feat(skills): openspec-beta skills, installed once per machine, with stable IDs and short decisions - #2134
Status: Ready for review. Merge after #1979, then #2198. Nothing in the openspec CLI changes; nothing changes for an existing project until someone installs the skills.
Why
openspec init copies 12 long skills into every project, and each one repeats the same rules, so people find them hard to read and agents skim them.
An audit of 55 real proposal-writing sessions found agents read the project's existing specs before drafting only 44% of the time. When they did read, 23 of 24 proposals were visibly better for it. The audit's recommendation was to build an explicit "look at the specs first" step into the proposal workflow. That is what these skills do.
What it does
One openspec-beta skill explains OpenSpec: eight principles and five one-page guides. A short skill per task points into it.
Reads the specs first. Propose and ff have a dedicated step before any drafting. Measured on expressjs/express, today's skills read the specs in 4 of 15 runs; the beta in 15 of 15.
The skills CLI removes by install source, so that one name takes all 12 beta skills and any copies of the earlier skills an older npx skills add left. The command is in the skills' own references/install.md, so you can also just ask your agent to "remove OpenSpec beta". With #2198, openspec update is what keeps one skill set: it removes the project's per-project OpenSpec skills while the beta is installed, and writes them back byte for byte once it is gone. Nothing is backed up or registered. Documented in docs-lab, the docs site's source, as Customize › Beta skills, and in docs/skills-beta.md.
This PR changes no CLI code
Every existing file under src/ is byte-identical to main; the beta is new files only. Against a build of main:

The 43-scenario suite and both real repos were run with main's unmodified CLI driving and grading, so only the skills differ. The beta scores 211/215 there and 211/215 on this branch's build, which is what the table above would predict: the CLI is the same either way.

Where it is not better:
ins-iqr delta specs, judged 2 to 7 for today. The beta extends insyra's datalist-quantile capability the way insyra already documents it, including a CLI requirement beside the existing "The CLI prints a quantile" (18 of insyra's 204 specs document a CLI that way). The judge prefers specs scoped to the literal request. Two candidate fixes were tried and reverted: neither moved the verdict, and telling the agent to ignore a project's conventions is the wrong lesson.
One propose-crowded-spec run in ten left a requirement with more obligations than it found.
Bracketed IDs cost prose readability. Judges call [DLQ-n] clutter even while preferring the plans that carry them. A deliberate trade.
Rerun any of it with scripts/skill-eval: --skills <checkout> pairs these skills with any CLI build.
Notes
Today's skills are frozen. The beta has its own templates and its own parity test; main's parity test still guards today's skills byte for byte and passes unchanged.
skills/ now holds only the beta set. Where an older npx skills add left the previous skills, skills/README.md has the command that removes them.
Maintainer skills are hidden from skills.sh (metadata.internal: true), with a test that fails if one is added unmarked.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
The setup command installs skills for detected agents, migrates older files, supports dry runs and refresh, and restores backups on revert. Init can offer machine installation.
Context JSON includes project_context. Documentation describes beta skill installation, references, setup, and rollback.

Ask about unfinished artifacts before the preview archives the change.
Step 3 only records artifacts that are neither done nor skipped. Step 4 then runs openspec archive "<name>" --json without --yes. When tasks are complete and no spec delta exists, the CLI has no confirmation status for an unfinished artifact. The change can therefore be archived before the user sees the step 3 findings.
Suggested fix
3. **Check what is unfinished**
Run \`openspec status --change "<name>" --json\` and note any artifact that is neither \`done\` nor \`skipped\` (\`skipped\` satisfies the requirement: the change declares \`skip_specs\`).
+ If any artifact is unfinished, show the list and ask whether to continue before step 4. On "Cancel", stop.

