|

## Your task — 6-step triage workflow
|
||||
|
||||
You have a defined 6-step workflow to follow. Budget your turns: ~70% on tracing, ~30% on instrumentation.
|
||||
|
||||
### Step 1: Read reproduce-agent findings
|
||||
Before doing anything else, parse all prior evidence from the issue comments.
|
||||
|
||||
1. Fetch the issue body and all comments:
|
||||
curl -sf -H "Authorization: token \${FORGE_TOKEN}" \
|
||||
"\${FORGE_API}/issues/\${ISSUE_NUMBER}" | jq -r '.body'
|
||||
curl -sf -H "Authorization: token \${FORGE_TOKEN}" \
|
||||
"\${FORGE_API}/issues/\${ISSUE_NUMBER}/comments" | jq -r '.[].body'
|
||||
|
||||
2. Identify the reproduce-agent comment (look for sections like
|
||||
"Reproduction steps", "Logs examined", "What was tried").
|
||||
|
||||
3. Extract and note:
|
||||
- The exact symptom (error message, unexpected value, visual regression)
|
||||
- Steps that reliably trigger the bug
|
||||
- Log lines or API responses already captured
|
||||
- Any hypotheses the reproduce-agent already ruled out
|
||||
|
||||
Do NOT repeat work the reproduce-agent already did. Your job starts where
|
||||
theirs ended. If no reproduce-agent comment is found, note it and proceed
|
||||
with fresh investigation using the issue body only.
|
||||
|
||||
### Step 2: Trace data flow from symptom to source
|
||||
Systematically follow the symptom backwards through each layer of the stack.
|
||||
|
||||
Generic layer traversal: UI → API → backend → data store
|
||||
|
||||
For each layer boundary:
|
||||
1. What does the upstream layer send?
|
||||
2. What does the downstream layer expect?
|
||||
3. Is there a mismatch? If yes — is this the root cause or a symptom?
|
||||
|
||||
Tracing checklist:
|
||||
a. Start at the layer closest to the visible symptom.
|
||||
b. Read the relevant source files — do not guess data shapes.
|
||||
c. Cross-reference API contracts: compare what the code sends vs what it
|
||||
should send according to schemas, type definitions, or documentation.
|
||||
d. Check recent git history on suspicious files:
|
||||
git log --oneline -20 -- <file>
|
||||
e. Search for related issues or TODOs in the code:
|
||||
grep -r "TODO\|FIXME\|HACK" -- <relevant directory>
|
||||
|
||||
Capture for each layer:
|
||||
- The data shape flowing in and out (field names, types, nullability)
|
||||
- Whether the layer's behavior matches its documented contract
|
||||
- Any discrepancy found
|
||||
|
||||
If a clear root cause becomes obvious during tracing, note it and continue
|
||||
checking whether additional causes exist downstream.
|
||||
|
||||
### Step 3: Add debug instrumentation on a throwaway branch
|
||||
Use ~30% of your total turn budget here. Only instrument after tracing has
|
||||
identified the most likely failure points — do not instrument blindly.
|
||||
|
||||
1. Create a throwaway debug branch (NEVER commit this to main):
|
||||
cd "\$PROJECT_REPO_ROOT"
|
||||
git checkout -b debug/triage-\${ISSUE_NUMBER}
|
||||
|
||||
2. Add targeted logging at the layer boundaries identified during tracing:
|
||||
- Console.log / structured log statements around the suspicious code path
|
||||
- Log the actual values flowing through: inputs, outputs, intermediate state
|
||||
- Add verbose mode flags if the stack supports them
|
||||
- Keep instrumentation minimal — only what confirms or refutes the hypothesis
|
||||
|
||||
3. Restart the stack using the configured script (if set):
|
||||
\${stack_script:-"# No stack_script configured — restart manually or connect to staging"}
|
||||
|
||||
4. Re-run the reproduction steps from the reproduce-agent findings.
|
||||
|
||||
5. Observe and capture new output:
|
||||
- Paste relevant log lines into your working notes
|
||||
- Note whether the observed values match or contradict the hypothesis
|
||||
|
||||
6. If the first instrumentation pass is inconclusive, iterate:
|
||||
- Narrow the scope to the next most suspicious boundary
|
||||
- Re-instrument, restart, re-run
|
||||
- Maximum 2-3 instrumentation rounds before declaring inconclusive
|
||||
|
||||
Do NOT push the debug branch. It will be deleted in the cleanup step.
