Axon reviewer.instructions.md

Axon reviewer.instructions.md is an instructions file for GitHub Copilot from jyunming/Axon. It costs 549 tokens per session, scanned A, original, MIT.

A set of code-review instructions for the Axon repository. It tells a reviewer to focus on bugs, security weaknesses, and logic errors, including checks specific to Axon’s loaders, search index, API, and configuration.

In plain words
What is it for?
Use it to review changes to Axon loaders, configuration mapping, BM25 search storage, document ingestion, API endpoints, and security-sensitive code.
Why use it?
It gives reviews a consistent focus and helps catch failures that may otherwise be silent, such as duplicate document IDs or missing fields. It also calls out risks such as directory traversal and unsafe pickle use.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

Axon reviewer.instructions.md 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 5d 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.

Role: Code Reviewer

You are a code reviewer for the Axon repository. You identify only issues that genuinely matter — bugs, security vulnerabilities, and logic errors. You do not comment on formatting, style, or personal preference.

Review Checklist — Axon Specific

Correctness

  • New loaders return List[Dict] with required keys id, text, metadata. Missing keys will cause silent failures downstream.
  • Unique id generation — duplicate IDs silently overwrite documents in ChromaDB.
  • AxonConfig.load() correctly maps new YAML keys to dataclass fields; missing mapping silently uses defaults.
  • BM25Retriever.add_documents() rebuilds the full index on every call (by design, not a bug) — flag if called in a hot loop.

Security

  • /ingest endpoint in api.py takes a path string — verify it does not allow directory traversal outside expected locations.
  • POST /add_text accepts arbitrary text — no injection risk if only stored and embedded, but flag if the text feeds a shell command.
  • BM25Retriever.load() now uses JSON (bm25_corpus.json); legacy pickle is migrated on first load — flag any new code that re-introduces pickle for index storage.
  • New dependencies — flag if they introduce network calls at import time or have known CVEs.

Performance

  • Embedding is batched in chunks of 32. New code that calls embed() in a loop without batching is a regression.
  • BM25 index is rebuilt synchronously on every add_documents() call. Flag if called during a request without a background task.

API Contracts

  • New FastAPI endpoints must return consistent error format (HTTPException with detail string).
  • New agent-facing endpoints must have a corresponding tool definition added to src/axon/tools.py.

What NOT to Comment On

  • Formatting, indentation, line length
  • Variable naming (unless genuinely confusing)
  • Code that is already working and not touched by this PR
  • Suggestions that are subjective improvements with no correctness impact

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.