- Each workflow states its steps first and keeps rarely needed detail in
references/. Shared rules are written once in references.ts.
- Archive previews with `openspec archive --json`, asks about each warning
and any unfinished artifact, then lets the CLI merge, validate, and move,
or refuse and change nothing.
- Explore keeps a living draft (scope, capabilities, requirements, open
questions). Propose builds from the settled scope, reads the existing
specs, checks what the code already does, and plans only the gap.
- Spec guidance: one obligation per requirement, a scenario for each way the
requested behavior fails with concrete values and no invented validation,
no internal names, and compatible changes by default.
- tasks.md ends with an "Update the specs" task and apply ends by offering
to archive (#1968). `openspec context --json` returns project_context.

…orkflow
The openspec-beta router (user-invoked, like pstack's poteto-mode and Matt
Pocock's ask-matt) holds what OpenSpec is, which workflow to run, and the
rules every workflow shares; each workflow's steps live in
references/<workflow>.md. Each openspec-beta-<workflow> skill is a short
pointer into it, so workflows autocomplete, every rule lives once, and
planning workflows state the plan-only boundary where they are invoked.
Descriptions are quoted so strict YAML parsers (npx skills add) accept them.
The skills.sh copy in skills/ is this set.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…vert
`openspec setup` installs the openspec-beta skills for every coding agent
it finds: a Claude Code plugin, and ~/.agents/skills for Codex, Cursor,
Gemini CLI, OpenCode, and others. It never deletes: older OpenSpec skills,
/opsx command files (inside a project), and anything already under the beta
names (an npx copy and its symlinks) move into a dated backup with a
manifest written after every move. `openspec setup --revert` puts every
file back. Moves fall back to copying across disks, and an interrupted
setup can still be reverted. `openspec update` refreshes the install.
An end-to-end test runs init, setup twice, update, and --revert through the
built CLI and checks the home folder and project end byte-for-byte where
they started, on macOS, Linux, and Windows.

Runs real requests through headless Claude Code against any two checkouts,
on the bundled todo library or a real project (--fixture), grades each run
with the OpenSpec CLI and the file system, and compares plans and skill
text with blind judges. See scripts/skill-eval/README.md.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…de CLI
An opt-in test (OPENSPEC_REAL_CLAUDE=1) registers the openspec-beta plugin
with the real claude binary in a throwaway home, checks Claude Code lists it
and its skills, reverts, and checks it is gone. A new CI job installs a pinned
Claude Code and runs it with the end-to-end journey on Linux, macOS, and
Windows. It is not a required check, since it depends on an external package.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…ills
With the real CLIs on PATH, the opt-in test checks that `codex debug
prompt-input` and `gemini skills list` show the openspec-beta skills after
setup and none after --revert. CI installs pinned versions and requires all
three agents, so a failed install fails instead of skipping.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- Skills from an earlier namespace carry the layout marker too, so setup now
treats any OpenSpec skill outside the current namespace as older and backs
it up.
- The plugin name is recorded; when it changes, setup unregisters the old
plugin before registering the new one, and revert uses the recorded name.
- Tests: one beta to the next refreshes in place and drops turned-off
workflows; a rename moves the earlier skills and unregisters their plugin.

