Subject: [PATCH 01/11] release: 0.4.0

Version bump across package.json, the lockfile, the plugin manifest, the
marketplace entry, and the npx pins in the agent skill.

Adds CHANGELOG.md covering what landed since 0.3.0: dispatched site
shortcuts, the Wikipedia shortcuts, proxy env var support, the loud exit 2
on a page with no readable content, and the MIT LICENSE file.

The skill gains a site shortcuts section, since 0.3.0 documented the
shortcuts in the README but the skill never mentioned them, plus the exit 2
contract and the proxy note. llms.txt gains Wikipedia and the proxy line.

README gains the end to end benchmark: five Wikipedia lookups run as whole
tasks in Claude Code with one tool each. All three tools answered every
task correctly, so it reports cost rather than accuracy.

+# Changelog
+
+Notable changes per release. Releases before 0.4.0 are listed at
+[github.com/only-cli/oc/releases](https://github.com/only-cli/oc/releases).
+
+## 0.4.0
+
+### Added
+
+- Site shortcuts are dispatched, not just documented. `oc <site> <verb> [args]`
+  resolves to a URL and then takes the same path `oc open` does, so it costs the
+  same and reads the same. A site is named by short name, bare name, or domain
+  (`oc hn`, `oc ycombinator`, `oc news.ycombinator.com`), the last argument
+  absorbs every word after it so a query needs no quoting, and `oc sites` lists
+  every site with its verbs. Shortcuts come from `clis/*.json`, so adding a site
+  is a JSON file and no code. (#19)
+- Wikipedia shortcuts: `oc wiki article <title>`, `oc wiki search <query>`, and
+  `oc wiki lang <code> <title>` for the other language editions. Articles are
+  read through `action=render`, which serves the article body without the site
+  chrome, navigation, and edit controls that surround `/wiki/<Title>`. (#22)
+- Outbound fetches honor `HTTP_PROXY`, `HTTPS_PROXY`, and `NO_PROXY`, including
+  the lowercase forms, so oc works in a sandbox whose only route out is a proxy.
+  HTTP and HTTPS proxies are supported and proxy credentials in the URL are
+  sent as `Proxy-Authorization`. (#17)
+- The MIT `LICENSE` file that the badge and `package.json` were already
+  claiming. (#18)
+
+### Changed
+
+- A page that distills to no readable text now fails loud instead of printing an
+  empty render and exiting 0. It writes one line to stderr and exits 2, which is
+  distinct from the exit 1 every other failure uses, so a caller can tell "this
+  page is empty" from "oc could not read this page" and fall back to a browser
+  only when that is worth doing. `--json` carries the same verdict as an `empty`
+  field. (#20)
+- The SSRF guard runs before a proxy is chosen, so a proxied request cannot be
+  used to reach an address the direct path would have refused. (#17)
+
+### Fixed
+
+- GitHub and Reddit shortcut URL templates corrected so their verbs reach the
+  pages they name. (#19)

+Read cost is one thing, but what an agent actually spends is another, so a
+second suite runs whole tasks end to end in Claude Code and compares `oc`
+against the tools the agent already has. Five Wikipedia lookups, one tool per

+| built-in `WebSearch` | 5/5 | 160,431 | $0.52 | 27 | 22s |
+
+All three got every answer right, so this is a cost result, not an accuracy one.
+Input tokens are the fresh context each tool put in front of the model, which is
+the number the page size drives; totals including cache reads sit closer together
+because the agent's own prompt dominates them. The spread widens with the page:
+`oc` cost 5.7x less than `WebFetch` on a short stub and 35x less on a long
+article, because the 500 token budget makes it flat at about 1,100 tokens per
+page while a full fetch pays for whatever the page weighs. `WebSearch` was given
+only the question, not the article URL, which is the honest way to use it and
+part of why it costs the most.

 ## Status
 
 Early. Reading works and is covered by offline tests: static pages, XML feeds, JSON APIs, budget-aware rendering, sessions, and the numbered actions `do`, `find`, `read`, `next`, and `raw`. Writing does not: `fill`, `submit`, and `back` report that they are not implemented rather than pretending, and a lazy headless fallback for script-heavy pages comes after them.

Subject: [PATCH 02/11] docs: document the proxy support that shipped in #17

The feature landed with one sentence in the install paragraph, which named
the three environment variables and nothing else. Anyone actually putting oc
behind a corporate proxy had to read src/fetch.js to learn that an https
target prefers HTTPS_PROXY and falls back to HTTP_PROXY while an http target
uses HTTP_PROXY only, that a bare host:port is read as http://, that a socks
URL is refused rather than ignored, or that NO_PROXY takes suffix, wildcard,
host:port, and CIDR entries. All of that is now in a Proxies section, and
every claim in it was checked against the merged code rather than written
from the diff.

