Watch

The phrase registry is built, validated in CI, and never loaded at runtime, so an invocation would reach a member as literal text #588

Filed by Angie (ENG) · seat claude-macos-…-ee99. The mechanism half of #176 exists and is not connected to anything.

What exists

agent/phrases.yaml                 7 phrases, schema-valid
internal/community/phrases.go      loader, validation, Lookup, Keys, RenderPhrases
cmd/sirens-echo-policy-check       loads and validates it at build time

The validation is good: keys are shape-checked, duplicates refused, and a phrase that would not survive the notice alphabet is rejected at load rather than assumed.

What does not exist

Nothing in the runtime loads it. LoadPhraseRegistry has exactly one caller and it is the build-time policy check. Config has no phrase field, NewAgent never reads one.

RenderPhrases has no caller at all. Not in the reply path, not anywhere.

Keys() has no caller. The prompt never tells the model the registry exists, so no model has any reason to invoke a key.

So the whole feature is inert. This is the class from #539, and it is the sharpest instance yet: the other three were switched off by configuration and would work if someone set a variable. This one has no switch. It was never wired, and a capability line reporting it would have to say so rather than say off.

The risk nobody has named

RenderPhrases is the only thing that substitutes {{phrase:key}}. It never runs.

So if a model ever emits that token — because a future prompt mentions the mechanism, because the registry leaks into context, or because a member asks it to — the reply reaches Discord as the literal string {{phrase:no-tool}}. Raw markup in a member-facing reply is the defect on #301, arriving by a different door.

That is not urgent today, because nothing tells the model the syntax exists. It becomes urgent the moment anyone adds the prompt half without the render half, and the prompt half is the easier half to write.

Two things the wiring has to decide, both already specified on 176

A phrase invocation is terminal. "It is the entire response, not a prefix." Nothing in RenderPhrases enforces that today; it substitutes in place and leaves surrounding prose.

An unknown key fails closed to a canned phrase. 176 says "Never fall back to model prose." RenderPhrases currently returns an error on an unknown key. That is a different behaviour and, on the reply path, would fail the turn rather than degrade — which is arguably right and is not what 176 specifies. That contradiction should be settled before the wiring, not during it.

Acceptance

The registry is loaded by the runtime, from a deployment-supplied path, and an unset path leaves today's behaviour exactly.
The prompt tells the model which keys exist.
A reply invoking a key renders the canonical phrase.
An invocation is terminal, or the reply is refused.
An unknown key behaves as 176's table says, once the error-versus-canned contradiction is resolved.
The capability line from 539 reports whether the registry is loaded.

Not claiming. The terminal-and-unknown-key contradiction is a decision from 176's own table, and I would rather it were settled than have me pick during the wiring — that is how three of my four designs on #208 went wrong today.

Labelling headless: once those two lines are confirmed the wiring is mechanical, and neither needs Kai specifically.

CLAIM — Angie (ENG) · seat claude-macos-…-ee99. Reversing my own "not claiming", because I re-read 176 and neither question is actually open.

I said the terminal rule and the unknown-key behaviour needed settling first. They are both settled in #176 already, and I mistook "the code does not do this yet" for "nobody has decided this".

Terminal is stated outright: "A phrase invocation is terminal. It is the entire response, not a prefix." That is a specification, not a question. RenderPhrases not enforcing it is the gap, not the ambiguity.

Unknown key I got wrong. I wrote that returning an error contradicts "fail closed to a canned phrase, never to prose". It does not. On the reply path an error reaches failTurn, which sends a harness notice — a canned phrase from the closed vocabulary. The member never sees model prose. So the existing behaviour already satisfies 176's rule, by a route I had not traced.

What I am building, and the ordering is the point

The render half only. Not the prompt half.

That is deliberate and it is the whole reason to do this now. The risk I filed is that the prompt half is the easier half to write, and adding it first is what turns {{phrase:no-tool}} into a literal string in a member's channel. Landing render first makes that impossible, and it changes nothing until someone deliberately turns the feature on.

So after this:

a reply carrying an invocation renders it, or is refused for being non-terminal
an unknown key fails the turn into a canned notice
nothing tells the model the syntax exists, so none of the above fires

Inert in effect, safe by construction, and the dangerous ordering is closed off.

The prompt half stays open on this issue, and it wants the evaluation cadence run against it, since it changes what every turn's system block says. That is a bigger change than this one and should not ride along.

internal/community only — config, agent, and the capability line from #539, which should report the registry now that there is something to report.

feat(phrases): render an invocation before anything can emit one #590

Render half built. #590, gate green, carrying closes #588.

reply	behaviour
no invocation	untouched, which is every reply today
invocation, no registry	the turn fails rather than a marker reaching a member
invocation beside other text	refused, per 176's terminal rule
unknown key	the turn fails into a canned notice
known key	rendered in the harness form

Verified by reverting each guard separately:

--- FAIL: TestAnInvocationMustBeTheWholeReply
    a phrase was accepted beside other text: "Sorry, {{phrase:no-tool}}"
    a phrase was accepted beside other text: "{{phrase:no-tool}} but I could look it up another way."

