DEPRECATED (removal target: v3.0.0) — Use ao lookup --query "topic" for on-demand learnings retrieval and phase-scoped context packets. This skill and the ao inject CLI command still work as compatibility adapters, but they are not the canonical context path and are not called from default hooks or other skills.

Inject Skill

Install & refresh (absorbed from using-agentops, ag-s43tg)

To update installed skills: re-run the install one-liner — bash <(curl -fsSL https://raw.githubusercontent.com/boshu2/agentops/main/scripts/install.sh). (There is no update skill; skill refresh is an install-script concern.)

On-demand knowledge retrieval. Not run automatically at startup (since ag-8km).

It is read-only: it only reads knowledge for injection and never writes to .agents/.

Load relevant prior knowledge into the current session as a legacy adapter.

Lease

Folded triggers (ag-s43tg wave 1): session-bootstrap + using-agentops route here

• session-bootstrap → ao session bootstrap. The Universal AgentOps init prompt

for starting or onboarding a fresh agent session is the ao session bootstrap orientation report — run it first, then pull decay-ranked context on demand with ao lookup / ao inject.

• using-agentops → this skill (skill dir removed; embedded CLI copy retired with

it). Use when asked to Explain AgentOps workflows: start with ao session bootstrap for orientation, then walk the on-demand surfaces here (ao lookup, ao inject, ao knowledge brief) for the workflow tour.

How It Works

In the default hookless startup path, no startup injection occurs. Run ao session bootstrap for the standard orientation report, then prefer ao lookup / ao inject for on-demand retrieval and bounded per-phase packets. Use /inject or ao inject only for legacy compatibility.

If you author an opt-in SessionStart hook or run a legacy hook profile, it may call:

# lean mode (MEMORY.md fresh): 400 tokens
ao inject --apply-decay --format markdown --max-tokens 400 \
  [--bead <bead-id>] [--predecessor <handoff-path>]

# legacy mode: 800 tokens
ao inject --apply-decay --format markdown --max-tokens 800 \
  [--bead <bead-id>] [--predecessor <handoff-path>]

This legacy path searches for relevant knowledge and prints a bounded summary.

Work-Scoped Injection

When --bead is provided (via HOOK_BEAD env var from Gas Town):

• Learnings tagged with the same bead ID get a 1.5x score boost
• Learnings matching bead labels get a 1.2x boost
• Untagged learnings still appear but ranked lower

Predecessor Context

When --predecessor is provided (path to a handoff file):

• Extracts structured context: progress, blockers, next steps
• Injected as "Predecessor Context" section before learnings
• Supports explicit handoffs, auto-handoffs, and pre-compact snapshots

Manual Execution

Given /inject [topic]:

Step 1: Search for Relevant Knowledge

With ao CLI:

ao lookup --query "<topic>" --limit 5

Without ao CLI, search manually:

# Global operating memory
sed -n '1,120p' ~/.agents/MEMORY.md 2>/dev/null

# Recent learnings
ls -lt .agents/learnings/ | head -5

# Recent patterns
ls -lt .agents/patterns/ | head -5

# Recent research
ls -lt .agents/research/ | head -5

# Global learnings (cross-repo knowledge)
ls -lt ~/.agents/learnings/ 2>/dev/null | head -5

# Global patterns (cross-repo patterns)
ls -lt ~/.agents/patterns/ 2>/dev/null | head -5

# Legacy patterns (read-only fallback, no new writes)
ls -lt ~/.claude/patterns/ 2>/dev/null | head -5

Step 2: Read Relevant Files

Use the Read tool to load the most relevant artifacts based on topic.

Step 3: Summarize for Context

Present the injected knowledge:

• Global principles or constraints that apply everywhere
• Key learnings relevant to current work
• Patterns that may apply
• Recent research on related topics

Step 4: Record Citations (Feedback Loop)

After presenting injected knowledge, record which files were injected for the feedback loop:

mkdir -p .agents/ao
# Record each injected learning file as a citation
for injected_file in <list of files that were read and presented>; do
  echo "{\"artifact_path\": \"$injected_file\", \"cited_at\": \"$(date -Iseconds)\", \"session_id\": \"$(date +%Y-%m-%d)\", \"workspace_path\": \"$PWD\"}" >> .agents/ao/citations.jsonl
done

Citation tracking enables the feedback loop: learnings that are frequently cited get confidence boosts during /post-mortem, while uncited learnings decay faster.

Knowledge Sources

Decay Model

Knowledge relevance decays over time (~17%/week). More recent learnings are weighted higher.

