debug

Purpose

Root cause analysis ONLY. Debug investigates — it does NOT fix. It traces errors through code, analyzes stack traces, forms and tests hypotheses, and identifies the exact cause before handing off to rune:fix.

Do NOT fix the code. Debug investigates only. Any code change is out of scope. If root cause cannot be identified after 3 hypothesis cycles:

Emit agent.stuck signal — scout zoom-out mode surfaces broader module map (structural pivot); adversary oracle-mode dispatches a stateless second-model pass (semantic pivot); both fire in parallel

If oracle.response arrives with confidence=high and cites file:line, treat as new hypothesis H_oracle and test directly (skip 3-cycle gate — it's externally validated)

Otherwise, escalate to rune:problem-solver for structured 5-Whys or Fishbone analysis

Or escalate to rune:sequential-thinking for multi-variable analysis

Report escalation in the Debug Report with all evidence gathered so far

Triggers

Called by cook when implementation hits unexpected errors
Called by test when a test fails with unclear reason
Called by fix when root cause is unclear before fixing
/rune debug <issue> — manual debugging
Auto-trigger: when error output contains stack trace or error code

Calls (outbound)

scout (L2): find related code, trace imports, identify affected modules
fix (L2): when root cause found, hand off with diagnosis for fix application
brainstorm (L2): 3-Fix Escalation when root cause is "wrong approach" — invoke with mode="rescue" for category-diverse alternatives
plan (L2): 3-Fix Escalation when root cause is "wrong module design" — invoke for redesign
docs-seeker (L3): lookup API docs for unclear errors or deprecated APIs
problem-solver (L3): structured reasoning (5 Whys, Fishbone) for complex bugs
browser-pilot (L3): capture browser console errors, network failures, visual bugs
sequential-thinking (L3): multi-variable root cause analysis
neural-memory (L3): after root cause found — capture error pattern for future recognition
adversary (L2): on agent.stuck — oracle-mode dispatches stateless second-model pass to break confirmation-bias loop (parallel with scout zoom-out)

Called By (inbound)

cook (L1): implementation hits bug during Phase 4
fix (L2): root cause unclear, can't fix blindly — needs diagnosis first
test (L2): test fails unexpectedly, unclear why
surgeon (L2): diagnose issues in legacy modules

Cross-Hub Connections

debug ↔ fix — bidirectional: debug finds cause → fix applies, fix can't determine cause → debug investigates
debug ← test — test fails → debug investigates

Execution

Step 0: Build a Feedback Loop (the actual skill)

The loop is the speed limit. A fast, deterministic, agent-runnable pass/fail signal turns debugging into mechanical bisection. Without one, hypotheses just consume noise.

Skip Step 0 only if the existing repro is already one command, deterministic, and runs in < 5s.

Otherwise, before Step 1: pick the highest viable rung from references/feedback-loop-ladder.md (10-rank ladder: failing test → curl → CLI snapshot → headless browser → trace replay → throwaway harness → fuzz → bisection → differential → HITL script). Construct it. Verify it currently FAILS (proves it measures the bug, not noise). Only then proceed.

If loop construction takes > 10 minutes, that itself is the diagnosis: the bug surface is too large or the system too coupled. Trigger the 3-Fix Escalation Rule (Step 6) — architecture is the problem, not the bug.

Step 1: Reproduce

Understand and confirm the error described in the request.

Read the error message, stack trace, and reproduction steps
Identify which environment it occurs in (dev/prod, browser/server)
Confirm the error is consistent and reproducible before proceeding
If no reproduction steps provided, ask for them or attempt the most likely path

Step 1.5: Scope Lock (Edit Boundary)

After reproducing the error, lock edits to the narrowest affected directory to prevent debug-driven scope creep — the #1 source of "while I'm here, let me also fix..." violations.

Identify the narrowest directory containing the affected files (from stack trace or error location)
Announce to user: "Debug scope locked to <dir>/. Changes will be restricted to this area."
Any fix recommendation in the Debug Report MUST reference only files within this boundary
If root cause traces outside the boundary → expand scope with user confirmation first

Skip conditions (do NOT lock):

Bug spans the entire repo (3+ unrelated directories in stack trace)
Cannot determine affected area from initial evidence
User explicitly says "investigate everything"

Why: Debugging naturally expands scope as you trace root causes. Without a boundary, rune:fix receives recommendations touching 10+ files across unrelated modules. The scope lock forces discipline: fix at the source, not at every symptom site.

Step 2: Gather Evidence

Use tools to collect facts — do NOT guess yet.

