Setup pstack
Write
~/.claude/pstack-models.md
, a per-role model override sheet you include from your global
. Each pstack skill names a default model inline; the override sheet is the layer that adapts those defaults to the models you actually have access to.
Platform note. On Codex, the override sheet is
~/.codex/pstack-models.md
, the slugs are your Codex models (for example
) not
, and you load it by adding the sheet's contents to
(Codex has no
-include into a rules file). The role rows in step 5 are identical; only the slugs, the file path, and the load mechanism change. Detect Codex slugs from
(
) plus whatever the user confirms. See
.
Claude Code has no auto-applied "rules" mechanism like Cursor's
. Inclusion is explicit: the user adds a line to
(or their project
) such as:
text
@~/.claude/pstack-models.md
so the file is loaded as context for every session.
Steps
1. Detect available models
Enumerate the model slugs you can pass to an
subagent in this session — that is the dependable source. The currently available Claude models and the default panel are listed in
Models below; the quad is chosen for cross-family, cross-tier diversity, and the single-role default stays out of the panels because it already covers the single-model roles. Ask the user to confirm or paste any additional slugs they want available. Never write a real slug you have not confirmed is available. The aliases
and
are always valid even though they are not detected slugs; both mean the role runs on the parent session's model, which the
call expresses by omitting
.
2. Load current state
The default role-to-model mapping is the rule shape shown in step 5 below. If
~/.claude/pstack-models.md
already exists, read it and treat its values as the current choices. Otherwise start from those defaults.
3. Map and confirm
Show every role with its current model, marking any real slug not in the detected set as needing a choice. Ask whether to accept as-is or change specific roles, offering the detected models plus
and
as the options. Prefer
over free text. For panel roles (how critics, arena runners, architect runners, interrogate reviewers) the value is a list, and one subagent runs per entry, alias entries included, so the list length sets the count.
is also a list, but Arena selects one value from it whose model family differs from the parent's when possible.
is the default model for every worker unless a race or comparison assigns another model per arm.
4. Validate
Every real slug written must be in the detected set;
and
always pass. If a chosen real slug is not available, stop and ask again. An override pointing at a model the user cannot use breaks every delegation that reads it.
5. Write the override sheet
Write
~/.claude/pstack-models.md
with the shape below. Overwrite the whole file so re-runs stay idempotent.
markdown
# pstack model configuration
Per-role model overrides for pstack skills. Each pstack SKILL.md names its defaults in a Models section; the values here override those defaults. Delete a line to fall back to the skill default. A value of `inherit-parent` or `auto` runs that role on the parent session's model (the `Agent` call omits `model`); an alias entry in a panel list still counts toward that panel's fan-out.

6. Wire it in
If
does not already include
~/.claude/pstack-models.md
, append the
@~/.claude/pstack-models.md
line so it loads on every session. If the user prefers project scope, add the include to the project's
instead.
7. Confirm
Tell the user where the override was written and how it loads (via the
include in CLAUDE.md). Re-running this skill updates the override sheet.
