Publisher description: Sno Station Skills: 31 tested skills that turn Claude Code and Codex into one working team. Cross-vendor peer review, automatic handoff when an agent hits its quota, a one-page morning brief, work orders with proof, and a nightly loop that learns from your own sessions. Open source, installed with one sno setup.
Catalogue scope: 50 procedural entries from 50 source paths.

- 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.
Self-containedActs undeclared1,146 words - 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.
Self-containedActs undeclared723 words - 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.
Self-containedActs undeclared2,064 words - 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.
Self-containedActs undeclared902 words - 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.
Self-containedActs undeclared795 words - 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.
Self-containedActs undeclared1,000 words - 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.
Self-containedActs undeclared1,006 words - python-coder
Implement and refactor production Python, FastAPI, Pydantic, async, and migrations.
Self-containedActs undeclared1,006 words - rust-coder
Implement, refactor, and migrate production Rust with repository-grounded ownership, type-driven invariants, explicit errors, safe concurrency, minimal unsafe code, and verified Cargo workflows. Use for Rust features, crates, CLIs, services, libraries, async code, FFI, performance work, migrations, or substantial .rs and Cargo.toml changes, including requests such as 'rust-coder', 'write Rust', or 'implement this Rust feature with Codex'.
Reaches the webActs undeclared436 words - shellscript-coder
Implement and refactor production shell scripts, command-line tools, automation, process wrappers, and Git or infrastructure helpers with reliable failures, useful logs, and machine-readable output.
Self-containedActs undeclared1,085 words - test-writer
Write and improve test-owned code: tests, test scripts, fixtures, evals, and test-only helpers. Use whenever Codex is asked to create or change test code. Its only job is to produce the strongest practical tests in the repository's existing harness, run them, and fix defects in the test code.
Self-containedActs undeclared817 words - ts-coder
Implement and refactor production TypeScript/TSX, strict types, APIs, and migrations.
Self-containedActs undeclared770 words - 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.
Self-containedActs undeclared5,652 words - 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.
Self-containedActs undeclared500 words - 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.
Self-containedActs undeclared564 words - 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.

Self-containedActs undeclared1,006 words - peer-review
Adversarial review and fix loop for code, specs, plans, and migration manifests.
Needs a keyActs undeclared4,943 words - test-writer
Write and improve test-owned code: tests, test scripts, fixtures, evals, and test-only helpers. Use whenever Codex is asked to create or change test code. Its only job is to produce the strongest practical tests in the repository's existing harness, run them, and fix defects in the test code.
Self-containedActs undeclared817 words - codex-coder
Route production coding tasks from Claude Code to the user-level Codex Shell, TypeScript, Python, or Rust workflow through a direct `codex exec` run. Use for "codex-coder", "ask Codex to write code", "generate with Codex", language migrations, or mixed Shell/TypeScript/Python/Rust implementation.
Needs a keyActs undeclared1,476 words - codex-coder
Route production coding tasks to the user-level Shell, TypeScript, Python, or Rust Codex workflow. Use for "codex-coder", "Codex write", "generate with Codex", language migrations, or mixed Shell/TypeScript/Python/Rust implementation when Codex should choose the correct language specialist automatically.
Self-containedActs undeclared623 words - 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 everything is healthy.
Self-containedActs undeclared552 words - python-coder
Implement and refactor production Python, FastAPI, Pydantic, async, and migrations.
Self-containedActs undeclared1,006 words - rust-coder
Implement, refactor, and migrate production Rust with repository-grounded ownership, type-driven invariants, explicit errors, safe concurrency, minimal unsafe code, and verified Cargo workflows. Use for Rust features, crates, CLIs, services, libraries, async code, FFI, performance work, migrations, or substantial .rs and Cargo.toml changes, including requests such as 'rust-coder', 'write Rust', or 'implement this Rust feature with Codex'.
Reaches the webActs undeclared436 words - shellscript-coder
Implement and refactor production shell scripts, command-line tools, automation, process wrappers, and Git or infrastructure helpers with reliable failures, useful logs, and machine-readable output.
Self-containedActs undeclared1,085 words - 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", or "sno skills". The exact flags always come from the installed binary, never from this file. Do not use it to decide the owner's choices for them.
Self-containedActs undeclared1,188 words - ts-coder
Implement and refactor production TypeScript/TSX, strict types, APIs, and migrations.
Self-containedActs undeclared770 words - rem-reflect
Self Learning from this machine's Claude Code, Codex, Hermes, OpenClaw and Cursor sessions. Decide skill changes and lessons with accept/reject/tbd; recall lessons at session start.
Self-containedActs undeclared2,104 words - 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.
Self-containedActs undeclared2,363 words - 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.
Self-containedActs undeclared2,014 words - 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`.
Self-containedActs undeclared415 words - 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.
Self-containedActs undeclared1,600 words - rotate-agent
Quota-triggered failover from Claude Code, Codex, Cursor, Hermes or OpenClaw. When armed, it reads the sender quota and tries other-vendor models in place, then receiving agents in the configured order. Use when a long run must finish even if one vendor's quota runs out. Not a monitor for anything else.
Needs a keyActs undeclared1,571 words - 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.
Self-containedActs undeclared1,275 words - 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.
Self-containedActs undeclared723 words - cos
MANUAL-ONLY: load solely when the human owner types `/cos`, uses `$cos`, or asks you to act as the Chief of Staff (COS). The COS is the one agent the owner talks to; it coordinates the owner and the per-project Project Leads (PLs). A task card, charter, or dispatch makes you an executor, not COS.
Self-containedActs undeclared12,593 words - cos-evolve
Turn repeated management failures into enforced COS or PL rules. Load ONLY after the owner has explicitly activated the cos role for this session and the COS core routes here. Never invoke directly.
Self-containedActs undeclared2,645 words - cos-review
Review PL self-approvals, estimates, board drift, and close quality after a declared night shift. Loaded ONLY by the cos core via its routing table; NEVER auto-load from context or invoke directly.
Self-containedActs undeclared2,049 words - cos-watch
Supervise active PLs, including wake cadence, liveness, recovery, large-run launches, and cross-journey order. Loaded ONLY by the cos core via its routing table; NEVER auto-load from context or invoke directly.
Self-containedActs undeclared2,063 words - deliver
Carry out a released charter to a proven result: plan only as much as the work needs, do the work through the project's own workers, prove every success check with a recorded real run, get one independent review, and close honestly. Invoke explicitly as `$deliver <charter>` (Codex) or `/deliver <charter>` (Claude, Cursor), or the way your agent invokes a skill, or when a dispatch names you the executor of a charter.
Self-containedActs undeclared862 words - pl
MANUAL-ONLY — load solely when the human owner types `/pl`, uses `$pl`, or asks you to act as the Project Lead (PL). Supervise one project lane and its executor agents. A charter or dispatch means: you are an EXECUTOR, not the PL.
Needs a keyActs undeclared9,764 words - 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.
Self-containedActs undeclared906 words - 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.
Self-containedActs undeclared2,187 words - 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.
Self-containedActs undeclared4,865 words - 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.
Self-containedActs undeclared1,009 words - pl-watch
PL (Project Lead) role sub-skill for supervising in-flight executors. Loaded ONLY through the pl core routing table; NEVER auto-load from context, never invoke directly.