…he beta in the changeset
The repo's four maintainer skills in .agents/skills now set metadata.internal,
which the skills CLI documents as hidden from normal discovery, so
`npx skills add` lists only the openspec-beta skills. The changeset now
describes what this PR ships.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Codex on Windows finds the home folder through the OS profile, not
USERPROFILE, so it could not see skills in the test's sandboxed home. On a
Windows CI runner, which is discarded after the job, the test now uses the
real home. The job also moves to Node 22, which Claude Code requires.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Setup only wrote `~/.agents/skills` when it recognised one of eleven agents by
the folder it creates. That list can never be complete: `AI_TOOLS` already
knows 49 tools with a skills directory, so a Pi or Zed user running
`openspec setup` was told "No coding agents found" and got nothing.
`~/.agents/skills` is the cross-vendor Agent Skills location, so the copy
there is now written unconditionally. An agent OpenSpec has never heard of
picks the skills up by honouring the convention rather than by waiting for us
to learn its name, and an agent installed later finds them without re-running
anything. Detection now only shapes the summary, which says "Any agent" and
names the folder when it recognises none. Claude Code stays on the plugin,
since it does not read that folder.
One copy is also the structural answer to #2180: a harness that reads both its
own folder and the portable one finds two skills of the same name, keeps one
and warns on every start. OpenSpec now writes skills to exactly one container
folder and never a harness-native copy, which a new test asserts by walking
the home directory and requiring that `~/.agents/skills` is the only one.
Checked by hand on machines whose only marker was `.pi`, `.config/zed`, and
nothing at all: each installs the 6 skills, the summary explains the folder,
and `--revert` removes all of them.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Setup moved every `openspec-beta*` folder it had not written. A skill of the
user's own named `openspec-beta-mine` collides with nothing OpenSpec installs,
yet it disappeared from `~/.agents/skills` on setup and only came back on
revert. Narrowing that to the names this install writes fixed it but regressed
the case it was there for: the committed `skills/` mirror carries the layout
marker and no `generatedBy`, so an `npx skills add` copy of a workflow this
profile does not install - `openspec-beta-ff` and five others - was then left
behind for the agent to load. Both marks now count: a name this install
writes, or the layout marker, which only these generated skills have. Verified
against the real skills CLI: setup over a full npx install leaves exactly the
6 it installs, and a hand-written prefixed skill survives setup, update and
revert untouched.
The summary also called everything it moved "older OpenSpec files" and named
only the folder it came from, so a user whose own file moved could not find
it. It now says how many files moved, from where, into which backup, and that
`--revert` puts them back.
While measuring the Claude-only risk flagged on this PR, Claude Code's own
debug output settles it: "Loading skills from: managed=..., user=~/.claude/
skills, project=[]" - it does not read `~/.agents/skills`, and it reports
skipping duplicate entries silently rather than warning. The canonical copy
beside the plugin costs disk, not correctness.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Four reviews ran over this PR in parallel. Reproduced and fixed:
DATA LOSS, case-folding filesystems. A folder spelled `OpenSpec-Beta` answers
to the name setup writes, so `isOurs` read the user's SKILL.md, skipped the
`rm`, and the write landed inside their folder - overwriting it with no
backup, and revert could not see it afterwards. I hit this for real: a review
agent's own probe folder on this machine ended up holding our generated
router. The migration now treats it as the clash it is, proven by the
filesystem (our name resolves while nothing is spelled that way) rather than
by folding case, which would wrongly claim a separate folder on Linux.
UNRECOVERABLE REVERT. A restore that threw (a permission, a read-only parent)
aborted after the plugin and shared skills were already gone and before the
record was cleared, so every later `--revert` died on the same file. It now
reports the backup, keeps going, and names where the kept backup is.
`openspec update` ABORTED ON A BROKEN MACHINE INSTALL. An `~/.agents` someone
made a file, or a symlinked skill folder, took down the project update too -
which worked on `main`. The refresh is now advisory: it warns, names
`openspec setup`, and the project is still updated.
`openspec update` OUTSIDE A PROJECT exited 0 once a machine install existed,
swallowing "No OpenSpec directory found". The exit code scripts read is back.
DELETED THE USER'S FILES. `update` pruned every `references/*.md` a skill does
not ship, but per-project skills ship no references, so a `references/` folder
beside one is the user's - and `main` leaves it. Confirmed against a build of
`main`: theirs survived there and was deleted here. Pruning now applies only
to a skill that ships references, so the beta still drops a stale guide.
WRONG INSTALL COMMAND. `@fission-ai/openspec@beta` is not unpublished as the
guide claimed: it points at `1.6.0-beta.1` from July, so that command
downgrades from 1.16.0 to a CLI with no `openspec setup`. The docs now install
the default branch and say why. This also reverses my own earlier change,
which pointed the router's "No CLI" hint at `@beta` on a reviewer's suggestion
I did not check - that hint now names the working CLI.
DOCS THAT CONTRADICTED THE CODE. Setup moves aside only skills OpenSpec wrote
(they carry `generatedBy`), so it does not touch an `npx skills add` copy of
the older names; two documents claimed it did, and `skills/README.md`
contradicted itself a paragraph apart. The per-project skills do not carry the
beta's shorter steps - they are byte-identical to the previous release - and
one guide list named four of the five guides.
A Windows-only CI failure is fixed too: my own test asserted a POSIX path
where `tilde()` builds one with the platform separator.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Four more defects, each reproduced against the real `claude` CLI first.
A setup that threw part way left no record. Writing the shared skills fails if
something made `~/.agents` a file, and by then the plugin was written and
registered - but the record is saved last, so `--revert` answered "nothing to
revert" and the user had a registered plugin with no documented way to remove
it. The record is now written from a `finally`, so it survives the throw, and
it follows what is on disk rather than whether registration succeeded. Revert
also falls back to the disk when the record is missing for any other reason, a
config restored from a backup among them.
That also fixed the dangling marketplace: `marketplace add` can succeed while
`plugin install` fails, and the old record wrote `claudePlugin: false`, so
revert skipped both the uninstall and the marketplace removal while still
deleting the folder the marketplace pointed at. Revert now unregisters it, and
treats "not found in installed plugins" as the goal rather than an error to
show, so a partial registration reverts without a false alarm.
A refresh never registered. `openspec update` passes `register: false`, so a
user who installed Claude Code after `openspec setup` got the plugin files
rewritten on every update, never registered, while the summary claimed the
plugin was updated. A refresh now completes that registration once, and the
summary names the plugin only when Claude Code will actually load it.
`openspec init`'s machine-install offer moved this project's `/opsx` command
files without saying so, and defaulted to yes. It now counts them from a dry
run, says how many would move and that `--revert` restores them, and defaults
to no when anything would.
Verified end to end with the real CLI: setup registers and Claude lists the
plugin, update refreshes it, revert leaves no OpenSpec file and no plugin -
only Claude Code's own state and OpenSpec's ordinary config.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
`docs/commands.md` and `docs/customization.md` were rewritten to say
`/opsx:archive` runs `openspec archive --json`, hands the merge to the CLI and
asks before updating main specs. The `/opsx` surface is frozen by this PR, and
the generated command still does the old thing: 0 occurrences of
`openspec archive --json` or `archive --yes`, and an inline `mv`. The new prose
describes `skills/openspec-beta/references/archive.md`. Both files, and
`docs/supported-tools.md`'s claim that per-project skills ship a `references/`
folder (they ship none - verified against a real `init`), go back to `main`.
`docs/cli.md` keeps its new `openspec setup` section, with the sample run
corrected to what the summary prints: "Moved 24 files out of the way, from:",
machine paths with `~`, and the backup path plus the `--revert` line it
omitted. It also no longer implies setup leaves `npx` copies of its own names
alone - it moves those into its backup - and says one skill per workflow "in
your profile", since the default profile installs five of twelve.
A docs-claims test pins the generated lines, so this sample cannot drift again
without a test saying so.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The CLI's tasks guidance ends every change with a tracked
`## N. Update the specs` group: "one task to sync this change's delta specs
into the main specs and verify `openspec validate --specs` passes". Apply is
the workflow that runs tasks, and it said nothing about how - zero mentions of
sync anywhere in apply.md - while archive's guardrail says not to edit main
specs by hand. An agent reaching that task had no procedure and a rule
elsewhere telling it no, so it either hand-merged the way deltas.md warns
against or left the task unchecked and called apply complete.
Apply's step 4 now names that task as the merge, points at the sync steps, and
says what archive reports afterwards (no spec update, zero totals, because the
specs are already current) so the summary is not read as nothing happening.
Two things this did NOT do, both on second thought:
The pointer is injected by the router's REWRITES, not written into the
template. Only the router ships `sync.md`; the same template also deploys
standalone, and `skill-generation`'s "ships the references every deployed
skill points to" test caught the dangling pointer. Verified both ways: the
beta's apply.md names `references/sync.md`, the per-project apply skill names
it zero times.
I also qualified archive's and bulk-archive's "Do not edit main specs ... by
hand" guardrail, and reverted that. Five tests pin the phrase for #1827 and
#1393 - each archive is one atomic `openspec archive` call, no hand `mv`, no
hand merge - and loosening it to buy consistency with one conflict-path line
in bulk-archive would trade a real invariant for a wording nit.

