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 | $0.00026 | $0.01494 |
| Opus 5.5 | $0.00010 | $0.00598 |
| Sonnet 5.5 | $0.00005 | $0.00299 |
| Haiku 4.5 | $0.00003 | $0.00149 |
Grade A, and why
nhk-upkeep 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 1mo 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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
NHK Upkeep
Use this skill only after the NHK foundation exists. It reconciles NHK-owned rules with the currently installed references and repairs active project descriptions; it does not bootstrap missing surfaces or perform an archive transition.
Router Handoff
Reuse a welcome-to-nhk handoff only when it is for the current workspace and current NHK run, and its Route selects this skill. If the handoff is absent, unresolved, or stale, run welcome-to-nhk first. If it selects another route, hand off and do not continue upkeep.
Use the handoff's dependency, instruction, topology, and complete-foundation state as the maintenance input. Do not persist the handoff or repeat the topology decision inside upkeep.
Maintenance Pass
On every upkeep run, compare NHK-owned rules against the currently installed reference contracts, even when workspace documents look complete and project facts have not changed. Read the matching canonical instruction template, all five companion templates, and the archive-index template through the paths below, plus the agent-definition template only when NHK agent definitions exist. Reuse applicable content already read in this context only when it is unchanged. This comparison uses the installed bundle; upkeep does not fetch or install NHK updates.
- Compare the canonical instruction and thin adapter, if present, against the live workspace and the matching
../references/AGENTS-template.mdor../references/CLAUDE-template.md; keep the canonical topology and applicable line budget. - Compare the single Task Routing table in
coding-agent-guide.mdagainst current routes and../references/coding-agent-guide-template.md; keep it at or below 80 lines. - Compare
implementation-planning.mdagainst../references/implementation-planning-template.md; keep its Superpowers-compatible task contract and 80-line limit. - Compare
worker-policy.mdagainst../references/worker-policy-template.md; reconcile dispatch, review, and tier permissions within 100 lines, following its legacy tier migration. - Compare
execution-recovery.mdagainst../references/execution-recovery-template.md; reconcile diagnosis, recovery, and stop rules within 80 lines. - Compare
documentation-governance.mdagainst actual document roles and../references/documentation-governance-template.md; keep it at or below 100 lines. - Compare
archive/README.mdagainst existing archived workstreams and../references/archive-readme-template.md; keep every index entry resolvable. - When
.claude/agents/nhk-*.mddefinitions exist, compare them against../references/claude-agents-template.mdand reconcile their frontmatter and shared body. Create any missing current definition in that set and report each retired definition the template names for the human to delete. An absent set stays absent; the human declined or was never offered it. - Inspect existing implementation plans, task lists,
task_plan.md,progress.md, andfindings.mdas active surfaces, not permanent assumptions. - Repair inaccurate active references and status descriptions, replace any Claude companion
@import with a literal on-demand path, then verify cross-links and instruction structure.
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.

nhk-upkeep is a skill published in the GitHub repository Rainnystone/naive-harness-kit (21 stars, last pushed 18d ago), licensed MIT. It adds 26 tokens to every session and 1,494 once invoked, about $0.0001 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.
Other skills, from other repositories
merge-review
Reviews pending fleet worktree merges before they're accepted. Reads the merge-check queue, detects file-level conflicts between branches, proposes a safe merge order, and surfaces reconciliation plans for overlapping changes.
workspace
Multi-repo campaign coordinator. Same lifecycle as fleet -- scope claims, discovery relay, wave-based execution -- but the unit of work is a repo, not a file. Coordinates campaigns across repositories with shared context.
decision-map
Turn a loose idea into a git-tracked, session-resumable map of typed investigation tickets, then drive them to resolution one at a time. The planning-loop engine for work that is still being figured out — too fuzzy for a campaign, too big for a single intake item. Resolved tickets graduate into .planning/intake/ for…
unharness
Safely leave Citadel using the active adoption receipt. Produces a no-write, reviewable plan, preserves a portable archive, removes only exact owned material, and reports modified or externally registered surfaces as retained or unknown. Legacy installs must be imported before exact leave is claimed.
review
Get a person's review of an artifact you produced or were handed: a plan, spec, report or other Markdown file. Use when you have a file that someone should read and react to before work continues, or when the user asks to send something for review. Picks the Terminal (TUI) or the Web from this project's recorded…

First-officer status query/mutate/display surface — the status command flag docs, --set field docs, canonical captain-facing invocations, the Captain-Facing State Display rendering, and the GitHub-issue-filing approval gate. Invoke at the first ad-hoc status question, --set mutation, --next-id/--resolve lookup, or…
