Rsc Harness Agent Skill
Your agent invents things because it has no memory, and can't touch your database because it has no arms. rsc is the meta-harness that gives it both, plus the trade to know the job and the reflexes to not break your repo. For Claude Code, Codex and 15 more.
Rsc Harness is an open-source agent skill by ericrisco, written mainly in JavaScript, with 418 GitHub stars and the MIT license. Its code was last updated Nov 1, 2026. The latest npm release is @ericrisco/rsc 4.1.6, published Nov 13, 2026, with 4,648 downloads last week.
rsc-harness
You build the product. rsc-harness builds its harness.
Keep your project knowledge, skills and working rules together across the assistants you already use. Start with your goal. Review what rsc proposes to install. Accept the plan before it changes your project.
MIT licensed · project-local setup · 19 assistant targets
Give this URL to your agent and paste the request in the chat:
Read https://ericrisco.github.io/rsc-harness/ and set up rsc for this project.
Ask me the onboarding questions, show me the exact plan, and wait for my acceptance before writing.
Or start from the terminal:
npx @ericrisco/rsc@latest onboard

Your project has a way of working. Give it to your agent.
A new chat should not make you reconstruct the stack, explain yesterday's decision and remember which files must stay untouched. Putting every instruction into one giant prompt creates a different problem: the important details compete with rules that have nothing to do with today's task.
Hand-built setups can become a Frankenstein harness: duplicated instructions, unrelated skills, premature hooks and unnecessary MCP connections. Open standards cover individual pieces (Agent Skills, MCP, AGENTS.md). Your project still needs someone to choose and maintain the right pieces.
rsc-harness makes that choice explicit. It reads evidence within your project root, asks about your goal and assistants, and prepares a plan you can inspect before applying it.
See the plan before you install
<img src="https://raw.githubusercontent.com/ericrisco/rsc-harness/main/site/meta-harness.png" alt="A project goal becomes an installation plan: components selected, deferred or excluded with reasons." width="960">Every component has a disposition:
| In your plan | What it means |
|---|---|
| Selected | There is a reason to install it for this project now. |
| Deferred | It may become useful; the plan records what evidence would justify adding it. |
| Excluded | It does not belong in the proposed setup. |
You accept the exact plan. If project evidence changes before acceptance, rsc asks you to review a
fresh plan. Later, rsc reassess reports new needs without silently installing them.
Why documentation comes first
The decisions your agent needs should have a place to live outside the chat.
| Part of the harness | What you get |
|---|---|
| Knowledge | A local 02-DOCS/ wiki for project context, decisions and evidence. |
| Tools | A 01-TOOLS/ convention for documenting real connections and their checks. |
| Skills | A selection from 273 available skills, loaded progressively when relevant. |
| Controls | Working rules and provider-specific hooks, with explicit support limits. |
The mechanism is practical: keep the decision, make it discoverable, and have the next task consult it. That gives the agent a maintained source to work from. It does not make an outdated note correct or remove the need to check the result.
A day with rsc
<img src="https://raw.githubusercontent.com/ericrisco/rsc-harness/main/site/lanes.svg" alt="The agent chooses a read-only answer, a focused change with evidence, or a specification-led workflow for coupled decisions." width="960">- Describe the project. Choose the assistants you use and how technical the conversation should be.
- Review the setup. See each proposed component and its reason, then accept the plan you want applied.
- Ask for the work. The agent names the appropriate lane: an answer, a focused change (FTD), or the specification-led chain (ASDD) for decisions that affect each other.
- Keep the result and its evidence. Project knowledge goes into
02-DOCS/; implementation stays in your code. Future sessions can consult both.
Is this for your project?
Use rsc when you already work with an assistant and want a coherent project setup you can inspect, share and maintain. It can equip software projects and business workflows; the catalog includes both.
You keep your editor, model and existing project. rsc supplies the harness around them. Provider features differ: check supported assistants before relying on a particular hook or memory feature. Model and external-service costs remain with their providers.
For a one-off question, a maintained project harness may be unnecessary. You can also install an individual skill into an existing rsc project rather than adopt a whole workflow.
