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 | $0.00076 | $0.00377 |
| Opus 5 | $0.00038 | $0.00188 |
| Sonnet 5 | $0.00015 | $0.00075 |
| Haiku 4.5 | $0.00008 | $0.00038 |
Grade A, and why
landmine 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 9d 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
/genesis:landmine — Capture a Gotcha
Append one entry to docs/registry/LANDMINES.md. Speed matters more than
polish — capture now, the next session benefits forever.
Steps
- Identify the trap. If given as an argument, use it. Otherwise take it from the immediate conversation context: what just cost time or surprised us? Only ask the user if genuinely ambiguous.
- Write the entry in the file's format:
- Bold one-line trap statement.
- Why it is this way, what breaks if you assume otherwise, and the rule (always/never do X). Cite the files involved.
- Append it. Do not edit or delete existing entries.
- Confirm in one line: the bold trap sentence as written.
If docs/registry/LANDMINES.md does not exist but the user clearly wants the
capture, create it from the plugin's templates/registry/LANDMINES.md (at
../../templates/registry/ from this skill's base directory) and register it
in FILES.md (G1).
Quality bar: a landmine entry must let a future reader avoid the trap without re-deriving it. "X is weird" fails the bar; "X inverts direction when lineId === 'green'; always go through getNextStation, never index arithmetic" passes it.
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.

landmine is a skill published in the GitHub repository godshiba/genesis (2 stars, last pushed 2mo ago), licensed MIT. It adds 76 tokens to every session and 377 once invoked, about $0.0004 per session on Opus 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 2026-08-31.

self-improve
Self-improve this skills repo — surface and (safely) apply quality improvements across four parallel read-only lenses (Clarity, Leanness, Coverage, Ergonomics). Sibling of /self-audit — audit fixes rule violations, improve raises quality where no rule is broken. Local meta-skill, independent of the /task: pipeline.
self-audit
Self-audit this skills repo against CLAUDE.md invariants, the artifact contract, and README/CLAUDE.md/docs sync via three parallel read-only subagents. Local meta-skill — independent of the /task: pipeline.
grill
Interrogate a plan or decision one question at a time before capture, keeping a decision-plus-rationale ledger, then route to the right capture skill.
architect
Answer build-or-adopt honestly, then design one committed architecture from your own understanding of the problem — driven by ranked quality attributes, stress-tested against the field and against change, proven by a walking skeleton, its consequences confirmed by the user, committed to ARCHITECTURE.md. A command the…
designer
Settle the look before the pixels — audience and context first, then the base and the delta, taste settled by looking at real states, accessibility as the floor, one design language committed to DESIGN.md as tokens with roles. A command the user types, for work with an interface someone will see; standalone, no other…

Per-repo configuration — pin the work-file directory, verify commands, and issue tracking, seed the project docs, and leave the pointer that tells every future session this project works this way.
