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 | $0.00031 | $0.00927 |
| Opus 5 | $0.00015 | $0.00464 |
| Sonnet 5 | $0.00006 | $0.00185 |
| Haiku 4.5 | $0.00003 | $0.00093 |
Grade A, and why
openspec-archive-change 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.
This is a copy
86% identical to openspec-archive-change — 19 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Archive a completed change in the experimental workflow.
Input: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
Steps
-
If no change name provided, prompt for selection
Run
openspec list --jsonto get available changes. Use the AskUserQuestion tool to let the user select.Show only active changes (not already archived). Include the schema used for each change if available.
IMPORTANT: Do NOT guess or auto-select a change. Always let the user choose.
-
Check artifact completion status
Run
openspec status --change "<name>" --jsonto check artifact completion.Parse the JSON to understand:
schemaName: The workflow being usedartifacts: List of artifacts with their status (doneor other)
If any artifacts are not
done:- Display warning listing incomplete artifacts
- Use AskUserQuestion tool to confirm user wants to proceed
- Proceed if user confirms
-
Check task completion status
Read the tasks file (typically
tasks.md) to check for incomplete tasks.Count tasks marked with
- [ ](incomplete) vs- [x](complete).If incomplete tasks found:
- Display warning showing count of incomplete tasks
- Use AskUserQuestion tool to confirm user wants to proceed
- Proceed if user confirms
If no tasks file exists: Proceed without task-related warning.
-
Assess delta spec sync state
Check for delta specs at
openspec/changes/<name>/specs/. If none exist, proceed without sync prompt.If delta specs exist:
- Compare each delta spec with its corresponding main spec at
openspec/specs/<capability>/spec.md - Determine what changes would be applied (adds, modifications, removals, renames)
- Show a combined summary before prompting
Prompt options:
- If changes needed: "Sync now (recommended)", "Archive without syncing"
- If already synced: "Archive now", "Sync anyway", "Cancel"
If user chooses sync, execute /opsx:sync logic (use the openspec-sync-specs skill). Proceed to archive regardless of choice.
- Compare each delta spec with its corresponding main spec at
-
Perform the archive
Create the archive directory if it doesn't exist:
mkdir -p openspec/changes/archiveGenerate target name using current date:
YYYY-MM-DD-<change-name>Check if target already exists:
- If yes: Fail with error, suggest renaming existing archive or using different date
- If no: Move the change directory to archive
mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name> -
Display summary
Show archive completion summary including:
- Change name
- Schema that was used
- Archive location
- Whether specs were synced (if applicable)
- Note about any warnings (incomplete artifacts/tasks)
Output On Success
## Archive Complete
**Change:** <change-name>
**Schema:** <schema-name>
**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
**Specs:** ✓ Synced to main specs (or "No delta specs" or "Sync skipped")
All artifacts complete. All tasks complete.
Guardrails
- Always prompt for change selection if not provided
- Use artifact graph (openspec status --json) for completion checking
- Don't block archive on warnings - just inform and confirm
- Preserve .openspec.yaml when moving to archive (it moves with the directory)
- Show clear summary of what happened
- If sync is requested, use openspec-sync-specs approach (agent-driven)
- If delta specs exist, always run the sync assessment and show the combined summary before prompting
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.

openspec-archive-change is a skill published in the GitHub repository justinjdev/fellowship (5 stars, last pushed 21d ago), licensed Apache-2.0. It adds 31 tokens to every session and 927 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 86% identical to openspec-archive-change, differing in 19 lines, and is treated as a copy.

great_cto
Use when the CTO describes a feature, task, or project goal. Orchestrates the full SDLC pipeline automatically based on project type.
opportunity-solution-tree
Build an Opportunity Solution Tree (OST) to structure product discovery — map a desired outcome to customer opportunities, possible solutions, and experiments. Based on Teresa Torres' Continuous Discovery Habits. Use when the team is unclear what to build next, when multiple opportunities compete, or before writing a…
done-blocked
Reusable reporting contract for any agent that hands work back to the pipeline. Forces ONE of two terminal statuses (DONE or BLOCKED) with a specific evidence shape. Stops vague "probably finished" and "kind of stuck" verdicts.
outcome-roadmap
Transform an output-focused roadmap (feature list) into an outcome-focused one. Rewrites initiatives as outcome statements reflecting user and business impact. Use when a roadmap lists features instead of results, when making a roadmap more strategic, or when communicating what success looks like vs what will be built.
pm-planning
Decomposition methodology for pm agent — turns an approved ARCH document into a Beads task list with explicit dependencies, time-boxes, and acceptance criteria. The pipeline can only orchestrate work it can see; this skill defines what "seeable work" looks like.
init
Bootstraps a project's ROADMAP.jsonl and .foreman/config.json. Asks three things — what the project is, its near-term goals, and whether the drafted roadmap looks right — then writes and commits both files, leaving every optional behavior at its built-in default. The ledger and checkpoint policy are never asked here…