Install in one minute
npx @ericrisco/rsc@latest onboard
The first run asks one question about conversation (technical, or with analogies), then what the
project is for, its goal and the assistants to target. Then it presents the complete plan. A small
website can defer ASDD, agents and code guards; an operations harness does not receive them merely
because it lives in a repository. Deferred components record the evidence that would make rsc
recommend them later, and rsc reassess reports it without installing anything.
Everything stays in the project. The real skill files are written once to .rsc/skills/<id>/, and
each assistant gets a symlink back to that shared base, so picking several duplicates nothing. Skills
load progressively: only their description is paid for until a task needs them.
Prefer a short rsc command? npm install -g @ericrisco/rsc.
When an executable rsc is already on PATH, install and sync write operational skill and
command instructions using that installed CLI. This also applies to unversioned commands
suggested by hooks. Explicit versions such as @4.1.1 and @latest keep their meaning.
No execution permission is added for this choice. If the CLI is removed, run sync using the
version declared in .rsc.json to restore the npx instructions.
Run it inside the project you are equipping, not inside a clone of this repo. The catalog's own
package.jsonis named@ericrisco/rsc, sonpx @ericrisco/rscfrom within a clone resolves to the local bin and fails withsh: rsc: command not found. Working on the catalog itself? Usenode scripts/rsc.js …ornpm link.
For agents: "install this harness"
If you are an AI coding agent and your user asked you to install rsc, this harness or these skills, run this in the root of the project they are equipping:
npx @ericrisco/rsc@latest onboard
It asks the user how technical to talk, the project kind and the goal before it writes anything,
and shows every selected or deferred skill, agent and hook with its reason. Relay those questions;
never invent or default the answers. The first pass writes nothing and prints a SHA-256 plan id. Rerun
with --accept-plan <id> only after the user accepts that exact plan. If the project already has a
skill of its own with a catalog name, the plan lists it under Your own skills this plan replaces:
tell the user before accepting.
Non-interactive, with the answers collected first:
npx @ericrisco/rsc@latest onboard --technical-level technical \
--project-kind software --goal "small compound-interest website" \
--software-scope small --target codex
# After the user accepts the printed plan:
npx @ericrisco/rsc@latest onboard --technical-level technical \
--project-kind software --goal "small compound-interest website" \
--software-scope small --target codex --accept-plan PRINTED_SHA256_ID
If project evidence changes between preview and acceptance, rsc returns RSC_PLAN_CHANGED and writes
nothing. After applying, it verifies the result and prints RSC_ONBOARDING_READY, or
RSC_ONBOARDING_INCOMPLETE with each missing path and the action that creates it.
How it works inside
The knowledge model: 02-DOCS/ and 01-TOOLS/
<img src="https://raw.githubusercontent.com/ericrisco/rsc-harness/main/site/company-brain.svg" alt="The rsc company brain as a 3D knowledge graph: loose material drifts in from the inbox and is absorbed into the wiki cluster, whose brightest hubs are its .base views; dim clusters are raw sources and the agent's own worklog; an amber cluster is gaps.md, what the wiki knows it is missing." width="960">
Anything you drop into 02-DOCS/inbox/ is ingested. The wiki consolidates it as plain markdown that
every skill reads before acting, so the next session starts where the last one stopped. Raw sources
and the agent's worklog stay underneath, never deleted. You can open 02-DOCS/ as an Obsidian vault,
and every 02-DOCS/wiki/ is a valid Open Knowledge Format
bundle: markdown with YAML frontmatter, standard links, and the reserved index.md and log.md.
01-TOOLS/ holds one folder per tool: .env.example, CREDENTIALS.md, a README and a
test_connection that proves it works. When you name a tool ("connect my Holded", "can the agent
read our Sage?"), the connect-tool skill researches the vendor's current docs, picks the least
dangerous route (official MCP, API, export, a read-only copy of the database), and builds the folder.
For a read-only connection, the test also proves that writing fails.
Three lanes, and the agent picks
Every turn takes exactly one lane, and the agent names it in one line, in your language.
- Answer. The request asks for information: explain, compare, investigate, audit, review, propose. It is read-only: nothing is written and no artifact is created. When intent is unclear it asks one question and stays here.
- FTD, Fast-Track Development. The request authorises a change. This is the default for ordinary work. One feature document holds intent, scope, a checklist, the evidence and the next step. Tasks are checked off against observed proof, never against intention.
