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 | $0.00062 | $0.00439 |
| Opus 5 | $0.00031 | $0.00219 |
| Sonnet 5 | $0.00012 | $0.00088 |
| Haiku 4.5 | $0.00006 | $0.00044 |
Grade A, and why
klimkit-checklister 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
Klimkit Checklister
Use this before implementation work. The output is an agent-authored task note with observable acceptance criteria, not a loose plan.
Workflow
- Read the user request, repo instructions (
AGENTS.md), relevantdocs/work/LOGs, relevant docs, and enough nearby code to understand the real acceptance surface. - Resolve the active work folder. If the repo has no
docs/work/layout, useklimkit-setupfirst. - Create or update
docs/work/<NNN-DDMMYY-slug>/<phase>/NNN-acceptance-checklist.mdinside the current work folder's active phase. - Add an
Acceptance Checklistsection using checkbox bullets. - Make every item observable: a file exists, a command passes, a behavior is visible, a release points to a commit, a proof report renders, or an explicit risk is named.
- Include scope boundaries and skipped work. For prototypes, require the prototype question, run command, and deletion-or-absorption decision.
- Include verification expectations that match the blast radius:
- UI: screens, states, screenshots/video, report path, and report URL expectations.
- Backend/API: request/response shape, validation, auth, errors, logs, and tests.
- Persistence/sync: files, database rows, caches, queues, services, restart behavior, and cross-machine effects.
- Security-sensitive work: require
klimkit-security-auditor.
- Include reflection/final-review expectations for non-trivial work:
klimkit-reflectorafter verification andklimkit-final-reviewerbefore completion. - End with the checklist path and any unresolved scope questions.
Treat checklist items as blocking unless the user explicitly changes scope.
What ships with it
1 file 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.

klimkit-checklister is a skill published in the GitHub repository klimentij/klimkit (7 stars, last pushed 29d ago), licensed MIT. It adds 62 tokens to every session and 439 once invoked, about $0.0003 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.
