trs: Instructions file for Codex

AGENTS.md

trs AGENTS.md is an instructions file for Codex, OpenCode from dPeluChe/trs. It costs 1,587 tokens per session, scanned B, original, MIT.

Instructions for trs, a Rust command-line tool that turns lengthy terminal output into shorter structured summaries. They also describe a pre-generated digest that maps the codebase for an agent.

In plain words
What is it for?
Use it to reduce terminal output, view command-savings statistics, check trs and instruction-file health, find duplicated or misplaced content in agent guides, and regenerate the project digest before a release.
Why use it?
Noisy command output and oversized instruction files take up context that an agent could use for the task itself. These instructions explain how to inspect savings, check installation health, audit agent documentation, and refresh the codebase digest.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions AGENTS.md; mentions Cursor.

This is dPeluChe/trs's own configuration. It tells Codex and OpenCode how to work on trs itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything trs configures →

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 B, and why

trs AGENTS.md scanned grade B with 2 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.

AGENTS.md: trs (Token-Reducing Shell)

What is trs

A Rust CLI that transforms noisy terminal output into compact, structured signal. Cuts ~70% of the tokens AI agents spend on terminal output, measured on real sessions (see docs/development/benchmarks/).

Pre-generated codebase digest

docs/development/codebase-digest.md is a snapshot of the entire trs codebase produced by trs ingest. Drop it into any agent's context for an instant map of the project without having to run trs ingest yourself.

The digest can drift from HEAD between releases. Regenerate before tagging a release, or whenever src/ has moved meaningfully.

Run ./scripts/sync-codebase-digest.sh. It uses trs from PATH and falls back to ./target/release/trs if one isn't installed.

  • trs stats: cumulative savings across commands (shows date range, today vs. average, last command, top-reducers).
  • trs doctor: installation health check. Warns when AGENTS.md / CLAUDE.md exceed ~5k tokens and points at trs audit-docs.
  • trs audit-docs: static analysis of agent instruction files (CLAUDE.md, AGENTS.md, rules files). Surfaces cross-file duplicates, embedded code/SQL/JSON blocks that belong elsewhere, dead @imports, and (for code fences) cross-references declared symbols against the actual source tree (so you can REMOVE ones already defined in src/ and EXTRACT ones that don't live anywhere yet).
  • trs output-saver: install a short output-reduction rules block into each agent's global config (AGENTS.md / CLAUDE.md / Cursor rules). Closes the symmetric gap: trs compresses what agents SEE via trs rewrite; output-saver compresses what they EMIT via anti-preamble / anti-narration / structured-output directives. Check-first by default (--install to commit, --remove to undo).
  • trs ingest: project digest for LLM consumption. Use symbol index, compression levels, or owner/repo URL shorthand.
  • trs init --show: see which AI agents have trs hooks installed.
  • trs upgrade: detects the install channel (npm / curl) and re-runs it for the latest release. --check dry-runs, -y skips the confirmation prompt. See docs/features/upgrade.md.
  • trs init <tool>: now runs a collision pre-check: detects hooks from other token-compression tools (via @imports too) and aborts by default. --replace removes competitor hooks cleanly, --force installs alongside (risky, double-compression can corrupt output). See docs/support/other-token-savers.md for the list of tools we coexist with.
  • trs stats --by-agent: breakdown by which AI agent fired each rewrite. Reads the TRS_AGENT env var that trs rewrite and plugin templates inject into the command line. Rules-only agents and direct shell runs show as (untagged).
  • TRS_SKIP=1 prefix: per-invocation bypass. Agents (or users) that need raw output for a specific command can prefix TRS_SKIP=1 <cmd>; trs rewrite passes it through unchanged.

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.

trs AGENTS.md is an instructions file published in the GitHub repository dPeluChe/trs (14 stars, last pushed 7d ago), licensed MIT. It adds 1,587 tokens to every session, about $0.0063 per session on Opus 5.5. A static security scan graded it B with 2 findings (asks the agent to reveal its instructions, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
