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 5.1 | $0.00037 | $0.01323 |
| Opus 5 | $0.00018 | $0.00661 |
| Sonnet 5 | $0.00007 | $0.00265 |
| Haiku 4.5 | $0.00004 | $0.00132 |
Grade A, and why
speckit-plan 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 7d 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.

User Input
$ARGUMENTS
You MUST consider the user input before proceeding (if not empty).
Spec-Forge Setup (replaces setup-plan.ps1)
- Read
.specify/feature.jsonforspec_forge_feature_id. If missing, instruct the user to run/speckit-specifyfirst and stop. - Call
get_feature_snapshotwith{ featureId }to load the current specification (must exist and be at leastin_review) and the active constitution. If the specification is stilldraft, warn the user and recommend/speckit-clarifyor re-running/speckit-specifybefore planning.
Outline
-
Load context: Use the specification and constitution loaded in Spec-Forge Setup.
-
Execute plan workflow: Draft the plan as a single structured JSON object (this replaces generating
research.md,data-model.md,contracts/,quickstart.mdas separate files — Spec-Forge stores them as sections of one versionedplandocument instead):- Fill
technicalContext(mark unknowns as"NEEDS_CLARIFICATION: ..."strings) - Fill
constitutionCheckfrom the loaded constitution (list each relevant principle and whether the plan complies; ERROR on violations unjustified) - Phase 0: Populate
research(resolve all NEEDS_CLARIFICATION) - Phase 1: Populate
dataModel,contracts,quickstart - Re-evaluate
constitutionCheckpost-design (append a second pass entry if anything changed)
- Fill
Phases
Phase 0: Outline & Research
-
Extract unknowns from
technicalContext:- For each NEEDS_CLARIFICATION → research task
- For each dependency → best practices task
- For each integration → patterns task
-
Generate and dispatch research agents:
For each unknown in Technical Context: Task: "Research {unknown} for {feature context}" For each technology choice: Task: "Find best practices for {tech} in {domain}" -
Consolidate findings into the plan's
researcharray, one entry per decision:{ "decision": "...", "rationale": "...", "alternatives": ["..."] }
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.

speckit-plan is a skill published in the GitHub repository rafaelandrade74/spec-forge (0 stars, last pushed 10d ago), licensed MIT. It adds 37 tokens to every session and 1,323 once invoked, about $0.0002 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 2026-08-31.
