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.

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 | $0.00099 | $0.01065 |
| Opus 5.5 | $0.00040 | $0.00426 |
| Sonnet 5.5 | $0.00020 | $0.00213 |
| Haiku 4.5 | $0.00010 | $0.00106 |
Grade A, and why
gap-analysis 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 15d 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 — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Gap Analysis Protocol
EXTREMELY_IMPORTANT: This is a MANDATORY protocol, not a suggestion. Follow every step. Do not skip steps. Do not combine steps. Do not summarize. Work through each gate in order.
You have produced a design, plan, or recommendation. Before presenting it as final, you MUST run all 7 checks below. Do not skip any. Report each result explicitly.
If your harness supports subagents, dispatch these checks to a fresh-context reviewer
using agents/reasoning-reviewer.md — a reviewer that has not seen your design's
justifications catches what self-review misses. Required at the DEEP tier; recommended
whenever the decision is hard to reverse.
CHECK 1 — Inversion
Ask: "How would I guarantee this fails?"
List at least 3 specific failure modes; keep listing while distinct ones come to mind, stop when candidates turn contrived. For each, verify your solution prevents it. If any failure mode is not prevented, flag it as an open risk.
CHECK 2 — Second-order consequences
Ask: "And then what?" three times.
- 1st order: [the immediate intended effect]
- 2nd order: [the effect of that effect — often unintended]
- 3rd order: [the cascading consequence — often counterintuitive]
If 2nd or 3rd order effects are negative, state whether they're acceptable or require design changes.
CHECK 3 — MECE coverage
Ask: "Have I covered the entire problem space with no gaps and no overlaps?"
List the dimensions you've addressed. Identify any dimension you haven't addressed. Gaps are where surprises live.
CHECK 4 — Map vs territory
Ask: "Where does my model diverge from reality?"
List at least 3 things you simplified, assumed, or ignored — more if you know of them. For each, state the risk if reality differs from your model.
CHECK 5 — Adversarial
Ask: "How would a hostile actor exploit this? How would a careless user break this?"
Identify the weakest point. State whether it's acceptable or needs hardening.
CHECK 6 — Simplicity
Ask: "Is there a simpler solution I'm overlooking?"
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.

gap-analysis is a skill published in the GitHub repository xD4O/praxis (28 stars, last pushed 2mo ago), licensed MIT. It adds 99 tokens to every session and 1,065 once invoked, about $0.0004 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 2026-10-02.

autoreview
Structured code review through the shared OpenClaw agent-skills installation.
omh-code-review
This is an OMH code-review workflow skill, projected for Agent Skills hosts (Claude Code, Codex, Cursor, opencode, OpenClaw, pi).

Review the last Codex assistant message (plan, analysis, or proposal) with inline annotations in a TUI overlay. Extracts the most recent response from Codex rollout files and opens it in revdiff for review and annotation.

Guide the user through a quadrant walk that maps the unknowns of a task — open by listing the known knowns, then work through known unknowns, unknown knowns, and unknown unknowns one stage at a time, ending with a complete four-quadrant map in the user's hands. Use when a request is ambiguous or underspecified, the…
