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 | $0.00025 | $0.00805 |
| Opus 5 | $0.00013 | $0.00402 |
| Sonnet 5 | $0.00005 | $0.00161 |
| Haiku 4.5 | $0.00003 | $0.00081 |
Grade A, and why
release_detection 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 yesterday.
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 — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Release Detection Rule
Reference: foundation/development/release_workflow.md — "Release Detection" section
Configuration is read from foundation-config.yaml.
Trigger Patterns
When a user mentions any of the following patterns, automatically detect release intent:
- "new release"
- "internal release"
- "create release"
- "release vX.Y.Z"
- "split out [features] into a [type] release"
- "prior release"
- "pre-MVP release"
- "MCP-focused release"
- "v0.X.Y release"
- Version numbers in release context (e.g., "v1.1.0", "v2.0.0")
- Release-related planning discussions
Agent Actions
Step 1: Detection and Confirmation
If context suggests a release (mentions "release", version numbers, "split out", "prior", etc.):
-
Load configuration:
- Read
foundation-config.yamlto get release settings - Check if orchestration.release is enabled
- Determine release directory structure
- Read
-
Extract release information from context:
- Release ID/version (if mentioned, e.g., "v1.0.0", "v1.1.0")
- Release type hints (internal/external, marketed/not_marketed)
- Scope hints (what features/FUs are mentioned)
-
Ask for confirmation:
I see you're requesting a new release. Should I create a release plan in `{configured_releases_directory}/in_progress/{release_id}/` following the release workflow? (yes/no)If release ID was detected, include it in the path.
-
Exception handling:
- If user explicitly says "just a spec document" or "specification only" → create a spec document instead
- If user says "no" → do not proceed with release creation
Step 2: Execute Release Workflow
If user confirms (yes):
- Load required documents:
foundation/development/release_workflow.md(primary workflow)- Skill
create-release(.cursor/skills/create-release/SKILL.mdorfoundation/agent_instructions/cursor_skills/create-release/SKILL.md) foundation/development/feature_unit_workflow.md(for FU creation, if feature units enabled)- Repository-specific execution instructions (if they exist)
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.

release_detection is a cursor rule published in the GitHub repository markmhendrickson/foundation (2 stars, last pushed 1mo ago), licensed MIT. It adds 25 tokens to every session and 805 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 2026-08-31.
