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 | $0.00017 | $0.02027 |
| Opus 5 | $0.00009 | $0.01014 |
| Sonnet 5 | $0.00003 | $0.00405 |
| Haiku 4.5 | $0.00002 | $0.00203 |
Grade A, and why
goga-define 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 3d 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

goga-define
Purpose
Orchestrate the product definition workflow and generate a complete PRD.
The orchestrator owns the workflow, not the product decisions.
It must keep the execution linear, delegate product work to specialized subskills, maintain the shared product context within the current agent session, detect conflicts, invoke the resolver when necessary, and finally generate the PRD.
Core Principle
The orchestrator is intentionally thin.
It must not perform product analysis itself when a specialized subskill exists for the task.
Its responsibilities are:
- initialize the product context;
- create and execute the workflow;
- pass the required context to each subskill;
- collect produced decisions;
- detect conflicts;
- invoke
goga-define-resolvewhen conflicts occur; - update the shared context after resolution;
- continue the linear pipeline;
- generate the final PRD;
- save it to the required location.
Shared Context
Maintain the product definition as an in-session context.
Do not create a separate database, persistent state store, or external context file.
Use a simple structure:
context:
product: null
input: null
problem: null
users: null
goals: null
user_experience: null
requirements: null
constraints: null
scope: null
success_criteria: null
conflicts: []
This context is the source of truth for the current execution.
Subskills consume values from this context and produce new values.
Do not add IDs, metadata, timestamps, references, or other information that is not required for product reasoning.
Subskill Contracts
Each subskill declares what it consumes and produces.
Example:
consume:
- product
- problem
- users
produce:
- goals
The orchestrator must respect these contracts.
Do not pass arbitrary context when the subskill does not require it.
Do not ask a subskill to produce information outside its declared responsibility.
Workflow
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.

goga-define is a skill published in the GitHub repository qarium/goga (29 stars, last pushed 3d ago), licensed BSD-3-Clause. It adds 17 tokens to every session and 2,027 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 2026-09-03.

doubt-driven-review
In-flight adversarial check on a non-trivial decision BEFORE it stands — distinct from post-hoc review of a finished diff. Use on "stress-test this decision", "are we sure about this", "verify before commit", "poke holes in this", when working in unfamiliar code, or before an irreversible step (migration, prod deploy…
release-cut
Cut a new pi-agent-dashboard release: promote ## [Unreleased] in CHANGELOG.md, bump every workspace package.json per SemVer, commit, tag v , and push — triggering the Release workflow that publishes every non-private workspace, builds the Electron artifacts, and creates a GitHub Release. Use on "cut a release"…
spec-coherence-check
Sweep all active OpenSpec proposals for staleness, conflicts, and obsolescence against the current codebase and archived changes. Use when proposals may be outdated, when checking cross-proposal conflicts, or before starting a batch of implementations. Produces a gap-analysis report, updates a priority queue file, and…
ship-it
Worktree-side implementation orchestrator for an OpenSpec change. Idempotent: gates automated scenarios on filesystem reality, owns the red-test fix loop, runs the docker harness with always-teardown, then drives ship-change inline. Escape hatch writes SHIPITBLOCKED.md. Runnable headless. Triggers: "ship it", "build…

Mine docs/faq.md from README.md, docs/.md, and the pi-hermes memory stores. Dispatches @fast subagents per source, dedupes against the existing FAQ, and merges entries in caveman style. Use when asked to "build / regenerate / extend the FAQ", "mine docs into FAQ", "mine hermes memory into FAQ", "surface runtime…

Turn a pi session into a Markdown "how-we-did-it" collaboration guideline: reads the session's JSONL transcript and synthesizes a reusable playbook of which prompts worked, what had to be steered, and how to reproduce the result faster.
