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: 1 finding, 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 →
- medium Excessive Agency · line 4 Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.
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 | $0.00068 | $0.03285 |
| Opus 5.5 | $0.00027 | $0.01314 |
| Sonnet 5.5 | $0.00014 | $0.00657 |
| Haiku 4.5 | $0.00007 | $0.00329 |
Grade A, and why
speq-implement 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 13d 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 — 250 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Spec Implementer (Orchestrator)
Orchestrate implementation of the plan in specs/_plans/<plan-name>. Get the plan name from the user prompt. If none is given, ask.
Sub-agents do the heavy work. Each pins its own model and effort in its frontmatter:
| Sub-agent | When used |
|---|---|
implementer-agent |
Groups with no [expert] task (default) |
implementer-expert-agent |
Groups with at least one [expert] task |
code-reviewer |

Required Skills
Invoke before starting:
/speq-cli: spec discovery/speq-writing-guardrails: prose style for artifacts and GitHub text
Do not invoke coding skills (/speq-code-tools, /speq-ext-research, /speq-code-guardrails) yourself: the orchestrator never writes code. Sub-agents invoke their own required skills.
Orchestrator Role
- Create and maintain
tasks.mdfor persistence. - Spawn sub-agents for parallel task groups.
- Update task status after each sub-agent completes.
- Never implement directly. Delegate all coding work.
- Rotate sub-agents to keep context windows fresh.
- Update
tasks.mdbefore the runtime task, so the persistent state is never behind. - If a sub-agent fails, keep its tasks
[~]and report the error. Never mark[x]while a test fails.
Rotation rule: when a sub-agent has completed max_tasks_per_agent (default 5) tasks, or returns ROTATION NEEDED: read tasks.md for current state, note the completed tasks from the return, and spawn a fresh agent of the SAME type with the remaining tasks. Repeat until the group is complete.
Rotation hand-off: the outgoing agent writes a hand-off note to specs/_plans/<plan-name>/notes/<group-letter>.md (its own duty, per its Early Termination section). <group-letter> is the group's letter only — the token before the : in its Parallelization-table Group entry (group A: plan-log validation → notes/A.md), never the full group name and never a slug of it. Add one line to the fresh agent's brief: Orientation: read specs/_plans/<plan-name>/notes/<group-letter>.md first. If the note is absent, omit the line. The note is working state inside the plan directory. It is never committed evidence, and it moves into the archive with the plan directory.
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.

speq-implement is a skill published in the GitHub repository marconae/speq-skill (55 stars, last pushed 2d ago), licensed MIT. It adds 68 tokens to every session and 3,285 once invoked, about $0.0003 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 2026-08-30.

evaluate-tests
Pre-Implementation Skill Evaluator Agent (Phase 1). Executes newly generated test suites against the blank/un-implemented codebase to verify TDD baseline integrity, validate shebang interpreter lines, detect premature "False-Pass" leaks, and guarantee the test suite's validity before implementation begins.
aiops-implement
Delivery overlay — orchestrates lean ladder, tdd, prune, review with sub-phase gates; commits only on user approval.
tdd
Test-driven development — vertical red-green-refactor slices through public interfaces.
tdd
Test-driven development — write the failing test first, then the code. Triggers on TDD, test first, write tests, test-driven.
test-driven-development
Drives development with tests using the red-green-refactor loop. Use when implementing any logic, fixing any bug, or changing any behavior. Use when you need to prove that code works, when a bug report arrives, or when you're about to modify existing functionality. Use when asked to add tests to a function, fix a bug…
test-driven-development
Use when implementing any feature or bugfix, before writing implementation code.
