h5i-ctx2img: Instructions file for Codex

AGENTS.md

h5i-ctx2img AGENTS.md is an instructions file for Codex, OpenCode from Koukyosyumei/h5i-ctx2img. It costs 1,313 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for h5i, a system that gives coding agents shared memory and records their work. They define how the agent should load project guidance, recall context, and record code commits.

In plain words
What is it for?
Use them when working in the Koukyosyumei/h5i-ctx2img repository, especially for session setup, shared context, commits, and large command output.
Why use it?
They reduce lost context between sessions and make the agent’s coding work easier to trace. They also standardize how the agent starts and documents tasks.

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

This is Koukyosyumei/h5i-ctx2img's own configuration. It tells Codex and OpenCode how to work on h5i-ctx2img 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 h5i-ctx2img 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

h5i-ctx2img 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 11d 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.

How it starts

The opening of the file, as written. The whole thing — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Persona

At the start of a session, read PERSONA.md at the repo root (if present) and follow it as your standing working style. Do not read other files under the profile's persona source directory — PERSONA.md is the resolved, per-env brief.

h5i Integration

This repository uses h5i — auditable workspaces for AI coding agents.

Codex should use h5i recall context as shared cross-session memory and h5i capture commit to record AI provenance on code commits.

Workflow

At the start of a non-trivial task, check the current goal/pin, then (re)set it:

h5i recall context goal        # prints the goal + warns if context is PINNED to a stale branch
h5i recall context init --goal "<one-line task summary>"

Run init even if a workspace already exists — it is idempotent and just updates the goal in place (keeping the context branch and milestones). A session often resumes with a stale goal from a previous task; always re-point it at what you are doing now instead of skipping init because a workspace exists. If context goal reports the context is pinned to a branch other than the current git branch, run h5i recall context unpin to resume branch tracking.

While working:

h5i hook codex sync           # after a burst of reads/edits — auto-traces OBSERVE/ACT and mines THINK/NOTE from your transcript

You do not need to emit OBSERVE / THINK / ACT trace entries by hand — h5i hook codex sync (and h5i hook codex finish) derives them from the Codex session JSONL. The only trace you should write directly is an explicit flag a reviewer must see immediately:

h5i recall context trace --kind NOTE "TODO: … / LIMITATION: … / RISK: …"

After a logical milestone:

h5i hook codex finish --summary "<milestone summary>"

Code commits

git add <exact paths>
h5i capture commit -m "…" --agent codex

When h5i hook setup --write --target codex has installed the Stop hook, h5i hook codex finish records the raw human prompt from the Codex session JSONL. --intent remains a fallback for CI/scripts/manual commits where no Codex session sync runs.

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.
