Engram: Instructions file for Codex

AGENTS.md

Engram AGENTS.md is an instructions file for Codex, OpenCode from bobaba76/Engram. It costs 736 tokens per session, scanned A, original, MIT.

Repository instructions for Engram that define how to use its coder MCP, a tool for understanding code structure. They cover finding symbols, tracing dependencies, checking change impact, and locating tests.

In plain words
What is it for?
Use them when exploring code, finding the implementation of a feature, tracing dependencies, assessing a proposed change, or identifying tests for a function, route, API, or shared module.
Why use it?
They tell the agent where to look before modifying important code. This helps avoid missing callers, related modules, or relevant tests in an unfamiliar repository.

Written for Codex and OpenCode: the file is AGENTS.md.

This is bobaba76/Engram's own configuration. It tells Codex and OpenCode how to work on Engram 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 Engram 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 A, and why

Engram AGENTS.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 2mo 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.

coder MCP - Primary Code Intelligence

This project uses coder MCP as the primary code-intelligence layer for codebase discovery, symbol lookup, dependency tracing, impact review, test discovery, and implementation context.

Prefer coder MCP for this repository. Use other code-intelligence tools only as optional fallbacks or secondary cross-checks when coder MCP cannot answer a question clearly.

Always Do

  • Use coder MCP first when you need to locate files, symbols, routes, tests, dependencies, execution context, or likely implementation areas.
  • Use coder_semantic_code_search or coder_investigate_codebase when exploring unfamiliar features or trying to find the authoritative implementation.
  • Use coder_resolve_target and coder_unified_context when you need focused symbol-level context (callers, callees, deps, neighborhood in one call).
  • Before modifying a function, class, method, route handler, shared module, public header, API contract, or embedded firmware boundary, use coder MCP to inspect symbol context, callers/callees, dependencies, or change impact as appropriate.
  • Use coder_find_tests_for_target before or after implementation to identify relevant tests.
  • Use coder_detect_changes, coder_change_impact_report, or coder_post_change_review to review changed files, likely affected behavior, and test scope when preparing a commit or handoff.
  • For C/C++/embedded projects, use coder_get_dependencies, coder_unified_context, and coder_detect_changes to inspect header fan-in, call relationships, project/build files, startup/ISR/trap files, and peripheral/init/flash modules.
  • If coder MCP reports stale, incomplete, or low-confidence results, use normal file search/read tools or another code-intelligence system as a fallback.

Never Do

  • NEVER skip reviewing callers, dependencies, or likely test scope for changes to shared or high-risk code.
  • NEVER commit or hand off changes without reviewing local change scope using coder MCP or equivalent git diff inspection.
  • NEVER ignore low-confidence C/C++ results when compiler/build context is missing. Treat them as useful guidance, then verify with source and build knowledge.

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.
