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 | $0.02544 | $0.02544 |
| Opus 5.5 | $0.01018 | $0.01018 |
| Sonnet 5.5 | $0.00509 | $0.00509 |
| Haiku 4.5 | $0.00254 | $0.00254 |
Grade A, and why
agentmemory-codex-windows 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 today.
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.
How it starts
The opening of the file, as written. The whole thing — 181 lines — stays where its author put it; the contents beside it link to each section on GitHub.
agentmemory — Agent Instructions
This repository is the independent AgentMemory for Codex on Windows
downstream. Public downstream releases use
package.json#agentmemoryDownstream.version; the package version,
src/version.ts, export schema, and plugin versions stay aligned to the
upstream AgentMemory compatibility line. Do not publish any @agentmemory/*
package from this repository.
Architecture
agentmemory is a persistent memory system for AI coding agents, built on iii-engine's three primitives (Worker/Function/Trigger). Everything goes through registerFunction/registerTrigger/sdk.trigger() — never bypass iii-engine with standalone SQLite or in-process alternatives.
- Engine: iii-sdk (WebSocket to iii-engine on port 49134)
- State: iii-engine StateModule file-backed KV (
./data/state_store.dbis a directory of per-scope.binsnapshots, not a SQLite database). The managed downstream pins engine 0.22.1 with the documentedstate::flushpatch and requiresAGENTMEMORY_STATE_DURABILITY=file-flush-v1; see the packaging contract for process-crash qualification and its limits. - Build: TypeScript → ESM via tsdown, output to
dist/ - Test: vitest (
npm testexcludes integration tests)
Windows/Codex downstream profile
The portable upstream package behavior described below remains the default for
other hosts. The supported Windows/Codex build in
packaging/windows-codex/ adds the following host-specific operating settings:
- four managed Codex hooks (
SessionStart,UserPromptSubmit,Stop, andSessionEnd) capture normal main-agent user and final-assistant turns while excluding ambient UI, title/fork, and subagent traffic; - capability-scoped
local-qwenuses only a loopback OpenAI-compatible server for typed graph extraction; all other LLM features receive the noop provider, fallback providers remain disabled, and force-proxy prevents standalone writes; - durable writes and manual graph provenance are exact-project scoped;
legacy forget is irreversible and reconciles exact live graph provenance,
but does not reconcile every other derived reference;
exact-project
delete-empty/restore-emptyactions recover one proven empty, processed non-cursor observation in its canonical row; see the packaging contract; deliberate reads may use*, and the managed user-prompt hook performs a required current-project recall or validated same-conversation source reuse, widening to bounded history discovery when local originals are inadequate. Candidates, partial failure and source reuse do not prove semantic verification; missing historical evidence holds dependent decisions, not independent work; - Codex performs selective promotion through the official memory, lesson, and manual graph tools; provider-backed summary, consolidation, reflection, crystallization, and compression remain disabled while local Qwen may enrich the exact-project graph, a fair cursor-preserving deferred backlog drains bounded batches after Qwen readiness events, optionally requests conditional startup through the managed Windows LocalAI adapter, and retains a 15-minute recovery probe, and deterministic structural extraction stays available; and
- canonical data is installation state, not a generated build artifact. See
packaging/windows-codex/README.mdfor build, cutover, and retention rules.
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.

agentmemory-codex-windows AGENTS.md is an instructions file published in the GitHub repository M-T-D-N/agentmemory-codex-windows (2 stars, last pushed today), licensed Apache-2.0. It adds 2,544 tokens to every session, about $0.0102 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 2026-08-31.
