codex-progress-journal

codex-progress-journal is a skill for Claude Code, Codex from YankielDBC2/codex-skills-library. It costs 31 tokens per session (303 once invoked), scanned A, original, MIT.

A note-taking system for keeping the state, plans, decisions, and handoff details of long-running coding work understandable.

In plain words
What is it for?
It helps maintain progress journals, implementation plans, decision records, project maps, assumptions, changed-file notes, and safe next steps.
Why use it?
Large tasks can span sessions, agents, and many decisions, making it easy to lose track of what was tried or what remains. The system keeps durable notes aligned with the actual project.

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

codex-progress-journal 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 3d 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.

What it actually says

Codex Progress Journal

Goal

Keep long-running agent work understandable and resumable.

When to use

Use when work spans multiple sessions, multiple agents, large refactors, uncertain plans, or important decisions.

When not to use

Do not use for tiny one-shot tasks where notes would add noise.

Inputs

Inspect existing CODEX_STATE.md, PLANS.md, DECISIONS.md, issue notes, and recent changed files.

Workflow

  1. Capture the current objective.
  2. Record assumptions and constraints.
  3. Track files touched and why.
  4. Record decisions that should survive the session.
  5. Keep plans short and update them as reality changes.
  6. Mark completed, blocked, and deferred work.
  7. Remove stale notes when they become misleading.

Journal files

  • CODEX_STATE.md: current state and next action.
  • PLANS.md: active and proposed implementation plans.
  • DECISIONS.md: durable decisions and rationale.
  • PROJECT_INDEX.md: repo map and commands.

Validation

Verify notes match the actual repository state before finalizing.

Final response

Summarize what changed in notes, current status, and next safe action.

Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
