Skills can run code on your machine — read the SKILL.md first.
What it does
In the author's own words, from each skill's SKILL.md — showing the first 30 of 31 files.
-
agentic-time-estimate
Answer how long agent work will take, how much longer active work needs, or what clock time applies. Estimate full AI-agent wall time, measure active progress first, and get owner-facing times from `sno report-time`. Never estimate human-developer time.
skills/H-reporting-and-visibility/agentic-time-estimate/skill/SKILL.md on GitHub (opens in a new tab) -
away-brief
Give the owner one page when they come back from sleep, a meeting or a long run: what got done, what is stuck, what waits for their answer, and what it cost in quota. Use when the owner asks what happened while they were away, wants a status page, or when you finish a long stretch of work and must report it.
skills/H-reporting-and-visibility/away-brief/skill/SKILL.md on GitHub (opens in a new tab) -
catch-report
Report how many problems the two brains found: mutual review (the other model checks the work, from the peer-review records) and self-check (an agent finds its own error in its own conversation, judged by that agent's own model), side by side. Use when the owner asks whether the second agent or the reviews are worth it, or wants the week's review results.
skills/H-reporting-and-visibility/catch-report/skill/SKILL.md on GitHub (opens in a new tab) -
agentic-walkthrough
Prove that a reported run caused its intended real effect. Walk the executor path from entry to effect, capture one observable per hop, and report a result a no-op could not produce.
skills/J-peer-review-and-audit/agentic-walkthrough/skill/SKILL.md on GitHub (opens in a new tab) -
first-principles-review
MANUAL-ONLY: challenge a product idea, design, PRD, or architecture from first principles. Use only when the user names this skill. Research first, then write a local review and PRD handoff.
skills/J-peer-review-and-audit/first-principles-review/skill/SKILL.md on GitHub (opens in a new tab) -
less-is-more
Write the least code that works, and cut what an AI agent over-built. Use on any coding task: write, fix, refactor, or review a diff. Also when the user says 'less', 'simplify', 'too complex', 'over-engineered', or 'what can we delete'. Not for prose, research, or non-code questions.
skills/J-peer-review-and-audit/less-is-more/skill/SKILL.md on GitHub (opens in a new tab) -
owner-intent-audit
Check agent-produced plans, tests, or code against the owner's actual intent. Find missing meaning, unrequested work, stale truth, unreachable decisions, unsupported completion claims, and implementation debt. Use before approval or merge.
skills/J-peer-review-and-audit/owner-intent-audit/skill/SKILL.md on GitHub (opens in a new tab) -
peer-review
Adversarial review and fix loop for code, specs, plans, and migration manifests.
skills/J-peer-review-and-audit/peer-review/skill/SKILL.md on GitHub (opens in a new tab) -
medic
Check that this machine's agent team can work and say what is wrong in plain lines: tools installed, core skills installed, skill commands runnable, hooks configured, Reach seat live, a heartbeat running, both vendors' quota readable, temp space free. Checks only, never repairs. Use on a new machine, when agents stop reaching each other or a long run fails to start, or when the owner asks whether…
skills/M-build-and-rollout/medic/skill/SKILL.md on GitHub (opens in a new tab) -
sno-cli
Operate the `sno` command-line tool: install, update, check, and uninstall Sno products, read the exact commands and flags of the installed version, and run the account, skills, onboarding, Station telemetry and REM commands. Use when the owner or a task says "sno", "Sno CLI", "sno setup", "sno update", "sno doctor", "sno uninstall", "sno station", "telemetry consent", "rem verdict", "sno account…
skills/M-build-and-rollout/sno-cli/skill/SKILL.md on GitHub (opens in a new tab) -
rem-reflect
The local experience loop: once a day, turn this machine's own Claude Code and Codex sessions into human-gated skill changes and lessons. Run, review with accept/reject/tbd, recall at session start.
skills/R-recursive-self-improvement/rem-reflect/skill/SKILL.md on GitHub (opens in a new tab) -
handoff
Transfer full task ownership to a fresh agent with a verified brief and explicit release. Use for replacing the current executor, including a directly assigned task with no work card; not for supervising a helper.
skills/S-communication-and-handoff/handoff/skill/SKILL.md on GitHub (opens in a new tab) -
heartbeat
Set recurring checks or completion watches with `sno heartbeat` and its persistent log reader. Use for periodic reports or unattended long runs. Not for calendar scheduling or commands watched directly.
skills/S-communication-and-handoff/heartbeat/skill/SKILL.md on GitHub (opens in a new tab) -
join-talk
Register this agent and terminal with Reach for cards, calls and wake-ups. Use when asked to join, connect, or become reachable, or when a manually opened agent lacks `SNO_EXECUTOR_ADDR`.
skills/S-communication-and-handoff/join-talk/skill/SKILL.md on GitHub (opens in a new tab) -
reach
Contact another agent, exchange work cards, inspect replies, or manage reachable seats through the installed Reach program. Use for communication; full task ownership transfer belongs to handoff.
skills/S-communication-and-handoff/reach/skill/SKILL.md on GitHub (opens in a new tab) -
rotate-agent
Quota-triggered failover between agent harness vendors, either direction. When asked to arm it, it starts a watch (optionally time-limited) that reads the working vendor's remaining subscription every few minutes; below a threshold, and only while the sender is still alive, it orders a handoff to a receiver from the other vendor, once. Use when a long run must finish even if one vendor's quota ru…
skills/S-communication-and-handoff/rotate-agent/skill/SKILL.md on GitHub (opens in a new tab) -
subscription-quota-check
Read remaining Claude Code and Codex subscription quota without spending it. Use when the user asks or after a vendor rejects work for quota; a caller such as rotate-agent may also arm a scheduled read on purpose. Never poll on your own; after a `wait` verdict, pass the reset wait to `sno heartbeat` and re-read once when it ends.
skills/S-communication-and-handoff/subscription-quota-check/skill/SKILL.md on GitHub (opens in a new tab) -
charter
Write, revise or review a charter: the one document that tells an executor what to deliver, what is out of bounds, what the owner already decided, and how each success check will be proven. Use when work needs a written brief before someone else does it, or when asked to write, change or check a charter.
skills/T-delegation-and-work-orders/charter/skill/SKILL.md on GitHub (opens in a new tab) -
deliver
Carry out a released charter to a proven result: plan only as much as the work needs, do the work through the project's own workers, prove every success check with a recorded real run, get one independent review, and close honestly. Invoke explicitly as `$deliver <charter>` (Codex) or `/deliver <charter>` (Claude), or the way your agent invokes a skill, or when a dispatch names you the executor o…