The router's table said explore "(writes nothing)", while explore.md says it
may create change artifacts once the user confirms, and routes a "capture this
as a change" request straight to propose. An agent reading only the table
refuses that request; one reading explore.md writes files the table promised it
would not. The row now says it writes only what you OK.
Onboarding showed a folder tree with proposal.md, design.md, specs/ and
tasks.md as "empty" right after `openspec new change`. That command creates
`.openspec.yaml` and nothing else - verified - so an agent either filled in
files it thought existed or described a structure the user could not see. They
are now labelled as not created yet.
The same tutorial drew a box with `┌ │ └ ─` inside the block that teaches
explore mode, whose own rule is plain ASCII only because other glyphs render
at different widths and break alignment (#983). Redrawn with `+ - |`.
Propose keyed its no-project handling off the literal code
`no_openspec_root`. A user with a registered store gets
`no_root_with_registered_stores` instead (src/core/root-selection.ts:475), so
they fell through to "on any other error, stop and report it" and never got
the ask-whether-to-init handling. It now keys off `root` being null, which is
what SKILL.md already does and what covers both codes. I could not register a
store non-interactively to reproduce the store path end to end; the code's
existence is the evidence.
Onboarding's two "commands you have installed" tables listed eight commands
and omitted update, bulk-archive and onboard, all of which ship. They use the
same profile-aware helper as the others, so a row drops out when its workflow
is not installed.
SKILL.md was 5 bytes over budget after the explore row, so the wording is
tighter rather than the budget looser. Two tests pinned propose's old code
name; they now pin the null-root wording and the second code.

