vera

vera is a skill for Claude Code, Codex from VeraTools/Vera. It costs 96 tokens per session (806 once invoked), scanned A, original, MIT.

A repository search tool that ranks code results by relevance. It can search for behavior, exact text, code structure, definitions, routes, environment-variable reads, and references between functions.

In plain words
What is it for?
Use it to find where code lives, understand how it works, locate exact strings, trace callers, and find routes or configuration reads. It is intended for searching the current repository.
Why use it?
It reduces the need to open many files while trying to understand an unfamiliar codebase. More focused searches can show where behavior is implemented and used.

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

vera 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 3d 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 — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Vera

Ranked code search over an indexed repository. Results are markdown codeblocks: path:line_start-line_end symbol_type:symbol_name, then the code.

Pick the tool

You are about to... Do this instead
Read files to find where something lives vera search "config object construction"
Read files to understand how something works vera search "env file loading decision"
Find documentation on a topic vera search "deploying behind proxy" --scope docs
Find every occurrence of a pattern vera grep "TODO|FIXME"
Find callers or callees of a symbol vera references make_config
Find definitions, routes, env reads vera structural env / vera structural routes
Edit the same pattern in many files rg
Read a file you already know Read it directly

Do not use Vera when

  • You already know the exact path and line: open the file.
  • You are editing across many files mechanically: use rg.
  • The answer is a literal string you can match: vera grep beats vera search.
  • You have already run two searches that returned the same region: stop searching and read the code.

Search well

  • Search behavior, not nouns: "JWT expiry handling", not "auth" or "utils".
  • Pass several angles in one call: vera search "OAuth token refresh" "JWT expiry" "auth middleware".
  • Start broad with --compact (signatures only, fewer tokens), then narrow with --lang, --path, --type, --limit.
  • Add --intent "<goal>" when the query is vague but the goal is clear.
  • Scope to a change with --changed, --since <rev>, or --base <rev> when reviewing a diff.
  • --deep rewrites the query through an LLM; use it only after normal search misses.

Treat hits as leads

  • A search hit is a lead, not evidence. Before stating how something behaves, open the cited lines.
  • Follow the call graph rather than re-searching: vera references <symbol> on a promising hit answers "who drives this" in one step.
  • Cite path:line from code you actually read.
  • After editing files, run vera update . before searching again.

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.

vera is a skill published in the GitHub repository VeraTools/Vera (106 stars, last pushed 4d ago), licensed MIT. It adds 96 tokens to every session and 806 once invoked, about $0.0005 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.