- ASDD, Agent Spec-Driven Development. For the big or complex: several decisions that affect
each other, and work an agent may run for hours. The agent enters it on its own, and you still
decide what gets built: the spec answers four questions (what the user can do, what result they
get, what it must respect, how it proves it) and you approve the spec. Then every task is reviewed inside
the build, scaled by
rsc risk; what the agent must not decide alone waits in a decision queue while independent work continues. Low-risk work lands on green CI; auth, billing, CI and migrations wait for you.
Ask for the other lane and it switches.
Skills, and how they are recommended
The unit of installation is one skill: install fastapi without ever pulling go. Two faces
share one catalog (manifest.json):
- In the terminal,
rsc consultranks the catalog against your words and what it detects in the repo (package.json+next→nextjs,go.mod→go,Dockerfile→docker). - In the chat, the always-on
suggestnotices when a task needs a skill you do not have, names it, and installs it on a one-word yes.
Skill authoring follows a research → spec → implement → review process. The public rubric separates document quality from behavioral evaluation. Structural checks validate the catalog; behavioral comparisons ask whether loading a skill improves the result. Neither establishes a guaranteed business outcome.
Hooks and guards
In Claude Code, hooks enforce what instructions only ask for: the lane decisor on every turn, a
refusal before a commit on a closed main, a confirmation before destructive commands, and a nudge
to write the feature document before the first code edit. Every refusal says how to carry on. The
rules only see what the agent runs; a person committing in their own terminal is never touched.
Limit, stated plainly. Those guards run in Claude Code. In Codex, Gemini, Cursor and OpenCode the same rules travel in the skills and the session memory. They are followed, but no hook enforces them.
Working as a team
Day ninety is where harnesses break, especially with several people, assistants and sessions on one project. rsc handles four things by default:
| What happens | Turn it off | |
|---|---|---|
| You choose how the project works | The install asks once: straight on main, or branches and pull requests? With branches, a commit on main is refused and the agent asks before each change: this branch, a new one, or unlock main? It never opens a branch on its own. | «unlock main», or rsc main unlock |
| One workspace per agent | If another session works in the same folder, new work goes to .worktrees/<branch>/ at the root you work in (never inside a project folder) and is never committed. A post-merge hook retires it once the branch lands. | rsc isolation off |
| The agent picks the method | FTD for simple changes, ASDD for complex ones. The agent decides and says why. | Ask for the other lane |
| Knowledge reaches everyone | 01-TOOLS/, 02-DOCS/wiki/ and 02-DOCS/attachments/ travel through one exchange branch, rsc/knowledge, and reach main inside your normal pull requests. | rsc knowledge-sync off |
Orca worktrees. Set "worktreeManager": "orca" in .rsc.json to retain externally managed
checkouts even when Orca is unavailable. rsc also recognises a matching Orca CLI response, and never
removes these checkouts through plain Git. Setup and cleanup
use the pinned harness version and Orca's lifecycle hooks; workspace lineage does not silence
warnings about unverified concurrent sessions.
How it knows a project is complex. A hook counts what anyone can check: a CI setup, a deployment
file (Dockerfile, vercel.json, fly.toml…) or at least two people in the last 50 commits. The
answer you gave at install always wins over this detection.
Knowledge sync, step by step
ana · feat/login edits 02-DOCS/wiki/api.md ──► rsc/knowledge (when her turn ends)
eric · feat/payments 📥 1 change from Ana ◄── rsc/knowledge (before his next message)
main · protected untouched, gets it inside the next merged pull request
new · clones main has it all after the first message
- When a turn ends, your changes in those folders are committed on your branch as
📝 docs(auto): …and sent torsc/knowledge. Only the copy onrsc/knowledgecarries[skip ci], so your own pushes still run CI. On a closedmain, or with code of yours still uncommitted, nothing is committed on your branch: the snapshot only goes torsc/knowledge. - Before each message, what teammates sent comes into the branch you are on as a
📥 docs(auto): synccommit, and you are told in one line. Only knowledge folders are touched. - It never pushes to
main, pushes your code, brings in anybody else's code, syncs your personaluser-profile.md, or overwrites a file you are editing.
It runs in the turn hooks of Claude Code, Codex, Gemini, Cursor, OpenCode and DeepSeek Harness. It is a project switch: if one person stopped sending, the rest would stop seeing their work.