Use Grep to search codebase for the exact error string or related error codes
Use Read to examine stack trace files, log files, or the specific file:line mentioned
Use Glob to find related files (config, types, tests) that may be involved
Use rune:browser-pilot if the issue is UI-related (console errors, network failures, visual bugs)
Use rune:scout to trace imports and identify all modules touched by the affected code path

Backward Tracing (for deep stack errors)

When the error appears deep in execution (wrong directory, wrong path, wrong value):

Observe symptom — what's the exact error and where does it appear?
Find immediate cause — what code directly triggers this? Read that file:line
What called this? — trace one level up. What value was passed? By whom?
Keep tracing up — repeat until you find where the bad value ORIGINATES
Fix at source — the root cause is where invalid data is CREATED, not where it CRASHES

Rule: NEVER fix where the error appears. Trace back to where invalid data originated.

Instrumentation Tip: Use console.error, Not Loggers

When adding diagnostic instrumentation, use console.error() (stderr) — NOT application loggers. Loggers are configured to suppress output based on log level or environment (e.g., LOG_LEVEL=warn silences logger.debug). console.error bypasses all logger configuration and writes directly to stderr. This is counterintuitive but critical — the one time you NEED debug output is exactly when loggers are configured to hide it.

Defense-in-Depth (After Root Cause Found)

When the root cause is invalid data flowing through multiple layers, recommend fixing at ALL layers — not just the source:

Layer	Purpose	Example
Layer 1: Entry Point	Reject invalid input at API/CLI boundary	Validate not empty, exists, correct type
Layer 2: Business Logic	Ensure data makes sense for the operation	Validate required params before processing
Layer 3: Environment Guards	Prevent dangerous operations in specific contexts	Refuse destructive ops outside allowed dirs
Layer 4: Debug Instrumentation	Capture context for forensics	Stack trace logging before dangerous operations

All four layers are necessary. During testing, each layer catches bugs the others miss — different code paths bypass single validation points. When recommending a fix via rune:fix, explicitly call out which layers need validation added.

Multi-Component Instrumentation (for systems with 3+ layers)

When the system has multiple components (CI → build → deploy, API → service → DB):

Before hypothesizing, add diagnostic logging at EACH component boundary:

Log what data ENTERS each component
Log what data EXITS each component
Verify environment/config propagation across boundaries
Run once → analyze logs → identify WHICH boundary fails → THEN hypothesize

This reveals: "secrets reach workflow ✓, workflow reaches build ✗" — pinpoints the failing layer.

Step 2b: Instrument with Preserved Markers

When adding diagnostic logging or instrumentation during investigation, mark ALL additions with region markers:

// #region agent-debug — [hypothesis being tested]
console.log('[DEBUG] value at boundary:', data);
// #endregion agent-debug

Language-appropriate equivalents:

Python: # region agent-debug / # endregion agent-debug
Rust: // region agent-debug / // endregion agent-debug

Why preserved markers matter:

rune:fix will preserve these markers until the bug is fully resolved and tests pass
If the bug recurs, markers show exactly what was previously instrumented
Cleaning up debug traces before the fix is verified prevents learning from failure history
After fix is verified + tests pass → fix will clean up markers in a final pass

ALL diagnostic code added during debug MUST be wrapped in #region agent-debug markers. Unmarked instrumentation will be treated as stray code and removed prematurely.

Observability gap as a finding. If you had to add temporary console.log markers because the code emitted nothing useful about this path, that absence is itself a root-cause-adjacent signal: the bug was hard to diagnose because the system is blind here. When the fix lands, recommend converting the throwaway markers into durable structured telemetry (a stable event name + correlation ID, not prose) so the next occurrence is a query, not another archaeology session. This is advisory — note it in the report, don't block on it. Contract: ../deploy/references/observability.md.

Step 2c: Check Debug Knowledge Base

Before forming hypotheses, check .rune/debug/knowledge-base.md:

If file exists → search for matching symptoms/error messages
If match found → try known fix FIRST, skip hypothesis cycle
If no match → proceed to Step 3

After successful root cause identification (Step 5), append entry:

### [date] — [symptom summary]
- **Symptom**: [error message or behavior]
- **Root Cause**: [what was actually wrong]
- **Fix**: [what resolved it]
- **Files**: [affected files]

This prevents re-debugging the same issue across sessions.

Step 2d: Known Error Pattern Matching

Before forming hypotheses, match the error against common error archetypes. If a match is found, skip directly to the known fix approach — no hypothesis cycling needed.

Error Pattern Catalog:

Pattern ID	Detection (Error Type + Keywords)	Root Cause	Recovery Hint
`STATELESS_LOSS`	`NameError` / `ReferenceError` + variable defined in previous step	Execution context doesn't persist between tool calls	"Combine all variable definitions and usage in a single code block"
`MODULE_NOT_FOUND`	`ModuleNotFoundError` / `Cannot find module`	Dependency not installed or wrong import path	"Check package.json/requirements.txt. Install missing dep, then retr

### Step 0: Build a Feedback Loop (the actual skill)
<MUST-READ path="references/feedback-loop-ladder.md" trigger="when current repro is not a single command returning pass/fail in <5s, or when bug is intermittent/multi-component"/>