Key Rules

• Does not run automatically - default context delivery is explicit
• Context-aware - filters by current directory/topic
• Token-budgeted - respects max-tokens limit
• Recency-weighted - newer knowledge prioritized

Examples

Opt-In Hook Profile Invocation (legacy only)

Hook trigger: an externally authored or legacy session-start.sh may run at session start with AGENTOPS_STARTUP_CONTEXT_MODE=lean or legacy

What happens:

1. Hook calls ao inject --apply-decay --format markdown --max-tokens 400 (lean) or --max-tokens 800 (legacy)
2. CLI searches .agents/learnings/, .agents/patterns/, .agents/research/ for relevant artifacts
3. CLI applies recency-weighted decay (~17%/week) to rank results
4. CLI outputs top-ranked knowledge as markdown within token budget
5. Agent presents injected knowledge in session context

Result: Prior learnings, patterns, and research are available for legacy hook profiles. This is not the default AgentOps 3.0 path.

Note: In the default hookless path, run ao session bootstrap and then pull context explicitly with ao lookup or ao inject.

Manual Context Injection

User says: /inject authentication or "recall knowledge about auth"

What happens:

1. Agent calls ao lookup --query "authentication" --limit 5
2. CLI filters artifacts by topic relevance
3. Agent reads top-ranked learnings and patterns
4. Agent summarizes injected knowledge for current work
5. Agent references artifact paths for deeper exploration

Result: Topic-specific knowledge retrieved and summarized, enabling faster context loading than full artifact reads.

Troubleshooting

Knowledge Activation (merged from knowledge-activation, cp-auc)

inject and ao lookup retrieve knowledge for the current session. Activation is the complementary capability — folded in here from the former knowledge-activation skill — that operationalizes a mature .agents corpus into durable operator surfaces (beliefs, playbooks, briefings, gaps). Where inject reads, activation promotes; the two are the read and write-to-surface halves of the same flywheel. Activation is the fourth step of the global-corpus workflow:

1. $curate --mode=harvest — gather artifacts from many rigs into ~/.agents/learnings/
2. $compile — synthesize raw artifacts into .agents/compiled/
3. (optional) $curate --mode=dream overnight — bounded compounding loop
4. knowledge activation — lift compiled knowledge into playbooks, beliefs, and runtime briefings

$compile remains the hygiene loop; activation owns corpus operationalization. Use it when the problem is no longer "capture more knowledge" but: promote the strongest recurring claims into a belief system, turn healthy topics into reusable playbooks, compile a small goal-time briefing, and surface thin topics and promotion gaps before they calcify.

Command Contract

The stable product surface is the ao knowledge command family:

ao knowledge activate --goal "turn agents into usable information"  # full outer loop
ao knowledge beliefs                                                # refresh belief book only
ao knowledge playbooks                                              # refresh candidate playbooks
ao knowledge brief --goal "fix auth startup"                       # goal-time briefing
ao knowledge gaps                                                   # thin topics, promotion gaps, weak claims, next work

ao owns the belief/playbook/brief/gap product surfaces directly; the skill owns routing, sequencing, interpretation, and next-step recommendations. ao lookup and ao codex start consume these outputs as operator context — matched briefings are the preferred dynamic startup surface, while selected beliefs and healthy playbooks provide bounded supporting guidance. When a retrieved briefing, belief, or playbook changes a recommendation, record it with ao metrics cite "<path>" --type applied 2>/dev/null || true (use --type retrieved for loaded-but-unused context).

Activation Steps

1. Preflight — verify .agents/ exists. To run ao knowledge activate, verify at least one evidence substrate is present: packet builders (source_manifest_build.py, topic_packet_build.py, corpus_packet_promote.py, knowledge_chunk_build.py) under .agents/scripts/; or the harvest fallback .agents/harvest/latest.json; or the native operator surfaces (ao knowledge beliefs|playbooks|brief|gaps).
2. Consolidate evidence — run packet layers in order: source manifests → topic packets → promoted packets → historical chunk bundles. See references/knowledge-activation-dag.md for the full DAG and its trust gates.
3. Distill operator surfaces — ao knowledge beliefs then ao knowledge playbooks materialize consumer surfaces under .agents/knowledge/ and .agents/playbooks/.
4. Compile a goal-time briefing — when there is an active objective: ao knowledge brief --goal "...". Keep it small, cite source surfaces, warn when a selected topic is thin.
5. Surface gaps — ao knowledge gaps reports thin topics, missing promotions, weak claims needing review, and the next recommended mining work.
6. Full outer loop — ao knowledge activate --goal "..." sequences evidence consolidation, belief/playbook refresh, optional briefing compilation, and a gap summary in one pass.

Activation Trust Rules

• packetization is substrate, not the product
• beliefs, playbooks, and briefings are the real operator surfaces
• thin topics stay discovery-only until evidence improves
• every generated surface should name its consumer
• repeated unchanged runs should stay structurally deterministic

Activation Output Surfaces

Consumer-facing outputs: .agents/knowledge/book-of-beliefs.md, .agents/playbooks/index.md, .agents/playbooks/<topic>.md, .agents/briefings/YYYY-MM-DD-<goal>.md, .agents/retro/. Substrate surfaces: .agents/packets/, .agents/topics/, .agents/packets/chunks/catalog.jsonl.
