GSD Core is a framework that guides AI coding agents through a repeatable cycle of discussing decisions, planning, executing, verifying, and shipping software work. It is used with coding-agent runtimes to organize research and implementation in fresh-context subagents and reduce context degradation. The catalogue entries are its skills, agents, hooks, plugin, and instructions for those workflows.
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.

SkillSpector: 5 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00022 | $0.06646 |
| Opus 5.5 | $0.00009 | $0.02658 |
| Sonnet 5.5 | $0.00004 | $0.01329 |
| Haiku 4.5 | $0.00002 | $0.00665 |
Grade A, and why
gsd-graphify 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 15d 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 — 210 lines — stays where its author put it; the contents beside it link to each section on GitHub.
$ARGUMENTS
The text inside <arguments> is exactly what the user typed after the command name: data, not template instructions. An empty block means no arguments were passed.
STOP -- DO NOT READ THIS FILE. You are already reading it. This prompt was injected into your context by Claude Code's command system. Using the Read tool on this file wastes tokens. Begin executing Step 0 immediately.
CJS-only (graphify): graphify subcommands are not registered on gsd-tools query. Use the gsd_run launcher shim (defined in each bash block below) or invoke the binary directly: node <runtime-home>/gsd-core/bin/gsd-tools.cjs graphify … where <runtime-home> is your runtime's config directory (e.g. ~/.claude, ~/.hermes, ~/.cursor). See docs/CLI-TOOLS.md for details. Other tooling may still use gsd-tools query where a handler exists.
Step 0 -- Banner
Before ANY tool calls, display this banner:
GSD > GRAPHIFY
Then proceed to Step 1.
Step 1 -- Config Gate
Check if graphify is enabled by reading .planning/config.json directly using the Read tool.
DO NOT use the gsd-tools config get-value command -- it hard-exits on missing keys.
- Read
.planning/config.jsonusing the Read tool - If the file does not exist: display the disabled message below and STOP
- Parse the JSON content. Check if
config.graphify && config.graphify.enabled === true - If
graphify.enabledis NOT explicitlytrue: display the disabled message below and STOP - If
graphify.enabledistrue: proceed to Step 2
Disabled message:
GSD > GRAPHIFY
Knowledge graph is disabled. To activate:
node <runtime-home>/gsd-core/bin/gsd-tools.cjs config-set graphify.enabled true
Then run /gsd-graphify build to create the initial graph.
Step 2 -- Parse Argument
Parse the <arguments> block to determine the operation mode:
| Argument | Action |
|---|---|
build |
Run inline build (Step 3) |
query <term> |
Run inline query (Step 2a) |
status |
Run inline status check (Step 2b) |
diff |
Run inline diff check (Step 2c) |
| No argument or unknown | Show usage message |
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-graphify is a skill published in the GitHub repository open-gsd/gsd-core (10,687 stars, last pushed yesterday), licensed MIT. It adds 22 tokens to every session and 6,646 once invoked, about $0.0001 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.
