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 | $0.00048 | $0.03045 |
| Opus 5.5 | $0.00019 | $0.01218 |
| Sonnet 5.5 | $0.00010 | $0.00609 |
| Haiku 4.5 | $0.00005 | $0.00304 |
Grade A, and why
metagit-context-pack 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 1mo 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 — 285 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Metagit context packs
Use this skill for the most token-efficient way to onboard into a metagit workspace.
Prefer metagit context pack --tier N --json over reading raw trees or full manifests.
Umbrella .metagit.yml stays on disk. Do not inject it: no config show --json without --confirm-full, no workspace list --include-workspace, no metagit://workspace/config?view=full without confirm=1. Maps default to 80 repos; check truncated. 500+ repos: metagit prompt workspace -k large-workspace --text-only and context-reduction.md.
Set non-interactive defaults:
export METAGIT_AGENT_MODE=true
Run from the umbrella repo that contains .metagit.yml (or pass -c path/to/.metagit.yml).
When to use
- Session start in any metagit-managed workspace
- Before editing — need project/repo boundaries and health without cloning everything
- Returning after idle — tier 2 digest shows what changed since last session
- Scoping a bugfix — tier 1 cards +
repomixprofile instead of whole-repo dumps - Coordinating humans and agents — objectives and approval queue state
Do not skip context packs and grep the filesystem when a manifest exists.
Tier workflow
| Tier | Command | Typical tokens | Contents |
|---|---|---|---|
| 0 | metagit context pack --tier 0 --json |
~100–400 | Workspace map: projects, repos, paths, clone status |
| 1 | metagit context pack --tier 1 --json |
+200–600/repo | Tier 0 + repo cards (git state, stack hints, health flags) |
| 2 | metagit context pack --tier 2 --json |
+digest | Tier 1 + session digest; updates session boundary |
Escalate tiers only when needed. Narrow tier 1/2 with --project and/or --repo.
Primary session command
metagit context pack --tier 0 --json --project P -c .metagit.yml # large umbrellas
metagit context pack --tier 2 --json --project P --repo R -c .metagit.yml
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.

metagit-context-pack is a skill published in the GitHub repository metagit-ai/metagit-cli (4 stars, last pushed 23d ago), licensed MIT. It adds 48 tokens to every session and 3,045 once invoked, about $0.0002 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 2026-08-31.
Other skills, from other repositories
memory-commit
Use when the user explicitly says "remember this", "save this", "ghi nho", "luu lai", "save for next time", or otherwise asks to persist the immediately preceding context. Captures with the appropriate contexttype (decision, preference, fact, skill, task, conversation) so future sessions can retrieve it accurately.
aget-record-lesson
Record lessons learned from sessions as persistent, searchable, committable artifacts. Classifies each lesson as Framework (help other AGETs) or Domain (help principal).
gh
GitHub CLI skill for interacting with GitHub via the gh command line tool. Use when Bub needs to (1) Create, view, or manage GitHub repositories, (2) Work with issues and pull requests, (3) Create and manage releases, (4) Run and monitor GitHub Actions workflows, (5) Create and manage gists, (6) Install and manage…
release
MUST READ before preparing a release commit or GitHub release -- the blocking GitHub preflight (dev/releasepreflight.py), project.save() versioning, changelog, README, template sync verification, fresh-install smoke, and the post-push GitHub release procedure (references/github-release.md).
memorix-git-memory
Use when the task depends on commit history, what changed, when a fix shipped, or linking engineering evidence to reasoning memory.
merge-divergent-tox
Merge or compare two divergent TouchDesigner .tox/.toe binaries that git cannot three-way-merge. Load when a merge/rebase conflicts on a .tox or .toe, when asked to merge, port, reconcile, or diff two versions of a TD component, or when comparing a component across branches, machines, or TD builds.
