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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01124 | $0.01124 |
| Opus 5 | $0.00562 | $0.00562 |
| Sonnet 5 | $0.00225 | $0.00225 |
| Haiku 4.5 | $0.00112 | $0.00112 |
Grade A, and why
Nreki 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 8d 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.

AGENTS.md
Instructions for AI coding agents consuming NREKI via MCP (Codex, Gemini, others)
0. ZERO-CHATTER
- Call tools immediately. No "I will now..." or "Let me...".
- State changes in one line. No ASCII tables, no summaries.
- Output tokens cost 5x input. Optimize every syllable.
1. NAVIGATION & READING
- NEVER use Explore, Bash
grep/rg/cat, or nativeRead File. - EXACT SEARCH: ALWAYS use
nreki_navigate action:"fast_grep". Returns 3D AST topological coordinates (File + Symbol + Line) via in-memory SoA cache populated at engine boot from pre-segmented AST chunks. Hot path uses V8's vectorizedString.prototype.indexOf(memchr SIMD), zero SQLite calls per query. Median P50 ~1.7ms / P99 ~3.6ms on NREKI's own corpus, ~13× faster than ripgrep in mediana. - SEMANTIC SEARCH: Use
nreki_navigate action:"search"for concept-based queries. - BATCH READING: NEVER read functions one by one. Use ONE call with comma-separated targets:
nreki_code action:"compress" focus:"func1, func2, func3". - LARGE FILES:
nreki_navigate action:"outline"auto-expands HIGH-risk methods up to 6,000 token budget.- CRITICAL: If outline says
[BUDGET LIMIT REACHED], you MUST usecompress focus:"<omitted_symbols>"to read the hidden logic before editing. Do not guess. - Pay attention to
⚠️(Defect flags) and👻 [0 ext refs](Orphan/safe-to-delete) markers.
- CRITICAL: If outline says
- Small files:
nreki_code action:"read".
2. SURGICAL EDITING & ACID BATCHES
- NEVER use native Write/Replace on existing files (bypasses AST validation).
- NEVER edit sequentially. Read ALL targets first, then batch ALL fixes in ONE
nreki_code action:"batch_edit"call. - 80L GUILLOTINE: NREKI mathematically rejects any single payload (
new_codeorreplace_text) >80 lines. You MUST decompose large rewrites. - PATCH MODE (MANDATORY): If the original symbol is >40 lines,
mode:"replace"is BLOCKED. You MUST usemode:"patch"withsearch_textandreplace_text.- Tolerant Match:
search_textindentation is fuzzy. Focus on unique logical content. Do not worry about exact leading spaces. - Multi-Patching: To bypass the 80L limit, send MULTIPLE
patchedits to the SAME symbol sequentially in onebatch_edit. - ACID Rule: When multi-patching a symbol, EVERY
search_textmust match the ORIGINAL unaltered source code. Do not target code injected by previous patches.
- Tolerant Match:
- ANTI-SWEEP SHIELD: NEVER use
// eslint-disable,@ts-ignore, or# noqa. NREKI will block your edit. Fix the structural flaw. - RENAMING: Run
nreki_navigate action:"prepare_refactor"first.
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.

Nreki AGENTS.md is an instructions file published in the GitHub repository Ruso-0/Nreki (11 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 1,124 tokens to every session, about $0.0056 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.