Sharing the harness through git
Commit these: .rsc.json (which assistants, which skills, which catalog version), 01-TOOLS/,
02-DOCS/, and skills or agents you wrote by hand. rsc ignores the rest for you: .rsc/ (machine
state) and the skill entries it manages (symlinks here, copies on Windows).
Three files carry the harness through git: .rsc.json, .claude/settings.json and
.claude/rsc-bootstrap.mjs, the small file that notices in a clone that the rest is not built yet.
Commit all three. Because rsc-bootstrap.mjs runs on every session, review changes to it the way you
would review a CI workflow.
Whoever clones runs one command and gets the same harness, at the version the project pinned in
its .rsc.json as catalogVersion:
npx @ericrisco/rsc@<catalogVersion> sync
You do not have to know that. Open the project and the assistant tells you, in the first message,
what is missing and the exact command, naming the pinned version. It asks; it never installs on its
own. A teammate who clones in three months gets what you had, not what shipped since. After a
git pull, rsc doctor tells you what no longer matches; nothing is written by a pull.
Own skills. A skill your team wrote lives in the repo and works for whoever clones. rsc never installs, updates or overwrites
it: its version is the commit. Installing a catalog skill with the
same name is refused, and doctor lists what is yours by reading the files. Declaring a skill under
ownSkills still works.
Git permissions
A harness installed from scratch lets the agent run git commit, git push and gh pr create
without asking, because those steps close every lane. A force-push still asks, and in Claude Code a
commit on a closed main is still refused. It is saved as gitPermissions in .rsc.json.
| Assistant | Where it goes |
|---|---|
| Claude Code | .claude/settings.json → permissions.allow (force-push under ask) |
| Codex | .codex/rules/rsc-git.rules (force-push → prompt) |
| Gemini | .gemini/settings.json → tools.allowed |
| OpenCode | opencode.json: the permissions list on OpenCode 2, permission.bash on 1.x. An opencode.jsonc is never rewritten; rsc prints the rules to paste. |
| Cursor, DeepSeek Harness | Not covered: neither has a safe per-command allow list. |
rsc git-permissions status | on | off explains, per assistant, what rsc controls and what is left
to the assistant.
Memory between sessions
On supported local targets, rsc checkpoints observable repository state (branch, worktree, HEAD, changed paths, commits, SDD status) and injects it before the first action of a new session in the same checkout.
- Full: Claude Code, Codex, Gemini CLI, OpenCode and DeepSeek Harness. Codex asks you to trust the
project hook once with
/hooks. - Assisted: Cursor desktop, through an always-on rule that reads before acting.
- Never cloud: the memory runtime makes no network request.
The journal never stores prompts, responses, tool output, file contents or secrets. It stays in a
git-excluded local path, keeps 30 days, and injects at most 4,096 bytes. rsc memory off disables it.
Review that only brings you what is real
In ASDD, review runs inside every task, as deep as rsc risk says: none for docs, one fresh-context
reviewer for ordinary code, three adversarial reviewers (correctness, security, tests) for auth,
billing, CI or migrations. rsc review ledger caps the fix loop at three rounds and never lets a
finding be raised twice, and rsc review escapes turns every revert into a case for the reviewer. The
three reviewers
often report the same defect in different words, and a reviewer hunting for problems can overstate
one. So rsc review consolidate merges the duplicates, and every serious finding left goes to a
fresh finding-verifier agent whose starting position is that the finding is false. It blocks the
merge only if the verifier reproduces or traces it. You get "11 reported → 4 unique → 2 confirmed",
with the refuted ones listed and their reason.
It talks so you understand
- Short sentences, one idea each, in the style of ASD-STE100 (the controlled writing of aircraft manuals), always in your language.
- The answer first. Every answer stands alone, without "that fix" or "as above".
- One setting: technical, or with analogies.
- A ladder when you do not follow: text, then a diagram, then an HTML page, and a video only if you ask.
Every turn closes with a short compass: where you are, and the next step as a question. Text you send
to other people (emails, posts, READMEs) goes through unslop, so it sounds like a person.
Supported assistants
The real files land once in .rsc/skills/<id>/; each assistant gets a symlink or a converted file.