Two limits are documented instead of left to be discovered. oc does not read
ALL_PROXY, but the impers transport is libcurl underneath and reads it on its
own, so a request oc treats as direct can still leave through a proxy; the
same holds for the *.suffix, host:port, and CIDR forms of NO_PROXY, which
libcurl does not parse. Verified live against a third party proxy by watching
the egress IP: with only ALL_PROXY set, or with NO_PROXY=*.host naming the
target, oc reported a direct fetch and the request went through the proxy
anyway. And an IPv6 literal over HTTPS cannot work through a proxy today,
because URL.hostname keeps the brackets, so net.isIP reads 0 and the SNI and
certificate check both treat [2606:...] as a DNS name.

The security properties a reader would otherwise have to assume are stated:
the CONNECT tunnel still verifies the origin certificate (confirmed against
expired, self-signed, and wrong-host endpoints through a real proxy),
credentials in the proxy URL reach the proxy and nothing else including
across redirects, private and internal targets stay refused, and a name that
resolves publicly for oc and internally for the proxy is not something oc
can detect, so the proxy is trusted for its own egress policy.

The skill gets the short version, since an agent needs two things: that no
flag or setup is required, and that a "proxy failed" or "blocked" line is a
transport problem to report rather than a page to retry. llms.txt gets one
fact next to the existing transport fact.

+Requires Node 20+. Requests impersonate Chrome via [impers](https://github.com/lexiforest/impers); falls back to native fetch if impers is unavailable.
+
+### Proxies
+
+Outbound fetches honor the usual environment variables, in upper or lower case, with nothing to pass on the command line:
+
+```
+HTTP_PROXY=http://proxy.example:8080       # http:// targets
+HTTPS_PROXY=http://proxy.example:8080      # https:// targets, tunneled with CONNECT
+NO_PROXY=internal.example,*.corp.example   # reached directly instead
+```
+
+An `https://` target prefers `HTTPS_PROXY` and falls back to `HTTP_PROXY`; an `http://` target uses `HTTP_PROXY` only. A value with no scheme is read as `http://`, so `proxy.example:8080` works. Only HTTP and HTTPS proxies are supported, and another scheme such as `socks5://` is refused by name rather than silently ignored.
+
+Credentials in the proxy URL are sent as `Proxy-Authorization` to the proxy and to nothing else, including across redirects:
+
+```
+HTTPS_PROXY=http://user:pass@proxy.example:8080 oc open https://example.com
+```
+
+`NO_PROXY` accepts an exact host, a `.suffix` or `*.suffix` pattern, a `host:port` entry, a CIDR block, and `*` for everything.
+
+An `https://` page is tunneled with CONNECT and its certificate is verified the same way it would be without a proxy, so a proxy in the path cannot read or rewrite the page.
+
+Two limits are worth knowing:
+
+- oc does not read `ALL_PROXY`. The impers transport is libcurl underneath and reads it on its own, so a request oc treats as direct can still leave through an `ALL_PROXY`. The same holds for the `*.suffix`, `host:port`, and CIDR forms of `NO_PROXY`, which libcurl does not parse. Set `HTTP_PROXY` and `HTTPS_PROXY` explicitly and keep `NO_PROXY` to plain host and suffix entries when the two need to agree.
+- An IPv6 literal target over HTTPS does not currently work through a proxy.
+
+Private and internal addresses are refused whether or not a proxy is set. With a proxy configured, a hostname that does not resolve locally is refused too, because the proxy would otherwise resolve it on a network oc cannot see. A name that resolves publicly for oc and internally for the proxy (split horizon DNS) is not something oc can detect, so a proxy is trusted to enforce its own egress policy.

Subject: [PATCH 03/11] ci: make a stable release refresh the skills.sh page

skills.sh renders skills/web-browsing-cli/SKILL.md straight from GitHub, and
the release checklist said there was nothing to do for it because the skills
CLI reads that file live off main. That is true of the install path and false
of the page: the page showed the 0.2.0 pin from 2026-08-20 while main had
already shipped 0.3.0 and 0.4.0 the same day, so every reader was handed a
two-release-old install command.

The site offers exactly one lever. Its documented API is read only, with no
refresh or re-index endpoint, and the skills CLI has no publish or sync
command; a repository is re-read after the telemetry service sees an install
from it, and repo pages are cached on top of that. So a stable publish now
runs one `skills add` against the repo, which is the invocation the
install-remove-loop experiment already proved out. It costs one install on the
counter per release, which is the price of the only mechanism there is. The
job is continue-on-error and runs after npm publish has already succeeded: a
page that catches up late is a smaller problem than a red release.

