Every portal CLI turned HTML into text with a bare tag strip, so the
text inside comments, <style>/<script> blocks and hidden or
display:none elements came out as visible text. Unicode tag
characters, bidi controls and zero-width characters passed through
untouched, raw from the portal's JSON or decoded from numeric
entities. A listing could carry an instruction that renders as nothing
on the page but reads as text to the model.
Each CLI now runs HTML through visibleHtml, extending the helper
jobindex already used for one of its page shapes, and strips invisible
characters at the one function every output format reads. The
/add-portal contract names both, with linkedin-search as the copy
source.
Each CLI's tests/hidden-text.test.ts drives the real path (the CLI in
a fresh process, the command handler, or the normalizer the handler
calls) and fails on master.

/apply and /rank state that postings are untrusted third-party data,
never instructions. Ten other specs that fetch or read such content did
not: /scrape ingested portal CLI output and WebSearch results with no
rule, /gmail-sync classified inbound email - the input anyone can send -
with none, and /setup Path A read the verbatim archived posting and
email-quoting outcome notes and wrote calibration into
04-job-evaluation.md, which every later /apply and /rank loads.
Each spec now points at the Trust boundary section of 09-web-research.md
instead of copying it. /gmail-sync gains Important Rule 10 (no link
fetched, no attachment opened, no reply, draft, label or forward), and
/setup Step A3 never copies archive wording into a skill file.
The new test derives the set of specs from the tools they call, so a
future fetching command without the rule fails CI. On master it lists
all ten.

* security(skills): drop bare Bash and the portal CLI glob from skill grants
A skill's allowed-tools pre-approves the listed tools for the turn that
invokes it, even in an untrusted folder. job-application-assistant granted
bare Bash, Edit and Write; job-scraper granted bun run on any
.agents/skills/*/cli/src/cli.ts. Every Bash command the skills document is
already allowlisted per command in .claude/settings.json, so the bare and
glob grants bought nothing but exposure. The per-portal grants stay in
settings.json, which is where a portal added by /add-portal registers too
(Step 5 now says so).

* security(settings): deny exfil-shaped shell and credential reads, always ask on permission-defining files
Deny rules block in every permission mode including bypassPermissions and
override any allow rule or skill grant; ask rules force a prompt even when
a skill's allowed-tools would pre-approve the call. settings.json now
ships both: deny for shell that uploads or opens a remote shell (curl
data/form/upload flags, wget post, scp, sftp, ssh, nc) and for reads of
.env and ~/.ssh, ~/.aws, ~/.gnupg; ask for the files whose content is the
permission surface (settings, skill frontmatter, agents, CI, this guard)
and for git push. security_guards.py requires each rule to stay present,
the same way it requires the personal-data gitignore rules. Prefix rules
are tripwires, not walls; SECURITY.md will say so.
Also allowlists tools/robots_check.py and the upcoming tools/fetch_page.py
so the 403 retry no longer needs a curl grant.

* security(guards): hold skill and command allowed-tools to a reviewed allowlist
The guard allowlisted settings.json permissions but never read skill
frontmatter, so the narrow settings allowlist sat next to a bare Bash
grant it could not see. Check 4 parses every .claude/skills/*/SKILL.md,
.agents/skills/*/SKILL.md and .claude/commands/*.md frontmatter with a
stdlib parser (scalar, folded, and list forms) and holds each
allowed-tools entry to ALLOWED_SKILL_TOOLS; a portal skill may
additionally grant exactly its own cli/src/cli.ts, matched by path so no
portal name is hardcoded. Bare Bash and mid-pattern wildcards get their
own message. On master's frontmatter this check reports two failures.

* feat(tools): add GET-only fetch_page.py for the browser-header retry
09-web-research.md documented the 403 retry as a curl command with browser
headers plus an inline python3 -c tag-stripper, which meant the workflow
wanted a Bash(curl:*) grant - and curl with a free tail is an upload
channel. fetch_page.py is the same retry as one command with a fixed GET
argv (URL after --, bounded to 45 s / 5 redirects / 10 MB), http(s) only,
robots_check.gate() enforced with no bypass flag, --out refused inside
the repo, and --text for the stripped page. urllib fallback when curl is
absent. The settings.json grant names the script.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
* docs(security): describe the permission surface as a table; route the 403 retry through fetch_page.py
SECURITY.md now lists every shipped grant with its location, lifetime
and guard, and says plainly what the permission layer does not do: no
sandbox on native Windows, prefix rules are tripwires, WebFetch is
unrestricted by domain, subagents run with the parent's tools (next
change), and Edit/Write stay granted because tailoring a CV is editing
files. 09-web-research.md's retry section is the one fetch_page.py
command (framework_version 1.1.3 -> 1.1.4); apply, rank and scrape point
at it instead of curl. SETUP.md and the README tools tree follow.
CHANGELOG gains a Security section under [Unreleased].