e2e-environment-preflight
Check external services, hosts, browser sessions, model endpoints, and agents before an end-to-end run. MANUAL-ONLY: load when a caller names it. NEVER auto-load from context for ordinary testing or debugging.
skills/J-peer-review-and-audit/e2e/skills/e2e-environment-preflight/SKILL.md on GitHub (opens in a new tab) -
e2e-red-triage
Classify one unexpected end-to-end test failure as a product defect or an environment fault needing a new preflight check. MANUAL-ONLY: load when the suite runner names a specific failure. NEVER auto-load from context.
skills/J-peer-review-and-audit/e2e/skills/e2e-red-triage/SKILL.md on GitHub (opens in a new tab) -
cos-evolve
Turn repeated management failures into enforced COS or PL rules. Load ONLY after the owner has explicitly activated the cos role for this session and the COS core routes here. Never invoke directly.
skills/T-delegation-and-work-orders/cos/skills/cos-evolve/SKILL.md on GitHub (opens in a new tab) -
cos-review
Review PL self-approvals, estimates, board drift, and close quality after a declared night shift. Loaded ONLY by the cos core via its routing table; NEVER auto-load from context or invoke directly.
skills/T-delegation-and-work-orders/cos/skills/cos-review/SKILL.md on GitHub (opens in a new tab) -
cos-watch
Supervise active PLs, including wake cadence, liveness, recovery, large-run launches, and cross-journey order. Loaded ONLY by the cos core via its routing table; NEVER auto-load from context or invoke directly.
skills/T-delegation-and-work-orders/cos/skills/cos-watch/SKILL.md on GitHub (opens in a new tab) -
cos
MANUAL-ONLY: load solely when the human owner types `/cos`, uses `$cos`, or asks you to act as the Chief of Staff (COS). The COS is the one agent the owner talks to; it coordinates the owner and the per-project Project Leads (PLs). A task card, charter, or dispatch makes you an executor, not COS.
skills/T-delegation-and-work-orders/cos/skills/cos/SKILL.md on GitHub (opens in a new tab) -
pl-analyze
PL (Project Lead) role sub-skill for incident analysis and process evaluation. Loaded through the pl core routing table, or when the owner explicitly asks for a retrospective or root-cause write-up; NEVER auto-load from ambient context.
skills/T-delegation-and-work-orders/pl/skills/pl-analyze/SKILL.md on GitHub (opens in a new tab) -
pl-audit
PL (Project Lead) role sub-skill for acceptance and close-audit. Loaded ONLY through the pl core routing table; NEVER auto-load from context, never invoke directly.

pl-dispatch
PL (Project Lead) role sub-skill for opening and scheduling journeys. Loaded ONLY through the pl core routing table; NEVER auto-load from context, never invoke directly.
skills/T-delegation-and-work-orders/pl/skills/pl-dispatch/SKILL.md on GitHub (opens in a new tab) -
pl-env
PL role sub-skill — environment doctoring. Loaded ONLY by the pl core via its routing table; NEVER auto-load from context, never invoke directly.

Review before you install
A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
