dsh 0.1.0-rc.8 imports and registers the client bundle by export const name, so a leftover dsh-plugin-browserskill id fails to load the 0.1.1 web UI.

Agents were stopping on popup and status copy that looked like a hard incompatibility. Keep the connection usable, reframe exit 5 as an unknown method, and ask users to upgrade instead of aborting.

Register bundled browser instructions at agent scope, prioritize foreground commands over thumbnail capture, and unify cancellation and session cleanup.
browser_screenshot declared every capture as image/png regardless of the
actual bytes. On Chromium/Edge builds where captureVisibleTab returns JPEG
bytes, the stored attachment reference recorded mediaType "image/png" against
JPEG bytes, so dsh-attachment-local's read-time metadata verification fails
with ATTACHMENT_CORRUPT ("Stored attachment metadata does not match its
reference"), surfacing as code UNKNOWN and triggering endless LLM retries.
- image.ts: sniff the capture's magic bytes (PNG/JPEG/WebP/GIF) and declare
that real media type to attachments.saveImage, instead of always "image/png".
- tools.ts: assemble the tool result from ref.mediaType (the store's verified
type) rather than re-declaring "image/png" as const, and relax the output
schema's const to the accepted media-type enum.
- tests: add a regression case asserting JPEG capture bytes surface as
image/jpeg.

The publish job named its GitHub Environment NPM_TOKEN, which is the
secret name rather than a deployment target, so the repository's
Deployments list showed a bogus NPM_TOKEN entry next to chrome-web-store.
The environment is now npm-publish; the secret it holds keeps its name.

Renaming the package to @wxg-prc-cpg/browser-skill-dsh-plugin left two
identifiers behind on the old directory name, and both are resolved by
name rather than by path.
cordis.patch.yml is the specifier the loader imports, so dsh failed with
ERR_MODULE_NOT_FOUND on startup and took the whole plugin tree down with
it — installing the published package made dsh unusable. The client
bundle registers itself under the same kind of key, which the web shell
looks up by package name, so the screenshot toolview and the observation
overlay were unreachable too.
The bundle id now reads package.json instead of repeating the name, so it
cannot drift again. Quoting is required in the YAML because a leading '@'
is reserved in plain scalars.

The extension is now published to Edge Add-ons, but every install path
still pointed Edge users at the Chrome Web Store. Both READMEs and
AGENT_INSTALL.md now name a store per browser, and `bsk doctor` offers
both listings when no browser is connected.
Two Edge-specific gaps went with it: Edge blocks content-script injection
on its own storefront the same way Chrome does, so the borrow-confirmation
overlay must treat microsoftedge.microsoft.com/addons as non-injectable;
and the Chinese README still described the pre-install.ps1 manual Windows
setup.
Also give the DeepSeek Harness section its npm package link and the
profile-start step, so plugin users have a complete path.

