New page concepts/session-inbox-monitor-received-msg-fp.md — sibling of delegate-task-negative-trigger-fp. Same FP family, new dimension: the carve-out is already literal+routed (NOT for handling a received message -> inter-session-peer-discipline) but the route target is not installed, so it has no competitor and the nearest in-domain skill wins anyway. Borderline (neg 2/3, EN twin clean), self-corrects on body-load. Bidirectional cross-link + index + log. New principle: a routed negative competes only if its route target is installed. Captured in the wiki (not private memory) per owner direction. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# delegate-task — literal negative triggers beat abstract carve-outs
|
||
|
||
## Symptom
|
||
|
||
`delegate-task` v0.2.0 false-positive-fired on **«создать задачу себе»** (create a task
|
||
for myself) — a self-assigned task that should route to `using-tasks`, not to cross-agent
|
||
delegation. The `delegate-task-test-trigger` run measured it at **5/5 trials** consistently
|
||
wrong (→ `delegate-task`).
|
||
|
||
## Root cause
|
||
|
||
The positive trigger list contained **«создать задачу на агента»**. A self-task phrase
|
||
**«создать задачу себе»** shares the stem **«создать задачу»**, so it literal-matched the
|
||
positive trigger. The negative clause was abstract — *"Does NOT apply when doing the work
|
||
yourself"* — and an abstract carve-out does **not** beat a literal stem-match under the
|
||
`using-superpowers` 1%-rule. Clean-context subagents *recognized* the «себе» exception in
|
||
their reasoning, yet still invoked `delegate-task` FIRST because the literal match outweighed
|
||
the abstract exclusion.
|
||
|
||
## Fix (v0.2.0 → v0.2.1, PATCH)
|
||
|
||
Make the negative **literal and routed**, so it competes head-on with the positive at the
|
||
same surface level:
|
||
|
||
> Does NOT apply to self-assigned tasks on your own board (**«создать задачу себе»**,
|
||
> **«task for myself»**, **«поставить себе задачу»** → using-tasks), to work you do
|
||
> yourself, or to workshop-internal tasks.
|
||
|
||
Plus a body disambiguator in the "Не применяется" section:
|
||
**«на агента» / «агенту» / «в проект X» = делегирование; «себе» / «myself» = своя доска.**
|
||
|
||
## Verification
|
||
|
||
Re-ran the `delegate-task-test-trigger` methodology (fresh-context subagents, simulated
|
||
available-skills registry with the new description + competitors `using-tasks` /
|
||
`using-projects-meta` / `setup-tasks` / `session-handoff`, no hint about the expected
|
||
answer):
|
||
|
||
- **Positives 5/5** — «создать задачу на агента», «поставить задачу агенту», «delegate task
|
||
to the books project», «делегировать таску», «tasks_create для проекта X» → all
|
||
`delegate-task`. No regression from the literal negative.
|
||
- **Negative «создать задачу себе на завтра» 4/5 → `using-tasks`** (was 0/5 before the fix).
|
||
The single residual miss reasoned correctly («себе» → using-tasks) but was tripped by an
|
||
eval-harness artifact (the prompt forced a skill name on line 1 *before* reasoning),
|
||
not by ambiguity in the description.
|
||
|
||
## Reusable principle
|
||
|
||
When a skill's positive triggers contain a phrase whose **stem** also appears in a sibling
|
||
skill's domain, an abstract "does NOT apply when…" clause is too weak. Put the **exact
|
||
colliding negative phrase** in the description with an explicit **→ <sibling-skill>** route.
|
||
Literal beats abstract under the 1%-rule. See also [[tdd-criteria-design]] for another
|
||
"make the bright line literal, not a judgement call" pattern.
|
||
|
||
See [[session-inbox-monitor-received-msg-fp]] for the next clause: a literal+routed negative
|
||
still fails if its **route target isn't installed** — the carve-out then has no real competitor
|
||
and the nearest in-domain skill wins anyway.