|
||||
|
||||
### Step 4: Decompose root causes into backlog issues
|
||||
After tracing and instrumentation, articulate each distinct root cause.
|
||||
|
||||
For each root cause found:
|
||||
|
||||
1. Determine the relationship to other causes:
|
||||
- Layered (one causes another) → use Depends-on in the issue body
|
||||
- Independent (separate code paths fail independently) → use Related
|
||||
|
||||
2. Create a backlog issue for each root cause:
|
||||
curl -sf -X POST "\${FORGE_API}/issues" \\
|
||||
-H "Authorization: token \${FORGE_TOKEN}" \\
|
||||
-H "Content-Type: application/json" \\
|
||||
-d '{
|
||||
"title": "fix: <specific description of root cause N>",
|
||||
"body": "## Root cause\\n<exact code path, file:line>\\n\\n## Fix suggestion\\n<recommended approach>\\n\\n## Context\\nDecomposed from #\${ISSUE_NUMBER} (cause N of M)\\n\\n## Dependencies\\n<#X if this depends on another cause being fixed first>",
|
||||
"labels": ["backlog"]
|
||||
}'
|
||||
|
||||
3. Note the newly created issue numbers.
|
||||
|
||||
If only one root cause is found, still create a single backlog issue with
|
||||
the specific code location and fix suggestion.
|
||||
|
||||
If the investigation is inconclusive (no clear root cause found), skip this
|
||||
step and proceed directly to link-back with the inconclusive outcome.
|
||||
|
||||
### Step 5: Update original issue and relabel
|
||||
Post a summary comment on the original issue and update its labels.
|
||||
|
||||
#### If root causes were found (conclusive):
|
||||
|
||||
Post a comment:
|
||||
"## Triage findings
|
||||
|
||||
Found N root cause(s):
|
||||
- #X — <one-line description> (cause 1 of N)
|
||||
- #Y — <one-line description> (cause 2 of N, depends on #X)
|
||||
|
||||
Data flow traced: <layer where the bug originates>
|
||||
Instrumentation: <key log output that confirmed the cause>
|
||||
|
||||
Next step: backlog issues above will be implemented in dependency order."
|
||||
|
||||
Then swap labels:
|
||||
- Remove: in-triage
|
||||
- Add: in-progress
|
||||
|
||||
#### If investigation was inconclusive (turn budget exhausted):
|
||||
|
||||
Post a comment:
|
||||
"## Triage — inconclusive
|
||||
|
||||
Traced: <layers checked>
|
||||
Tried: <instrumentation attempts and what they showed>
|
||||
Hypothesis: <best guess at cause, if any>
|
||||
|
||||
No definitive root cause identified. Leaving in-triage for supervisor
|
||||
to handle as a stale triage session."
|
||||
|
||||
Do NOT relabel. Leave in-triage. The supervisor monitors stale triage
|
||||
sessions and will escalate or reassign.
|
||||
|
||||
### Step 6: Delete throwaway debug branch
|
||||
Always delete the debug branch, even if the investigation was inconclusive.
|
||||
|
||||
1. Switch back to the main branch:
|
||||
cd "\$PROJECT_REPO_ROOT"
|
||||
git checkout "\$PRIMARY_BRANCH"
|
||||
|
||||
2. Delete the local debug branch:
|
||||
git branch -D debug/triage-\${ISSUE_NUMBER}
|
||||
|
||||
3. Confirm no remote was pushed (if accidentally pushed, delete it too):
|
||||
git push origin --delete debug/triage-\${ISSUE_NUMBER} 2>/dev/null || true
|
||||
|
||||
4. Verify the worktree is clean:
|
||||
git status
|
||||
git worktree list
|
||||
|
||||
A clean repo is a prerequisite for the next dev-agent run. Never leave
|
||||
debug branches behind — they accumulate and pollute the branch list.
|
||||

||||
## Notes
|
||||
- The application is accessible at localhost (network_mode: host)
|
||||
- Budget: 70% tracing data flow, 30% instrumented re-runs
|
||||
- Timeout: \${FORMULA_TIMEOUT_MINUTES} minutes total (or until turn limit)
|
||||
- Stack lock is held for the full run
|
||||
- If stack_script is empty, connect to existing staging environment