The wizard asks which ones; --target a,b does it non-interactively.
| Target | Skill destination (→ .rsc/skills/<id>/) | Always-on detector |
|---|---|---|
claude | .claude/skills/<id>/ → symlink (copy on Windows) | SessionStart hook in .claude/settings.json |
codex | .codex/rsc/<id>/ → symlink | block in AGENTS.md |
copilot | .github/rsc/<id>/ → symlink | block in .github/copilot-instructions.md |
cursor | .cursor/rules/<id>.mdc (converted) | always-apply rule |
gemini | .gemini/rsc/<id>/ → symlink | block in GEMINI.md |
windsurf | .windsurf/rsc/<id>/ → symlink | rule in .windsurf/rules/rsc-suggest.md |
cline | .clinerules/rsc/<id>/ → symlink | rule in .clinerules/rsc-suggest.md |
antigravity | .antigravity/rsc/<id>/ → symlink | block in .antigravity/AGENTS.md |
zed | .zed/rsc/<id>/ → symlink | block in AGENTS.md |
continue | .continue/rsc/<id>/ → symlink | rule in .continue/rules/rsc-suggest.md |
roo | .roo/rsc/<id>/ → symlink | rule in .roo/rules/rsc-suggest.md |
amp | .amp/rsc/<id>/ → symlink | block in AGENTS.md |
opencode | .opencode/rsc/<id>/ → symlink | block in AGENTS.md |
deepseek | .dsh/skills/<id>/ → symlink (discovered natively) | block in AGENTS.md |
pi | .pi/skills/<id>/ → symlink (copy on Windows; discovered natively) | block in Pi's selected project context file |
jules | .jules/rsc/<id>/ → symlink | block in AGENTS.md |
junie | .junie/rsc/<id>/ → symlink | block in .junie/guidelines.md |
kiro | .kiro/rsc/<id>/ → symlink | doc in .kiro/steering/rsc-suggest.md |
aider | .aider/rsc/<id>/ → symlink | block in CONVENTIONS.md |
codex,zed,amp,opencode,deepseekandjulesshare one rootAGENTS.md; the block is written once. Pi shares it when that is the context file its native loader selects.
DeepSeek Harness (
dsh) has no project-level hooks, so once per machine rsc adds one marked block to~/.dsh/cordis.patch.ymlthat runs the hooks of whichever project the session is in. Restart dsh once after the first install; delete the block to turn it off.
Pi: select
--target piduring onboarding, then run/reloadin Pi to discover the installed skills. Invoke one explicitly with/skill:<id>. Pi loads project resources after project trust is granted; rsc preserves your.pi/settings.jsonand extensions. This target uses Pi's native skills and context files. Its context loader selects the first readable file in this order:AGENTS.override.md,AGENTS.md,AGENTS.MD,CLAUDE.md,CLAUDE.MD. rsc adds its marked block to that file, preserving your instructions; it createsAGENTS.mdonly when none exists. If a new override hides the block, doctor reports the missing wiring and sync writes the block into the selected file. It does not install a custom extension, subagents, automatic session-memory hooks, or tool guards. Pi has no built-in subagents; skills that require independent reviewers need an external review. The instructions request an update check on the first turn, as for other targets without a wired session hook.
| Targets | Stack agents | Native commands | Session memory |
|---|---|---|---|
| Claude Code | yes | agent + memory entries | full |
| Codex | yes | no separate surface | full after /hooks trust |
| Cursor desktop | yes | yes | assisted |
| Gemini CLI, OpenCode | yes | yes | full |
| DeepSeek Harness | unsupported | unsupported | full (machine bridge) |
| Pi | unsupported | native /skill:<id> (no generated command files) | unsupported |
| GitHub Copilot | yes | yes | unsupported |

manifest.json is the generated public inventory: 34 agents (5 base + 29 selective specialists) and
53 command entries (20 fixed + 33 stack aliases). Unsupported means rsc writes nothing for that
surface. Generated agents carry no model: on OpenCode, so they use the session's model; pin one for
the team with rsc agent-model <target> <model>. If you edit a generated agent, rsc sync keeps your
file, and rsc agents reset <name> takes rsc's version back after a backup.
CLI
rsc below is short for npx @ericrisco/rsc. Without a global install (npm i -g @ericrisco/rsc),
the bare rsc answers command not found: type the npx form.
