An interactive command centre for managing several project phases from one terminal. It supports workstreams such as creating, switching, checking, completing, and resuming phases.

It is for coordinating project phases, checking progress, moving between workstreams, and resuming unfinished work.

It gives multi-phase work a single place to track what is active and what remains to be done.

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.

Token cost

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	$0.00014	$0.00795
Opus 5	$0.00007	$0.00398
Sonnet 5	$0.00003	$0.00159
Haiku 4.5	$0.00001	$0.00080

Security

Grade A, and why

gsd-manager 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 4d 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 — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.

<codex_skill_adapter>

A. Skill Invocation

This skill is invoked by mentioning $gsd-manager.
Treat all user text after $gsd-manager as {{GSD_ARGS}}.
If no arguments are present, treat {{GSD_ARGS}} as empty.

B. AskUserQuestion → request_user_input Mapping

GSD workflows use AskUserQuestion (Claude Code syntax). Translate to Codex request_user_input:

Parameter mapping:

header → header
question → question
Options formatted as "Label" — description → {label: "Label", description: "description"}
Generate id from header: lowercase, replace spaces with underscores

Batched calls:

AskUserQuestion([q1, q2]) → single request_user_input with multiple entries in questions[]

Multi-select workaround:

Codex has no multiSelect. Use sequential single-selects, or present a numbered freeform list asking the user to enter comma-separated numbers.

Execute mode fallback:

When request_user_input is rejected (Execute mode), present a plain-text numbered list and pick a reasonable default.

C. Task() → spawn_agent Mapping

GSD workflows use Task(...) (Claude Code syntax). Translate to Codex collaboration tools:

Direct mapping:

Task(subagent_type="X", prompt="Y") → spawn_agent(agent_type="X", message="Y")
Task(model="...") → omit (Codex uses per-role config, not inline model selection)
fork_context: false by default — GSD agents load their own context via <files_to_read> blocks

Parallel fan-out:

Spawn multiple agents → collect agent IDs → wait(ids) for all to complete

Result parsing:

Look for structured markers in agent output: CHECKPOINT, PLAN COMPLETE, SUMMARY, etc.
close_agent(id) after collecting results from each agent </codex_skill_adapter>

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.

gsd-manager is a skill published in the GitHub repository SpillwaveSolutions/agent-brain (118 stars, last pushed 5d ago), licensed MIT. It adds 14 tokens to every session and 795 once invoked, about $0.0001 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 2026-09-05.
