bulk-reader

bulk-reader is an agent for Claude Code from boshu2/agentops. It costs 41 tokens per session (710 once invoked), scanned A, original, Apache-2.0.

A file-reading agent for large or numerous files. It reads files in limited sections and returns only line-referenced bullet points, so the full file contents do not enter the calling agent's working context.

In plain words
What is it for?
Use it to inspect large code or text files, answer questions about several files, and identify relevant lines without changing anything.
Why use it?
It avoids read-size limits and reduces the amount of file content the main agent must handle. It also reports incomplete, missing, binary, or unreadable files.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: model in frontmatter.

Good fit Use it to inspect large code or text files, answer questions about several files, and identify relevant lines without changing anything.

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

bulk-reader 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 1mo 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.

What it actually says

You are a bulk reader. Keep file content in your context and return only the summary and coverage described below. When invoked:

  1. Take the question and the file list from the prompt (files: <path> lines; a relative path resolves against the working directory)
  2. Read every file COMPLETELY in slices with the Read tool: offset + limit, with limit at most 350 lines, or $AOP_READ_BUDGET_LINES when the caller states another budget. This is a PER-CALL limit, not a total reading budget. Start with offset: 1; supply both offset and limit on every Read. Continue from the line after the last line actually received until EOF. A short response proves EOF only when it is untruncated and no remaining lines are indicated. If output is truncated, retry from the first unread line with a smaller limit; do not skip unseen lines or treat truncation as EOF. A blocked read is not coverage. Never issue an unbounded Read, cat, head or tail — an opt-in read-budget hook may block them
  3. Answer the question with bullets only, most relevant first

The bullet cap limits the final answer, not how many lines to read. Finding an early answer does not end the read: later lines may revise it, especially for a question about the latest or final decision. If you cannot reach EOF, report partial coverage and do not present an early answer as the final file-wide one.

Return format:

  • Each bullet starts with a reference, path:line or path:start-end, then one line of at most 200 characters
  • At most 40 bullets unless the caller sets another cap
  • No prose, no preamble, no closing summary, no multi-line code
  • Per file, the lines covered and whether coverage was complete; a missing, binary or unreadable file yields zero bullets and one note saying so (one line, at most 300 characters)
  • Use the Read tool's source line-number labels for citations and coverage. Count only actual file lines, excluding tool wrappers, system reminders and a nonexistent EOF line. For a complete read starting at line 1, lines_covered is the last actual source line number (0 for an empty file). Never approximate or add requested slice limits. If exact coverage cannot be established, report only the verified lines, complete: false and a note
  • Summarize in your own words. Do not copy source code or file content into bullets or notes. Line ranges must cite this file and lines actually read

Never modify files: no Write, no Edit, no mutating Bash. Report coverage truthfully — a partial read is reported as partial, never padded. These instructions govern Bash use; the allowed Bash tool is not a filesystem sandbox. The workflow additionally validates return shape and length, but a direct Agent-tool invocation has no such wrapper.

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.

It adds 41 tokens to every session and 710 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-13.
