What it does

Vera is an agent skill from VeraTools/vera. Code search over the current repository. Before reading files to answer "where is X", "how does Y work", "find Z", or "what calls W", run vera search "<query" or vera references <symbol first. Use vera grep for exact strings and regex, vera structural for definitions, routes, and env reads. Do not read multiple files hoping to find the right one; search first, then read the hit.

Its SKILL.md is about 830 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in AI & LLM Engineering, covering Codebase onboarding and Retrieval-augmented generation. It works with Model Context Protocol, Rust and ONNX. The repository describes itself as: Local code search combining BM25, vector similarity, and cross-encoder reranking. Parses 60+ languages with tree-sitter, runs entirely offline, and returns structured results… The licence is MIT.

When your agent uses it

  • Tasks that involve Codebase onboarding
  • Tasks that involve Retrieval-augmented generation

Example prompts

  • “where is X”
  • “how does Y work”
  • “find Z”
  • “/vera”

What it can do on your machine

Read from SKILL.md and the folder at commit 6cb92d5. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Vera loads about 825 tokens when it runs. Until then it costs about 99 tokens; SKILL.md has 386 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~99
When it runs · the whole SKILL.md, loaded when a task matches
~825

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Code search over the current repository. Before reading files to answer "where is X", "how does Y work", "find Z", or "what calls W", run `vera search "<query>"` or `vera references <symbol>` first. Use `vera grep` for exact strings and regex, `vera structural` for definitions, routes, and env reads. Do not read multiple files hoping to find the right one; search first, then read the hit.

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 livesvera search "config object construction"
Read files to understand how something worksvera search "env file loading decision"
Find documentation on a topicvera search "deploying behind proxy" --scope docs
Find every occurrence of a patternvera grep "TODO|FIXME"
Find callers or callees of a symbolvera references make_config
Find definitions, routes, env readsvera structural env / vera structural routes
Edit the same pattern in many filesrg
Read a file you already knowRead 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.

Can I use Vera in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add VeraTools/vera --skill vera -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/vera, .gemini/skills/vera, .github/skills/vera and .opencode/skills/vera in your project.

What does Vera need to run?

SKILL.md names no scripts, command-line tools or credentials: Vera is instructions for the agent only.

Does Vera access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Vera safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Vera use?

Vera is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Vera use?

About 825 tokens (SKILL.md is roughly 3.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Vera?
