SPDX header as YAML comments in frontmatter if creating a new page.
• Match existing Fern frontmatter format if creating a new page, including sidebar-title, keywords, and position when they are relevant. Use frontmatter slug only for folder-discovered pages or absolute URL overrides.
• Use sidebar-title for short nav labels. For explicit navigation entries, keep relative slug values in docs/index.yml instead of page frontmatter.
• Keep explicit page: entries in docs/index.yml. Fern still requires them. If the page defines sidebar-title, set page: to that value. Otherwise set page: to the page frontmatter title.
• Use skip-slug: true in docs/index.yml when a child page should live at the parent section path.
• Use keywords as a comma-separated string.
• Do not add a duplicate H1. Fern renders the page title from frontmatter.
• Always write NVIDIA in all caps. Wrong: Nvidia, nvidia.
• Always capitalize OpenShell correctly. Wrong: openshell, Openshell, openShell.
• Do not number section titles. Wrong: "Section 1: Deploy a Gateway" or "Step 3: Verify." Use plain descriptive titles.
• No colons in titles. Wrong: "Gateways: Deploy and Manage." Write "Deploy and Manage Gateways" instead.
• Use colons only to introduce a list. Do not use colons as general-purpose punctuation between clauses.

When updating an existing page:

• Add content in the logical place within the existing structure.
• Do not reorganize sections unless the change requires it.
• Update any cross-references or "Next Steps" links if relevant.

When creating a new page:

• Follow the frontmatter template from docs/CONTRIBUTING.mdx.
• Add the page to the appropriate section in docs/index.yml.

Step 6: Present the Results

After drafting all updates, present a summary to the user:

## Doc Updates from Commits

### Updated pages
- `docs/sandboxes/manage-gateways.mdx`: Added `--gpu` flag documentation (from commit abc1234).
- `docs/reference/policy-schema.mdx`: Updated network policy schema for new `tls_inspect` field (from commit def5678).

### New pages needed
- None (or list any new pages created).

### Commits with no doc impact
- `chore(deps): bump tokio` (abc1234) — internal dependency, no user-facing change.
- `test(e2e): add gateway timeout test` (def5678) — test-only change.

Step 7: Build and Verify

After making changes, validate the Fern docs locally:

mise run docs

If a human needs to inspect rendering while iterating, they can also run:

mise run docs:serve

Check for:

• Validation warnings or errors.
• Broken cross-references.
• Correct rendering of new content in the PR preview when available.

Tips

• When in doubt about whether a commit needs a doc update, check if the commit message references a CLI flag, config option, or user-visible behavior.
• Group related commits that touch the same doc page into a single update rather than making multiple small edits.
• If a commit is a breaking change, add a note at the top of the relevant section using a Fern <Warning> callout.
• PRs that are purely internal refactors with no behavior change do not need doc updates, even if they touch high-signal directories.

Example Usage

User says: "Catch up the docs for everything merged since v0.2.0."

• Run git log v0.2.0..HEAD --oneline --no-merges --name-only.
• Filter to feat, fix, refactor, perf commits touching user-facing code.
• Map each to a doc page.
• Read the commit diffs and current doc pages.
• Draft updates following the style guide.
• Present the summary.
• Run mise run docs to verify.
