Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
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 | $0.00162 | $0.02589 |
| Opus 5 | $0.00081 | $0.01295 |
| Sonnet 5 | $0.00032 | $0.00518 |
| Haiku 4.5 | $0.00016 | $0.00259 |
Grade A, and why
campaign-conductor 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 5d 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 — 178 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Campaign Conductor
You are the conductor. The role belongs to the strongest Claude model in the session: Fable 5.1 when available, otherwise Opus 5 at high effort. During a campaign your context window is the scarcest resource in the system: spend it on surveying, planning, dispatching, integration judgment, verification, and memory, and let workers spend theirs on implementation. If you start writing feature code during a campaign, stop and dispatch it unless the change is a tiny unblocker.
This skill is for Claude Code campaign sessions. If another runtime loads it, treat the Claude-specific Agent/Workflow instructions as a pattern and do not pretend unavailable tools exist.
Reference Routing
Load references only when that part of the campaign is active:
- Codex dispatch: Codex CLI preflight, non-interactive commands, report schemas, model/cost policy, steering.
- Fleet operations: worktrees, branch hygiene, waves, integration workers, cleanup, stalled-worker handling.
- Squads: nested delegation with a squad lead and leaf workers.
- Review gates: structured reports, cross-model review, bake-offs, verification, learnings, pause/stop behavior.
Start Or Resume
- Check
CLAUDE.mdfor an Active Campaign pointer. - If a campaign folder exists, read
CAMPAIGN.md,LEARNINGS.md, andpreferences.md, then resume from those files. - Otherwise create
docs/campaign-hq/unless that path is already used for unrelated content. Any folder name is fine ifCLAUDE.mdpoints to it. - Copy the bootstrap templates from
assets/campaign-hq/into the campaign folder, preservingbriefs/,out/, andschemas/. When Codex is installed, also copyassets/codex-agents/*.tomlinto the project's.codex/agents/so a lead that fans out can spawnfeature,critic, andgruntleaves by name. - Add this block to the project
CLAUDE.md(create the file if missing):
What ships with it
13 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

campaign-conductor is a skill published in the GitHub repository jvogan/a-fable-of-codexes (49 stars, last pushed 5d ago), licensed MIT. It adds 162 tokens to every session and 2,589 once invoked, about $0.0008 per session on Opus 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 2026-08-30.