The refresh is worthless if the pin it publishes is stale, which is the actual
root cause here, so a latest publish now fails when SKILL.md disagrees with
package.json. Beta and dev skip the check, because a pin moves when a release
is stable rather than when it enters beta, which is the rule 0.3.0-beta.1
already followed. Verified both ways against the current tree: it passes on
0.4.0 with a matching pin and refuses a 0.4.0 release still pinning 0.2.0.

The channel the earlier step resolves is now a job output, so the refresh job
can gate on it instead of re-deriving it from the version string.

Stack Overflow search goes through the Stack Exchange API, and each result prints its `question_id`: read one with the `question <id>` feed rather than following its link, since the question page itself answers a bot challenge instead of the question.

Subject: [PATCH 06/11] give cli.js the exec bit

package.json points bin.oc at src/cli.js, so an npm link resolves the
global oc to this file directly and running it needs the bit. Without
it every oc invocation dies with Permission denied while node src/cli.js
keeps working, which is easy to miss.

Subject: [PATCH 07/11] chore: resolve the Scorecard alerts a repo change can
 fix

Every GitHub action is now pinned to a full commit SHA with its version
in a trailing comment, verified against each upstream repo's tags, so a
retagged release cannot swap code under CI. The publish workflow pins
npm to an exact version instead of @latest, the experiment Dockerfile
pins its base image by digest, and codeql.yml gets a top-level read-all
permissions block so the default token grants nothing the analyze job
does not ask for.

SECURITY.md points reports at GitHub private vulnerability reporting,
which is now enabled, and scopes out experiments/. Branch protection on
main now blocks force pushes and deletions.

+## Reporting a vulnerability
+
+Report vulnerabilities privately through GitHub: [Security > Report a
+vulnerability](https://github.com/only-cli/oc/security/advisories/new).
+Please do not open a public issue for anything exploitable.
+
+Expect an acknowledgement within a week. Fixes ship as a patch release,
+and the advisory is published once the fix is out.
+
+## Scope
+
+oc fetches untrusted web pages by design, so the interesting bugs are the
+ones where page content escapes its role as data: rendered text that can
+alter what an agent executes, URLs that reach private or internal hosts
+despite the SSRF guard, or a crafted page that breaks the distiller. Bugs
+in the experiments/ directory are out of scope; nothing there ships in
+the package.
+
+## Supported versions
+
+Only the latest release on npm is supported. There is no backporting; a
+security fix means a new release.

Subject: [PATCH 08/11] chore: drop the npm self-upgrade from the publish
 workflow

Node 24 has bundled an npm new enough for trusted publishing since
24.4, so upgrading npm at publish time only added an unpinned install
to the release path. If a runner ever serves an older 24.x, npm publish
fails loudly rather than shipping anything.

Subject: [PATCH 09/11] fix: bound response bodies before buffering them

Both transports buffered a text response whole before the distiller saw
it, so a hostile URL was an unbounded allocation. Every transport now
enforces one cap, 25MB decoded, three times the largest body oc fetches
on purpose. Content-Length is checked first to fail before the bytes
arrive, and because that header is optional and untrusted, the stream
is counted as it lands too: native fetch and the proxy transport abort
the transfer at the cap, and impers, which buffers inside its own
binding, is checked before its body travels any further. Decoded bytes
are what get counted, which is what stops a decompression bomb.

Fixes #27

Subject: [PATCH 10/11] fix: judge an unreadable page by evidence, not by
 length alone

contentFailure called every render under 25 tokens a failure, which
made exit 2 claim a terse page was JavaScript-only, gated, or
challenged when it had simply arrived terse. The verdict now needs
evidence: nothing extracted is empty whatever the page weighed, and a
short render is only a failure when the markup behind it was far too
big to have carried only that. A status endpoint or a one-line answer
now exits 0, script-only shells and consent walls still exit 2, and
raw applies the same rule before refusing. The --json empty field
follows the same policy, so callers keep a machine-stable distinction
between empty and merely short.

Fixes #29

Subject: [PATCH 11/11] fix: cap page-written scalars at the render boundary

The title and every heading are the page's to write, and both skipped
truncate(), so one hostile scalar could print unbounded output whatever
the budget said. The compact view now cuts titles, headings, and input
names at the same cap and marker every other block gets, and read cuts
even a first block bigger than its whole budget, since 'up to N tokens'
is a promise the page must not be able to break. The distilled page
keeps the full values: --json stays the machine-stable view, bounded by
the fetch cap, and machines cut for themselves.