….path
Onboarding archived with a bare `openspec archive "<name>" --yes`, on the
user's real codebase, on their first run. `archive.md` does the opposite for
good reason: run it without `--yes` first, because the CLI then moves nothing
that needs confirmation, read what it reports, and ask before updating the
main specs. The tutorial skipped all of that, so the one place a user is
learning the workflow taught them the unsafe shape of it. It now previews,
says what the CLI reported, and asks before the `--yes` run.
SKILL.md told agents "Its `root` is the OpenSpec folder". `root` is an object:
`{"path": "...", "source": "nearest"}`. An agent using it as a path gets
`[object Object]`; propose.md already says `root.path`. Fixed to match.
That cost 5 bytes and SKILL.md had 3, so the explore row says "(writes only if
you OK)" rather than a longer phrasing - the budget stays where it is.

…finishes
The "What to say" table listed `/openspec-beta-explore` twenty lines after the
install table correctly told Claude Code users to type `/openspec-beta:propose`
- the plugin namespaces its skills, so the table's spelling is not the one they
have. One clause above the table now says so.
The removal command for an earlier `npx skills add` listed the 12 workflow
names but not the four maintainer skills that install also delivered, so a user
who ran it was left with `release-openspec` and the three docs skills and no
instruction covering them. Ran the documented command verbatim against a real
past-style install from `main`: 16 skills installed, 16 removed, none left.

The numbers say the beta plans better; a reader should be able to see it. This
prints one scenario's artifacts from both result sets next to each other, with
the final message each run gave the user.
It picks the candidate's median rep rather than its widest gap, and prints
every rep's count of cited requirement and decision IDs above the excerpt, so
the pair reads as typical instead of chosen. On express's `Retry-After`
request that count is 0 in all ten of today's runs and non-zero in seven of
the beta's, and the median beta task cites `[D1](./design.md#d1)`-`[D5]` and
"one test per scenario RA-1.1 to RA-5.2" where today's says "validation per
design.md" and "every scenario in the spec".

A machine where an earlier `npx skills add` installed openspec-propose and
the rest got the beta set beside them, so the agent loaded two OpenSpec
skill sets, and `openspec setup` (and its dry run) said nothing. Those
copies carry no `generatedBy`, so nothing proves they are ours to move and
setup still leaves them in place; it now lists them and prints the exact
`npx skills remove -g -y <names>` command for the ones it found.