Stop writing overlay thumbnails into the durable attachment store. Each
session now holds only the current and previous PNG in process memory,
reuses the id when the hash is unchanged, and drops the rest on rotate,
remove, or dispose.
Add a Release dsh plugin workflow (dsh-plugin-v* tags or workflow_dispatch)
that reads NPM_TOKEN from the GitHub Environment of the same name. The
Cordis plugin id stays dsh-plugin-browserskill; only the npm package name
changes.
Add the missing blank line before the actions comment, and hoist
.tool-button:focus-visible above the wrap-hover rules so specificity
no longer descends.
- @browser-skill/ui and @remixicon/react move to devDependencies (the client
bundle inlines both; the host face never imports them — verified).
- Drop private, add license: MIT, ship the repo-root MIT LICENSE in files.
- peerDependencies: add the runtime-required @deepseek-ai/schemastery, and
the previously dangling meta entries @deepseek-ai/dsh-attachment and
@deepseek-ai/dsh-llm (optional, matching actual type-level use).
- prepack runs the full build; npm pack now yields exactly 7 files
(lib/index.mjs, lib/index.d.mts, lib/client.cjs, cordis.patch.yml,
README.md, LICENSE, package.json).
- publint clean: the client face ships as lib/client.cjs (CJS extension in
a type:module package); add lint:publint script. Built declarations pass a
NodeNext consumer typecheck (strict, skipLibCheck false).
Cordis contexts are fiber-owned: assigning onto an Object.create() overlay of
the apply-time context fails with 'cannot set property tools in multiple
fibers' when the reveal fires from the tools/result listener fiber (caught by
the e2e: the skill invocation matched but the suite never registered).
registerTools now tracks disposers through a plain closure over the captured
context — no context mutation anywhere. Also documents lazyTools in the
README and hardens the reveal against a failed registration (log and stay
hidden instead of latching).
Verified end to end against the real stack: first request carries 0 browser_*
schemas (skill catalog entry only); after the scripted skill invocation the
next request carries exactly the 11 browser_* tools and browser_session_start
dispatches for real.
Progressive disclosure, final stage: with lazyTools on (default), the eleven
browser_* tool schemas stay out of the system prompt — the browser-skill
catalog entry is the sole advertisement. One successful skill invocation
(model tool call via tools/result, or a /browser-skill user gesture via the
session append feed) registers the suite for the process lifetime, idempotent
on repeats; session resume is covered by scanning durable events for a past
tool/call+tool/result pair (or skill-invocation message) on session entry and
at apply time. lazyTools: false keeps the legacy always-on registration.
Investigation (recorded in the ticket): tools/result carries normalized
name/arguments with an isError discriminant; dsh 0.1 has no official global
visibility switch (ctx.tools.restrict is agent-scoped and throws from a plain
context), making conditional registration the intended pattern; per-step
assembly picks the new suite up on the next step, and visibility changes are
first-class inputs of tool-skill's catalog digest. registerTools now returns
the combined disposer via a prototype-preserving tracking overlay; the skill
prelude tells the model the browser_* tools unlock on skill load.
Tests: +8 (hidden-before/reveal/idempotent/gesture/history hit+miss/dispose/
scanner pairing/two-state apply wiring). 124/124 green.
The plugin exposed only tools; the BrowserSkill agent skill never reached
the harness's <available_skills> catalog. Register it as an embedded runtime
skill (progressive disclosure: catalog entry resident, body on skill-tool
invocation) via the official ctx.skills seam — silent no-op when the
composition lacks it.
Content is build-time assembled so there is one source of truth:
skill/prelude.md (committed, dsh-specific: tool<->CLI map, owned-session
semantics, plugin-only overrides) + the canonical repo-root skill/SKILL.md
verbatim (the same file crates/bsk-cli/build.rs mirrors; frontmatter
stripped, name/description supplied by the registration). Generated into
src/skill-content.generated.ts (gitignored) — registration and every
pre-step snapshot are pure in-memory reads: no disk, no process, no daemon.
Scripts: build:skill chained into build/test/typecheck (same pattern as
build:css); biome excludes the generated artifacts. Tests: +3 (catalog
content, in-memory weight, silent degradation). 116/116 green.
Blocking:
- B1: delete screenshot scratch PNGs — observation frames reuse one fixed
per-session path and unlink after every read (finally); browser_screenshot
unlinks once the bytes are in the attachment store (kept only when the file
itself is the model-facing artifact).
- B2: replicate dsh's browser-trust fence on /bsk-observation/*: loopback
Host only, Origin must match Host, sec-fetch-site: cross-site refused, POST
requires application/json; README documents the loopback trust premise and
the 0.0.0.0 warning.
Major:
- M1: KeyedExecutor tail chains previous+task (allSettled) so a task aborted
while queued cannot release the next one into the running session.
- M2: client tracks the live frame per session — replacing/removing/reset
revokes the old blob URL at once; loads settling after replacement never
resurrect it.
Minor: drop replaced thumbRefs (+on remove); beginAction fires inside the
queue (no label overwrite while queued, no idle flash); half-initialized
session cleanup stops through the queue with one retry; SSE (re)open refetches
/state (+ snapshot flag renamed subscribed); install probe uses --version (no
daemon spawn); emulate mobile documents the width+height requirement (the
daemon refuses it alone — verified).
Nit: single BskRunOptions declaration; tails map entry dropped on drain; SSE
cleanup on res close; popOut catches requestWindow rejections; resize handle
gains keyboard control (arrows, 16px steps, aria value attrs).
Tests: +14 (fence rules, scratch lifecycle, queue race, blob revocation,
instrumentation timing, SSE resync). 113/113 green.
The client entry imports the generated bsk-ui.nomodule.css; the file is
gitignored, so a fresh CI checkout could not resolve it. Generate it as part
of the test script.
The previous pass aligned the observation overlay with the dsh shell; the
product call is the opposite direction — the floating card should read as a
BrowserSkill surface, not a shell-native widget.
- Reuse @browser-skill/ui directly (Button, cn); status dots spec'd after the
extension popup's ConnectionStatusIndicator; Remix icons for
interrupt/pin/warn/pop-out.
- Compile the BSK tailwind utility sheet scoped under the .bsk-obs root class
(scripts/build-client-css.mjs + postcss-prefix-selector) and ship the oklch
design tokens on the same scope, so nothing leaks into the host shell and
the shell theme cannot bleed back. tsdown injects .nomodule.css verbatim
(minified, unhashed) alongside the hashed CSS modules.
- BSK ships no shared tooltip, so the one-time interrupt semantics hint is a
card-spec bubble (bg-card/border/12px radius), retired after first use.
- Tests: pin react/react-dom to this package's 18.x copies in vitest — the ui
package sources peer on react ^19 and would otherwise emit react-19
(transitional) elements that the react-18 renderer rejects. Production is
unaffected (react stays external, provided by the shell).
- stylelint: ignore the generated bsk-ui.nomodule.css.
The plain top:16 default overlapped the shell's Session log action;
dock the card and capsule at the content area's top-right (64px) so
neither collides with the header controls.
Review follow-ups: the card/capsule now default to the top-right (clear
of the composer), and the overlay reads as part of the shell instead of
a foreign widget:
- shared primitives everywhere: Button (outline/ghost sm) for
Interrupt/Pop out with the shell's danger hover token, Tooltip for
the one-time interrupt semantics hint (native span anchor — Button
does not forward refs), StateDot for status, and outline icons
(Stop/RightUp/ChevronDown/Warning) replacing text glyphs;
- every color/surface/shadow/label now uses --dsw-alias-* semantic
tokens (bg-overlay, border-l1/l2, state-*-primary, label-*,
interactive-bg-hover[-danger], brand-primary focus rings,
dsw-shadow-lv1/lv2) — no invented tokens, no literal colors (dsh 0.1
ships no spacing/radius scale; those stay px like dsh's own code);
- strip item focus ring uses brand-primary; focus-visible and
reduced-motion preserved.
A child killed via killFor (overlay interrupt) exits with a null code
and empty output, which used to render as a duplicated 'bsk x failed:
bsk x failed'. Report it as interrupted instead.
The session-authorized client RPC (readAttachment) refuses images that
no session log references — observation frames are plugin-owned runtime
data, so every overlay thumbnail failed with ATTACHMENT_NOT_REFERENCED.
The host now keeps the full attachment ref per frame and serves bytes
through GET /bsk-observation/thumbnail/<id> (verified readImage path);
the client loader is a plain fetch of that route.
