OpenSpec Bulk Change Archiver
Fission-AI/OpenSpec
Archives several completed OpenSpec changes in one operation, checking the codebase to resolve spec conflicts rather than archiving blindly.
Implements every @spec fact from a project's fact sheet in code, tags each one @implemented once done, and reports exactly what is left if it cannot finish.

At a glance
Implements every @spec fact from a project's fact sheet in code, tags each one @implemented once done, and reports exactly what is left if it cannot finish.
- Works in 6 steps: Load the full spec → Identify remaining work → Plan → …
- Implementing the unimplemented @spec facts in a fact-driven project
- SKILL.md covers Goal, Process, Guidelines and Example session
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
The agent starts by running facts list to read the whole specification, including the domain section that defines the project's vocabulary, so it can reason about ordering using the same entity names the spec uses. It then runs facts check to see which command-facts currently pass or fail, and facts list --tags "spec" to get the actual set of facts ready to implement; a spec fact that already passes its check is verified and transitioned rather than re-implemented.
Only @spec facts are implemented. @draft facts are left for a separate facts-refine skill, and untagged facts are treated as already true or flagged for triage with facts-discover. The agent plans an implementation order from dependencies and section grouping, groups independent facts into parallel batches for subagents, and implements sequential ones in order. Short CLI aliases such as ll, at, rt, rm and ls are available for frequent operations.
When your agent uses it
- Implementing the unimplemented @spec facts in a fact-driven project
- Building code from a fact sheet rather than a prose specification
- Checking which facts already pass validation before writing new code
Example prompts
- “Implement all the spec facts in this project.”
- “Work through the unimplemented requirements in the fact sheet and tag what you finish.”
- “Run facts check and implement whatever is still failing.”
Requirements
- The facts CLI
Workflow steps
6 steps, taken from the step headings in SKILL.md.
- Load the full spec
- Identify remaining work
- Plan
- Implement
- Verify
- Handle problems
What it can do on your machine
Read from SKILL.md and the folder at commit 2bf50c9. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Facts Implementer loads about 1.3k tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 612 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 612 words (~1,273 tokens).
“You are a fact-driven implementer. Your job is to take @spec facts and implement them in code — systematically, in a single session. This is the @spec → @implemented lifecycle transition.”

It then runs facts check to see which command-facts currently pass or fail, and facts list --tags "spec" to get the actual set of facts ready to implement; a spec fact that already passes its check is verified and transitioned rather than re-implemented.
When should I use Facts Implementer?
Facts Implementer fits situations like: implementing the unimplemented @spec facts in a fact-driven project; building code from a fact sheet rather than a prose specification; checking which facts already pass validation before writing new code.
How do I install Facts Implementer in Claude Code?
Run `npx skills add av/mi --skill facts-implement -a claude-code`. Or copy the skill folder (.agents/skills/facts-implement in av/mi) into .claude/skills/facts-implement in your project. Claude Code loads it when a task matches its description.
How do I install Facts Implementer in Codex?
Run `npx skills add av/mi --skill facts-implement -a codex`. Or copy the skill folder (.agents/skills/facts-implement in av/mi) into .agents/skills/facts-implement in your project. Codex loads it when a task matches its description.
Can I use Facts Implementer in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add av/mi --skill facts-implement -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/facts-implement, .gemini/skills/facts-implement, .github/skills/facts-implement and .opencode/skills/facts-implement in your project.
What does Facts Implementer need to run?
SKILL.md names no scripts, command-line tools or credentials: Facts Implementer is instructions for the agent only. Our summary lists: The facts CLI.
Does Facts Implementer access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Facts Implementer safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Facts Implementer use?
No licence was found for Facts Implementer or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Facts Implementer use?
About 1.3k tokens (SKILL.md is roughly 5.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Facts Implementer?
Skills that share tags, products or a category with Facts Implementer: OpenSpec Bulk Change Archiver (Fission-AI/OpenSpec, 71k stars), Speckit Constitution (WeihanLi/WeihanLi.Common, 242 stars), Speckit Analyze (kunstmusik/blue, 154 stars) and Speckit Plan (kunstmusik/blue, 154 stars).