…gree
The beta reached past its own skills in two places that every OpenSpec
user would feel, and those go back to what main does:
- The default schema (`schemas/spec-driven`) gained an "Update the
specs" last task group, new spec rules and a second scenario stub.
Every user reads it through `openspec instructions`, today's frozen
skills included, and the task group moved the spec merge from archive
into apply, which #1968 is still exploring. The schema, its template
and the docs-lab copy are main's again; the spec rules the beta needs
now live in its own guides (specs.md, decisions.md).
- Interactive `openspec init` offered the machine install as the
recommended default whenever it saw an agent. `init.ts` is main's
again: the beta comes only from `openspec setup` or `npx skills add`.
Main's skill parity test, which guards today's per-project skills byte
for byte, had been pointed at the beta templates. It is main's again
and passes unchanged; the beta keeps its own copy under
`test/core/templates/beta/` with `pnpm regen:beta-parity-hashes`.
Skill text fixes: the router auto-selects the only active change like
every workflow does; writing-an-artifact keeps the Principles (stable
IDs) where the schema's instruction is silent; ff states its scope and
raises costly decisions like propose; update drops an undefined
"Start Fresh" heuristic; sync treats an ADDED block that already exists
as MODIFIED, so it cannot delete what the block leaves out; onboarding's
tasks example cites requirement IDs; skills/README installs with -g to
match its removal commands.

…write
A continue run appended a priority clause, with a second SHALL, onto the
existing "Adding a todo" requirement: the exact growth specs.md warns
against. Propose and ff carry that rule in their write step; continue
reached specs.md only through "any guide the Principles point to", and
update named deltas.md but never specs.md. Both now name specs.md
directly, with the one-line reason.

…oard
The first 53 scenarios gave verify, update and ff one each, and
bulk-archive, new and onboard none. Eight more: bulk-archive with a
same-capability conflict and with an unfinished change, verify on a
correct change, update reconciling a design that contradicts its spec,
ff on a breaking request, new, onboarding's first turn, and the whole
onboarding cycle.
The whole cycle is a conversation, so a scenario can now list
`followUps`: each resumes the first turn's session, and the harness then
deletes that session's transcript and nothing else. Cost and tokens sum
across turns. Also maps the onboard skill, which the harness could not
start, and documents all 61 scenarios.

…t is
The beta came with CLI changes of its own: an `openspec setup` command
(machine install, Claude Code plugin, backups and `--revert`), a
`machineSetup` record in the global config, an `openspec update` step
that refreshed that install, a `project_context` field on
`openspec context --json`, and a refactor of skill-generation.ts that
`init` and `update` run. All of it is main's again.
The beta now installs with `npx skills add Fission-AI/OpenSpec -g -y`
and comes off with one `npx skills remove` command. The router carries
that command in references/install.md, naming exactly the skills that
were installed (a wildcard removes only the router), so an agent can
run it when asked. Nothing is moved or backed up, so there is nothing
to restore.
What used to need the CLI now uses what the released CLI already does:
explore and propose read project context from the root's config.yaml,
the way today's skills do. A test fails if any beta text names
`project_context`.
The beta's own code is new files only: beta-skill-generation.ts, the
router and guides, and beta template types that extend the core ones.
Every existing file under src/ is byte-identical to main, and against a
build of main every help text, completion script and JSON output the
skills read is identical, and `init --tools all` writes the same 472
files.
The CI job now opts in and out with the real skills CLI on every OS,
using the removal command from install.md.

The judge read the pristine fixture, not the fixture with the scenario's
`setup` applied, so for update-ripple it was never shown the `exportJson()`
and `todo-export` spec that setup seeds: 8 of 10 verdicts said both plans
had invented them, and the comparison turned on who hedged better about
code the judge could not see. It now applies `setup` to a temp copy and
shows that source plus any seeded specs. update-ripple goes from 2-10
against the beta to 5-5.

