ljg-skills is a collection of custom Codex skills for tasks such as learning, writing, reading, relationship analysis, image creation, and investment analysis. Codex users install selected skills or the whole collection through a skills command-line interface. The catalogue entries are the collection's individual skills, plugin, and instruction.
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.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00221 | $0.03723 |
| Opus 5 | $0.00111 | $0.01861 |
| Sonnet 5 | $0.00044 | $0.00745 |
| Haiku 4.5 | $0.00022 | $0.00372 |
Grade A, and why
ljg-blind scanned grade A with 1 finding 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 12d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

盲区扫描
读你昨天跟 AI 的全部对话,照出那个你自己看不见的思维盲区,从微信读书点亮补它的一章。
盲区是什么
盲区不是知识缺口。不是"没读过某本书""不知道某个事实"——那种缺口,查一下就补上了。
盲区是一种结构性的思维习惯,它让某一类真相对你系统性地不可见。你不是想不到,是这个习惯让你压根没往那个方向看。它藏在你怎么想事情的方式里,不藏在你想的内容里。
所以证据不在"他说错了什么"。在——他没往哪看,他在哪绕了,他默认了什么却从没检。
五种盲区信号
从昨天的对话里找这五种。每一种都要落到具体的话上,不能凭感觉。
- 绕开点——一个难题他打开了,又飞快合上。证据:问题抛出,转头换话题,或一句"这个先不管"滑过去。
- 空转框架——反复换视角切同一个问题,没有一个落地。证据:一个问题被套上三四副框架,每副都浅尝辄止,最后没结论。
- 单一取景框——一整天只调用一两副 f(逢事就"约束""进化""博弈"),没试过别的镜子。这是他最隐蔽的盲区:越趁手的 f,越挡住别的 f 能照见的东西。(继刚看世界 = f(x),四轴是他默认的四副 f;正因为默认,才最该查他今天是不是又只用了其中一副。)
- 未检前提——一个默认假设贯穿全程,他当硬约束在用,从没问过它是不是假墙。证据:某个"本来就该这样"的说法,反复出现却从未被他自己质疑。
- 相邻空缺——从他问的东西反推,本该问、却没问的那个角落。不是凭空猜,是他自己的线索指向那儿。
选哪一个
从信号里挑 1 个作为今天的盲区。宁可一个说透,不要五个都点一遍——盲区的密度低于精度。判据三条:
- 杠杆——补上它,下一步打开的可能性最多。
- 真盲——是他自己看不见的,不是知道了在拖的。
- 对位 mission——贴 M0(找新取景框)/ M1(求本质)。盲区若正好挡在他的主线上,优先。读
${LIFEOS_DIR:-$HOME/.codex/LIFEOS}/USER/TELOS/PRINCIPAL_TELOS.md确认主线。
操作步骤
第一步 · 定日期
# 默认昨天;用户传了 YYYY-MM-DD 就用那天(macOS BSD date)
target=${1:-$(date -v-1d +%Y-%m-%d)}
第二步 · 捞当天的对话
会话文件在 $HOME/.codex/sessions/YYYY/MM/DD/*.jsonl。目录日期按本机时间记录 session 的开始日,行内 timestamp 是 UTC;因此同时扫目标日与前一日目录,再按本机日期过滤消息。只读取顶层 task 的 response_item / message / user / input_text,排除 session_meta.payload.source.subagent 存在的子 agent 会话,以及 harness 包装和本次调用自身:
target=<上一步的日期>
out=/tmp/ljg-blind-${target}.txt
: > "$out"
previous_dir=$(date -j -v-1d -f '%Y-%m-%d' "$target" '+%Y/%m/%d')
target_dir=$(date -j -f '%Y-%m-%d' "$target" '+%Y/%m/%d')
for day_dir in "$previous_dir" "$target_dir"; do
session_dir="$HOME/.codex/sessions/$day_dir"
[ -d "$session_dir" ] || continue
find "$session_dir" -type f -name '*.jsonl' -print0
done | while IFS= read -r -d '' session_file; do
# Codex 将子 agent 与顶层 task 放在同一日期目录;从 session_meta 排除它们。
if jq -e 'select(.type=="session_meta") |
(.payload.source | type == "object" and has("subagent"))' \
"$session_file" >/dev/null 2>&1; then
continue
fi
jq -r --arg target "$target" '
def local_epoch:
sub("\\.[0-9]+Z$"; "Z") | fromdateiso8601;
select(.type=="response_item"
and .payload.type=="message"
and .payload.role=="user")
| (.timestamp | local_epoch) as $epoch
| select(($epoch | strflocaltime("%Y-%m-%d")) == $target)
| ([.payload.content[]?
| select(.type=="input_text")
| .text] | join("\n")) as $text
| select($text | length > 0)
| select(($text | test("^(<recommended_plugins>|<environment_context>|<task-notification>)")) | not)
| select(($text | test("(?i)(ljg-blind|扫盲区)")) | not)
| "[" + ($epoch | strflocaltime("%H:%M")) + "] " + $text
' "$session_file" 2>/dev/null >> "$out"
done
wc -m "$out"
What ships with it
2 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.
- 12d ago First seen · 215 lines · 221 tokens per session scan A a24aaf806c8b
ljg-blind is a skill published in the GitHub repository lijigang/ljg-skills (7,340 stars, last pushed 3d ago), licensed MIT. It adds 221 tokens to every session and 3,723 once invoked, about $0.0011 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
