LazyCodex is an agent harness for working on complex codebases, combining project memory, planning, execution, and completion checks inside Codex. It is for developers who want structured, repeatable assistance when handling substantial software projects. The catalogue contains the skills, hook, and MCP integration that provide its workflow inside Codex.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00063 | $0.02742 |
| Opus 5.5 | $0.00025 | $0.01097 |
| Sonnet 5.5 | $0.00013 | $0.00548 |
| Haiku 4.5 | $0.00006 | $0.00274 |
Grade A, and why
coding-agent-sessions 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 17d 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.

The opening of the file, as written. The whole thing — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Coding Agent Sessions
Find local coding-agent sessions across agent products before answering from memory. Prefer the bundled finder for broad cross-platform search, then read the selected session or raw file when you need exact evidence.
PHASE 0 - PLATFORM ROUTER
-
IF the user names a platform, load its reference first.
Platform Read Codex / OpenAI Codex CLI references/codex.mdClaude Code / Claude Desktop histories references/claude.mdOMO / Senpi / pi coding-agent logs references/senpi.mdoh-my-pi ( omp,~/.omp) and gajae-code (gjc,~/.gjc) logsreferences/senpi.mdOpenCode / oh-my-openagent (formerly oh-my-opencode) storage references/opencode.mdOpenClaw, Droid, Amp, Gemini, Kimi, Qwen, Codebuff, Roo/Kilo/Cline, Kodu, Cursor CLI, Aider, Kiro, Goose, Hermes, Crush, Zed, Aside references/all-platforms.mdUnknown / "any session" / cross-agent search references/all-platforms.md -
Run the broad finder first unless the user gave an exact file path. For fuzzy recall, expand the query first.
When the user remembers a task vaguely ("that OpenCode bug", "the dashboard PR", "when did we fix X"), derive 3-6 short query lanes before searching: product/tool aliases, repo/package names, exact error text, issue/PR/session IDs, English/Korean phrasing, and likely verbs such as fix, review, plan, deploy, or merge. Run the lanes together with repeated --query so match_reasons shows which wording found the hit.

What ships with it
24 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.

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.

coding-agent-sessions is a skill published in the GitHub repository code-yeongyu/lazycodex (3,782 stars, last pushed 3d ago), licensed MIT. It adds 63 tokens to every session and 2,742 once invoked, about $0.0003 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 2026-08-30.

Work with Feishu or Lark bots, docs, sheets, bitables, approval flows, and OpenAPI/MCP setup without hardcoding credentials.
interview
Ask one useful structured question at a time only when material product/implementation choices are genuinely missing; remember answers and produce a brief/spec. Discoverable facts should be investigated instead of asked.
refocusing
Use when a long-running agent may have lost the product outcome, when context was compacted, when work has crossed a major boundary, or when a fresh path-based trace is needed before the next consequential action. Not for fresh-session orientation, waking an idle seat, or checkpoints.

Bring a published CLI from the public library into the internal library so it's identical to a freshly-generated copy — module path reverted, manuscripts placed alongside, ready for /printing-press-polish or /printing-press-emboss.