…ted ones
Blind spec judging on insyra's `ins-iqr` went 1-4 against the beta, with
its requirements missing the failure cases today's kept. The shared write
step now asks for the main case plus a scenario for each way the behavior
can fail, and, for behavior the code already has, for how it fails today
rather than new checks it was never asked to add. That scenario's spec
verdicts go to 3-5.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Both were added for `ins-iqr`, where blind spec judging favours today's
skills, and neither earned its place:
- The failure-scenario line repeated `references/specs.md` almost word
for word in the write step, and the verdicts moved 1-4 to 2-7, which
is no movement.
- "No command, flag or endpoint the request did not name" was wrong.
insyra's own `datalist-quantile` spec carries "### Requirement: The
CLI prints a quantile", so the beta adding an IQR CLI requirement
follows the capability it is extending; 18 of insyra's 204 specs
document a CLI that way. The rule would have taught the agent to
ignore a project's conventions, and it changed nothing anyway
(a CLI requirement in 6 of 9 runs before, 5 of 10 after).
`ins-iqr` stays a loss, reported as one: the judge prefers specs scoped
to the literal request, and the beta extends the capability the way the
project already documents it.

With #2198, `openspec update` gives a project no per-project OpenSpec
skills while the beta is installed and writes them back once it is
removed. So opting in is `npx skills add Fission-AI/OpenSpec -g -y &&
openspec update`, and opting out is the one `npx skills remove` command
followed by `openspec update`; `references/install.md`, docs/skills-beta.md
and skills/README.md now say so. On a CLI without #2198, `openspec
update` only refreshes the project, so the added step is harmless.

…2198
docs-lab is the docs site's source, and the beta had no page there. The
new Customize > Beta skills page covers opting in and out in one line
each (`npx skills add ... && openspec update`, and the one
`npx skills remove` command followed by `openspec update`), what happens
to today's skills while the beta is installed (per project, MiniMax Code
machine-wide, a tool that cannot see the beta left alone), and how the
skills fit together. docs/skills-beta.md and skills/README.md say the
same, including that `openspec update` prints the removal command for
old skills an earlier `npx skills add` left.

A run that left the change valid but the task unchecked counted as a
pass. Now a valid change must also have its one task done. Re-graded
from the saved runs, no verdict changes: every beta run validated with
the task done, and every run of today's skills still fails.

… 12 skills
`npx skills remove -g -y Fission-AI/OpenSpec` takes every skill the
skills CLI installed from this repository, which is the 12 beta skills
plus any copies of the earlier skills an older install left. The
router's install.md, the skills README, both beta docs pages and the
real-CLI test now use that one-name form in place of the 12-name list.

Status: Ready for review. Merge after #1979, then #2198. Nothing in the
openspecCLI changes; nothing changes for an existing project until someone installs the skills.Why
openspec initcopies 12 long skills into every project, and each one repeats the same rules, so people find them hard to read and agents skim them.An audit of 55 real proposal-writing sessions found agents read the project's existing specs before drafting only 44% of the time. When they did read, 23 of 24 proposals were visibly better for it. The audit's recommendation was to build an explicit "look at the specs first" step into the proposal workflow. That is what these skills do.
What it does
openspec-betaskill explains OpenSpec: eight principles and five one-page guides. A short skill per task points into it.[AUTH-3]) and decisions are short### D1headings that tasks cite (Stable IDs for requirements, scenarios and decisions #2167; the CLI side is feat(specs): stable IDs so renaming a requirement no longer breaks links or archive #1979).Install and remove
The skills CLI removes by install source, so that one name takes all 12 beta skills and any copies of the earlier skills an older
npx skills addleft. The command is in the skills' ownreferences/install.md, so you can also just ask your agent to "remove OpenSpec beta". With #2198,openspec updateis what keeps one skill set: it removes the project's per-project OpenSpec skills while the beta is installed, and writes them back byte for byte once it is gone. Nothing is backed up or registered. Documented in docs-lab, the docs site's source, as Customize › Beta skills, and indocs/skills-beta.md.This PR changes no CLI code

The 43-scenario suite and both real repos were run with main's unmodified CLI driving and grading, so only the skills differ. The beta scores 211/215 there and 211/215 on this branch's build, which is what the table above would predict: the CLI is the same either way.
