What

Two fixes found while testing the CLI end to end against the development cloud on 2026-09-11. Each fix has a check that fails when the fix is reverted.

1. Stop telling people to use a retired model id

After installing the 0.5.6 nightly, the installer printed wally opencode --cloud -m glm-5.3. glm-5.3 is retired, and the gateway refuses it with 403 model_not_entitled. The entitled set is glm-5.3-flash, qwen3.8-27b and gemma-4. The same id was in skills/runanywhere/SKILL.md, which the installer copies into coding agents' skill folders.

  • install.sh and skills/runanywhere/SKILL.md now say glm-5.3-flash.
  • New scripts/ci/check-retired-model-ids.py, with tests in tests/test_retired_model_ids.py, both run in CI. It fails on glm-5.3, glm-5.2 or gemini-2.5-flash in the installers, READMEs, docs/, the skill folders or src/. The retired list matches infra's contracts/public/status_semantics.json.
  • Break test: putting glm-5.3 back makes the check exit 1 and name both lines; with the fix restored it is green.

2. install.sh runs under POSIX sh

The documented install is curl -fsSL .../install.sh | sh, but the script used set -o pipefail, [[ ]] and ${var:0:16}. Under dash, which is sh on Debian and Ubuntu, it stopped on line 2 with set: Illegal option -o pipefail before printing anything.

  • Changes: POSIX sh throughout: set -eu, [ ], and printf '%.16s'. The release lookup now downloads first and parses second.
  • Offline comparison: fake curl and uname, a local tarball, and no network. Of 14 cases (flags including nightly/--nightly, both platforms, unsupported platform, bad checksum, version mismatch), 12 are byte-identical under bash, dash and /bin/sh.
  • The one behaviour change: a failed release lookup, or a missing tag_name, still exits 1 but now also prints its error message. pipefail used to swallow it.
  • CI: sh -n, dash -n and shellcheck -s sh, plus the existing scripts/test/test-install-skill-dirs.sh under dash (nothing ran it before).
  • Break test: with pipefail and one [[ ]] put back, shellcheck fails (SC3040, SC3010) and the dash run fails all 4 cases. Restored, everything passes.

Found, not changed here

  • Usage attribution. Traffic from wally claude-code is recorded as harness unknown. The translator in src/anthropic/messages.cpp sends cpp-httplib's default User-Agent, and the control plane detects Claude Code only by a User-Agent containing claude-code. Proposed fix: set User-Agent: wally/<version> claude-code on both clients in the translator. Do not send X-RA-Harness: the API only accepts console, playground, rcli and sdk as declared values, and a declared rcli would mislabel the traffic. Not committed because the translator can't be built without the SDK kit here.
  • wally codex fails against the cloud. It uses the Responses API, which the gateway refuses today; infra #339 is open.
  • Nightly and production installs share ~/.local/lib/wally and the profile directory, so installing one replaces the other, and a saved dev console_url keeps a production binary on api-dev until logout.
  • The packaged binary links Homebrew openssl@3 dylibs that the bundle doesn't include (seen with otool -L).
  • SKILL.md still says opencode is the only harness.

No release label: merging this should not cut a release by itself.

…on a retired id

The gateway refuses glm-5.3 with 403 model_not_entitled; the hosted models
today are glm-5.3-flash, qwen3.8-27b and gemma-4. Two places still told people
to type the retired id:

- install.sh's "Next:" block printed `wally opencode --cloud -m glm-5.3`
  (seen live installing the 0.5.6 nightly on 2026-09-11), so the first command
  a new user copies fails.
- skills/runanywhere/SKILL.md used the same id, and the installer copies that
  skill into ~/.claude/skills and ~/.agents/skills, so an agent following it
  hits the same 403.

Both now say glm-5.3-flash; the "Next:" columns are re-aligned for the longer
id. README.md already used glm-5.3-flash. install.ps1, docs/ and src/ help
text carried no retired id. tests/ fixtures that use glm-5.3 as an arbitrary id
(config builders, a fake console's usage history) are left alone: they assert
nothing a user reads.

There is no single declared source for hosted model ids in this repo
(cmd_default_models.cpp and preferences hold no hosted id; README.md names them
in prose), so the guard is a denylist:
scripts/ci/check-retired-model-ids.py holds RETIRED, mirroring
launch_models.retired in InferenceInfra's contracts/public/status_semantics.json
(glm-5.3, glm-5.2, gemini-2.5-flash), and scans install.sh, install.ps1, the
READMEs, docs/, skills/, .claude/skills, .agents/skills and src/. It matches
whole ids only, so glm-5.3-flash does not trip it. tests/test_retired_model_ids.py
covers the matcher and the repo scan. Both run in ci.yml's distribution job.

