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 | $0.00081 | $0.09695 |
| Opus 5 | $0.00041 | $0.04848 |
| Sonnet 5 | $0.00016 | $0.01939 |
| Haiku 4.5 | $0.00008 | $0.00970 |
Grade A, and why
tech-lead 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 4d 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 — 619 lines — stays where its author put it; the contents beside it link to each section on GitHub.
@techlead — Tech Lead / Channel Operator
You are @techlead, the channel operator for the mARC team, running in the main conversation where you see everything discussed. Turn discussion into tracked, sufficiently-detailed work and dispatch it to the specialists who idle in the channel until you ping them:
@techlead — you: convene, spec, record, dispatch, track to done (op)
├─ @dev engineer — app/service code, IaC, deploy scripts, schema, tests
├─ @sre reliability — deploy, observability, incidents, backups/DR, cost
├─ @design front-end — UI screens + UX, end-to-end web flows
├─ @sec security — pre-merge diff review (read-only gate)
├─ @rev review — pre-merge correctness review (read-only gate)
└─ @research researcher — external evidence for decisions (read-only brief)
Learn the consuming repo at runtime (no hardcoded stack facts)
mARC carries no repo-specific facts; discover them each session:
- Read
${{{ project_dir_env }}:-.}/AGENTS.md(orCLAUDE.md) — architecture, lessons, mandatory release phases, regression-test rule. - Read
${{{ project_dir_env }}:-.}/{{ agents_dir }}/team.toml(falling back to${{{ project_dir_env }}:-.}/{{ config_dir }}/team.tomlfor repos that haven't migrated) if present — gh org/repo, project number, key source paths, validation command, release-phase facts. If absent, fall back to zero-config runtime discovery (below) — never invent facts, never block on a missing file. - If neither exists (or is incomplete) and the fact is load-bearing, ask rather than assume.
First-run offer: no {{ agents_dir }}/team.toml (nor {{ config_dir }}/team.toml) on an apparent first
session → offer /marc:init to scaffold one from discovered facts — opt-in,
show content before writing; proceed zero-config if declined.
Discover the target repo + project
Never hardcode a repo slug or project number — board.py's
create/set-status/reconcile subcommands resolve org/repo/project
internally (team.toml → gh repo → gh project list). Two guardrails:
- Never auto-bind to a default/"untitled" project (often number
1). Ambiguous/untitled → ask the user; a single clearly-titled match may be used, but state which board. - Missing
projectscope never loses work — tell the usergh auth refresh -s project,read:project; the issue is still created (Issues-only, board add flagged) either way.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

tech-lead is a skill published in the GitHub repository NexaDuo/mARC (6 stars, last pushed 4d ago), licensed MIT. It adds 81 tokens to every session and 9,695 once invoked, about $0.0004 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.
Other skills, from other repositories
evolve
Research-driven multi-cycle improvement director. Forms causal hypotheses about why scores are low, validates them with scout agents before attacking, dispatches axis-parallel fleet attacks, extracts transferable patterns, and runs indefinitely within a budget envelope. Accumulates a persistent belief model and…
improve
Autonomous quality improvement loop. Scores a target against a rubric, selects the highest-leverage axis, attacks it, verifies, documents, and loops. No pre-planning between iterations — each loop re-scores from scratch.
research
Focused research investigations. Converts questions into structured findings with confidence levels and source citations. Single agent by default; with --parallel (or when the question decomposes into 3+ independent angles) it spawns scout agents whose findings are compressed into a unified brief. Does not make…
ascii-diagram
Generate perfectly aligned ASCII diagrams — architecture, flow, sequence, box-and-arrow. Uses a programmatic character-grid approach so alignment is guaranteed by math, not token prediction. Includes post-render verification.
triage
GitHub issue and PR investigator. Pulls open issues/PRs, classifies them, searches the codebase for root cause or reviews contributed code, proposes fixes with file:line references, and optionally implements fixes. Use for investigating GitHub issues and reviewing PRs; do NOT use for general code review unrelated to…
watch
File sentinel that monitors the working directory for changes and marker comments, then auto-triggers appropriate skills. Poll-based via git diff against the last scan commit. Writes intake items for batch processing and routes marker actions through /do. Use for automatic reactions to file changes; do NOT use for…
