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.

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 | $0.00056 | $0.01349 |
| Opus 5 | $0.00028 | $0.00674 |
| Sonnet 5 | $0.00011 | $0.00270 |
| Haiku 4.5 | $0.00006 | $0.00135 |
Grade A, and why
marshal 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 — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/marshal — Session Commander
Orientation
Use Marshal when the task is:
- Multi-step but bounded (completable in one session)
- Needs investigation before action
- Spans multiple skills but doesn't need campaign persistence
- Too complex for a single skill but doesn't need Archon/Fleet
Don't use when: the task spans multiple sessions (use /archon); work decomposes into 3+ parallel streams (use /fleet); you only need research with no action (use /research).
- Parallel execution (use Fleet)
Commands
| Command | Behavior |
|---|---|
/marshal [direction] |
Full loop: understand → plan → execute → report |
/marshal assess [area] |
Read-only: understand the area, produce findings, don't fix |
Protocol
Phase 1: UNDERSTAND
Parse the user's direction into structured intent:
- Read CLAUDE.md to understand the project's architecture and conventions
- Identify: scope (which files/directories), perspective (user, developer, admin), mode (audit, fix, build, improve, map), depth (surface scan vs deep investigation)
- If the direction is ambiguous, make a reasonable interpretation and state it. Do NOT ask clarifying questions unless genuinely stuck.
Phase 2: PLAN CHAIN
Map the intent to a sequence of actions:
| Direction Pattern | Chain |
|---|---|
| "audit [area]" | explore → analyze → report findings |
| "fix [thing]" | investigate root cause → fix → verify → report |
| "map [area]" | read files in parallel → synthesize → produce analysis |
| "improve [area]" | audit current state → identify gaps → implement → verify |
| "what should [X] be" | research → analyze options → recommend with reasoning |
| "research [topic]" | search codebase + web → synthesize → report |
Announce the chain before executing: "I'll [step 1], then [step 2], then [step 3]."
Phase 3: EXECUTE
For each step in the chain:
- Load the relevant skill if one exists (e.g.,
/reviewfor audit steps) - Gather context: read relevant files, check git history, search for patterns
- Perform the action
- Check the result against the plan — did it produce what was expected?
- If a step fails, try one alternative approach before escalating
What ships with it
2 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.

marshal is a skill published in the GitHub repository SethGammon/Citadel (916 stars, last pushed yesterday), licensed MIT. It adds 56 tokens to every session and 1,349 once invoked, about $0.0003 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.
