Agents cannot be named in CJK or Cyrillic: slugify is ASCII (tsk-3qp7e6) - #2798
Merged
Conversation
… (tsk-3qp7e6)
`slugify_agent_name` matched `[^a-z0-9]+`, so every non-ASCII code point was
deleted BEFORE `validate_agent_name` checked whether anything was left. A name
written entirely in Chinese, Japanese, Korean, Cyrillic, Greek, Arabic, Hebrew
or Thai therefore came back as "Agent name must contain at least one letter or
number" -- the agent could not be created at all. Accented Latin survived but
lost its accents rather than folding them ("naive resume" spelled with accents
slugged to "na-ve-r-sum").
`agent_registry_store._slugify` papered over the empty result with a constant
`or "agent"`, which is the worse half: every unslugifiable name got the SAME
slug, so agents registered close together shared one identity prefix in the one
table that exists to hold distinct identities. `lib/slug.ts` had no fallback at
all, so the deploy/import wizards showed an empty derived slug with nothing to
explain it, and `ConsentActions` carried a divergent inline copy whose
`|| "project"` had the same collision.
Python now has one slug implementation: `slugify_agent_name` transliterates via
python-slugify, and `_slugify` delegates to it. Where a slug is mandatory,
`agent_slug_or_fallback` supplies a per-name `agent-<blake2s>` -- deliberately
not a constant, so two names that survive nothing still get two identities.
Transliteration also closes a homoglyph gap: a Cyrillic spelling of "user" now
resolves to `user` and is rejected by the reserved-prefix guard instead of
vanishing to "".
The desktop copies collapse into `lib/slug.ts`. The client folds combining
marks (so accents match the server) but does not transliterate -- that needs a
character table, and inventing a client slug the server will not mint is worse
than admitting there is none. `slugifyWithFallback` covers callers that must
send something; the wizards say why the preview is empty instead of showing a
bare em dash.
python-slugify depends on text-unidecode (Artistic-1.0 OR GPL-2.0-or-later); we
elect the Artistic arm, recorded in docs/dependency-licences.md. The
`python-slugify[unidecode]` extra pulls GPL-only Unidecode and is a blocker for
the commercial licence, so a test asserts it never enters pyproject or uv.lock.
Also fixes `unique_agent_slug` appending `-N` to an already-63-char slug, which
overran the container-name limit the truncation exists to respect.
Slugs are re-derived at creation time only; existing rows keep their identity.

The test registers two different slugs, so the assertions do not exercise the collision suffix. It also does not force both registrations to use the same timestamp. Freeze or patch the clock and use the same slug, or rename the test to match the behavior it verifies.

- Around line 365-370: Update the empty-slug hint condition in ImportWizard so
it is shown only when the server accepts the agent name and derives a non-empty
slug; suppress it for names rejected by validate_agent_name, including emoji- or
punctuation-only names. Reuse the existing slug/name validation logic rather
than presenting the hint whenever slug is falsy.
In `@tinyagentos/agent_registry_store.py`:
- Line 432: Update the fallback digest generation in the agent slugging logic to
use a substantially larger digest size, and ensure fallback slug lookup cannot
silently map a colliding digest to the wrong raw name. Preserve canonical-ID
uniqueness and reject or disambiguate any fallback slug already associated with
a different name; locate the surrounding slug-generation and get_by_slug logic
in agent_registry_store.py.
In `@tinyagentos/routes/project_invites.py`:
- Line 124: Update the handle construction around agent_slug_or_fallback so the
harness-derived base is computed first, then append the slugified label when
present; do not let a label-only value bypass the harness fallback. Preserve the
existing separator and fallback behavior for missing labels.

Docs-Reviewed: merge only, no new installer behavior introduced by this branch
…k bug, document the ß/ligature slug gap
- CodeRabbit: agent_slug_or_fallback's blake2s digest was only 4 bytes (32-bit
collision space); get_by_slug() resolves a slug to the oldest matching
record, so two colliding unslugifiable names could resolve a lookup to the
wrong agent. Widened to 8 bytes.
- CodeRabbit: _derive_os_handle dropped the harness component when the
display name was unslugifiable but the label slugified successfully, since
the joined string was non-empty and skipped the trailing harness-fallback
' or '. Two different harnesses could then collide on the same label-only
handle. The harness fallback now applies as soon as the alias-derived base
is empty, not just when the whole joined string is.
- kilo-code-bot: slugifyClient's docstring overstated its accent coverage --
letters with no NFKD decomposition ("ß", "ŋ", "ɐ") are not combining
marks and are dropped rather than transliterated, unlike the server
(python-slugify). Documented the gap and pinned the known mismatch in a
test rather than silently regressing it; a client-side transliteration
table was judged out of scope for the same reason CJK/Cyrillic already are.
Docs-Reviewed: internal bug fixes to already-documented behavior (handle/slug
derivation), no route contract or agent-facing semantics changed -- the
project-invite redeem response shape and inputs are unchanged, only the
derived handle value for a narrow input case
…oy/Import wizards CodeRabbit: /api/agents/deploy and /api/agents/import both call validate_agent_name + unique_agent_slug, which REJECTS a name whose slug is empty (pure emoji/punctuation) -- unlike the agent-registry flow, they have no server-side fallback. Both wizards' hint claimed 'taOS derives the slug for you' for exactly that case, which is false: submitting gets a 400 'Agent name must contain at least one letter or number'. Reworded to point at the manual edit control instead of promising a fallback that does not exist on these two routes. Docs-Reviewed: UI copy fix only, no route/behavior change

TestAgentSlugOrFallback was inserted in the middle of TestSlugify, putting test_leading_trailing_dashes and test_multiple_spaces inside the wrong class and breaking their TestSlugify.<name> symbol resolution. Moved TestAgentSlugOrFallback to after TestSlugify's last method so both classes are whole again.

CARD TITLE (intent, not commit subject): [lib-audit] Agents cannot be named in CJK or Cyrillic: slugify is ASCII
