Northjetty Publish Traces

NorthJetty trace publishing

Create a portable static trace viewer without bundling trace data. Treat traces as runtime inputs and keep every generated site outside this skill directory.

Non-negotiable rules

• Never copy a trace, generated chunk, manifest containing trace entries, API key, or route access code into this skill.
• Accept zero traces as a complete, valid result. Do not search for or invent sample traces merely to populate a new environment.
• Build only into a user-scoped absolute output path. The builder refuses unrelated non-empty directories and paths inside the skill.
• Validate locally before publishing.
• Create, replace, or delete a NorthJetty route only when the user explicitly requests a live-state change.
• Use --require-auth unless the user explicitly requests a public route and understands the exposure.
• Never repeat secrets in the final response. The publisher API key and viewer access code are different credentials.

Resolve bundled tools

Resolve SKILL_DIR to the directory containing this SKILL.md, then use:

• scripts/build_trace_site.py to initialize or rebuild a site.
• scripts/validate_trace_site.py to check its manifest and all chunks.
• scripts/nj-publish.py with sibling scripts/njsite.py to manage NorthJetty.
• assets/index.html as the generic zero-data Viewer template.

Read references/operations.md before publishing, changing authentication, handling a large trace, or diagnosing a dead route.

Build workflow

1. Resolve the requested output directory and trace sources. If no trace source was supplied, build an empty viewer without asking for placeholder data.
2. For trace-backed builds, inspect only the supplied paths. Prefer .trace.json.gz; raw .trace.json also works.
3. Build the site:

python3 "$SKILL_DIR/scripts/build_trace_site.py" \
  --output /absolute/path/to/trace-site \
  --title "Team Torch Trace Viewer"

Add one or more runtime groups when traces exist:

python3 "$SKILL_DIR/scripts/build_trace_site.py" \
  --output /absolute/path/to/trace-site \
  --title "Model traces" \
  --group prefill=/absolute/path/to/prefill \
  --group decode=/absolute/path/to/decode \
  --group-label "prefill=Prefill" \
  --group-label "decode=Decode"

4. Validate every build:

python3 "$SKILL_DIR/scripts/validate_trace_site.py" /absolute/path/to/trace-site

Treat Groups: 0, Traces: 0, and Validation: OK as success for a clean environment.

Publish workflow

Publish only after local validation and explicit user authorization:

python3 "$SKILL_DIR/scripts/nj-publish.py" start \
  /absolute/path/to/trace-site \
  --alias team-torch-trace \
  --require-auth

Let the client securely prompt for NORTHJETTY_API_KEY; do not put the key in a command or file. start backgrounds itself. Preserve the printed public URL, but tell the user to retrieve and share the route access code through the local publisher output or log rather than reproducing it in chat.

Verify the route state:

python3 "$SKILL_DIR/scripts/nj-publish.py" list

For updates, rebuild the same generated output and re-run validation; the static server serves refreshed files without route recreation. For lifecycle work, use logs <alias> and stop <alias> only within the user's requested scope.

Handoff

Report:

• generated site path;
• whether the site is empty or the exact group/trace counts;
• local validation result;
• route alias and public URL when published;
• that the access code remains secret and where the user can retrieve it;
• the remote Perfetto dependency when trace confidentiality matters.