Break test (reintroduce glm-5.3 in install.sh and SKILL.md, then restore):

  fixed tree:
    Ran 6 tests in 0.056s
    OK
    no retired model ids in 117 user-facing files
    exit=0

  glm-5.3 put back (sed 's/-m glm-5\.3-flash/-m glm-5.3/'):
    install.sh:206: retired model id 'glm-5.3'
    skills/runanywhere/SKILL.md:54: retired model id 'glm-5.3'
    2 retired model id(s) in user-facing text; the gateway refuses these with 403 model_not_entitled.

install.sh is documented and served as `curl -fsSL .../install.sh | sh`, but
it was a bash script: `set -euo pipefail`, `[[ ]]` in five places, and a
`${expected_sha:0:16}` substring. On Debian and Ubuntu sh is dash, which dies on
line 2 before printing anything:

  $ dash install.sh
  install.sh: 2: set: Illegal option -o pipefail     (exit 2)

Changes, all to syntax the script already meant:
- shebang #!/bin/sh, `set -eu`
- `[[ a ]]` -> `[ a ]`; `[[ ! -t 0 || ! -t 1 ]]` -> `[ ! -t 0 ] || [ ! -t 1 ]`
- `${expected_sha:0:16}` -> `$(printf '%.16s' "$expected_sha")`
- the release lookup fetches first and pipes second, so a failed curl reaches
  fail() without needing pipefail
- a shellcheck directive on the PATH line that is written to the rc file
  literally on purpose (SC2016)

Flags (nightly, --nightly, --print-skill-dirs), install paths, asset names,
the checksum verification and the output are unchanged. Verified offline with
a stub harness (curl and uname stubbed first on PATH, a local fake release
tarball holding a fake wally, throwaway HOME, proxy pointed at a dead port so
nothing can reach the network). 14 cases: macOS arm64, nightly and --nightly,
Linux x86_64 and amd64, Intel Mac, Linux aarch64 and FreeBSD refused, bad
checksum, installed-version skew, release API down, release without tag_name,
--print-skill-dirs, both agent homes. The new script under bash, dash and
macOS /bin/sh was diffed against the old script under bash (sha hex masked,
since the fake tarball's mtime changes every run):

  12 of 14 cases byte-identical under all three shells: stdout/stderr,
  exit code, every curl URL requested, every file written under HOME.

  api-down and no-tag: same exit 1, plus one line the old script meant to print
  and never could:
    > error: Could not determine latest release version. Check your internet connection.
  Under pipefail a failed curl, or a release body with no tag_name, failed the
  VERSION=$(...) assignment and set -e exited silently at "[1/5] Resolving the
  latest release". That fail() was unreachable before. It is the only
  behaviour change.

The old script under dash failed all 14 cases with exit 2 at line 2.

CI: ci.yml's distribution job ran `bash -n install.sh`, which cannot fail on
any of this: `[[` parses as a command name and pipefail only fails at run time.
install.sh now gets its own step: sh -n, dash -n, `shellcheck -s sh`, and
scripts/test/test-install-skill-dirs.sh run with WALLY_INSTALL_SH=dash. That
test existed but nothing ran it; it now takes the shell from WALLY_INSTALL_SH
(default sh, as before). shellcheck is installed if the runner lacks it.

Break test (put `set -euo pipefail` and one `[[ -x ... ]]` back, then restore):

  fixed tree:
    $ sh -n install.sh                       exit=0
    $ dash -n install.sh                     exit=0
    $ shellcheck -s sh install.sh            exit=0
    $ WALLY_INSTALL_SH=dash bash scripts/test/test-install-skill-dirs.sh
    ok   claude-only
    ok   agents-only
    ok   both
    ok   neither-defaults-claude
    all skill-dir cases pass                 exit=0

  bashisms restored:
    $ sh -n install.sh                       exit=0   (parse-only cannot bite)
    $ dash -n install.sh                     exit=0   (parse-only cannot bite)
    $ shellcheck -s sh install.sh
    In install.sh line 6:
    set -euo pipefail
             ^------^ SC3040 (warning): In POSIX sh, set option pipefail is undefined.
    In install.sh line 123:
    [[ -x "${staged}/bin/wally" ]] || fail "Archive did not contain bin/wally as expected."
    ^----------------------------^ SC3010 (warning): In POSIX sh, [[ ]] is undefined.
                                             exit=1
    $ WALLY_INSTALL_SH=dash bash scripts/test/test-install-skill-dirs.sh
    .../install.sh: 6: set: Illegal option -o pipefail
    FAIL claude-only
    FAIL agents-only
    FAIL both
    FAIL neither-defaults-claude
    4 test(s) failed                         exit=1

  restored (cmp against the fixed copy: identical):
    sh -n 0, dash -n 0, shellcheck -s sh 0, skill-dirs under dash: all pass, 0

Not verified: the workflow step itself (actionlint is not installed locally;
ci.yml parses as YAML), and a real download of a published release.

CI can accept identical but incorrect installer behavior, and syntax errors in tap-update tooling can evade validation. These are bounded CI coverage gaps worth fixing before relying on the new checks.

Run bash -n once for each script.

Bash parses only the first script path. scripts/release/update-tap.sh becomes an argument to scripts/build/package-wally.sh, so syntax errors in the second script can bypass this check.

Assert each fixture’s expected result.

The check calls compare only the normalized bash_out, dash_out, and sh_out values. All shells can return the same incorrect status or output and pass. Assert the expected exit status and output for each fixture. Add a successful curl response without tag_name and assert the lookup error; no reachable test currently covers this path.
