Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00045 | $0.00785 |
| Opus 5 | $0.00023 | $0.00392 |
| Sonnet 5 | $0.00009 | $0.00157 |
| Haiku 4.5 | $0.00005 | $0.00078 |
Grade A, and why
codeindex-debugging scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Debugging with CodeIndex
When to Use
- "Why is this function failing?"
- "Trace where this error comes from"
- "Who calls this method?"
- "This endpoint returns 500"
- Investigating bugs, errors, or unexpected behavior
Workflow
1. codeindex_query({query: "<error or symptom>"}) → Find related execution flows
2. codeindex_context({name: "<suspect>"}) → See callers/callees/processes
3. READ codeindex://repo/{name}/process/{name} → Trace execution flow
4. codeindex_cypher({query: "MATCH path..."}) → Custom traces if needed
In Conductor worktrees, "Index is stale" can be an overlay/canonical-checkout mismatch. Use
scripts/codeindex-health.sh; only runscripts/codeindex-health.sh --repairwhen it reports the shared base index is stale. Verify branch-local code with source files/diffs.
Checklist
- [ ] Understand the symptom (error message, unexpected behavior)
- [ ] codeindex_query for error text or related code
- [ ] Identify the suspect function from returned processes
- [ ] codeindex_context to see callers and callees
- [ ] Trace execution flow via process resource if applicable
- [ ] codeindex_cypher for custom call chain traces if needed
- [ ] Read source files to confirm root cause
Debugging Patterns
| Symptom | CodeIndex Approach |
|---|---|
| Error message | codeindex_query for error text → context on throw sites |
| Wrong return value | context on the function → trace callees for data flow |
| Intermittent failure | context → look for external calls, async deps |
| Performance issue | context → find symbols with many callers (hot paths) |
| Recent regression | detect_changes to see what your changes affect |
Tools
codeindex_query — find code related to error:
codeindex_query({query: "payment validation error"})
→ Processes: CheckoutFlow, ErrorHandling
→ Symbols: validatePayment, handlePaymentError, PaymentException
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

codeindex-debugging is a skill published in the GitHub repository GetKlai/klai (11 stars, last pushed 2d ago), licensed MIT. It adds 45 tokens to every session and 785 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
