sync-openapi-spec

name	sync-openapi-spec
description	Sync the public Oz Agent API OpenAPI spec from warp-server into the docs repo, regenerating `developers/agent-api-openapi.yaml` (the file that powers the Scalar API reference at `docs.warp.dev/api`). Use when the warp-server public API has changed, when the Scalar reference looks stale, or on a scheduled cadence to keep the public API docs aligned with the canonical spec.

Sync OpenAPI Spec

Keep developers/agent-api-openapi.yaml in sync with the canonical spec at warp-server/public_api/openapi.yaml.

Direction: warp-server → docs. The server spec is the source of truth. The docs file is a curated subset (drops memory_stores/harness-support and a handful of internal agent paths) that Scalar renders on docs.warp.dev/api.

Repos

This skill requires two repos in the agent's environment:

• warpdotdev/warp-server — source of truth (public_api/openapi.yaml)
• warpdotdev/docs — Scalar-facing copy (developers/agent-api-openapi.yaml)

Prerequisites

• Both repos checked out, with warp-server reachable from the docs repo (default assumption: sibling directories — ../warp-server/public_api/openapi.yaml)
• Python 3 with pyyaml installed (pip install pyyaml or pip install --break-system-packages pyyaml in managed environments)
• gh CLI authenticated against warpdotdev/docs

Workflow

Step 1: Self-test

Run the script's self-test first to confirm pyyaml is available and the transform logic still passes:

python3 .agents/skills/sync-openapi-spec/scripts/sync_openapi.py --mode self-test

Expected output: self-test: OK. If this fails, fix the script before going further.

Step 2: Diff source against target

python3 .agents/skills/sync-openapi-spec/scripts/sync_openapi.py \
  --mode diff \
  --source ../warp-server/public_api/openapi.yaml \
  --target developers/agent-api-openapi.yaml

The script prints structural drift grouped into:

• Paths added/removed/modified relative to the expected docs subset
• Component schemas added/removed/modified
• Top-level changes (openapi, info, servers)
• Unclassified tags or paths (anything not covered by EXCLUDED_TAGS or the agent/schedules allowlist)

If the script reports In sync. No changes needed., stop here.

Step 3: Triage unclassified items

Any line prefixed with ! flags a tag or path the policy doesn't recognize. Do NOT auto-include or auto-drop these. For each one:

1. Read the corresponding handler in warp-server/router/handlers/public_api/ to confirm whether the endpoint is intended to be public.
2. If the endpoint is public-facing, leave the policy alone — the script will include it on the next apply.
3. If the endpoint should remain hidden, extend EXCLUDED_TAGS or EXCLUDED_PATHS in scripts/sync_openapi.py and update references/sync-policy.md to record the rationale.
4. Re-run --mode diff until no ! lines remain.

Step 4: Apply the regenerated subset

python3 .agents/skills/sync-openapi-spec/scripts/sync_openapi.py \
  --mode apply \
  --source ../warp-server/public_api/openapi.yaml \
  --target developers/agent-api-openapi.yaml

This rewrites developers/agent-api-openapi.yaml with the regenerated subset. Apply mode validates every $ref in the output before writing the file: if any reference is unresolved, the script exits with code 3 and refuses to write. On success it prints All $refs resolve in the regenerated spec.

Step 5: Validate the regenerated spec

Apply mode already catches unresolved $refs (see Step 4). Run these as belt-and-braces integration checks:

# Astro picks up the new YAML and parses it through Scalar's runtime.
npm run build

Optional, recommended when many schemas changed (full OpenAPI lint):

npx @redocly/cli lint developers/agent-api-openapi.yaml

If npm run build fails, the most common cause is a malformed path or missing description field. Schema-ref breakage is already prevented by Step 4's validator.

Step 6: Commit and open a PR

git checkout -b sync-openapi-spec/YYYY-MM-DD
git add developers/agent-api-openapi.yaml
git commit -m "docs: sync agent-api-openapi.yaml from warp-server

Co-Authored-By: Oz <[e-mail]>"
git push origin sync-openapi-spec/YYYY-MM-DD

Open a draft PR. Write the body to a file before creating the PR — the diff output from Step 2 can be long and is prone to repetition-loop degeneration when passed inline:

cat > /tmp/sync-openapi-pr-body.md << 'EOF'
[Paste the full output from Step 2 here: paths/schemas added/removed/modified]

Co-Authored-By: Oz <[e-mail]>
EOF

python3 .agents/skills/create_pr/check_pr_body.py /tmp/sync-openapi-pr-body.md
gh pr create --draft \
  --title "docs: sync agent-api-openapi.yaml from warp-server" \
  --label documentation \
  --body-file /tmp/sync-openapi-pr-body.md

Use report_pr to surface the PR link.

Step 7: Report

Summarize:

• Source commit SHA used (capture with cd ../warp-server && git rev-parse HEAD)
• Number of paths added / removed / modified in the regenerated subset
• Number of schemas added / removed / modified
• Any items flagged for triage and how they were resolved
• Or confirm In sync. No changes needed.

Sync policy

The policy is encoded in scripts/sync_openapi.py as EXCLUDED_TAGS and EXCLUDED_PATHS. See references/sync-policy.md for the rationale behind each entry and the rules for adding new ones.

Schedule

Run on demand whenever warp-server/public_api/openapi.yaml has changed materially since the last docs sync, or on a weekly cadence as a safety net.

Troubleshooting

ModuleNotFoundError: No module named 'yaml'

Install pyyaml: pip install pyyaml. On Debian-based images with externally managed Python, use pip install --break-system-packages pyyaml.

error: source spec not found at ...

The warp-server repo isn't where the script expected. Pass --source /absolute/path/to/warp-server/public_api/openapi.yaml.

--mode apply exits with code 3 and "unresolved $refs"

Apply mode refuses to write the target if any $ref in the regenerated spec doesn't resolve to a defined component. The script's recursive $ref walker is supposed to keep transitive references (allOf/oneOf/anyOf/items/additionalProperties/etc.) reachable, so this means either:

• The source spec itself has a dangling reference (fix it in warp-server), or
• The walker is missing a reference shape (file a bug against the script).

The error output lists the offending JSON pointer paths so you can locate the reference quickly. Apply will not overwrite developers/agent-api-openapi.yaml while this fails.

Diff shows changes that aren't in the source spec

Make sure ../warp-server is on the branch you intended to compare against (usually develop). Run cd ../warp-server && git status -sb && git --no-pager log -1 to confirm.
