A DESIGN DECISION THE AGENT CANNOT SETTLE FROM THE TREE GOES TO THE COUNCIL
FIRST, NOT TO THE USER FIRST. THE USER IS THE ESCALATION, NOT THE DEFAULT.
NEVER PRESENT A COUNCIL VERDICT THAT WAS NOT REACHED. AN INCONCLUSIVE RUN
IS REPORTED AS INCONCLUSIVE, AND WHATEVER YOU DECIDE INSTEAD IS LABELLED
OWN ANALYSIS.
Interrupting the user is the expensive path: it costs a round trip and their attention, and on a question two models could have settled it buys nothing they wanted to be asked. So the ordering is tree → council → user, and the council leg is the one that gets skipped.
Classes that go to the council first — each is a judgement with a real trade-off and no answer in the tree:
| Class | Example |
|---|---|
| Competing implementations of one feature | two sessions shipped the same phase; discard, overwrite, or merge |
| Which of N designs, all defensible | four declared types with a derived fifth, or five declared |
| Reopening a recorded decision | an ADR or honest-null blocks a change that now looks net-positive |
| Scope re-cut inside an authorized task | this phase splits into two, or absorbs the next |
| Is the evidence sufficient to conclude | n=1 measurement, a proxy metric, an unreplicated finding |
Classes that still go straight to the user, and the council never substitutes
for them: anything behind the Hard Floor
(non-destructive-by-default) ·
spend · a scope EXPANSION beyond what was authorized · a decision whose inputs
only the user holds (a preference, a deadline, a business constraint) · the
high_impact and user_required classes, which
ask-when-uncertain routes to the user by
Iron Law. A council cannot consent on the user's behalf, and asking it to is not
autonomy, it is laundering.
Measured 2026-08-17: a run returned 0 of 2 seats, both cli_quota_exhausted,
with the counters at 72/50 and 99/50. The CLI reported it correctly as
INCONCLUSIVE — DEGRADED and did not print a quorum it had not reached. Three
things follow, and the first is the one under pressure:
council-availability
states.agent-config council:status is free and answers availability; council_cli estimate <file> is free and answers parse-and-cost. Run both before concluding
the council is not an option — and note the question goes in a file, since
prose passed as an argument overflows the argument limit.
/council.Do NOT use when:
subagent-orchestration (in-session, no network,
no money)./team), the depth
complement to the council's breadth. The council is artefact-only and
never grants the external model repo access or the host's framing; team
mode deliberately does the opposite. Neither replaces the other.THE COUNCIL CONFIG IS ALWAYS USER-GLOBAL. NEVER SEARCH THE PROJECT FOR IT.
THE ABSENCE OF A COUNCIL FILE IN A PROJECT SAYS NOTHING ABOUT WHETHER
THE COUNCIL IS CONFIGURED. ONLY THE CLI / RESOLVER DECIDES THAT.
The council config lives at one place only:
~/.event4u/agent-config/settings/.ai-council.yml (per
ADR-104,
superseding ADR-093). It is configured once per developer and works
in every project, worktree, and CWD — including consumer repos that
carry none of this package's internals.
Before claiming the council is unavailable, you MUST run the CLI
(council:estimate) and read its exit code + message. Never conclude
"council not configured in this project" from missing project files:
scripts/ai_council (a package-internal directory, absent from every
consumer repo), .agent-settings.yml (the legacy block was removed in
ADR-093), or a project-local .ai-council.yml (never read — ADR-104).
Eyeballing the project for any of these and then deciding solo — instead
of running the resolver — is the canonical failure ADR-104 exists to stop.
The only escape from the user-global location is $AI_COUNCIL_CONFIG, an
explicit absolute path for tests / power users — still not a project search.
The Phase 6 necessity classifier (see
ai-council-config § Necessity classifier)
runs as a pre-flight gate inside the CLI and skips the council when
the prompt looks like routine work. Route around it BEFORE the gate
fires so the user never pays the classifier-pause cost on a request
that obviously did not need a council in the first place.
Skip the council and stay in-session for:
systematic-debugging or bug-investigate.typo, formatting, lint, indent,
import order, simple rename. Use the language skill directly
(php-coder, eloquent, nextjs-patterns, etc).codebase-retrieval or the docs skill,
never the council.Invoke the council when:
Agent orchestration MUST call council_cli with
--invocation agent so the gate can skip silently on routine
requests. User-typed /council keeps the default
(--invocation user_explicit); the user gets the educational message
--proceed-anyway override path. Mode block ignores
--proceed-anyway by design — cost-strict opt-in.Bring in independent external models to critique a project artefact. Independent means: the council members never see the host agent's reasoning, internal state, or framing language — only the artefact (roadmap, diff, prompt, file set) plus a neutral system prompt that asks them to think on their own merits.
THE COUNCIL NEVER SEES THE HOST AGENT'S ANALYSIS, REASONING, OR FRAMING.
ROUND 1 SEES THE ARTEFACT + THE NEUTRAL SYSTEM PROMPT. NOTHING ELSE.
ROUND 2+ MAY SEE PRIOR PEER REPLIES — ANONYMISED ONLY, NEVER ATTRIBUTED, NEVER THE HOST'S.
THE HOST AGENT IS THE CONVENER, NEVER A REVIEWER.
If you find yourself wanting to "frame" the artefact for the council,
stop. Framing is exactly what kills the second-opinion value. Use the
unbiased system prompts in scripts/ai_council/prompts.ts; do not
roll your own.
The host runs the council and synthesises convergence — it is the convener, not a reviewer. The reviewer-ban is structural: the host wrote (or framed) the artefact and cannot critique it independently. Anonymising the host as "Reviewer C" is worse than excluding it — the user is told they got an outside vote when they did not. Externals down → surface and skip; never substitute the host as a reviewer.
This skill is a router head. Everything above is true in every mode and stays
here: which decision classes reach the council at all, what to do when it cannot
answer, the user-global configuration fact, the necessity self-check, and the
neutrality Iron Law. So does the output format below — it is an ordered MUST that
a pointer cannot carry. The operational manuals live in references/; load the
one the task calls for, not the set.
| Task | Mode body | Covers |
|---|---|---|
| Pick an execution mode, or handle a degraded one | references/execution-modes.md | Manual-mode and CLI-mode UX, the cost-gate bypass for non-billable members, degradation modes |
| Run a session end to end | references/procedure.md | The neutrality context-handoff, the numbered procedure, the convener-skeptic stance, why a mechanism claim needs a probe rather than a second opinion, what this is NOT |
| Place the artefact, or render the synthesis | references/output-and-synthesis.md | Output path convention with its forbidden and exempt sets, lens-aware synthesis templates, the --prose-synthesis escape hatch, renderer lens resolution |
| Estimate or gate the spend, or check what is redacted | references/cost-and-redaction.md | Redaction expectations, cost awareness, the pre-call estimate format, the stale price-table gate, the mid-flow overrun callback |
| Multi-round debate, deep tier, advisors, replay, low-impact fast-path | references/advanced-modes.md | rounds:N debate, the deep-reasoning tier and its manual-mode parity, /council debate, Karpathy peer-review, thinking-style advisors, the decision-replay artefact, the Lightweight-QA fast-path with its own Iron Law and output markers |
Two of those bodies carry obligations a pointer cannot summarise: the
output-path convention is enforced by CI, and the Lightweight-QA fast-path
markers are required verbatim by
fast-path-marker-visibility.
Load the body before acting in either mode rather than working from memory of it.

