Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00168 | $0.04924 |
| Opus 5.5 | $0.00067 | $0.01970 |
| Sonnet 5.5 | $0.00034 | $0.00985 |
| Haiku 4.5 | $0.00017 | $0.00492 |
Grade A, and why
council-policy scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 303 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Council Policy
sdlc-model-council is a cross-model council: it assesses the peer
agentic CLIs installed on this machine, keeps a project roster of how each
model performs by task type, and runs fan-out plays — the same task to
a decorrelated panel, synthesised into one attributed verdict — on top of
an in-session, uncontainerised, single-machine delegation substrate to
locally-installed peer agentic CLIs. No Archon, no Docker, no DAG. (That's
the one-line distinction from sdlc-workflows, which is Archon-
orchestrated, containerised, DAG-based delegation — reach for that plugin
instead when a task genuinely needs an isolated container or a multi-step
workflow graph; reach for this one for a single in-session hand-off to a
peer CLI, or a cross-model fan-out play, without any of that machinery.)
§3.3 Routing: sibling-plugin hand-off vs our delegation-runner
Before dispatching anything, work out whether the request is better served by an installed sibling plugin's own slash command than by our adapter. Per-vendor plugins do the per-vendor job well; our value is cross-vendor uniformity, graded postures, and fan-out — not re-implementing what a sibling plugin already does better.
Detecting whether a sibling plugin is installed — the harness-truth
signal first: the most reliable, token-free signal is whether the
sibling's own slash commands (/codex:review, /codex:adversarial-review,
/codex:rescue, /codex:transfer, /codex:status, /codex:result,
/codex:cancel; /antigravity:delegate, /antigravity:review,
/antigravity:research, /antigravity:cloud-run-debug,
/antigravity:status, /antigravity:result, /antigravity:cancel)
appear in your own available-skills listing in this session — if they're
there, the plugin is installed and invocable directly, no probing needed.
Only fall back to the ~/.claude/plugins/installed_plugins.json probe
(extdel.sh list-backends runs this for you, advisory-only, never
gating) when you can't otherwise tell — e.g. deciding what to recommend
for a different session, or writing guidance that must hold before this
session's own skill listing is available.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

council-policy is a skill published in the GitHub repository SteveGJones/ai-first-sdlc-practices (42 stars, last pushed 1mo ago), licensed MIT. It adds 168 tokens to every session and 4,924 once invoked, about $0.0007 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