* security(review): ask on command frontmatter, portal skills grant only their CLI, bound the urllib fallback
Findings from a fresh-context review of the branch:
- A command's frontmatter is a grant too (check 4 already parses it), so
Edit(.claude/commands/*.md) joins the required ask rules; without it a
steered session could write `allowed-tools: Bash` into apply.md with no
prompt and the next /apply would be pre-approved for bare Bash.
- SECURITY.md promised a portal skill may grant "its own CLI and nothing
else"; the guard now enforces exactly that instead of own-CLI plus the
core allowlist. All six shipped portal skills already comply.
- fetch_page.py's urllib fallback now matches curl's 5-redirect cap and
applies the 10 MB cap after decompression, so the docstring's bounds
hold on both paths.
- Frontmatter parser: a BOM no longer reads as "missing frontmatter",
YAML flow lists split correctly, and a non-UTF-8 file fails with a
message instead of a traceback. Module docstring lists check 4.
- CHANGELOG no longer claims "no new prompt": compile and aux cleanup,
which the removed bare Bash covered in a skill-invoking turn, now
prompt, deliberately. "Once per session" wording corrected to per call.
- Three upload-shaped deny siblings added (curl -XPOST, curl --request
POST, wget --method=POST); /add-portal recon points at fetch_page.py.

The contract's Fetching line still said "browser User-Agent", predating the
honest-UA posture (#283/#277). It now names the shipped convention and routes
browser-header escalation through the 09-web-research robots gate.
Also moves #304's CHANGELOG entry out of the released 1.4.0 section - the
branch predated the release cut, so the three-way merge landed it there -
into [Unreleased]/Changed where it belongs.

* docs(add-portal): specify credential handling for portals needing an API token
/add-portal can already scaffold a skill for a portal that returns usable
content only through a paid fetching service, but the spec says nothing
about the credential such a skill needs: no guidance on where it lives, no
requirement to document it, no defined failure mode when it is unset, and
no point at which the user learns the portal costs money per query.
Three additions, all to the generator spec:
- Step 2 gains a reconnaissance point for whether the portal needs a
credential at all, to be raised with the user before scaffolding. A
portal that bills per query is a different proposition from a free one
and the user should get to decline it.
- The portal-skill contract gains a Credentials rule: environment variable
only, named <SERVICE>_API_TOKEN, never a CLI flag (flags leak into shell
history and process listings), never in url-reference.md or a fixture,
and a MISSING_CREDENTIALS exit rather than a fallthrough to an
unauthenticated request that fails confusingly.
- SKILL.md for such a skill must carry a Setup section naming the service,
the variable, and the per-call billing.
Spec only. All six shipped portals are free and unauthenticated, so no
existing skill changes and the zero-dependency default is untouched.
Evidence this is not speculative: running /add-portal against portals that
sit behind bot-detection produced four token-requiring skills in my own
fork (Bright Data Web Unlocker), each of which had to invent its own
convention for reading, documenting, and failing on the token, because the
spec defines none.
Verified: lint_skills, check_framework_version, security_guards all OK;
python3 -m unittest discover -s tests 196 passed.

* docs(add-portal): subordinate the credential check to the robots.txt decision
Review catch: as written, Step 2.5 could be read as "robots.txt or the
terms said no, but a paid unlocker gets through, so here is the convention
for that" - which would let a paid fetcher launder a robots refusal.
That is not the intent and it contradicts the posture settled in #277/#286
(09-web-research.md, tools/robots_check.py): robots.txt is decided first
and honestly, and is never overridden by better fetching machinery.
State the subordination explicitly in 2.5 rather than leaving it implied by
step order, and record it in the changelog entry so the constraint survives
later edits to the step. The credential path is for portals whose robots.txt
permits access but whose bot protection blocks ordinary fetches - paying for
access a site allows, never paying past a site's no.
Wording follows the reviewer's suggestion.
Verified: lint_skills, check_framework_version, security_guards all OK;
python3 -m unittest discover -s tests 219 passed.

The cli-checks matrix hardcoded the six shipped portals, so a CLI
scaffolded by /add-portal in a fork shipped typecheck and test scripts
that fork CI never ran - while security_guards.py already globs
.agents/**/package.json and covers new portals automatically. A
discover-clis job now emits the matrix from
.agents/skills/*/cli/package.json; on upstream it resolves to the same
six portals, and a fork-added portal joins the matrix with no workflow
edit. /add-portal's Register step now says so.
The README has always invited users outside Denmark to build equivalents of
the four Danish portal CLI skills, but doing so meant reverse-engineering
.agents/skills/*/cli/ by hand. /add-portal turns that invitation into a
guided workflow:
- Interviews the user for the portal URL, skill name, market/language
(trigger phrases in the local language, like the Danish skills), and a
realistic test query
- Investigates the portal before writing code: search-URL pattern, result
structure (JSON API preferred over HTML), detail-page pattern, robots.txt
and access rules. Auth-walled portals are declined; portals with
restrictive terms get a prominent personal-use-only warning in the
generated SKILL.md (same as linkedin-search)
- Scaffolds from the canonical structure with linkedin-search as the
zero-dependency reference, enforcing the shared portal-skill contract:
search/detail commands, common flags, {meta, results} JSON shape, stderr
JSON errors, backoff on 429/5xx, chunked parsing
- Mandatory live test-run (search + detail + test suite) before registering
- Optionally wires the portal into /scrape via search-queries.md
The generator is country-agnostic; its output is market-specific and stays
in the user's fork, matching the repo policy that upstream remains a
universal template.
Docs: README (commands list, file structure, Job search tools section) and
SETUP.md (CLI install section pointer).