correctness.Every council reply MUST contain, in this order:
### <provider> · <model>,

scope: (exactly which mechanism or question is settled — narrow
enough that a superficially similar but different proposal is not
silently covered) and revisit-if: (at least one concrete condition
that reopens it — new evidence class, model-generation or tooling
change, an N-th blocked encounter, or an age threshold). A lock
recorded without both lines is an authoring error. Also state
whether the disposition is settled-by-evidence (an eval ran) or
settled-by-decision (a maintainer call) — the latter is cheaper
to reopen and should say so.accept

See Critical evaluation above.user-interaction,
carrying the host verdict in each option, with "discard council
input" always present as an option.The host agent NEVER ships council output as its own reasoning, and NEVER ships the host verdict as council output. Provider attribution stays visible in the per-member sections; host verdicts stay attributed to the host.
Tally-vs-reasoned boundary. Option-level decisions (which design / approach to take) use the council stance tally — the Convergence / Divergence summary aggregates member stances across the option set. Finding-level review (is this specific bug/line real) uses the reasoned validation in
code-review(each finding stands on its own traced reason, never a vote count). The two never cross-apply — no resolving a design option by reasoned-validating one member's take, no resolving a bug finding by counting council votes. Mirrored incode-reviewso the boundary is grep-checkable from both sides.

retries one member to "complete" the council. Result: skewed sample,
hidden spend. Fix: surface partial result, stop, ask user.| Anti-pattern | Why it's wrong | Correct approach |
|---|---|---|
| "Pre-warm" the council with the agent's own analysis. | Bias attack — collapses the reviewer to a yes-man. | Send the artefact text only. |
| Paste the host-agent identity ("I am Augment / Claude Code…") | Identity primes the reviewer's model. | Neutrality preamble in prompts.ts already handles this. |
| Silently truncate a too-large bundle. | Misleads the reviewer into thinking they saw the whole thing. | Bundler raises BundleTooLarge; surface and ask for narrower scope. |
| Reuse the same SDK client across calls without re-loading the key. | Leaks the key in long-lived process state. | Each invocation builds fresh clients from load_*_key(). |
| Spend against a billable member with no configured ceiling because "the council is standing-authorized". | Standing authorization is a bound the user set once, not a blank cheque. No ceiling = nothing was authorized. | Surface the estimate and ask, exactly in that one case (Procedure § 3). |
| Re-ask per invocation once a ceiling exists. | The ceiling already carried the decision; re-asking is the approval burden this default removed. | Fan out; let on_overrun ask on breach. |
| Forward council convergence to the user as numbered options without a host verdict. | Convergence ≠ correctness; the council never saw the codebase. | Apply the Critical evaluation lens; tag every finding accept / accept-with-modification / reject / needs-input with one-line reason. |
| Reject a finding on preference, not evidence. | "I don't like this" is not a verdict. | Cite the file, line, ADR, or contract that justifies the rejection — or surface as needs-input. |
| Paraphrase council output into the host's own analysis to defend a verdict. | Strips attribution, breaches direct-answers no-invented-facts. | Verdict cites host evidence (file:line); council output stays attributed in the per-member sections. |
Both moved verbatim to
references/cost-and-redaction.md: what the
bundler's redaction pass strips, the cost-awareness rules, the pre-call estimate
format, the stale price-table gate, and the mid-flow overrun callback. A breach
without on_overrun short-circuits the remaining members — surface the partial
result and ask, never retry silently.
Multi-round debate, the deep-reasoning tier, Karpathy peer-review, thinking-style
advisors, the decision-replay artefact and the Lightweight-QA fast-path moved
verbatim to references/advanced-modes.md. Each
is opt-in and each prices higher than a single round; none is a default.