# Setup

rsc reassess # check deferred components against new evidence
rsc add fastapi postgresdb # install skills by name

rsc doctor # harness health and onboarding readiness
rsc repair # put the harness back to what is declared
rsc backups | restore latest # project-local snapshots
rsc uninstall <id> | purge # remove one skill, or everything rsc installed
rsc doctor
doctor answers two questions, on separate lines:
Harness health: healthy
Onboarding readiness: pending
Pending: 02-DOCS/wiki/sdd/constitution.md (draft)
Harness health says whether what is installed works, and it is the only thing the exit code
follows. Onboarding readiness says whether onboarding is finished (ready, pending,
incomplete, or not onboarded for a manual install); it never changes the exit code.
Something's off? rsc repair
If the harness is wired for the wrong assistant, a hook runs several times, or skills appear that you
never asked for, run npx @ericrisco/rsc@latest repair. It shows what it found before touching
anything, keeps a recoverable copy, and never touches skills or agents you wrote by hand. Add
--dry-run to see the pass without writing.
Update
rsc updates itself. At session start it checks npm. A release in the same major installs in the
background and takes effect next session; a new major asks first. To turn it off, create
.rsc/.no-auto-update. By hand: npm install -g @ericrisco/rsc@latest && rsc sync. Every sync
snapshots the project first, so rsc restore latest undoes a bad update.
Build a sales page and VSL from the same offer
The VSL sales pack, added in 3.7.0, connects buyer evidence to the offer, the buying journey, and a video sales letter (VSL). It is a curated selection of ordinary rsc skills; each remains usable alone.
| Step | Skill | Deliverable |
|---|---|---|
| Understand the buyer | customer-research | Sourced needs, objections and buyer language, with gaps and publication permissions. |
| Define the exchange | offer-design | What the buyer gets, why it helps, delivery limits and supported terms. |
| Plan the route | sales-funnel | Pages, decisions, exits, recovery paths and measurement handoffs. |
| Write the video | vsl-script | Spoken script, feasible timing, scene cues and evidence for each claim. |
| Write the page | landing-copy | Page text aligned with the same offer revision and video. |
In an existing rsc project, this command adds the core selection:
npx @ericrisco/rsc add customer-research offer-design sales-funnel vsl-script landing-copy
Use design and your web-stack skill to build the page; use remotion-video or your editor to produce
the video. Add analytics and ab-testing when you are ready to measure the result. These are separate
capabilities, not an automatic payment integration or a promise that the page will convert.
Try this request after installing the selection:
Use the research and product facts we already have to define one offer.
Plan the shortest buying journey, write its VSL, and prepare the landing copy.
Keep the price, scope, evidence and next action consistent across all three.
Separate missing proof from publishable claims. Show what still needs production or implementation.
Evaluation status: initial blind comparisons met the quality threshold for all four new skills;
only offer-design met the required improvement over the no-skill baseline. The others ship with
that limitation recorded in their evals/README.md. Repeated-trial validation remains open.
The same workflow works for a free tool: the next action can be trying or installing it. No invented price, customer testimonial, deadline or guarantee is needed to explain a useful product.

Why you can trust it
The harness is built on ten principles. Three of them shape everything else:
- Evidence over claims. A task is done when its check was observed, not when someone believes it
works. The same rule applies to this README: every number here comes from
manifest.jsonor the code, and tests check that the README and the code agree. - A gate that checks nothing is worse than no gate. Every rule rsc declares binding ships with the mechanism that enforces it and a test that watches that mechanism fail and pass.
- Friction proportional to risk. Silence for the trivial, ceremony only where failure is expensive. A harness that nags on harmless work gets switched off.
Known limits, stated openly: the hard guards run only in Claude Code; OpenCode 2 and Windows have had less real-world testing than macOS and Linux; and the session memory is local by design, never cloud.