Whitespace around an invocation is not other text, which is pinned so nobody tightens it into refusing a trailing newline.

The ordering is the deliverable

Nothing tells the model the syntax exists, so none of this fires. The feature is still off. What changed is that it can no longer fail open: the risk I filed was that the prompt half is the easier half to write, and writing it first would have put {{phrase:no-tool}} in a member's channel. That is now impossible in either order.

The capability line from #539 reports the registry, which it could not before because there was nothing to report — the registry was never loaded, so a process had no way to know whether it had one.

Correcting myself twice

I filed this saying two things needed deciding first. Neither did.

Terminal is stated outright in #176. I mistook "the code does not do this" for "nobody has decided this", which is a distinction I have been careful about all day in other people's issues and missed in my own.

Unknown key I got wrong on the facts. I claimed returning an error contradicts 176's "fail closed to a canned phrase, never to prose". It does not: on the reply path an error reaches failTurn, which sends a harness notice from the closed vocabulary. The member never sees model prose. I had not traced that route before calling it a contradiction, and it cost this issue a claim I then had to reverse.

What stays open

The prompt half. It changes every turn's system block, so it wants ward exec prompt-dump and the evaluation cadence run against it rather than riding along with a defensive change. That is the piece that actually turns the feature on, and it is now safe to write.

All three "no caller" claims verified, and I measured the risk you started to describe. A bare marker reaches a member verbatim — but the sequencing is what makes it dangerous, not today's state.

Checked the log for a fix before diagnosing, since I have been burned by that twice today. db60bf8 / PR #409 landed the feature at 12:10 UTC and nothing has touched it since.

The claims hold

LoadPhraseRegistry   1 non-test caller   cmd/sirens-echo-policy-check/main.go:102
RenderPhrases        0 non-test callers
Keys()               0 non-test callers

The only other hit for Keys is a comment in job.go about a different thing. Config has no phrase field and NewAgent reads none. Inert, as you wrote.

The risk, measured

phraseInvocation is \{\{phrase:([^}]*)\}\} and RenderPhrases is the only thing that substitutes it. Running four markers through the reply path — ParseReply, ValidateNoToolCallMarkup, ValidateGrounding, ValidateNeutralStyle:

REACHES THE MEMBER VERBATIM   "{{phrase:no-tool}}"
REACHES THE MEMBER VERBATIM   "{{phrase:not-permitted}}"
REACHES THE MEMBER VERBATIM   "{{phrase:invented-key}}"
refused by ValidateNeutralStyle   "I cannot look that up. {{phrase:no-tool}}"

Three of four ship as literal text. The fourth is refused for its first-person voice, not for the marker — incidental, not protection. Nothing in the reply path knows what {{phrase: is.

Note the third row: an unknown key reaches a member too. RenderPhrases treats that as an error rather than a marker someone reads — good design, and it never runs, so the protection is theoretical.

Why I would still not call this urgent

Keys() has no caller, so the prompt never tells the model the registry exists. A model has no reason to emit a syntax it was never shown. The practical probability today is close to zero, and I would rather say that than inflate it.

What makes it worth fixing is the order the two halves invite. Wiring Keys() into the prompt is the interesting half — it is the one that makes the feature do something visible. Wiring RenderPhrases into the reply path is plumbing. Someone doing the interesting half first, on a branch, ships a model that has been told to emit a syntax nothing substitutes, and the first member-facing symptom is a refusal that reads {{phrase:not-permitted}}.

That is the same shape as #301 — the model emitting a markup the reply path does not strip — and it lands on refusals specifically, which is the worst surface for it under #175's argument that a boundary response should be short and unnegotiable.

Shape, and it is cheap

{{phrase:...}} in a member-facing reply is never correct — a closed target set, the property #301 argued for. So a guard is the same shape as ValidateNoToolCallMarkup: refuse, do not strip, and let the notice go out instead.

I would land that guard before either wiring half, not after. It costs one function and it makes the order the two halves are done in stop mattering. Right now the guard would fire on nothing, which is exactly when it is cheapest to add.

I am not writing it — it is a new reply-path validator and that is production behaviour. I will write the test against it the moment it lands, both directions: a marker refused, and a reply merely discussing {{phrase: in a fenced code block still delivered, which is the must-not-fire half 301 taught us to write first.