Contributing
skills/<name>/ is the single source of truth. Each skill is a directory whose SKILL.md frontmatter
drives triggering and recommendations:
---
name: my-skill
description: Use when [specific triggers]… NOT x (that is sibling).
tags: [keyword, keyword] # what the consult advisor searches over
recommends: [sibling-skill] # what the system offers to install next
origin: risco
---
After editing any skill:
npm run manifest # regenerate manifest.json from skills/*/SKILL.md
npm run validate # validate frontmatter and recommends integrity
npm test # unit and integration tests
bash scripts/eval-lint.sh # validate every skills/*/evals/cases.yaml
manifest.json is generated, never edited by hand; CI fails if it is stale. The rubric every skill is
held to is scripts/skill-rubric.md. Bug reports are welcome as GitHub issues. Release notes are in
GitHub Releases.
Third-party skills
Most of this catalog is written here. These are not, and they keep their author's credit:

Adapted, not mirrored: each carries rsc frontmatter, routing evals and hand-offs to its siblings. The craft bar in them is the original author's.
Shared risk policy and external branch checks
Commit .rsc-risk.json at the workspace root to share risk rules across clones and submodules:
{
"version": 1,
"trunks": ["develop", "integration"],
"repositories": { "Catman": { "trunks": ["develop"] } },
"testRepos": ["CatmanTest"],
"rules": [
{ "class": "schema", "tier": 2, "path": "\\.Table\\.al$",
"removed": "^\\s*field\\s*\\(", "productionOnly": true,
"because": "Removing a field changes the stored schema." },
{ "class": "api", "tier": 2, "path": "\\.Page\\.al$",
"contains": "PageType\\s*=\\s*API", "removed": "APIVersion",
"because": "The API contract changes." },
{ "class": "platform", "tier": 2, "path": "(^|/)app\\.json$",
"jsonKeys": ["dependencies", "idRanges", "runtime"],
"because": "Dependencies or platform requirements change." },
{ "class": "editor", "tier": 0, "path": "^\\.vscode/settings\\.json$",
"because": "Editor preferences only." }
]
}
Rules can also use added, deleted: true and repos: ["relative/path"]. Conditions in one rule
must all match. contains reads the file before and after the change; added and removed read
changed lines with whitespace differences ignored. JSON keys are top-level keys. Renames are
checked as both old and new paths. Matching rules take their highest tier; explicit zero replaces
ordinary-code defaults, but built-in risk classes and the secrets/harness floors still apply.
Patterns are case-insensitive and limited to 200 characters; repeated groups, lookarounds and
backreferences are rejected. Content lines over 2,000 characters are skipped. Rule evaluation has
a hard one-second timeout and an 8 MiB input budget: exceeding either reports an error at tier 2.
At most 64 rules and 16 trunk candidates are supported.
rsc risk and the push gate use the policy from the workspace trunk, including repository
settings and exemptions. A proposed policy cannot relax its own outgoing branch. A policy first
added on a feature branch stays inactive until it lands. Use rsc risk --policy-preview to inspect
the proposed policy explicitly; the output identifies its source. Local .rsc/sello-config.json
remains available for existing settings and bootstrap. Initial trunk discovery uses origin/HEAD,
then main, master or develop; for another name, set the remote HEAD or the local trunk first.
Once a trusted policy exists, its trunk candidates select the nearest branch by commits ahead.
rsc doctor reports an installed ASDD gate that cannot find a trunk.
Specs accept branches: [feature/a, fix/b] or a YAML block list, as well as the existing branch:.
An FTD under 02-DOCS/wiki/ftd/ can link its branch to a spec with spec: <slug>. Optional trusted
asddGate settings are require: "spec" (default: full panel), exemptBranches: ["^chore/back-merge-"]
and cherryPickSuffix: "-master". These settings take effect after the policy reaches the trunk.
External PR tools can run rsc spec gate --branch-check --repo <directory> [--branch <name>] from
the workspace, or run the same command inside a submodule. Exit 0 means allowed, 2 means denied,
and 1 means the check could not run. --branch evaluates that branch even when it is not checked
out. The hook resolves ordinary git -C, directory changes, shell -c/eval wrappers and gh pr
commands. Arbitrary scripts, aliases and shell functions need the explicit CLI check; their bodies
cannot be inferred from the shell invocation. This is a local review aid, not a remote-server policy.
Sync preserves opt-outs declared by teammates in .rsc.json. Existing local markers remain local
choices; doctor reports differences. To explicitly re-arm a team gate, remove its local marker and
run an explicit install, which records the new decision; sync alone does not erase the declaration.
